If you keg your homebrew and want to share it, enter competitions, or just stash a few bottles for later, you need a reliable way to fill bottles without losing carbonation. That is exactly what the best counter pressure bottle fillers are designed to do. These tools let you transfer beer from keg to bottle while maintaining pressure, cutting down on foam and keeping oxygen out of your finished product.
After spending weeks comparing models, reading through hundreds of user reviews on Reddit and HomebrewTalk, and testing several fillers on my own kegerator setup, I put together this guide. Whether you are filling a couple bottles for a friend or cranking out entries for a competition, there is a filler here that fits your workflow.
In this guide I cover 11 counter pressure bottle fillers available right now, from budget options under $60 to premium tools built for serious homebrewers. I break down how each one performs, what real users think, and which one makes the most sense for different brewing situations.
Top 3 Counter Pressure Bottle Fillers for 2026

- Direct faucet connection
- CO2 purge capability
- Stainless steel
Best Counter Pressure Bottle Fillers in 2026 – Quick Comparison
1. Blichmann BeerGun Bottle Filler – Best Overall Performance
Blichmann BeerGun Stainless Bottle Filler & Accessory Kit
Stainless Steel
One-Handed Operation
Includes Accessory Kit
Pros
- Very well made with quality materials
- One-handed operation
- Preserves carbonation well
- Good for bottling from keg
- Less foaming than other methods
Cons
- Pistol grip uncomfortable after extended use
- Action may not close consistently
- Cheap hose material included
The Blichmann BeerGun has been my go-to bottle filler for over a year now, and it is easy to see why it sits at the top of so many recommendation lists. The one-handed operation is a real advantage when you are holding a bottle with your other hand. You pull the trigger to purge CO2, then push forward to start the beer flow. The whole process feels intuitive after the first couple bottles.
I have used this filler on everything from light pilsners to heavy stouts, and carbonation preservation is consistently solid. Blichmann engineered this to be simpler than traditional counter pressure fillers, and that simplicity pays off when you are filling 20 or more bottles in a session. The stainless steel construction gives me confidence that this tool will last for years.

Where the BeerGun falls short is the included hoses. Multiple users on HomebrewTalk and Reddit mention swapping them out for higher quality tubing right away. The pistol grip also gets uncomfortable after about 15 bottles. If you are doing high-volume filling sessions, plan for a short break to rest your hand. The instructions could also be clearer for first-time users.
That said, for most homebrewers filling a case or two at a time, the Blichmann BeerGun delivers the best overall experience. The accessory kit includes everything you need to connect to your keg system, and the learning curve is shorter than with true counter pressure fillers.
Best For
The Blichmann BeerGun is ideal for homebrewers who want a straightforward, one-handed filling experience. If you bottle from keg regularly and value build quality and ease of use over complex pressure control, this is your tool.
What to Watch Out For
The included hoses are low quality and should be replaced. The pistol grip can cause fatigue during long sessions. Some users report inconsistent valve closure, so watch for drips between bottles.
2. Tapcooler Counter Pressure Bottle Filler – Best Direct Faucet Connection
Tapcooler Counter Pressure Bottle Filler
Direct Faucet Connection
CO2 Purge Pre/Post Fill
Stainless Steel Construction
Pros
- Direct faucet connection
- Easy setup and use
- Less cleaning than beer gun
- Good customer service
- No foaming when used correctly
Cons
- May not fit all tap brands
- Only fits glass bottles
- Extension tube may be needed
The Tapcooler takes a different approach from the BeerGun by connecting directly to your faucet. This means no separate hoses running to your keg, which makes setup incredibly fast. One Reddit user summed it up perfectly: it takes about 20 seconds to set up and 20 seconds to clean. For someone like me who dreads the cleanup process, that alone is worth a lot.
In my testing, the Tapcooler produced clean fills with minimal foam once I got the pressure dialed in. The CO2 purge before and after filling does a great job of keeping oxygen out. The device feels solid in hand, and the stainless steel construction should hold up well over time.

The biggest complaint I found across forums is the sticky pressure release spring. Multiple users on HomebrewTalk mention this as a consistent issue. It does not break the functionality, but it can be annoying when you are trying to work quickly. I also found that the Tapcooler only works with standard glass bottles, not PET bottles, which limits its versatility.
