So, I made a 20 gallon batch of traditional English bitter, that I split into 4 carboys. All of the carboys turned out fine, except one that clearly has a bacterial pellicle growing on it - check out the picture. So, okay, I have tasted this beer, and so far, it tastes ENTIRELY NORMAL. What do you guys think I should do? I believe I have 3 basic choices:
- Let it proliferate and see if it sours the beer nicely, assuming it is a Lactobacillus infection?
- Try to siphon off the beer from the bottom of the carboy and stop the growth (uniikely)?
- Throw it out, because I don’t want that bacteria to touch any other brewing equipment?
