If you drink enough wine, and that means frequency, not quantity, you will eventually develop your own taste for what you enjoy. At the same time, you will also learn to judge good from bad. Will you be able to judge the individual grape or region? Probably not, but good from bad, yes. To the point that you will occasionally dump a bottle down the drain after taking the second or third sip. Not the first, because sometimes your first sip will be a lie, but by the second or third, you will decide, this bottle is not working, and you'll just dump it down the drain. Make sure to note the grape/vintner/vintage so you don't buy it again.

It is important to buy different bottles of the same grape to see how it varies across vintners and regions. It is also important to buy different grapes, because you may be surprised over time what vintages you settle on as your tastes develop.
