France, Italy and Spain, the world's largest wine producers, are holding the first wine fair in Vietnam this month to familiarize the "growing market" with their top vineyards. “Why went Vietnam? Because we feel that it is time, when the market is growing, and before it’s too late to explain how to drink wine and let them know why they drink our quality and traditional wine,” Jean-Louis Poli, Commercial Counselor of the French Embassy in Vietnam, told a press briefing at French Consulate in Ho Chi Minh City Thursday .
