Hugh Eric Allan Johnson is an English journalist, author, editor, and expert on wine. He is considered the world's best-selling wine writer. A wine he tasted in 1964, a 1540 Steinwein from the German vineyard Würzburger Stein, is considered one of the oldest to have ever been tasted.

Würzburger Stein is a vineyard in the German wine region of Franconia that has been producing a style of wine, known as Steinwein since at least the 8th century. Located on a hill overlooking the Main river outside the city of Würzburg, the vineyard is responsible for what may have been the oldest wine ever tasted. In addition to being one of Germany's oldest winemaking sites, at 85 hectares, the vineyard is also one of Germany's largest individual plots.
