Johanniter is a white grape variety. The grape was bred by Johannes Zimmermann of the wine-growing institute in Freiburg in 1968 as a mold-resistant. It is the result of a combination between Riesling, Seyve-villard, Ruländer, and Gutedel.
The grape is named after the breeder, a scientist at the Freiburger Institute who had a good insight of the mold-resistant grape varieties. Harvest time is somewhat earlier in the year.
To obtain high quality wine from this grape, it is necessary to make a substantial cut.
The wine made from the Johanniter can be fruity such as Riesling and Pinot Gris wines. This grape is mainly found in German wine-growing . About 60 ha (2007). In Switzerland 16 ha (2013). The Dutch viticulture also knows the Johanniter.
