My experience with corked corks is similar to yours, but mostly with older bottles. What I ought to do is to put out the call to Garagistes to track corked bottles to get a true sense of its impact.

What’s a little confusing about that article is its vagueness about how MDMP manifests itself. It suggests oak chips are a major culprit, but that would taint an entire barrel or carboy (vs one bottle), so that’s not what’s affecting us, or really, most wines (which manifest in single bottles, not entire bottlings). Then it also fingers “untreated corks,” which, unless there’s some technical meaning to the term, we (and most producers) also don’t use.

But as the article says, they’re just beginning to track down “R-excellencis” (the responsible bug, more aptly named R’nt-excellencis), so we’ll see what they come up with.
