With seven wines tied for first place, this year's 10-year cabernet sauvignon retrospective tasting created its own version of “Bottle Shock.”The final tally was unprecedented in the Press Democrat's 16 years of conducting the tasting. The retrospective tasting has become a tradition because the 10-year mark is a perfect time to gauge the progress of aging California cabernet sauvignons (and Bordeaux red blends). Those with good balance and a solid structure upon release are expected to show well after 10 years, emulating the great wines of Bordeaux that can last decades in the bottle.
