Made a starter tonite about 6pm. 1L. Making a blue moon clone. At 10 pm my stirplate was not stirring, had to crank it up. Some foam on top. Not a very good smell in my opinion coming from it. Ive inly done a handful of liquid starters. Is it safe to say if it doesnt smell like something you'd drink, its probably not good? Not gonna use it if I'm not sure. It does not smell good. Can an infection happen that fast?
