From Vom Boden: "The Kupp GG is normally the most “complete” of all the GGs; it is a wine that shows both fruit and depth (like Feils) as well as a dense mineral core of slate and salt (like Schonfels). It is perhaps the most elegant of the wines, with fine layers and a suave, polished finesse. Kupp tends to have more structure than Feils, so it normally needs a few years in the bottle to begin to show. It also benefits from a serious decant."
