This wine, according to the winery's fact sheet, is named for the "bright and sunny spirit of Anna Moser, daughter of Laurenz V Moser and great granddaughter of Laurenz III, who was one of the first to establish Gruner in this region." And the wine certainly reflects the sunny climate of the Kremstal region of Austria (northeast of Vienna) with its alternating warm and cool breezes.
I'm becoming enamored of Gruner because it goes so well with so many dishes and is a welcome alternative to the Chardonnay/Sauvignon Blanc axis. This was my first try of Sunny, and I promptly went back for more. Brilliant, light color. Fresh, citrus-tinged aromas that burst from the glass. Flowers, green herbs, and peppery spice. Very fresh, almost spritzy, on the palate. Sunny has a little bit of residual sugar (4 g/liter) that adds some fatness and body to the mid-palate but hardly gets noticed against the brisk acidity.
