Does occasional alcohol make a big difference to your workout performance?

I'm not a big drinker, maybe one pint every few weeks at most. But sometimes I just feel like having one and I always end up overthinking whether it's setting me back.
I'm not just thinking about cardio either, more generally things like recovery, strength output, energy levels during WODs. Does something that infrequent even move the needle, or is the impact basically zero at that kind of frequency? Should I quit drinking fully?
