The commission’s “Year of Riesling” declaration for this year focuses on a wine grape variety grown in the state since the 1970s. Riesling wines are to be highlighted this year including on International Riesling Day March 13, at the Savor Idaho industry and community gathering to be held all day June 7 at Idaho Botanical Garden in east Boise, and throughout June — which is Idaho Wine and Cider Month.
