riesling 2017 From now 24 year old vines grown on gray slate, the soils are rejuvenated every five years with fresh compost; the grapes are handpicked around October 15 and sorted selectively. The grapes are then moved to the press where they are pressed very lightly and slowly. Fermentation lasts for nine weeks in stainless steel (1000L), resting on lees until January.
