Viticulture and winemaking are the most important fields of Georgia's agriculture. Over 450 species of local vine are bred in Georgia, and the country is considered as one of the oldest places of producing top-quality wines in the world. Russia was traditionally the biggest export market for Georgian wine. This, however, changed in 2006, when Russia banned imports of wine and mineral water from Georgia, preceded by statements of Georgian governmental officials about low quality requirements of the Russian market. Since then Georgian wine producers have struggled to maintain output and break into new markets.
