The third generation of the white “Fledermaus” has been harvested in September 2017 and bottled in March 2018. It consists of about 70% Müller-Thurgau and 30% Silvaner. The whole Müller-Thurgau clusters were pressed, the juice sedimented, racked and aged on the full lees in stainless steel. The Silvaner grapes were destemmed, sitting on the skins for a night, pressed and fermented in big oak barrels (one old one new).
