The limited edition “Miljenko’s Selections” wines from Grgich Hills Estate are named for the winery’s co-founder and longtime winemaker 2014-ESS-FRONT-WITHOUT-ALCMiljenko “Mike” Grgich, and the label is a fitting tribute to this Napa Valley pioneer. (Present winemaker is Ivo Jeramaz.) Our Wine of the Day is the superb Grgich Hills Miljenko’s Selection Essence Sauvignon Blanc 2015, Napa Valley, a sauvignon blanc of riveting purity and intensity. The wine fermented with natural yeasts and aged nine months in large oak casks, so any wood influence is subtle, almost subliminal. The color is pale straw-gold; aromas of lime peel, lemongrass and gooseberry are heightened by notes of jasmine and lilac and a kind of sunny, leafy fig suggestion. The texture is both soft and talc-like and boldly crisp with assertive acidity; flavors take on a wisp of stone-fruit rounded by a tangerine edge, all finishing with grapefruit rind, seashell and limestone scintillation. The energy and elegance of this sauvignon blanc cannot be overstated, nor can its poignant, piercing minerality or its lovely sense of presence; it is one of the most sheerly beautiful examples of the grape I have encountered. 13.5 percent alcohol. Production was 646 cases. Drink now through 20 to ’22. Exceptional. About $55.

A sample for review. The label image is one vintage behind; 2015 has not made it onto the winery’s website.
