Biogon

Biogon beer gas — 80 % nitrogen and 20 % CO₂. It holds the pressure, makes a proper head and doesn't over-carbonate your beer. Choose 5, 8 or 20 litres depending on how many of you drink. It works for a home beer tap as well as multi-tap setups in a pub. The cylinder is new, with a valid inspection, and you can get it refilled anywhere in the EU. And it's yours — no rental fee.
