The US Alcohol and Tobacco Tax and Trade Bureau (TTB) subsequently discouraged the use of the term "Gamay Beaujolais" and ruled that, from 1997, it could only be used as a secondary designation on wines made from more than 75% Pinot noir or Valdiguié. Since April 2007, the term "Gamay Beaujolais" has been banned from labels in the United States. Gamay Beaujolais Gamay Beaujolais is a varietal designation for a Californian grape variety, an early
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
