For wine to be kosher, it does not matter what king of grape it is made from; nor does it matter what style of wine is produced; red or white, dry or sweet, still or sparkling. As long as the wine is produced by approved methods it is kosher.
Those methods essentially aim at guarding purity and cleanliness but include some strict religious requirements as well.
The wine must be held in containers deemed kosher, and all products associated with the winemaking must themselves be kosher.
Kosher wine are made all over the world, including Israel, the United States, France, Italy Spain, Portugal, Australia, Argentina, Chile, and South Africa.
The most significant states for the production of kosher wine in the United States are California and New York, where there are wineries and vineyards exclusively devoted to the production of kosher wine.
