Moldova's proximity to the Black Sea gives it a mild and sunny climate. The fertile soil supports wheat, corn, barley, tobacco, sugar beet, and soybeans. Beef and dairy cattle are raised, and beekeeping is widespread. Moldova's best-known product comes from its extensive and well-developed vineyards concentrated in the central and southern regions. In addition to world-class wine, Moldova produces liqueurs and sparkling wine. It is also known for its sunflower seeds, walnuts, apples, and other fruits. This makes the area ideal for agriculture and food processing, which accounts for about 40% of the country's GDP.
