How to store opened beer?
Thanks for all the answers. Right now what I’m doing is just stoppering the bottle but the beer doesn’t seem the same the next day, and I suspect the loss of gas could be a big part of this – since there’s only a small amount there to start with it doesn’t take much of a reduction for it to seem completely flat. What I’m wondering now is if it might be possible to insert a plastic bag into the neck and then use a fizz keeper type product to pump the bag full of air. If it worked, it would fulfill the three requirements of not moving the beer, keeping oxygen away from the beer, and preventing CO2 from being lost into the space in the bottle.
