Wayne, thanks for the thorough response. I
myself am all about doing things the right way,
but i'm currently in a small town in Colombia
and i wouldn't have the first idea where to find
a real airlock, and mail-order is out of the
question. Being my first attempt, i'm only gonna
do a tiny batch so its not a disaster if it
comes out bad. I'll let you know how it goes.

You could put a layer of food grade mineral oil
over your wine. It will not mix and will prevent
air from getting to your wine. You will,
however, have to siphon out he wine from under
the mineral oil when ready to bottle or drink.
I think in the past some used Olive oil but the
mineral oil may not get rancid over time. I have
never tried it - just read about it.
