I found out the hard way the air lock bubbler is super important

One or two of these and just a little bit of other equipment is a great way to get started with some home brew wine, cider, or mead for a really low price.

A great way to make adult grape juice

Don’t insert the bubbler into the stopper far in, just some is enough, this way the stopper will not pop out.

even without the co2 gases the rubber stopper works its way out in a matter of seconds.
