The Solaris is a white grape variety developed in 1975 by the Weinbau Institute in Freiburg known as FR 240-75. She originated from the intersection of Merzling and Geisenheim 6493. This makes it a far-reaching relative of Riesling and Pinot gris. Because of all the cross, the grape has not completely remained a pure vitis vinifera, which makes it part of the hybrid varieties. The name Solaris is derived from “solar" the sun, because of its strength and early summer maturity.
In cooler wine-growing regions, such as Sweden , England and the Netherlands , the grape still gives high sugar and low acidity levels. An Oechsle content of around 100 degrees is regularly present. It is also resistant to fungi. Her soft skin makes it more susceptible to rot.
Although the grape can be used for dessert wines, it is very suitable for vinification of a more solid dry wine. The bouquet is flowery and often shows a whip of honey. The Solaris can be made from cépage wines, but it is also mixed with other grapes.
Because the Solaris has such favorable properties, it is also used to create new grape varieties.
