The GrowlerWerks uKeg Nitro makes cafe-quality cold brew attainable in your own home thanks to its compact footprint and ease of use. No need to to run tap lines or store large tanks like in homebrew setups, the uKeg Nitro utilizes sold-seperately 16-gram N2O cartridges and an integrated nitro tap and regulator cap. Portable and storeable, the uKeg Nitro holds up to 50-ounces of cold brew per batch, and can be used as a brew vessel (with the optional coffee filter bags) or to nitro charge your current cold brew setup. Each uKeg Nitro comes with a stainless steel mini keg, nitro tap, regulator cap, serving mat, and 4 coffee filter bags. Note: this listing does not include any N20 cartridges.
