A friend very kindly got me a jam jar full of nice fresh yeast from Palmers Brewery in Dorset. Apparantly the head brewer said it was enough for a 1bbl brew so obviously have far too much. What should I do about storing it? it's currently in the fridge, should I make a starter with it or just split it down in to more manageable amounts and store in the fridge? I'm going to do a brew tomorrow to use a bit of it but ideally want to use this on a continual basis from now on rather than buying packets.
