Whether it's overkill/expensive depends on your finances. I say "go for it", since you still might make small batches for experimenting even after you scale up (if you do). Or, if they seem like something you won't use again, sell them for sats to get another newbie-fermenter started in the craft. Or, keep one as a trophy to hang above your headboard, with the date, batch, etc written on it. Your spouse will be so pleased with the new decor! 😀😉😜
