“Old World” refers to the areas considered to be the birthplace of wine grapes, mostly in Europe or the Middle East. Countries that belong to the Old World wine include France, Italy, Spain, Germany, Portugal, Austria, Greece, Israel, Georgia, Hungary and Lebanon. The “New World” generally refers to countries or regions that introduced wine grapes from foreign countries and began to produce wine later. Countries that belong to the New World wine include the United States, Australia, South Africa, Chile, Argentina, New Zealand and Japan. The taste of wine is mainly affected by different factors such as the winemaker, the style of the winery, the climate of the vineyard, and the soil. Due to the different terroir conditions between New World wine-producing countries and Old World wine-producing countries, the wines produced have their own styles. Old World wines generally have a milder taste, higher acidity, lower alcohol content, and more fruity aromas; New World wines generally have a riper fruit aroma, lower acidity, higher alcohol content, and richer fruit aromas. However, in the old world, there were many laws and rules, and the style would be relatively uniform; in the new world, due to looser laws and advanced brewing technology and equipment, more styles can be created.
