Nitro Chargers, Pack of 5

GrowlerWerks absolutely knocked our socks off with the nitro cold brew coffee maker they just dropped — and we've already drunk so much of it that we actually ran out of nitro cartridges. This pack includes five refill cartridges for the maker, so you (and we) can continue pouring up perfectly frothy, caffeinated goodness for the foreseeable future.

Created by a crew of beer lovers from Portland, Oregon, GrowlerWerks uses a combined 47 years of experience to design and engineer better ways to store beer. The brand's products are sold all over the world, having garnered the attention of Cool Hunting, Eater, CNN, and more.
