Italian white winemaking has improved greatly in the past decade or so, with producers paying more attention to appropriate soil types and climate, vineyard practices and methods in the winery. Not that seas of nondescript white wines from overcropped vineyards in areas that are too widespread don’t make it to our shores, but the wines under review today are not only delightful but encouraging signs of integrity and authenticity. The first is from Piedmont, the second from Sicily; both were made in stainless steel and see not a whiff of oak. One of the notable aspects of these wines is that they employ grapes that we don’t often — or actually never — see; again this reliance on indigenous fruit is a reflection of a desire to honor place and tradition. These wines were samples for review.

We drink gallons of Vietti’s Roero Arneis by the glass at the Italian restaurant we frequent. It’s great with salads, grilled vegetables, grilled octopus and sardines. The grape is arneis; the region in Piedmont is Roero, part of the Cuneo district. For 2012, this wine offers a very pale straw-gold color; yes, it’s clean as a whistle and fresh as a daisy, but it develops layers of nuance that focus on orange rind and lime peel with a touch of candied grapefruit before opening into a panoply of lemon effects that in turn call up spiced tea, lemongrass and limestone. Acidity is keen and steely; the texture is supple and lithe, sort of winsomely sinuous, and it all goes down very easily indeed. It’s as enticing and charming as it sounds. 13.5 percent alcohol. Drink through 2014. Excellent. About $23.

The Regaleali Bianco 2012, Sicilia, is a blend of 36 percent grecanico grapes, 34 percent catarratto, 20 percent inzolia and 10 percent chardonnay. The grapes derive from a vineyard planted in 1957 on the Regaleali estate owned by Count Tasca d’Almerita. The color is pale straw-gold; this is as spanking fresh as a sea-breeze, blown with brine and salt-marsh earthiness and highlighted by notes of apple and baked pear, peach and tangerine peel with hints of cloves and grapefruit. Chiming acidity keeps the wine electrically charged, while scintillating limestone minerality adds depth to the delightful citrus and stone-fruit flavors. The whole effect is bracing, saline and savory, with a tinge of almond-skin bitterness of the finish. 12 percent alcohol. Drink through 2014. Very Good+. About $15, a Terrific Value.
