I don't disagree but I do have a question about the blind tasting: Is it possible that knowing about a wine's age or provenance allows our brain to focus on and look for specific details? For example, you can feed me meat and I might think it is delicious but soon after if you tell me it is snake or dog meat I will vomit all over the place and find that particular taste offending. Isn't taste just a signal interpreted by the brain? I am sure you all have seen those experiments with a fake hand next to the person's but they are blocked from seeing their real hand, they start feeling touch and pain on the fake hand! Can taste also be visually and mentally affected by sight or some other knowledge?
