Question: Which wine country has avoided phylloxera damaging the vineyards?
Answer: Tricky. Phylloxera results from an insect feeding on the sap of grapevine roots thereby killing them. Probably the consensus answer would be Chile. However, there are many other wine producing regions that have been phylloxera-free so far. These include the historic Colares in Portugal on those sandy soils, isolated Tasmania and other parts of Australia (Barossa Valley), parts of Hungary, and those special slate soils for Riesling in the Mosel Germany. Has anyone researched this issue and come up with a definitive list?
