(Gruh-NOSH Blonk) is the white-berried equivalent of Grenache Noir, and, like its red variant, is drought-resistant, vigorous, and easy to graft. The varietal originated in Spain and still plays a role in the wines of Rioja and Navarre. From Spain, it spread to France where it has thrived in the vineyards of the Rhône valley and Châteauneuf-du-Pape. It is the fourth most commonly planted white grape varietal in France, comprising over 37,000 acres in Roussillon alone. Its high-sugar, high-acid, straw-colored bunches produce wines that are high in alcohol, with green apple flavors and aromas. Although it can stand confidently on its own, its crispness and long finish make it a tremendous blending component.
