Kinds of wine, how to identify same grape differences A brief explanation with beers: I love IPAs, but some of them are a disgrace to the kind, when I'll buy some, I look for the alcohol and IBU level, so I know I'll like the beer before I even buy it.

A few months ago I discovered that I also like some wines, more precisely cabernet and malbec, but unfortunately I don't find every malbec tasty. Doesn't matter if it's red or white, I like some and dislike others. 

I've been looking for a way to know if I'll like the malbec wine or not, but most of the tips I find tell me to memorize the "wine factory" I like the most, but I don't think it's a good method. 

Is there a way, a measure, like the IBU, or some other characteristics, that can help me to see if I'll like the malbec wine or not?

PS: I'm good with the cabernet, as for now, I've liked every one I tasted.
Your liking one wine over another is a purely subjective practice. This is what makes picking out wines so difficult and expensive because you have to try it before you'll really know if you like it. Some people enjoy the journey and others want to be told what to buy. My suggestion is to try as many Malbecs as you can afford. Narrow down wineries and regions that you like. Let's say you figure out you like Chilean Malbecs or Washington State ones, then I think you know that a region will have similar flavors. Unfortunately, that's probably all we can do for you. So, just get out there and taste as many as you can!
