Greetings satchman - I never really thought about making a NA beer, but I suppose you would use the exact same procedure as you would making an alcoholic brew, except the NA brew would not get fermented. Then, I suppose you could use Coopers Carbonation Drops to bottle condition, or use the forced method.
I suppose the brew would be quite sweet, but I’m sure you could use some adjuncts to tone it down a bit.
Interesting thought.....
