Grape

Johanniter

Johanniter is a white grape bred at Freiburg for improved resistance to fungal diseases. It often combines a restrained fruit aroma with lively acidity. Its use in the Netherlands shows how German breeding work has become part of a developing northern European wine culture.

Breeding and vineyard behaviour

The State Viticultural Institute in Freiburg identifies Riesling as one parent, with Seyve Villard 12-481, Pinot Gris, and Chasselas in the other side of its pedigree.1. Staatliches Weinbauinstitut Freiburg, “Johanniter,” cultivar profile. Its profile describes upright growth, compact bunches, and moderate resistance to downy mildew, powdery mildew, and botrytis. That last distinction matters: the word resistant describes a reduction in susceptibility, with different results for different pathogens.

The institute describes peach-like fruit and a style that can recall Riesling. The comparison is useful for aroma and acidity, while harvest timing and fermentation still determine the individual wine's balance.

A Dutch example

Avendorp's Johanniter 2023 is documented as entirely varietal. The same West Frisian producer uses Johanniter in its sparkling Parel wines; the 2025 version brings together fruit from Avendorp and nearby Saalhof.2. Avendorp, “Johanniter 2023,” including the associated Parel descriptions, accessed 22 September 2026. These bottlings provide specific examples of both still and sparkling uses.

For a sparkling base, acidity has a different role from that in a still white: it must support the finished wine after the choices involved in making and finishing the sparkling wine. A grape's regional usefulness can therefore extend beyond one familiar style.
