I brewed an all-grain fat tire knock off and possibly first stage fermented at a bit high temp (possibly). The beer tastes off. I typically use the yeast again and again for 3 to 4 batches continuously. If the first batch is off (tastes and smells funny) can I put the second batch of wort into the leftover trub from the first batch without the same bad result. I intend to try the second batch with a lower first stage ferment temp. Also, would it help to leave the sediment in the bottom behind and only use the bottom 1" of liquid and yeast into a new better bottle????? Thanks o great ONES. Need to do second batch soon.
