A Primer on Alternative Wine Closures

[Roy Hersh]

While I hate to open a bottle that is spoiled with TCA -- "corked" -- I am still a supporter of real cork. Nonetheless, I found this to be an interesting read on the current state of the alternatives for wine closures. Enjoy the read:

Cork is also susceptible to trichloroanisole (TCA), bacteria that can ruin a wine, dulling its flavors and giving it unpleasant off-odors (commonly known as cork taint).

A bit of a nitpick, but TCA is a chemical produced by treating a fungus with cholorinated compounds, not a bacteria.

[John M.]

No one ever mentions the fact that the non-cork ones all require the wine coming in contact with plastic or resins over a protracted period (that is if laid down).

I'd like to see a producer and roll the dice with a percentage of their vintage or lbv done in screw caps. Has this been done before? I can't recall any port of note with a screw cap except Fairbanks

It can also be produced by certain funky bacteria, but you're totally correct that that's not the issue in wine corks.

I could be wrong, but I recall previously that came up here and it's a matter of IDVP law at the moment in the Douro. You're just not allowed to bottle under screwcap for Port, IIRC.

Didn't Champalimaud use screw caps or synthetic corks at some point? For some reason that seems to be popping into my mind but I can't recall exactly.
