The choice of a beer filler determines the pace of your packaging days, the preservation of your batches, and the control of oxidation (TPO).
Before selecting equipment, the brewer must define their bottling method: do you want to package an unpressurized beer intended for bottle refermentation after priming (atmospheric filling), or package a beer that is already carbonated under pressure for immediate market release (isobaric counter‑pressure filling)?
Discover our complete comparative guide to professional beer fillers, from miniature systems to high‑throughput 4‑head bottling machines.
1. Atmospheric fillers: For priming and bottle refermentation
These machines are designed for breweries that do not work under pressure or wish to perform priming before bottling:
- 3‑head stainless‑steel reservoir filler (Entry‑level): Operating by gravity with a level float, it is the most economical solution for starting out or equipping a small nano‑brewery. Robust, easy to disassemble, and fully made of sanitary stainless steel.
- Ultrafiller 1 Lite (Compact & vacuum precision): Ideal for small volumes, experimental batches, or distilleries. Thanks to its integrated vacuum pump, the liquid is drawn in without contact with mechanical parts, ensuring perfectly identical fill levels from one bottle to the next without foaming.
- Enolmaster 4‑head Stainless Steel (High‑throughput atmospheric filling): A true industrial benchmark in its category, it can reach up to 600 bottles/hour thanks to its vacuum suction system. The liquid never touches the pump, and the fill level adjusts automatically on each head.
2. Counter‑pressure fillers: For direct isobaric packaging
To bottle a clarified and already carbonated beer from an isobaric tank (Unitank or Brite Tank), the use of a counter‑pressure filler is essential to avoid foaming and to purge oxygen:
- NukaTap Counter‑Pressure Filler (Miniature & modular): An ultra‑compact counter‑pressure bottler that has the major advantage of plugging directly onto an existing NukaTap faucet. Highly customizable and modular, it is perfect for easily filling a few bottles in a taproom or for collecting lab samples.
- Facilitap (The ergonomic favorite): Designed to offer total flow control, the Facilitap combines efficient CO₂ purging with precise decompression control. Its ease of use makes it one of our favorite models for small batches and taprooms.
- IsoBrew 4‑head Bottler (The French High‑Performance reference): Designed and manufactured in France, the IsoBrew 4‑head is the best investment for growing craft breweries. It offers an ultra‑rigid aluminum/stainless‑steel frame, dual programmable CO₂ purging per head to eliminate dissolved oxygen, and a high throughput allowing 300 to 400 bottles/hour with complete reliability. Its ergonomics drastically reduce operator fatigue.
- Fast Flush CO₂ 4‑head (Very high‑end manual): Equipped with a rapid circuit‑rinse system and independent pressure gauges per head, it allows surgical control of counter‑pressure for highly carbonated or delicate beers.

| Model | Technology | Estimated Throughput | Main Advantage & Recommended Use |
|---|---|---|---|
| 3‑head Stainless Reservoir | Atmospheric / Gravity | 150 – 200 btls/hr | Low budget, classic priming on small batches. |
| Ultrafiller 1 Lite | Atmospheric / Vacuum | 100 – 150 btls/hr | High precision, zero foam, ideal for micro‑lots and lab work. |
| Enolmaster 4‑head Stainless | Atmospheric / Vacuum | Up to 600 btls/hr | High throughput for still beer, automatic level adjustment. |
| NukaTap Counter‑Pressure | Modular miniature counter‑pressure | 40 – 80 btls/hr | Plug‑and‑play on NukaTap faucet, ideal for topping up bottles. |
| Facilitap Counter‑Pressure | Ergonomic single‑head counter‑pressure | 80 – 120 btls/hr | Exceptional handling, fine degassing control. |
| IsoBrew 4‑Head (Stainless) | Semi‑manual 4‑head counter‑pressure | 300 – 450 btls/hr | Robust French design, reduced dissolved O₂, optimal profitability. |
| Fast Flush CO₂ 4‑Head | Advanced Fast‑Flush counter‑pressure | 350 – 500 btls/hr | Ultra‑precise pressure control and rapid circuit rinsing. |
Rolling Beers Technical Team Insight
Take great care with beer temperature during isobaric packaging! Even with the best counter‑pressure bottler on the market, physics always wins: beer that is too warm will degas instantly during decompression, causing excessive foaming and volume loss. For smooth, foam‑free isobaric filling, stabilize your beer in the tank between 0 °C and 2 °C at least 24 hours before bottling, and make sure your transfer lines are fully purged with CO₂ before activating the first filling head!
