Similarities in taste?

[VouvrayHead]

Everyone has been giving great info.
You definitely like big, fruit-driven wines.

Some things I'd recommend without repeating others:

-Be open to liking different grapes. There are absolutely going to be wines you like from other grapes. You currently like a style, which can be enforced on very different grapes, as Newsguy pointed out.

-Try a Pinotage from South Africa, a Primitivo from Southern Italy, and an Ripasso from Northern Italy when you get a chance.

-As you noticed, we're putting Cab on the "big" side, yet it seems very different from Petite Sirah, Syrah and Zin. That's because while it's often a very intense wine that can handle a lot of oak and high alcohol like those other wines, it has less in common as far as what one might call a typical flavor profile with the others than they do with each other (Although Syrah in many of its forms is also something of an outlier among that trio). This is one reason why you'll find trying to make lists and hierarchies a bit frustrating: There are A LOT of variables.

-Be prepared for your preferences to change, but always pay most attention to what you think, not what seems like the "right" thing to think.

-Keep an open mind with whites! There's a massive variety of them out there, though I feel that California as a whole is not currently as good at them as it is at reds.
