Roesler is a crossing of Zweigelt and an unnamed variety that has extreme cold hardiness, a resistance to mildew, and deeply colored fruit. It is blended with Blaufrankisch for this cuvée. The vines are 35 years old and are planted in gravel. The grapes are destemmed and allowed to ferment in 500L, 1000L, and 1500L neutral oak barrels. Élevage is done in 500L barrels for 8 months before the wine is bottled, unfined and unfiltered.
