cork taint from screwcap

[Bobthebuilder]

so I've heard this is possible, the TCA coming from the barrels
Just interested to know the details of any personal experiences with this

[Wizz]

Definitely possible. Haven't experienced it myself, but have heard others talk about this, Corks are not the sole source of TCA. Wine is also not the only food that can be affected by TCA (corked carrots, anyone?)

There was one story a few years back of stelvin closures that used a thin pad of cork as the seal under the cap (this is usually some inert form of foam/plastic) which led to TCA

Beggars belief (massive facepalm)

I am sure wineries cull out old barrels that display infection with brett. I guess as you work through a winery full of barrels you know which ones are a bit dodgy. It can and does infect some barrels and not others. Almost an everyday part of wine production.

I only ever came across the one TCA effected screwcap, many years ago when some were beginning to use them with reds.

This was at (possibly the last ever) Small Winemaker's show at the Norwood Hotel in 2007, and it was the 2005 Mitolo Serpico. A few of us tried the wine and immediately said WTF?!! and double checked we were looking at a screwcap closure!

No idea what the problem specifically was, at the time we guessed maybe a TCA effected barrel, but then it could possibly have been a contaminated liner too - it seems crazy now that someone would have used stelvin closures with a thin pad of cork as the seal under the cap, but it was still relatively new some back then, and for reds a very tough sell in some circles. Still is for that matter...

Cheers,

Perhaps this is a version of the (true) story of Seppelt Show Reserve Sparkling Shiraz. The bottles were sealed at some part of the bottle fermentation process with crown seals (good) that had a cork liner (bad) and that's why there was a hiatus on releases of that line for some years due to taint in many bottles.

I've never heard of stelvin caps with a cork liner.

Not sure why the mention of brett in this thread, it's not the same as cork taint.

Bugger...hope its not the 94 Vintage you refer to Brian...probably is as this was the first release I believe with the choice of cork or crown seal.
I have a dozen under crown seal

Cheer up, since there is some cork with both the closures it shouldn't make a difference.

The '94 I opened a couple years ago had no cork under the crown seal. Magnificent wine!
