Here are notes on two terrific French white wines we took to dinner at Restaurant Iris in Memphis. Great meal, too, and thanks to our generous friend Allison Jacob, editor and publisher of CorkIt! magazine, for bringing the splendid Eagles Trace Estate Cabernet Sauvignon 2005, Napa Valley.
Chateau La Louvière, fortuitously located in the Bordeaux commune of Pessac-Léognan, traces its origins to the year 1476, when the first vines were planted, though for the modern period the important date is 1965, when André Lurton acquired the property and completely transformed it. The exquisite Neo-Classical style chateau, dating from the late 18th Century, is listed in the official Roster of Historic Properties. La Louvière produces about 12,500 cases of red wine and about 4,160 cases of white wine annually, as well as red and white wines under the second label, L de La Louvière. The cepage for the blanc is 85 percent sauvignon blanc and 15 percent semillon. The wine ages typically for 12 months in a combination of oak barrels, 30 to 50 percent new, depending on the year.

Chateau La Louvière 2009, Pessac-Léognan, is about exactly what one wants a sauvignon blanc-based wine to be, or at least it thoroughly convinces you that that’s the case when you’re drinking it. (Pessac-Léognan was separated from Graves in 1987 and granted its own AOC status; most of the finest chateaus in this former area of Graves were included in the new appellation.) The wine opens with a burst of roasted lemon and a snap of flint, quickly joined by notes of grapefruit and jasmine, lemon curd and acacia; a few minutes in the glass unfold hints of a sunny, leafy, slightly herbal element and a touch of fig. This is so clean and fresh, utterly youthful, shot through with bright, almost joyful acidity — well, the liveliness makes you feel that happy — and bolstered by a keen limestone edge; these factors do not prevent the wine from exhibiting lovely resonance and vibrancy and a texture that’s close to talc-like while balanced by intense crispness and a supple, lacy spiced oak structure. So complete, pure and intense, yet balletic and light on its feet. Drink through 2015 to ’17. Excellent. Average price in the U.S. is $42, but I sure did pay $50 right here in good ol’ Memphis, Tennessee.

The William Fevre Bougros Grand Cru Chablis 2006 is the best white wine I have tasted in a blue moon; it’s the kind of wine to which one says, “O.K., I place myself in your hands. Do with me what you will.” This is an astonishing revelation of the purity, intensity and authority of the chardonnay grape, and while the wine does undergo oak aging — a controversial position in Chablis where many great wines are made in stainless steel — the amount of new oak barrels at the domaine was reduced in 1998 when the Champagne house of Henriot acquired the property. The color is light straw-gold with a slight green tint; the knock-out bouquet weaves tremendous elements of limestone and flint with lemon balm and lemon curd, fleshy and lightly spiced stone-fruit and an earthy undercurrent — just a hint — of sauteed mushrooms. The wine is indubitably rich, almost lavish, yet it’s taut with crystalline acidity and scintillating limestone elements and exhibits really amazing energy and dynamic qualities; call it charisma, because this is one freakin’ gorgeous wine! And yet, for all its star-quality, the William Fevre Bougros Grand Cru Chablis 2006 is built on layers of subtlety and nuance, and ultimately it allows its elegant character to dominate its power. At just over five years old, this is drinking beautifully and should continue to drink beautifully through 2016 to ’18, as long as it’s well-stored. Exceptional. I paid $70.
