The Republic of Georgia is home to the oldest winemaking tradition in the world, producing vintages unique in their variety and quality. But all that was nearly lost when the Soviet Union absorbed the country, collectivized the vineyards, and began imposing socialist practices that favored quantity and homogeneity over quality and diversity. Only now, three decades after the fall of the Soviet Union, is Georgia’s winemaking industry recovering from a nearly fatal blow. The Red Line explores life on an independent vineyard, the winemakers’ passion for their work, the beauty of their product, and the cultural importance of preserving a tradition that runs through the veins of every Georgian citizen.
