Diamante Semi Dulce is a semi-sweet white wine from the D.O.Ca Rioja appellation in Spain, produced by Bodegas Franco-Españolas. First introduced in 1981 as the pioneering semi-sweet white wine from La Rioja, it is crafted primarily from the Viura grape with small proportions of Malvasía. The wine carries approximately 11.5% alcohol by volume.

On the palate, Diamante is light and refreshing with aromas of lemon curd, honey, and apricot. Its gentle sweetness is balanced by bright acidity, giving it a fresh, fruity character that makes it approachable and versatile. Each bottle contains 750ml. Costco sells it as a case of 12 bottles.

This wine pairs well with appetizers, seafood, shellfish, rice dishes, cold plates, and desserts. Bodegas Franco-Españolas was founded in 1890 as a Franco-Spanish partnership and remains one of Rioja's historic producers.
