I have seen mash bills from the late 18th or early 19th century that state use rye or wheat as the second grain, so it is not anything new. The modern wheated bourbons though all come from a single line created by the Stitzel family before prohibition and became used by the Stitzel-Weller distillery after prohibition. Maker's Mark is included here because they did get the recipe and yeast for their whiskey from the Stitzel-Weller distillery.
