Hello brewers. I am currently buying 15g packets of yeast. They are pretty cheap and are re-packaged Fermentis yeast from Oz. With my small batches (9 litres max) 15g is overkill. I'm using 10g, which might also be too much... So can I mix 5g S04 with 5g S05 in a British Golden ale. What do you reckon? A thoroughbred in the making, or just an ass?
