I'm about to brew this weekend and for that I've tried to make a starter for the first time. Yeast was a bit old, Nov 28, and needed a starter according to the yeast/pitch calculator. I only made a small starter, 0.5 liter (=0.13 gallons as I understand it) since that was the size of the flask I had available, but it should be sufficient. The yeast is Wyeast 1098 British Ale. I made a stirplate for it to sit on. However, I had imagined more activity in the flask than it seems to be, now 24 hours into fermentation. I was initially afraid the dead space in the flask wouldn't be enough and that yeast activity would make the kräusen to overfill. This is what it looks like though at the moment, 24 hours in: Is this what to expect? Does it look as it should? I will let it sit on the stirplate until pitching time, which probably will be on sunday. That means 72 hours from start...the instruction i read said 48 hours. Does it matter? And finally, when I smacked the smack pack, and when I shook it, I heard this fizzing sound inside it. This is only the second time I'm using liquid yeast but I don't recal hearing any fizzing on the first one. Is this normal behavior? Does it differs from strain to strain?
