I have some red wine from a kit ready to start. Do I cover the food bucket
that I'll be using to ferment? The bucket comes with a lid, which seems to
be quite airtight (got this from a wine supply shop online). Should I use
that? I thought it shouldn't be airtight, but as you can see I am getting
confused.

This is the 3rd or 4th simple question that I've asked thus far, and the
help has been great. Thanks to all of you.
