This was a poorly written, boring article that serves to confuse rather than help people. (Disclaimer: I am in the wine industry and a professional writer.)
(1) It starts off stating that there are things you should avoid when tasting wine, but then goes on to talk about things you should do. Pick a premise and stick to it.
(2) People in the industry are trying to loosen the stuffy wine-drinking "rules" that have been in place for generations. And yet the article dictates what you must do in order to enjoy wine, rather than presenting suggestions of how to perhaps improve your experience. She is creating more pressure for wine drinkers to do the so-called right thing. There are *no* rules etched in stone about how you enjoy wine; the beauty of wine is that you make it your own experience, whatever that entails in terms of food pairing, glass choice, tasting ritual, etc.
(3) The author makes sweeping statements such as "Finish off the evening with a sweet dessert wine. Port is a wonderful choice. Make sure you choose a dessert that will compliment it." Aside from the author misspelling "complement," why not make a couple of dessert suggestions that would pair nicely with, say, a muscat or a port? She simply leaves readers hanging.
This article merely creates more questions rather than providing any real, actionable answers.

Nice article
What a nice primer for folks new to wine! It was very clear and well written. I think that sometimes people don't enjoy wine as much as they could because they are worried about doing something wrong. A list of helpful hints like this can really increase their enjoyment. Thanks, and cheers!
