I starterd my coopers lager yesterday and i pitched my yest a 30c a little high but i heard it better to doit a lil high then wait to long for it to cool. Tonight its at 24c there is a bout a 1/4inch ring of foam <(krausen) the kit i got uses a krausen ring not an air lock . i dont see much happening .there is a decent amout of a white sediment on the bottom of my fermentor already is that dead yeast did i kill it pitching at that temp? Im sure i allowed plenty of oxygen in my wort before pitching the muntons gold yeat not the yeast that came with the kit
