Re: leaded capsules on wine bottles

I find hstrop's response surprising, since often enough some wine
residue will attack the leaded foil, yielding soluble crystals
(acetates and tartrates, presumably). These can then combine with
the wine when it is poured, unless the crystals are cleaned off first.
Older wines routinely show some seepage around the cork and whitish
crystals where some of the capsule metal has dissolved. No longer
is the lead merely "elemental".

This all sounds familiar -- didn't it come up six months ago in this
newsgroup?
