Wine of the Week: 2009 Domaine de la Charmoise ‘M. de Marionnet’ Touraine Sauvignon Blanc

Sauvignon Blanc from the Loire Valley has a special character — minerally, lean, focused. At Domaine de la Charmoise in the Touraine, grapes from 40-year-old vines go into the signature Sauvignon Blanc “M. de Marionnet.� I love the notes of citrus and chalk coupled with a tart acidity and lingering finish.

A perfect warm weather wine, it’s great with chilled shellfish, Dungeness crab, steamed mussels and grilled fish. Keep an eye out for proprietor Henry Marionnet’s Vinifera wines too, made from grapes from ungrafted vines.
