Used this yeast for the first time yesterday on a porter. I had read that this yeast was top cropping so put a blow off tube on, this morning i took a look to find yeast quite vigorously coming out of the tube into the water. Obviously this is very active but is it bad to be losing all this yeast, will my fermentation stall due to a lack of yeast in the wort. I pitched a 1.2 liter starter into 22 liters of wort and the fermenter holds 30 liters.
