I’ve read that some people advocate replacing fermentation buckets every 10-15 batches, and others use theirs for much longer assuming they’re not scratched. I’ve used mine for 3 years now without replacing them; probably 15-20 batches in each one.
So, how many of you actually replace them often? If so, why?
I’m thinking of investing in some 6.5 gallon better bottles if I’m convinced that replacing the buckets is necessary. I’ve got a 5 gallon BB, but it’s not big enough. I’ve also used glass carboys before, but I don’t like the weight and the threat of breakage.
Any advice on this topic is appreciated.
