You guys seen this yet?? I am seriously considering backing this project. Reusable cartridge bags hold a gallon, you can swap back and forth without losing carbonation, and they will stay fresh for up to 30 days (clock starts when it’s first opened, NOT when it’s filled. This sounds like the perfect solution for someone who wants a small draft system but feels a kegerator or keezer is too expensive, too big, too hard to make, etc… if you do small 1 gal batches it’s perfect, but you could easily split a 5 gal batch into 5 cartridges. Certainly easier than bottling. Most of their marketing is aimed at the growler market but it seems just as well-suited for homebrewing.
