They've been making wine on Samos for thousands of years, and they're specialists. Huge swathes of the island are planted with just one variety - Muscat Blanc à Petits Grains. And almost all of that is controlled by one producer, the co-operative. They make a bewildering array of wines. The best is Nectar. It's made by sun-drying grapes from selected vineyards to give a very sweet wine. This is aged in oak for at least six years, but sometimes far longer. It is a world-class sweet wine, amber in colour, with loads of complexity, and great sweetness matched by bracing acidity.
