Long ago, sweetness in any form was far rarer than today, and it was prized thusly. In our era of ubiquitous corn syrup, junk food, and soda, it is difficult to imagine a world in which sugar was special, and the overall difficulty in selling sweet wines across all markets testifies to that. Still, sweetness in wine—real wine whose sweetness has not been coerced—remains one of nature’s rare gifts.
