A quick little post about my new favourite piece of equipment, a keg used as a simple stainless steel fermentor, and no that’s not a spelling mistake. Apparently a fermentor is the vessel where the fermentation takes place, while a fermenter is the agent that performs the fermentation, i.e. little yeasts. Anyway this one was simple: there was a stray 30L keg that someone was trying to get rid of, so I obliged, I removed the spear (with a little difficulty, owing to a kind of safety ‘catch’ that meant it did not simply unscrew), I gave it a good wash out, and I popped an oversized rubber carboy cap on it. This is a size larger than the standard one that fits over a 20L carboy, and I picked it up in a lovely little homebrew shop; Edina Homebrew in Edinburgh when I was passing there last year. Luckily it fits perfectly. Now I have a lovely little 30L, steel, airtight vessel for my smaller (20-25L) brews.
