OK, I screwed up a couple weeks back when making an AG Barleywine.
My wort volume after boil was around 6 gallons, rather than the 5.5 I was targeting (helps explain why my OG was 1.096 rather than 1.100+ I was shooting for). I pitched the wort onto a big yeast cake and used a 6.5 gallon primary fermenter to account for the large starting volume and the anticipated explosive fermentation. After two weeks of vigorous, steady fermentation, activity slowed a lot... my SG reading was 1.018 and the beer was sitting on 4" of trub, so I decided to rack into a 5 gallon carboy for a nice long secondary.
All went well except I filled my 5 gallon carboy to capacity and still had 2qts+ left! This has never happened to me. I racked that into a large beaker I'd sanitized in iodophor and capped it with a bubbler for the time being.
What do I do with it? I don't dare risk the whole batch by remixing the extras at bottling or back into a larger carboy, but I really don't want a big beaker of fermenting beer sitting around for 3-4 months either... besides, it's my yeast starter beaker.
Can I bottle it with just a smidge of reconstituted DME and keep them safe (to see if they become bottle bombs, as I'm unsure if the fermentation is complete) or just toss it?
