Feldspar, quartz & mica

... is the mineral composition of volcanic rhyolite—also known as quartz porphyry—which characterizes the soil in which this Chardonnay grows. Daniel Wagner relies on selective, early hand-harvesting, spontaneous fermentation with hand-destemmed grapes, 100% oak barrel aging, and 18 months of lees aging. His new organically produced Chardonnay is bottled unfiltered and minimally sulfured. Purist, mineral, with a firm yet creamy acidity.
