The 1970 and the 1971 Ridge Occidental Zins. I tasted them close to 10 years ago but had the chance to taste them within a week of each other, just by coincidence.
Nice wines, still drinking decently but like a light styled claret.
Very cool to try but 30 year old zins are probably not the best thing to be going for.
Operative term: "claret style". I recall two visits to Ridge in the early 1980s and it was almost odd to see a label with an alcohol over 13-13.5%. The Paso Zin was an exception.
