hi All,
I am having a strange thing happening to a few batches of beer I brewed. One is from back in August, the other from back in October.
they were three different recipes, came out of fermenter tasting great. Got bottled, tasted great... And I left some of them on the floor in a tiled room that has underfloor heating (which turned on without my knowing) for 6 months and now three of the batches of beer foam enormously when opened and have a strange taste that I can best describe as "carpet / carrot". The beer were fine up until a month ago.
I am wondering if the underfloor heating caused this? Can yeast autolyses do this?
Or could it be infected by something that takes a very long time to grow in the bottle (we are talking up to 6 months here) ?
I am extremely strict in my cleaning an disinfecting, using StarSan, PBW as well as regular odourless dish soap to clean out fermenters etc.
I'm scratching my head because I have never had this before...
Thanks!
