To learn about wine can be a somewhat difficult path. As with any spirit or endeavor, there is a cost to it. Whether it is in the monetary, time, or other format.
I've found that when it comes to wine, it definitely helps to taste as much as possible. However, in a realistic sense where economic factors weigh heavily on one's self, it may not be the only way to learn.
Reading can play a significant part, as can conversation and asking any and all questions inside that chat. I've found that enough people are writing about the wondrous grape, it's regions, the producers and the like that you can learn an awful lot about vino just by spending a few minutes seeing words spun by those who do a lot of tasting.
This is an article from New York Times' Eric Asimov, who I consider to be one of, if not, the top wine writer in the U.S. He's certaintly one of my personal favorites and someone who I'll go seek out what he's written to read it.
In his latest entry, Asimov talks wines of the Languedoc region of France. I always want to learn about all the different wine regions in the world, because chances are they're not something I can learn about by going to a local store and buying several bottles.
It's a bit frustrating for me that after I read about some of the wines he's tried that I can't run out to taste it for myself. Of course if I lived in New York, it may not be a problem.
But in northeast Wisconsin, it's definitely a challenge. I would suggest to those looking to try wines that you read about online to seek out some wine sellers here (or even down in Milwaukee or Madison) and see if they can't order something online for you.
Or we can all wait, corkscrews loaded, for Amazon to get its wine marketplace in order so we may order them ourselves and have them deliver it to our doorsteps.
