Im stepping up a starter in a half gallon growler and both times I seem to be losing a fair bit of yeast out the top and down the sides. About two tablespoons once it dried the first time and probably one this round Is this normal? Should I be concerned I will lose enough to affect my beer? I'm using about 1800 ml of wort so there seems to be plenty of headspace... Is just quite a bit of Krausen. When I chilled for 36 hrs (after the first overflow settled down) I had a good third of an inch of yeast left in ther growler, settled in the bottom. Thanks for your help.
