What to Expect
Expect a journey through the versatile world of Riesling from the Rita & Rudolf Trosßen brand. Origin unknown, but this wine likely shares the grape's ability to produce wines ranging from bone-dry and crisp to intensely sweet, with alcohol levels and residual sugar varying widely as it does in other regions like the Pacific Northwest, New York, and Michigan.
