Here are a few pics of the wine experiment. In these, you can see the bubbles and that I replaced the glove with a balloon. It's not blown up very much, unless you see it right after the jug has been moved. That shakes things up and releases quite a bit of gas. Initially I was keeping the jug in a closet in a bedroom that stays closed off. However, worrying about the temperature being too cool made me move the jug to a different room. It hasn't seemed to increase off-gassing, though.
