I just found kegoutlet . com s go there and request ebook on cold brewing and serving coffee on draft.
I have read that PDF. While it is informative for those not educated in cold brew. The manual to keg it isn't that great. All you seem to need is a keg, valve (dual stage to really be able to monitor/control tank pressure and output pressure), nitro stout tap and the lines that should come with it. You'll either want to just get a small 2.5 gallon keg and keep it in a fridge or buy/build a kegerator. If you throw it in the fridge the aforementioned setup runs about 350 bucks? Kegerators can run 500-650 alone.
