I think the problem with most blind tastings is they are done as part of huge tasting events. Personally if I taste more than 4 or 5 wines at at time my palate gets "tired" and my opinion of the wine becomes very different to what I think of it after tasting it on its own.
This is a problem when you go to a wine event and try a whole bunch of different wines and decide to buy a couple of cases of the 9th or 10th wine you tasted. I will no longer buy wine after more than 5 tastings because I don't trust my judgement anymore. I really have no idea how any judge can taste 80 wines in a day and pick anything good.
you need to spit it and eat in between (preferably amidon laden stuff) to keep sharp taste buds connected to a clear mind. Especially if you are going to commit to a couple of cases.
I have tried this and it helps, but I really don't trust my palate's judgment after tasting too many wines as once.
Talking about palate destroying I once bought a wine (mid priced) that had such a terrible taste that I instantly rang to the sink to spit it out. The truly diabolic thing about this wine is it made any wine tasted for hours after this taste terrible as well (I opened 4 different wines I knew well over 3 hours as I could not believe such an effect was possible). No food or any drink could get rid of the effect. I always thought this would be the perfect wine to enter into a tasting competition.
