Hungary’s Tokaji Aszu, Portugal’s Port, Spain’s Sherry, France’s Sauternes, Germany’s Trockenbeerenauslese, and South Africa’s Vin de Constance were all once regarded as the greatest wines in the world and were readily drunk, as were sweet wines in general. Historically, the popularity of sweet wines was due not only to their profound taste, but also because, before the modern era of food manufacturing and trade, sweet foods were scarce. Sweet wine, on the other hand, was readily available and could be stored and drunk any time of year.
