The best way to learn about wine is to drink it. A lot of it. No, this isn’t us saying “get drunk all the time”, but it does mean that studying wine in a book will only get you so far. At some point, you’re going to have to crack open a bottle and take a sip.
If you’re new to wine, we recommend you try wines from varying styles and see which you think. Eliminate any you don’t like, and continue to explore those that taste good. Easy peasy.
For those who are a bit more experienced, maybe try various wines in a certain category like 2010 Pinot Noir, or California Chardonnay across vintages.
There’s no “right” way to conduct a wine tasting - any theme can be chosen. The only way to do it wrong is if you overthink it, because keep in mind…
it’s not what wine you drink, but who you drink it with.
