Bronner

General: The Bronner variety belongs to the repertoire of the Viticultural Institute in Freiburg. It originates from Norbert Becker's breeding work and succeeded in 1975 as a cross between Merzling and "Gm 6494". The variety was named in honour of the Baden wine pioneer and pharmacist Johann Philipp Bronner (1792 to 1864).
Cluster: The medium-sized grapes are often shouldered and medium to heavily packed. The grape weight is not infrequently around 280-300 grams.
Resistance:

Peronospora +++

Oidium +++

Botrytis +++

Wine: The wines of the Bronner are more of the neutral types. They show similarities to Pinot Blancs with aromas of pear, local apricot and quince with mild acidity. Good qualities are characterised by high ripeness and a moderate yield level.
Cultivation: The variety is very similar to Pinot Blanc in terms of site requirements. However, sites with a high risk of drought should be avoided. Bronner buds, flowers and is ready for harvesting about 7 to 10 days later than Burgundy. Despite relatively early flowering, the variety ripens relatively late. Due to its strong growth, wider distances between the vines and, for example, two short arches in the cutting should be chosen in order to make full use of the vine's vegetative potential. Due to the berry weights and the compact cluster structure, interventions in the yield potential are advantageous.
