Bought some cider to ferment but didn't check for preservatives. Well, it's fermenting slowly but has a buttery smell and taste. Will time clean this up as with beer fermented too hot, or am I out of luck?
ok, it's generic cider with potasium sorbate. Pitched montpellier and it ended up stuck. repitched champagne (ec-118). temps have been running cooler for most of the time, mid 60s maybe. This is first time I've ended up with a cider with preservatives and also the first time I've had a diacetyl smell/taste in cider.
