I made an all grain ingredient kit for a friend, and gave him all instructions. he did well all the things until yeast pitching. he pitched it in hot wort (he says it was 100 F).
so, since I gave him my hydrometer, he took a reading and the OG was 1.045.
in the morning fermentation started, and it is really vigorous after three days (he made a video of it and sent it to me
he used S-04 dry yeast, without rehydrating.
my question is, since it is obvious that yeast survived, and fermenting. what are consequences to expect??
off flavors? bad beer?
or maybe, very fine brew at the end?
