Nitro CO₂ Mix Gas Refill

Beer-gas blend (nitrogen and CO₂) refill — used to pour beer and nitro stouts like Guinness with a smooth, creamy head. Choose your tank size above — 5 lb, 10 lb, or 20 lb.

The 5 lb tank fits inside most standard kegerators; choose the 10 lb or 20 lb if your tank sits outside, for the most cost-effective fill. For cold brew or nitro coffee, choose our 100% Nitro Refill instead.

A refundable $125 tank deposit is added at checkout and returned in full when you bring back the empty. Available at Mike's Liquors in San Francisco for in-store pickup or Bay Area delivery.
