Valais 2011, Fendant de Sierre, Domaines Rouvinez ($19.95, 11598538)
100% Chasselas. Vinified in tanks. Matured on the fine lees. 12% ABV.
White flowers, flint, faint lemon. Light- to medium-bodied. Slight residual sugar and spritziness at first. Clean and bright if a bit hollow on the mid-palate. A fresh mint note scents the dry, bitter-edged finish. (Buy again? Maybe.)

Neuchâtel 2011, Auvernier, Domaine de Montmollin ($20.95, 00721233)
100% Chasselas from vineyards located near the village of Auvernier. No winemaking information found. 11.5% ABV.
Similar to the Fendant though showing some pear and a hint of ash. Dry and just a little spritzy. The pure fruit and bright acidity intertwine with bitter quartz on the finish. Simple but fresh and lovely. (Buy again? Yes.)

La Côte 2010, Doral, Expression, Uvavins-Cave de la Côte ($23.25, 11885609)
100% Doral, a relatively new cross between Chardonnay and Chasselas. Uvavins is a large growers’ cooperative. No winemaking information found. 12.9% ABV.
Slightly oxidized sour apple. Clean and rich with ripe fruit, just a hint of sugar, soft acidity, faint chalky minerals, a honeyed note and some hay and straw on the solid finish. (Buy again? Sure.)

Valais 2011, Petite Arvine, Château Lichten/Domaines Rouvinez ($34.75, 10867599)
100% Petite Arvine from 20-year-old vines. Vinified in tanks. Prevented from undergoing malolactic fermentation. Matured on the fine lees. 13.5% ABV.
Quartz, lemon, mountain air, faint apricot, rhubarb and apple. Smooth and rich on entry, with a winey, almost creamy texture. Somehow both present and ephemeral, the fruit is carried over smooth stones on a gurgling stream of acidity. A faint bitterness surfaces on the long, lightly sour and saline finish. Such poise and balance. Unique and delicious. (Buy again? Done!)
