S3x (S three times - small, sweet, sips) is a Botrytis late harvest wine from the Russian River Valley. This rare wine is made when a natural mold called botrytis cinerea "noble rot" infects the grape clusters in the vineyard. The botrytis makes the grape shrivel up as the water evaporates through the weakened skin resulting in an intensely sweet and concentrated juice. In Germany, this style of wine is designated as a Trockenbeerenauslese.
