Question

What makes ZD Solera one of a kind?

Answer 1

If you mean ZD Abacus, you have basically answered your own question with the word "solera".

Solera refers to a blending (the word basically means blending of finished wines to achieve a new wine - taken from the solera blending system used in Jerez, Spain, home of Sherry).

Ergo, one thing that makes it "one of a kind" is that is is a premium wine, but non-vintage.  Most premium wines are vintage-dated.

Plus the fact that it comes from one of the greatest wineries in California...