Another thing to consider is faucet compatibility. The Tapcooler is designed for forward-sealing faucets, and some users with different tap brands reported needing an adapter or extension tube. Check your faucet type before buying.
Best For
The Tapcooler is perfect for homebrewers who want the fastest setup and cleanup possible. If you have a compatible forward-sealing faucet and primarily fill standard glass bottles, this filler gives you excellent value and convenience.
What to Watch Out For
Verify your faucet compatibility before purchasing. The sticky pressure release spring is a known issue that may require a workaround. It only works with glass bottles, so look elsewhere if you need PET bottle support.
3. Hgkeke Counter Pressure Bottle Filler – Best Budget Option
Hgkeke Counter Pressure Bottle Filler Stainless Steel Bottle Filler Counter Pressure Beer Bottling Wand 60psi CO2 Gauge 1/4 & 5/16 Barb Homebrew Beer Bottle Filler Hand Held Bottle Filler 3ft Hose
304 Stainless Steel
60psi CO2 Gauge
Three-Way Valve
6.6in Fill Tube
Pros
- Solid stainless steel construction
- No leak design with Teflon tape
- Pressure gauge for accurate monitoring
- Oxygen-free bottling
- Easy to use T-type stand
Cons
- Requires technique to use properly
- May need to chill bottles first
- Some defective units reported
The Hgkeke counter pressure bottle filler punches well above its weight class. For a fraction of what premium fillers cost, you get 304 stainless steel construction, a 60psi CO2 gauge, and a three-way valve design that lets you control gas and beer flow independently. I was genuinely surprised by the build quality at this price point.
The included pressure gauge is a feature usually reserved for more expensive models. It lets you dial in your fill pressure precisely, which makes a real difference in foam control. The T-type stand keeps the filler stable between bottles, and the silicone stopper creates a good seal on standard beer bottles.

The trade-off is technique. This is not a tool you can just pick up and master in five minutes. You need to understand counter pressure filling principles and practice your timing. Chilling bottles beforehand helps a lot. Some users also received defective units, though customer service seems responsive about replacements.
Once you get the hang of it, the Hgkeke produces results comparable to fillers costing twice as much. The no-leak design with included Teflon tape is a nice touch, and the 1/4-inch and 5/16-inch barbs make it compatible with most home keg setups.
Best For
The Hgkeke is the best counter pressure bottle filler for homebrewers on a budget who are willing to invest time in learning proper technique. If you want real counter pressure filling without the premium price tag, this is your best bet.
What to Watch Out For
There is a learning curve, so expect your first few bottles to be messy. Chill bottles and lines before filling for best results. Inspect the unit when it arrives to make sure everything is properly assembled and nothing is defective.
4. Nukatap Counter Pressure Bottle Filler – Best Direct Keg Connection
Nukatap® Counter Pressure Bottle Filler | Oxygen Purge Button | Telescopic Filling Stem | Slide-in-Faucet Design | Adapter for Direct Keg Connection | 8 mm Duotight
All Stainless Steel
Oxygen Purge Button
Telescopic Stem
Duotight Adapters
Pros
- All stainless steel construction
- Oxygen purge capability
- Direct keg connection adapters included
- Premium build quality
- Telescopic filling stem
Cons
- Only 1 review so far
- Newer product with limited feedback
The Nukatap counter pressure bottle filler from BREWBUILT (Kegland) is the newest option in this lineup, released in mid-2024. It brings some innovative features that set it apart from the competition. The oxygen purge button lets you flush the bottle with CO2 before filling, and the telescopic filling stem adjusts to different bottle heights without needing extensions.
What really caught my attention is the slide-in-faucet design combined with the included Ball Lock Post Adapters. This means you can connect directly to your keg via Duotight fittings, eliminating the need for complex hose routing. The 19.5-inch EVABarrier tubing included in the box is high quality, not the cheap stuff you often find bundled with other fillers.
Since this is a newer product with only one review at the time of writing, long-term reliability is an open question. However, Kegland has a solid reputation in the homebrew community, and the all-stainless construction suggests this filler is built to last. The 5.0 rating from that single review is promising.
Best For
The Nukatap is ideal for homebrewers who want the latest technology with direct keg connection capability. If you already use Duotight fittings in your keg setup and want a modern counter pressure filler with an oxygen purge button, this deserves serious consideration.
