List of grape varieties

Dunkelfelder is a red grape variety . It is a cross between Madeleine Angevine x Dye Grape ( Teinturier du Cher ). The original information provided by the breeder that it was a cross between Blauer Portugieser and Färbertraube has since been refuted by DNA analysis. The new breed took place at the beginning of the 20th century by Gustav Adolf Frölich (1847–1912) from Edenkoben , but the variety spanned a shadowy existence in the breeding institutions for years.

It was given the name Dunkelfelder at the Geisenheim research institute as an allusion to the dark color of the juice. The grape variety thus belongs to the dye grape family . Plant variety protection has existed for the dark fields since 1980 .

The variety is often used as a cover wine in cuvées to enhance the color . Small stocks are also registered in Switzerland and the south of England.

Ampelographic varietal characteristics

In ampelography , the habitus is described as follows:

  • The shoot tip is open. It is densely woolly to tomentose hair.
  • The medium-sized leaves are five-lobed and indented to a medium depth. The stalk bay is V-shaped, open to touching. The blade is roughly serrated. The leaf surface (also called blade) is dark green in color. From the month of August, the leaf turns red and blotchy.
  • The cone-shaped grape is medium-sized, broad and medium-density berries. The slightly oval berries are blue-black in color. The berry is scented and has a neutral to slightly sour taste.

The dark fields can be harvested approx. 15-20 days after the Gutedel . The grape variety sprouts very early and is therefore sensitive to possible late spring frosts. Due to its good wood maturity, the winter frost hardness of the Dunkelfelder is sufficiently good and thus better than that of the Blauer Portugieser.

The vines are not very demanding in terms of soil conditions and produce good yields. Darkfields is sensitive to frost, drought and fungal diseases such as downy mildew . In addition, it tends to rot very quickly. In the event of an infection with the stickworm- transmitted brushwood disease , the crop failure is greater than the average compared to other grape varieties.

The wine from Dunkelfelder has a black-red color and a full-bodied and lasting taste. The level of acidity (→ acidity (wine) ) is rather moderate, which many consumers benefit from (acid sensitivity). With the high dye content, there is also a high proportion of tannins (see also the article Phenols in Wine ). Due to its characteristics, it is also suitable for aging in oak barrels ( barrique ). Rosé wines can be produced with short maceration .

Distribution in Germany

In Germany in 2007, 362 hectares (= 0.4% of the German vineyard area) were planted with the dark fields grape variety. The area has been constant for several years. In 2006, 372 hectares of cultivated area were planted, after 280 hectares were surveyed in 1999.

The vineyards in Germany were distributed among the individual growing areas in 2007 as follows:
