Ok...it's probably not *that* bad.
I brewed a 1 gallon Rye PA on 1/19 (my very first batch) and was so hooked, I went back to my local homebrew shop to get set up for a breakfast stout and brewed it on 1/26. When I was setting up the CO2 blow-off tube on the stout, the freaking stopper fell into my beer. I grabbed the airlock and cap from the Rye PA and put it on the stout to save it (sanitized, of course). Then, I "capped" the Rye PA with a plastic bag.
The Rye PA's fermentation hasn't visibly budged since 1/22, but my instructions say I shouldn't bottle until 2/2. I know that, best case, I should get a new cap and airlock on the Rye, but time's gotten away from me (I'm a flustered grad student most days). Should I just bottle early? Is the plastic bag save going to hold me over for another day or two? Is my Rye a goner? Will my stout taste like rubber?
