Words like nervous, nervy and nervosity derive from the Latin nervosus, which means “sinewy.” “Nervous,” in English, once meant “vigorous” or “spirited,” but those denotations are considered archaic, and our sense of the terms now centers on excitability, unease and apprehension. I would vote for reviving the original or archaic meanings of nervy and nervosity — sinewy, vigorous, spirited — because they acutely summarize the qualities in some wines, particularly white wines, that feel unusually lively, immediately appealing and crystalline in their litheness and crisp vibrancy. Such a wine is the Domaine Mittnacht Freres Les Petits Grains Pinot Gris 2011, from Alsace. Man, this has nervosity in spades, as well as reservoirs 0f scintillating and resonant limestone and flint qualities and that irresistible tension between the tautness of bright acid and the lushness of ripe and spicy pear, yellow plum and peach skin flavors. The note of peach skin brings in a hint of spareness and slight bitterness, and there’s a touch of almond skin here that contributes a similar attribute. The bouquet offers notes of jasmine and honeysuckle and lemongrass, but mainly this is cool, elegant and — did I mention sinewy nervosity? 14 percent alcohol. We drank this with seared swordfish dressed with nothing but olive oil, lemon juice and Urfa pepper. Now through 2015 or (well-stored) ’16. Excellent. About $22.
