The "Swedish grape" Solaris is a medium-growing green grape created by the state wine institute in Freiburg, Germany by crossing the varieties Merzling and GM6493. It is a so-called PIWI plant (pilzwiderstandsfähig), meaning a grape that is characterized by its resistance to diseases and powdery mildew. The clusters are medium-sized and the plants are rich-bearing, the leaves are large and bright green. The wines can vary greatly in aroma from aromatic tones to ripe yellow apples and honey tones, depending on the place of cultivation and winemaking philosophy. The taste is strong and concentrated, usually with a good body. Many Solaris wines also have a high alcohol content of 13-14%.
