I have recently started doing yeast starters for my brews, I have done 6 including the two fermenting right now since i started doing them, the wort starts to noticeably ferment very quickly (a matter of hours) and the 4 i have so far tasted have no off flavors, but my fermentation's seem less vigorous, (i would like to point out at this time i am not complaining, just curious) I have less blow offs and the rolling of things inside of the carboy seem less active. It seems to me that pitching a good quantity of healthy yeast should make it more active not less. Has anyone else experienced this? Am i just doing something terribly wrong and getting lucky that I'm not having any bad outcomes?
