Following the example of neighboring Chile, the Argentine wine industry started to more aggressively focus on the export market—particularly the lucrative British and American markets. The presence of Flying winemakers from France, California and Australia brought modern technical know-how for viticultural and winemaking techniques such as yield control, temperature control fermentation and the use of new oak barrels. By the end of the 1990s, Argentina was exporting more 3.3 million gallons (12.5 million liters) to the United States with exports to the UK also strong.
