Ok so I just read about this and was wondering if maybe my oatmeal stout had this type infection, I brewed a oatmeal stout awhile ago maybe 5-6 months ruffly and I think my target gravity was not on where it was suppose to be but still came out good. Many of my friends loved it, tasted alittle thin imo, but the others liked it. I had some still in my basement and just cracked one open and all I got is gushing, thin flavor, totally different taste- not good. I use sanstar on all of my brewing stuff, I soak all the bottles in it as well, in a 5 gallon bucket, even the caps etc. I know i didnt over carbonate, what is everyones suggestion and dose this sound like a gusher infection? I always reuse my bottles so maybe some suggestions on cleaning them better?? But the thing is I did a DIPA after this brew and it was awesome I used some of the bottles from the stout as well.
