Let’s travel back to Franciacorta in Lombardy for a fine example of the craftsmanship that can occur there. Our model is the Antica Fratta Essence Brut 2007, a blend of 90 percent chardonnay and 10 percent pinot noir grapes that spent three years en tirage, to use the French term meaning resting on the lees in bottle, and another six months in the cellar after disgorgement, the rather unpleasant word for the process of releasing the accumulated yeast from the bottle. Anyway, the color is pale straw-gold, and the bubbles form a miniature tempest of persistent effervescence. Not quite a true blanc de blancs, because of the 10 percent pinot noir, nonetheless Antica Fratta Essence Brut 2007 is light, delicate and supremely elegant, a highly refined sparkling wine that still does not stint on ripeness and flavor. Notes of roasted lemon and spiced pear are highlighted by lime peel and a hint of fresh bread, while a few moments in the glass bring in elements of limestone, flint and grapefruit rind. The texture is perfectly balanced between ample expansiveness and clean, bright acidity, lending the Antica Fratta Essence Brut 2007 a welcome sense of vibrancy and tension, all resolved in a lacy spice-and-mineral-infused finish. 13 percent alcohol. A favorite in our house. Drink through 2015 to ’17. Excellent. About $32.
