Origin & Breeding History: 'Wurtwinning' originated from a cross pollination between the variety 'Honeycrisp' as the female parent and the variety 'SW 159' as the male parent. The cross was conducted at Elst, the Netherlands in 2004. The new variety 'Wurtwinning' was selected in 2010, in the Netherlands based on the quality of the fruit and resistance to scab. Asexual reproduction by graft wood was initiated in the spring of 2012.

The trial was conducted by the Bundessortenamt, at the Prüfstelle Wurzen Testing Station in Germany, from 2021 to 2022.
