I have a dilemma. I have 5.75 gallons of lager (pitched W-34/70) in a 7 gal. Brew Bucket the ferm chamber, and in a couple weeks I'll be cold-crashing to lager for another month or so. I normally use a CO2 Harvester with 1/2 gallon canning jars to collect enough CO2 for the inevitable suck back. However, on day 2 of fermentation I discovered that CO2 Harvester leaks like a sieve--no airlock activity. I disconnected it and replaced with an s-bubble airlock with vodka.
Now that fermentation has slowed I'll need to think about dropping the temp for lagering in a few weeks, without any external reservoir of CO2 to draw from. I have not opened the Brew Bucket lid, nor have I dropped temp yet, so there should be fairly pure CO2 in there now. I have read through several threads, but not much info applying to my situation.
Difficulty: I bottle, not keg.
I see some possible solutions, but wanted to get some input from others.
1. The mylar balloon idea looks promising, as I have a tank of CO2.
2. Someone in one of those threads suggested simply plugging up with a bung. I don't recall what type of fermenter they were talking about. Not sure if that's a good idea for my Brew Bucket, as it has the regular style lid, not the pressure type. Even so, I don't know how much negative pressure it can withstand. Maybe someone knows if I could do this?
3. Get a spunding valve. That would vent off any excess pressure if there is any further yeast activity (unlikely), but in a negative pressure situation, I'm back to the problem in #2.
This is new to me, as I usually have the CO2 in those jars to draw from. Any ideas would be appreciated!
