9. Quivira Dry Creek Valley Zinfandel  (13.5%) '85: Med.dark color; fragrant perfumed talc Am.oaked spicy some raspberry Zin nose; tart bit lean metallic appely light raspberry oaked bit thin flavor; med.short dried out cedary oaked tannic very light raspberry finish; drying out & dying on the palate but nice nose; this was Doug Nalle's last wine at Quivira.

Eberle Paso Robles Sauret Vineyard Zinfandel  (14.8%) '89: Med.light color; lovely lush fragrant strawberry/raspberry spicy light oaked nose; tart lush very spicy bright raspberry/strawberry light pencilly/oaked flavor; long bright spicy raspberry/strawberry light pencilly finish w/ light tannins; still loads of that bright raspberry/strawberry fruit but ready to drink; Gary's first Zin since his EstrellaRiver days; this has always been such a bright spicy very nice drinking Zin, not a big powerhouse of a wine. 
12. Storrs Ben Lomand Mountain Beauregard Ranch Zinfandel (13.7%) '91: Dark color; very  strong dusty/walnutty smokey/pungent/pencilly oaked mtn Zin light raspberry nose; rich pungent mtn Zin dusty/walnutty complex some raspberry flavor; very long dusty/walnutty complex SantaCrzMtn Zin light blackberry finish w/ light tannins; a very complex interesting Zin atypical of Calif Zin but rather typical of SCM Zins; like some of the Ridge Jimsomare/MonteBello Zins of old; this has been a rather hard/rustic Zin & starting to show some real complexity; very well-done Zin.
13. Sea Ridge Occidental Vineyards Zinfandel  (13.5%) '91: Black color; intense overripe blackberry some oaked nose; very tart intense blackberry off-dry pungent licorice charred flavor; very long overripe off-dry tart blackberry/boysen- berry pencilly oaked dusty finish w/ ample tannins; will age for a long time if it's a good bottle; a dead ringer for the Ridge Occidental '70 (one of the greatest Zins ever made); lots of bottle varibility on this wine, some have been fizzy & doing a M-L in the bottle or refermenting; this is the best bottle by far. 

1. The DeerPark, the two Buehlers, the Santino were all stunning/mature Zins; the Eberle,the Storrs, the SeaRidge equally fine but younger wines. The others were pretty typical of old Zins.... interesting intellectual experiences but seldom exciting sensual pleasures (reminds me of a few... oh, that's a subject for another forum!). None were unpleasant, just some didn't thrill much.  So do Zinfandels age??? Do high-alcohol "monster" Zins age? The folklore is that a Zin must be "well-balanced" to age? So what does this data tell us?? Actually, not a whole lot. The Shafer, the ZD, the Quivira were nice "well- balanced" Zins in their youth. Gone gone gone now! The Buehlers and the DeerPark were big ripe huge Zins in their youth, monster Zins. Still with us and doing fine, thank you! The Montevinas were big ripe, loaded w/ lush Amador jammy fruit, not particularly alcoholic (but don't put much credance in the 14.5% & 15% levels on the label), bright zippy Zin in their youth. Dried out & gone now! The Eberle was always a brigt zippy all-in-the nose Zin when first released. Doing just fine. So it's going to take someone with a grander intellect than mine do make any sense out of this & come up with some gross generalities... so we don't have to do any thinking on our own!! Actually, this is pretty typical tasting of older Zins... some we expect to be doing fine... are dead; and some we expect to be dead... are doing fine. It's just a bigger crap-shoot w/ Zins than it is w/ Cabs.... but who'd stoop to drink those wines!!  :-) TomHill (heading home to take yet more data points!!)
