There are shows about wine and wineries on Netflix that I have watched while drinking wine. With that said, my best advice (because it's what I did) is to buy different wines in a local shop with or without the aid of shop attendants until one learns what they do or do not like. So buying the more affordable bottles is suggested with this method. In my short wine drinking time I've purchased bottles over $50 and at all points below that, but a good wine is what the consumer likes, higher cost does not mean a person will like it any better.
Tastes develop and change over time so one year I may appreciate Merlot and the next I'd rather have very cold white wines around, or, it could happen in the same day. . . The cool thing about wine is that there is so much and in so many varieties that it doesn't get old, there is always a new adventure in a newly discovered wine.
Just go drink some!
