If you don't know what marmite is you can stop reading now.
A friend of a friend reckons you can make marmite from the yeast leftovers of your brew. Does anyone know how to do this? Any one have a recipe?
Yes, apparently you can. There's a recipe for it here:
The author says she uses 'top fermentation from a brewery' - which I imagine is the krausen, although on a homebrew scale I wonder if that gives enough yeast.
She also mentions that it doesn't taste like the original - lacking the equipment to debitter the yeast, it's more bitter and beery. But sounded like a fun project to try.
PS: love/hate? Me, I hate Marmite! :-)
