Sourced mainly from single vineyards in Westhofen (Benn and Kirchspiel), where grapevines thrive in clayey marl soils and limestone deposits. There are layers of limestone meandering through the substrate, channeling water and ensuring the plants have enough to drink even in the hottest parts of summer. The smallest vineyard in Westhofen, Benn is a monopole that has been in the Wechsler family for generations. These limestone rich soils are planted with 50-year old vines. Kirschspiel, a Grand Cru vineyard, is southern facing with a steep 30° gradient.
