I've decided to go all extract (no kits) now, and taking inspiration from various members here, once I've done my LOndon Pride clone I'm thinking of doing smaller (10-12L) batches and mixing things up with some steeping and different hop additions. This way I'll get more variety to drink and also be able to learn more about ingredients and technique quicker than with big batches.
Question is, when doing smaller batches like this, do you simply halve the quantities of everything you'd use in a 23L brew (malt, grain, hops, yeast) but steep/ boil for the same length of time? And will it ferment out quicker (of course hydrometer being the test)?
