So my last batch of ale of 50 litres went into carboys and I rescued maybe 250 mls of yeast . I have it in the dehydrator now. Assuming I proof it for my next ciabatta ,do you think there will be a difference taste from ordinary active dry yeast .I buy fleichman's one kilo vacumn pack all the time,I'm guessing it might be less predictable. ( might use ale in place of water to see what happens.) I once used cake yeast but it got hard to find.  Ggage
