I am new to home brewing, and it seems like by brew becomes very acidic or tastes a little like rubbing alchohol after I refridgerate it. I noticed this on my first batch, but I chalked it up to beginner's error. I just made a stout and it tasted great the first week after bottle fermentation was over, but the rest has been in the fridge for a week and the same thing is happening. I was really looking forward to the stout on St. Patty's Day.
Does anyone know what I might be doing wrong? I am very carefull to sanitize and store correctly, at least I think so.
Any help would be appreciated.
