This is a brand new, filled 5LB Nitrogen Tank. It has a special barb that only works with Nitrogen regulators. As a bonus, purchasing a new Nitrogen tank gets you into our Nitrogen exchange program! When this tank is empty, visit us in store and we can swap it out for another tank!
Nitrogen is typically used for making cold brew coffee, or for pouring the perfect pint of guiness (or any stout for that matter)
In our experience, a 5LB tank is small enough to fit inside a typical keg fridge with two kegs and a regulator.
