I use bottle wax on wine I plan to age a year or
more. The trick is to use the right temperature.
If you get it too hot, the wax will stick to the
bottle and you have a tough time getting it off.
High temperature can also de-color the wax. If
you have patience and heat the wax slowly, you
can get it off easily by just slipping a knife
blade underneath and slipping it off. It can
then be re-used.
