Jim,
Keep in mind that corks aren't the only source of TCA, just the most
common one. Barrels can also pick up a TCA contamination and (most
disastrously) even entire winery facilities can. What year was your
Grove Mill Riesling? I think that I've seen some locally and might pick
one up out of curiosity.
