The Alsatian Johann Michael Ortlieb (1730-1807) was an industrialist, farmer, winemaker and innkeeper and published in 1789 a book in which he improved the viticulture and the cultivation of white grape Knipperlé (Little Räuschling) propagated, which was later also known as Ortlieber after him. king Frederick II the Great (1712-1786) tested the variety on the "Royal Vineyard" in the Marche Brandenburg planting. In his work, Ortlieb recommends, among other things, not planting vines in the plain, and that the vines should be peeled off 14 days after harvest blossom to expose them to the sun. For not unselfish purpose, he dedicated the book King Louis XVI. (1754-1793).
