Brew and Grow ships our 5 lb. aluminum CO2 tanks empty per federal law. We recommend checking local listings for industrial gas suppliers as providers for not only CO2 but also beer mix. (76% Nitrogen and 24% CO2)
Filled 5 lb. tanks can efficiently carbonate and serve approximately four 5 Ã¢â‚¬â€œgallon soda style kegs before gas supplies are depleted. Results may vary.
