So been enjoying my Citra blonde but I just thought to myself "this is kinda tart". Wouldn't have really phased me except that a co-worker I gave a 6-pack of my last blonde (with northern brewer instead of Citra) told me that the last two bottles tasted sour and were dumpers. Besides being very embarrassed I'm curious where the infection came from because I tried to really step up my sanitation game. I know it's probably the bottles and not the fermenter because the rest of that blonde has been pretty good. Just has me wondering because every bottle of the citra blonde has had a little tartness. Just want to rule out the fermenter, which isn't a huge deal since I just got a new fermonster. Just curious. Don't get me wrong either I actually really like the tartness in this beer. Just making sure it should be there.
