If you want to grow a yeast from the deposit on the bottom of a bottle of a beer that ferments on the bottle, what is the best way to do that? I have tried it with some Westmalle Tripel by adding some water with sugar and i covered it with some cloth, a small Santa hat actually :) By the smell of it there is probably some alcohol in it and there is also an increase in biomass. My problem is that the texture is very different from the original deposit. The original is a fine powder and what has grown is a sort of veil. Is thia the yeast or has it become infected? The smell reminds me of coconut. Appreciate your input!
