The book "Foundations of American Grape Culture" by Dr. T.V. Munson is an excellent reference on heirloom grape varieties, especially in North America. Reproductions of the book published about 1900 are available from the Munson Memorial Vineyard (Link The T.V. Munson Memorial Vinyard and Viticulture - Enology Center.)
Dr. Munson in Texas and a colleague in Missouri developed root stocks that saved the French vineyards in about 1900. Lots of great information from Dr. Munson and the 100+ grade varieties he developed at his vineyard in Denison, Texas.
