Don't mean to burst your bubble, Tom, We re-passivate our
tanks/plumbing lines whenever we have to do any welding on 'em. Ditto
if somebody's done a super high pressure gun wash or scrubbed with
scotchbrite (or equiv) pads. Those remove a significant amount of the
initial passivation, which results in minor 'rust' layer until the
repassivation re-establishes itself or until we repassivate it.

I do not know what it may add to the wine, but I can tell from the after
taste if a wine was aged in metal. It is kind of like drinking a Tab, it
tastes ok until you stop drinking then yak.


I'll bet you couldn't tell double blind whether wine was aged in stainless
steel or glass. If you're tasting something "off" in wines from metal
containers they aren't stainless steel - or at least it isn't the container
you're tasting.
