No, alcohol has no effect on my UC. I can drink what I want and not pay the price with my bum. Keep in mind I am not a heavy drinker but a social one. I usually can tip a few back with my friends on the weekends and at dinners. I do it all, wine, beer, mixed drinks, shots, etc... In fact I often will drink to my UC, I say "If I can't get rid if U I might I as well make a toast 2 U!"
I actually ran across a short video with a Harvard doc in it that talked about the REDUCTION in inflammation that occurs with short term use of alcohol in colitis patients. I cannot find it now, but i think it was on the Crohn's and Colitis Foundation website at one time (may have been somewhere else, but was a reputable site). It was sort of on the side bar with an unrelated article.
