Dunkelfelder sprouts very early and is therefore sensitive to possible late spring frosts. Due to its good wood maturity, the Dunkelfelder's winter frost hardiness is sufficiently good and therefore better than that of the Blauer Portugieser.

The vines are not very demanding when it comes to soil conditions and produce good yields. Dunkelfelder is sensitive to frost, drought and fungal diseases such as downy mildew.

Origin:

After the name purple was rejected by the Federal Plant Variety Office, it was decided to give the new grape variety the name Dunkelfelder. The breeding by Gustav Adolf Froelichs (1847-1912) from Edenkoben was created from the Madeleine angevine and Teinturier (Färbertraube) grape variety.