What to Watch Out For
Limited user feedback means you are an early adopter. The 11-pound shipping weight suggests this might be bulkier than other options. Make sure your faucet is compatible with the slide-in design before purchasing.
5. Cryfokt Counter Pressure Bottle Filler – Fastest Fill Speed
Cryfokt Beer Bottle Filler, No Foam Counter Pressure Bottle Filler with Removable Clip Lock 304 Stainless Steel Fast Filling Glass Bottle Filling Tool for Beer & Wine
304 SS
Clip Lock Design
50-60 Bottles Per Hour
1pct Drain Loss
Pros
- All stainless steel
- No foam counter pressure filling
- Easy to disassemble and clean
- Removable clip lock
- Efficient filling speed
Cons
- Shorter shank may need modification
- Low stock availability
The Cryfokt filler is designed for speed. It is rated to fill 50 to 60 bottles per hour with only about 1 percent drain loss. That makes it one of the fastest options in this roundup, and for homebrewers who regularly fill large batches, that speed matters. The removable clip lock design works with both PET and glass bottles, giving you flexibility that some other fillers lack.
I like the attention to detail in the design. Seal replacements can be done without full disassembly, which saves time during maintenance. The all-stainless construction feels sturdy, and the counter pressure filling method does a solid job of eliminating oxygen contact.
The shorter shank is the main concern here. Some users reported needing to modify or extend it for their kegerator setups. Stock also seems limited, so you might need to act fast if this is the one you want.
Best For
The Cryfokt is best for homebrewers who need speed and efficiency. If you regularly fill 20 or more bottles in a session and want both PET and glass bottle compatibility, the clip lock design makes this a strong contender.
What to Watch Out For
Measure your faucet and kegerator setup before ordering to confirm shank length will work. Low stock means availability can be unpredictable. The review count is still low, so long-term durability reports are limited.
6. Eagle KEG801 Counter Pressure Bottle Filler – Classic Made-in-USA Design
Eagle KEG801 Counter Pressure Bottle Filler
Three-Position Valve
12oz-22oz Bottles
Made in USA
3/16in Beer Barb
Pros
- Works as indicated
- Three-position valve control
- Extensible for larger bottles
- Made in USA
Cons
- Rubber stopper fit issues
- May have minor leaking
- Only 1 review available
The Eagle KEG801 has been around since 2015, which tells you something about its staying power. The simple three-position valve gives you clear control: off, beer flow, or CO2 flow. There are no complex mechanisms to learn, no tricky spring releases to fight with. It is a straightforward tool that does one job.
I appreciate that it is made in the USA. The design works out of the box for standard 12-ounce bottles, and you can extend it to fill 22-ounce bottles with a 1/4-inch tubing extension. The 3/16-inch beer barb and 5/16-inch gas barb are standard sizes that work with most homebrew hose setups.
The main drawback is the rubber stopper. Several users report that it does not always provide a perfect seal, which can lead to minor leaking during fills. You may need to source a replacement stopper for a better fit.
Best For
The Eagle KEG801 is a solid pick for homebrewers who want a no-frills, American-made filler with simple valve operation. If you fill standard 12-ounce or 22-ounce bottles and prefer straightforward controls over fancy features, this gets the job done.
What to Watch Out For
The rubber stopper may need replacing for a proper seal. Limited reviews mean there is not much community feedback to draw from. The design is functional but dated compared to newer options.
7. TOPINCN Counter Pressure Filler – Budget-Friendly Workhorse
TOPINCN Beer Bottle Filler Stainless Steel Counter Pressure Filler Home Brewed Filling Machine Handmade CO2 Beer Brewing Kit
304 Stainless Steel
Adjustable Pressure Relief
CO2 Flushing Valve
3ft Hose Included
Pros
- Premium 304 stainless steel
- Efficient CO2 flushing
- Adjustable pressure for perfect fill
- Fast sediment-free bottling
- Complete kit with hose
Cons
- Low stock availability
- Hoses may need cutting
- Requires practice
The TOPINCN counter pressure filler is another budget option that delivers real value. The 304 stainless steel construction is the same grade used in much more expensive fillers, and the CO2 flushing valve works efficiently to purge oxygen before filling. The side-mounted adjustable pressure relief valve gives you control over fill speed, which is a nice touch at this price.
The bottom-up filling method prevents sediment disturbance and oxidation. I found that the included 3-foot hose is long enough for most kegerator setups, though you may need to cut it to your specific configuration. Standard barbs make connection straightforward.
The main thing working against the TOPINCN is availability. It often shows low stock warnings, so if you find it available, grab it. The learning curve is similar to other counter pressure fillers at this price point.
Best For
The TOPINCN is ideal for budget-conscious homebrewers who want a complete kit out of the box. If you are new to counter pressure filling and want an affordable entry point with adjustable pressure control, this is a practical choice.
What to Watch Out For
Stock levels fluctuate, so do not hesitate when it is available. You may need to trim the included hose to fit your setup. Plan to practice with water before filling with beer to get your technique dialed in.
8. Haofy Brickman Beer Gun Filler – Budget Beer Gun Alternative
Brickman Beer Gun Filler, Beer Bottle Filler, Adjustable Counter Pressure Bottling Wand, 304 Stainless Steel Beer Homebrew Tool Kit
304 Stainless Steel
Adjustable Pressure Relief
Dual-Flow Valve
Counter Pressure Method
Pros
- 304 stainless steel construction
- Adjustable pressure for fill speed
- No sediment at bottom
- Easy valve controls
- Fast efficient homebrew bottling
Cons
- Learning curve for setup
- Limited review feedback
The Haofy Brickman beer gun filler is essentially a budget-friendly alternative to the Blichmann BeerGun. It uses a special dual-flow valve that sends both CO2 and beer through the same stainless tube to the bottom of the bottle. This design eliminates sediment at the bottom of filled bottles, which is a real problem with some cheaper fillers.
The adjustable pressure relief valve lets you control how fast the beer enters the bottle. Slower fills mean less foam, faster fills mean you are done sooner. Having that control at this price point is unexpected and welcome. The 304 stainless steel material should hold up well with proper cleaning.
The main concern is the learning curve. Several users mention that setup takes some figuring out, especially if you are new to counter pressure filling. The instructions are minimal, so expect to spend some time on HomebrewTalk or YouTube figuring out the optimal configuration for your keg setup.
Best For
The Haofy Brickman is best for homebrewers who want beer gun functionality at a budget price. If you like the idea of a dual-flow valve for sediment-free fills and do not mind a bit of setup time, this filler delivers solid results.
What to Watch Out For
Instructions are limited, so plan to do some research before your first fill session. The review count is low, so community feedback is sparse. Take time to dial in your pressure settings before committing to a full batch.
9. DYRABREST Counter Pressure Bottle Filler – Versatile Multi-Bottle Design
DYRABREST Bottle Filler,Counter Pressure Bottle Filler,Stainless Steel Beer/Wine Bottle Filler,Manual Liquid Filling Machine for Glass/Convoluted/Plastic/Wine Bottles
304 Food Grade SS
Isobaric Filling
Crystal Elbow
Wine Exhaust Valve
Pros
- Easier to use than beer gun
- Reduces foam with crystal elbow
- Works with various bottle types
- Good for small brewery use
- 304 food grade stainless steel
Cons
- No instructions included
- Weak stand
- Arm orientation may be backwards
- Requires modification
The DYRABREST filler stands out for its versatility. It works with glass bottles, convoluted bottles, plastic bottles, and wine bottles, covering a wider range than most competitors. The isobaric filling design with the wine exhaust valve and crystal elbow reduces foam effectively, which is one of the biggest headaches in bottle filling.
Users report that once properly set up, it is actually easier to use than a beer gun for extended sessions. The crystal elbow directs beer flow along the bottle wall, reducing turbulence and keeping foam to a minimum. For small brewery operations or serious homebrewers who fill multiple bottle types, this versatility is a real advantage.
The problems are real though. There are no instructions in the box, which is frustrating for a tool that requires proper assembly. The stand is weak and may not hold the filler securely. Some users found the arm orientation was backwards out of the box, requiring modification to work properly.
Best For
The DYRABREST is best for homebrewers or small-scale brewers who need to fill multiple bottle types beyond standard beer bottles. If you work with wine bottles, plastic bottles, or odd-shaped containers, the wide compatibility is a genuine advantage.
What to Watch Out For
Plan to spend extra time assembling without instructions. The stand may need reinforcement or replacement. Check the arm orientation before your first fill to avoid a mess.
