Few countries, if any, can compete with Portugal’s treasure of varietal diversity and the territorial diversity that sustains it. Certainly, the production of single variety wines is part of the process of understanding that diversity. But the real asset, the value in that varietal diversity, is the complexity of the blend. American wine drinkers are more likely to find consistency buying regional blends than varietal wines from range of different Portuguese regions. Top quality regional blends as well as entertaining, creative riffs on these traditional wines will educate consumers and serve to build brand Portugal. My advice: Sustain the priceless diversity in your vineyards and use it to produce the refined and elegant wines that have made Portugal famous for centuries. The 21st century will be better for it.
