I made a really tasty stout, last weekend I went to bottle after 4 weeks in primary, got a couple gallons racked into bottling bucket and saw sediment coming off the trub in the fermenter and bottling bucket. I had already added 6 oz brown sugar for priming. I saw no choice but to return beer to fermenter and let it play out another week. Ready to bottle again, cold crashed this time to avoid sediment but now my stout is getting a tart cidery taste (I already had 2 lbs sugar in grain bill) and I suspect the last 6 oz put it over top. It's still drinkable, problem is I need to prime it.........would dark dme maintain or reduce current cider taste? I'm quite certain any more table or brown sugar would make it undrinkable. Please advise.
