The Grosses Gewächs Réserve wines are selectively harvested from the finest parcels of very old, ungrafted vines. They are naturally fermented in the same way as the GGs but stay for 24 months on the full lees in traditional Fuder casks. They are then held in bottle for a further 24 months before release. This extended maturation brings an extra dimension of finesse and balance to our wines. Erdener Prälat is perhaps the greatest vineyard in the Mosel region. It benefits from its 45° slope with perfect southern exposure, red slate soil and proximity to the river. All these factors, combined with its position below huge, heat-retaining cliffs, explain why Dr. Loosen never harvests anything less than Auslese ripeness from this site.