10. LOYALHEARTDY Counter Pressure Bottle Filler – Wide Compatibility Option
Bottle Filler, Counter Pressure Bottle Filler, Stainless Steel Beer Bottling Machine, Handmade Beer Brewing Manual Liquid Filling Machine for Glass/Convoluted/Plastic/Wine Bottles
304 Food Grade SS
Crystal Elbow
Isobaric Filling
10-50mm Bottle Fit
Pros
- Crystal elbow reduces foam
- 304 food grade stainless steel
- Wide bottle compatibility
- Cost-effective solution
Cons
- Not true counter pressure for carbonated beer
- No instructions
- Plastic fitting may arrive broken
- Mixed build quality
The LOYALHEARTDY filler is one of the more affordable options in this roundup, and it covers a wide range of bottle sizes with its 10mm to 50mm inner diameter compatibility. The crystal elbow design does a decent job of reducing foam, and the 304 food grade stainless steel valves should resist corrosion over time.
However, I need to be upfront about what this product is and is not. Several users point out that this is not a true counter pressure filler for carbonated beer. It works more like an isobaric filler, which means results with highly carbonated beers may not match what you get from the Blichmann or Tapcooler. If you are filling still beverages or lightly carbonated drinks, it performs fine.
The build quality is inconsistent. Some users report arriving with broken plastic fittings, and the included QR code for instructions reportedly leads to a questionable website. At 3.8 stars, this is the lowest-rated product in the roundup.
Best For
The LOYALHEARTDY works for homebrewers on a tight budget who fill still beverages or lightly carbonated drinks across various bottle types. If you need wide bottle compatibility and are not filling highly carbonated beer, it can get the job done.
What to Watch Out For
This is not a true counter pressure filler for highly carbonated beer. Inspect all parts upon arrival for damage. You may need to find your own instructions or tutorial videos to get started.
11. HEEPDD Beer Bottle Filler – Simple Keg-to-Bottle Tool
Beer Bottle Filler, Stainless Steel Counter Pressure Beer Bottling Wand Home Brewed Filling Machine Handmade CO2 Beer Brewing Kit
304 Stainless Steel
Dual-Flow Valve
Pressure Relief Control
1.1 Pounds
Pros
- Valves work well and does the job
- Special valve for CO2 and beer
- Fast bottling from kegs
- No sediment
- Pressure relief for speed control
Cons
- Sharp edges on valve bodies
- Requires filing down for safe use
The HEEPDD beer bottle filler uses a straightforward approach: insert into the bottle, turn towards the CO2 tube to purge, then turn towards the beer tube to fill. The special valve sends both CO2 and beer through the same stainless tube to the bottom of the bottle, which eliminates sediment issues. It is simple and effective once you have the technique down.
The pressure relief valve on the side lets you control fill speed, and the 304 stainless steel construction feels sturdy. Users report that bottling directly from kegs is fast and efficient, and there is no sediment settling at the bottom of finished bottles.

The biggest issue is sharp edges. One reviewer specifically noted that the square valve bodies and middle fitting have sharp edges that can cause cuts. You will want to file these down before use for safety and comfort. This is a manufacturing quality issue that should have been caught, but once addressed, the filler works as intended.
Best For
The HEEPDD is best for homebrewers who want a simple, no-nonsense keg-to-bottle filler. If you do not mind doing a bit of filing on the edges and prefer a straightforward fill process, this gets the job done at a reasonable price.
What to Watch Out For
Sharp edges on the valve bodies need to be filed down before first use. The review count is very low, so long-term reliability is unknown. Check all fittings for tightness before your first filling session.
How to Choose the Best Counter Pressure Bottle Filler
Picking the right counter pressure bottle filler comes down to your brewing setup, your budget, and how often you plan to fill bottles. Here are the key factors I recommend considering before making a decision.
Faucet Compatibility
This is the single most important factor. The Tapcooler and Nukatap connect directly to your faucet, which is incredibly convenient but only works if your faucet is compatible. Forward-sealing faucets like Perlick work great. Rear-sealing faucets may need adapters. Fillers like the Blichmann BeerGun and Hgkeke connect via hoses to your keg, which is more universal but requires more setup time.
CO2 Purge Method
True counter pressure fillers purge the bottle with CO2 before filling to push out oxygen. This is critical for preserving beer freshness. Some fillers, like the Nukatap, have a dedicated oxygen purge button. Others, like the Hgkeke, use a three-way valve to control CO2 and beer flow. The method matters less than the result: you want a filler that lets you thoroughly purge the bottle before beer starts flowing.
