I have mixed results with alcohol. Lately I've been following SIBO (essentially SCD & low FODMAP) and per those charts, beer is in the avoid list while things like Vodka are on the Ok occasionally column. Might be worth a try switching to a SIBO allowed alcohol, in moderation.

That said, I have never felt like beer causes significant pouchitis worsening for me. I'm sure it makes inflammation worse in general but it does not send me over the edge like lots of sugar or bread does.

I have always liked my beer and I have a few beers more than one evening during a week. I have not noticed that it causes me any issues other than now I can't handle drinking but a few. Not sure if it hits me more now that I am 40 pounds less.  I am 9 months post take down and am doing pretty well. I have not experienced any serious issues (knock on wood..lol). In a 24 hour period I am going to the bathroom 3-6 times depending on what I eat or how much I eat. I am sure this will get a little bit better as I near and go over the 1 year mark.
