Okay I'm going in..........
I've bottled and used pressure barrels before now. My Hob Goblin is going into my corny.
I am naturally carbonating so In theory I only need the CO2 to purge the air before and after racking. Then to keep pressure up after carbonation to help serve.
As you can see I have no pressure gauge.
I don't think I need one. What do you think?
