If you are looking at dispensing stout all you need is gas mix bottle or soda stream bottle filled with gas mix, provided regulator is a multi gas regulator will work with gas mix for stouts, and you ll need to go with Flow control Tapping system option and add stout spout to fit on the flow control tap.
Purchase was straight forward and delivery prompt.
Easy setup and seeing my first home draft stout pour out was memorable.
Still playing with gas pressure vrs temp for ideal consistency.
Cannot fault the setup - love it - Thanks Ikegger
