100% Lagrein. Nusserhof makes three different Lagreins, this Riserva bottling being the main one, from this 600-year-old native variety.  The vines range from 20 to 90 years old and are wire-trained in Guyot and Casarsa; they are farmed organically and harvested by hand. The Lagrein is destemmed, fermented with native yeasts and macerated for four weeks. The wine is aged in French oak botti for two years, followed by at least two years in bottle before release (far exceeding the DOC requirement of a minimum of 3 years' aging for riserva wines).
