Robert T. Gonzalez, writing for io9:
The human palate is arguably the weakest of the five traditional senses. This begs an important question regarding wine tasting: is it bullshit, or is it complete and utter bullshit?
There are no two ways about it: the bullshit is strong with wine. Wine tasting. Wine rating. Wine reviews. Wine descriptions. They're all related. And they're all egregious offenders, from a bullshit standpoint.
I won't say Gonzalez is right or wrong — though I'm sure the sommeliers of the world are up in arms — but I will say that wine-tasting has always felt like black magic to me. Every time I've had a glass of wine, the only thing I taste is the harshness of the alcohol. I get no fruitiness, no grassiness, nothing. It's all just pure alcohol to my palate, and I find it very unpleasant.
