My plastic fermenters work and were cheap, but they are getting a bit scratched and I am starting to feel abrasions when I clean them. The last batch I did in one had me worried when I saw mould in the end, but it turned out ok (thankfully). So, because it is nearly year end and the toy budget has not been fully spent yet, I was thinking about going up to stainless. The problem I have is that the SS Brewtech buckets are in either 26l or 13l sizes and I only really make 10/11l batches. Does anyone use the smaller fermenter and, if so, what is your normal batch size? Would 10l be pushing things? I could maybe find space for the bigger version, but I'd be less than half filling it.
