"Gunderloch's very best wines are from the Pettenthal (where the family owns 3.3 hectares) and the warm, wind-protected part of the Rothenberg (4.5 hectares). Gunderloch's dry "GG" Rieslings Rothenberg and Pettenthal belong to the very best I have tasted from Nackenheim and Nierstein this year." -Stephan Reinhardt, Wine Advocate
One of the three grand cru Rieslings made at Gunderloch (Hipping, Pettenthal, Rothenberg). The Pettenthal site has sandier soils and smaller rocks than Rothenberg with a deep topsoil. The wine is 100% aged in 600L neutral barrels, a welcome trend at this estate in the last few years. Indeed, this wine is a prime example of the new and exciting direction in which Johannes is taking this estate--more work in the vineyard and less in the cellar, natural fermentations, more relaxed character in the wines, lighter structures and more transparency overall. The 2018 is still knitting together, but the signature of the vineyard (ferrous red soil character, orange/tangerine aromas, and zesty, lifted character) are already there.
