Schiller wine is a Rotling made by mixing white and red grapes in the must. The grapes have to be harvested from the same parcel in the vineyard and must meet the minimum Swiss QbA (Qualitätswein bestimmter Anbaugebiete) of the specified region to be marketed as a Schiller wine. Because of the color, Shiller wine is often called a rosé, but that’s not strictly correct.
A Rosé is made exclusively with red wine grapes. Shiller wine produced in Graubünden tends to have higher proportions of red wine grape, while in Valais it’s reversed with white grapes, usually, Fendant (Chasselas), having a higher percentage. Shiller wine is also made in St. Gallen.
