For nitro cold brew at home, the Royal Brew Home Keg Kit comes correct. Modeled after stout beer dispensing systems, it features a 64 or 128-ounce keg, a special nitro-gas blend and a stout-style tap that work together to create a smooth, rich body with a foamy head. Just like your favorite draft beer. It uses standard N or N2O cartridges and tools for easy cleaning are included.
