thanks guys, I've already brought them back up to the warmth of 20 degrees and can already see a little action in the bottles it's only very slight but it's there, I just did what it said in the instructions, my last batch was ok but I must admit I did try a different yeast this time it was some kind of yeast called gold or something it's supposed to set like a jelly in the bottom of the bottle so it doesn't disturb as you pour, can I also ask I always pour the full litre into a jug the first pint is always full of fizz but the second class is practically flat, is this normal ? thanks again guys
