Tempranillo more acidic wine. Tempranillo is the major component of the typical Rioja blends and constitutes 90-100% of Ribera del Duero wines. In Australia, Tempranillo is blended with Grenache and Shiraz, also known as Syrah. In Portugal, where it is known as "Tinta Roriz", it is a major grape in the production of some Port wines. Tempranillo is native to northern Spain and widely cultivated as far south as La Mancha. The two major regions that grow Tempranillo are Rioja, in north central Spain, and Ribera del Duero, which lies a little farther to the south. Substantial quantities are also grown
Arithmetic of abelian varieties Arithmetic of abelian varieties In mathematics, the arithmetic of abelian varieties is the study of the number theory of an abelian variety, or family of those. It goes back to the studies of Pierre de Fermat on what are now recognized as elliptic curves; and has become a very substantial area both in terms of results and conjectures. Most of these can be posed for an abelian variety "A" over a number field "K"; or more generally (for global fields or more general finitely-generated rings or fields). There is some tension here between concepts: "integer point" belongs in a sense