Bottle Compatibility
Most fillers handle standard 12-ounce glass beer bottles. If you need to fill 22-ounce bombers, PET bottles, wine bottles, or cans, check compatibility before buying. The Cryfokt with its clip lock design and the DYRABREST with its wide 10mm to 50mm range offer the most flexibility. The Tapcooler is limited to glass bottles only.
Ease of Cleanup
Forum users consistently rank cleanup as a major factor in satisfaction. The Tapcooler wins here with its 20-second cleanup time thanks to the direct faucet connection. Hose-based systems like the BeerGun require flushing lines and disassembling connections. If you hate cleaning (and most homebrewers do), a faucet-connected model might be worth the extra investment.
Filling Speed
How many bottles do you typically fill in a session? If you are filling a handful for friends, speed does not matter much. If you are filling cases for competition season, the Cryfokt at 50 to 60 bottles per hour or the Blichmann BeerGun with its one-handed operation will save you significant time. Budget fillers tend to be slower because you need more care with each fill.
Budget vs. Premium
Counter pressure bottle fillers range from about $50 to $120. The Hgkeke and TOPINCN deliver genuine counter pressure filling under $60, but expect a steeper learning curve and fewer included accessories. The Blichmann BeerGun at the premium end includes a full accessory kit and has the largest user community for support. The Tapcooler sits in the middle with its unique faucet-connection advantage. Your choice depends on how much you brew and how often you bottle.
Frequently Asked Questions
What is the best counter pressure bottle filler?
The Blichmann BeerGun is widely considered the best overall counter pressure bottle filler thanks to its one-handed operation, stainless steel construction, and large community of users. For budget-conscious brewers, the Hgkeke counter pressure filler delivers excellent value with a 60psi CO2 gauge and three-way valve design. The Tapcooler is the best option for direct faucet connection with the fastest setup and cleanup time.
How do counter pressure bottle fillers work?
Counter pressure bottle fillers work by first pressurizing the empty bottle with CO2 to match the pressure inside your keg. Once pressures are equalized, beer flows into the bottle from the bottom up through a filling tube while CO2 escapes through a relief valve. This pressure equalization prevents foaming and keeps oxygen out, preserving carbonation and freshness in your bottled beer.
What are the pros and cons of the Tapcooler vs BeerGun?
The Tapcooler connects directly to your faucet for faster setup and cleanup, but only works with compatible forward-sealing faucets and glass bottles. The Blichmann BeerGun connects via hoses for universal keg compatibility and offers one-handed operation, but requires more cleanup time and the included hoses are low quality. The BeerGun is better for high-volume filling, while the Tapcooler excels in convenience for smaller batches.
How do you use a counter pressure bottle filler?
First, chill your bottles and beer lines. Connect the filler to your keg system and CO2 supply. Insert the filler into the bottle and create a seal. Purge the bottle with CO2 for several seconds. Open the beer flow valve to begin filling from the bottom up. When the bottle is nearly full, close the beer valve and release pressure. Cap the bottle immediately to preserve carbonation. Clean the filler after each use.
Is the iTap better than the Tapcooler?
The iTap (also known as the Boel iTap) and Tapcooler are different products. The Tapcooler is more widely available and has more user reviews. iTap users report it is awesome once you learn the technique, but it has a steeper learning curve. The Tapcooler offers a simpler direct-faucet connection with faster setup. For most homebrewers, the Tapcooler is the more practical choice due to availability and community support.
Final Thoughts on Counter Pressure Bottle Fillers
Finding the best counter pressure bottle filler comes down to matching the tool to your brewing habits. The Blichmann BeerGun remains the top overall choice for its one-handed operation and build quality, backed by the largest user community in homebrewing. The Tapcooler offers the best balance of convenience and performance with its direct faucet connection and 20-second cleanup. For brewers watching their budget, the Hgkeke delivers real counter pressure filling with a pressure gauge at a fraction of the premium price.
Whichever filler you choose, remember that technique matters as much as the tool. Chill your bottles, purge thoroughly with CO2, and practice with water before committing your best homebrew. With the right filler and proper technique, you can bottle from your keg without losing the carbonation you worked hard to achieve.
