A.k.a. Cencibel. Just about synonymous with Spanish wine, the red Tempranillo grape has now fully won over the hearts and minds of critics and amateur oenophiles all over the world. The best bottles are powerful and ageworthy, and are beginning to fetch prices you'd never have expected from Spanish wines just a few years ago. Tempranillo is often used in blends with Bordeaux grapes such as Cabernet Sauvignon and Merlot, and has lately been grown with considerable success outside of Spain, in regions like Portugal, Argentina, and California.
