I ask because I have had an idea - which is usually a bad sign. I do
the beer making, my wife does the wine. I have a bunch of beer bottles
in a wide variety of sizes from 250 ml to 660 ml. BUT, these require a
crown cork cap. What would happen if you bottled wine in a crown cork
capped bottle? Would it matter at all? Has anyone tried it? Will the
wine age OK? Presumably lying the bottle down to keep the cork wet is
irrelevant (and might rust the crown cork?)

I've done the beer bottles. It's no problem at all. Most all the caps
are plastic lined, so should not rust.

I've not aged wine in them for any extended period of time, but I don't
see why they wouldn't work for extremely long periods of time - I've
"lost" beer before and opened bottles after 5 years or more and the cap
was fine - even still had good CO2 pressure.

I HAVE seen rust around the crimped part on rare occasions - usually when
bottles were wet for some reason (in a cooler, then stored, for example).
But the rust is on the outside of the opening - NOT touching the contents
and can be wiped off before pouring.
