Country: United StatesAmerican wine has been produced for over 300 years. Today, wine production is undertaken in all fifty states, with California producing 89 percent of all US wine. The United States is the fourth-largest wine producing country in the world after France, Italy, and Spain. With more than 1,100,000 acres (4,500 km2) under vine, the United States is the sixth-most planted country in the world after France, Italy, Spain, China and Turkey.
Zinfandel (also known as Primitivo) is a variety of black-skinned wine grape. DNA fingerprinting has revealed that it is genetically equivalent to the Croatian grape Crljenac, as well as to the Primitivo variety traditionally grown in Apulia (the "heel" of Italy), where it was introduced in the 18th century. The grape found its way to the United States in the mid-19th century, where it became known by variations of the name "Zinfandel". The grapes typically produce a robust red wine. The grape's high sugar content can be fermented into levels of alcohol exceeding 15 percent. The taste of the red wine depends on the ripeness of the grapes from which it is made. Red berry fruit flavors like raspberry predominate in wines from cooler areas, whereas blackberry, anise and pepper notes are more common in wines made in warmer areas and in wines made from the earlier-ripening Primitivo clone.
