I've heard this study quoted before and found it fairly unbelievable. I can't imagine most experienced wine tasters would find tannins in white wines. It seems like this study had only 8 participants. That about explains it to me. In particular, take note of the fact that in the 10th tasting, people had big reds with heavy tannins. Assuming the 11th tasting happened shortly thereafter, those tannins won't magically disappear from your mouth in a short time. Hence, I'd wonder if there was perhaps some kind of cross-contamination caused by this. Edit: Although it does say "In the last 23 months, the Club conducted 11 blind tastings.". Perhaps these were on separate days. But still, just 8 participants. I'm confident some people bullshit about their "ability to taste/differentiate wine".
