Organic farming. Kulcsár is a single vineyard at the foot of a volcano where a large layer of lava flowed over. After millions of years of erosion, it’s extremely nutrient poor (little to no loam or humus), always gives a high extract, and forces the roots to go deep. Planted 45 years ago, it was so rocky (tons of rhyolite) that the local wine council extracted stones to help build a local road. Aromatic, which is typical for Hárslevelű, this is like drinking out of a quartz bowl with a chalk rim.
