THIS HISTORY OF ZINFANDEL HAS BEEN ABOUT THIRTY YEARS IN THE making. Along the way I have profited continually from the advice, the hints, the practical assistance, and the good will of numerous individuals. Often the assistance has been the understandable consequence of institutional relationships. And there have been scores of people who just wanted to help.
Chief among the latter has been Professor Thomas Pinney of Pomona College. He has labored through every word of this work in draft and has left me and other wine lovers in his debt. As I have written of his previous help, “How could I hope to have had a better advisor than an English professor who is also an expert on wine history?”
John McGrew, formerly of the U. S. Department of Agriculture, set me straight on the history of eastern American viticulture. He is the final authority on that subject. And he introduced me to the wonderful viticultural collections at the National Agricultural Library in Beltsville, Maryland. There the staff provided my wife and me with a week's happy labor.
In Boston the staff of the Massachusetts Horticultural Society and the Boston Public Library helped make my research on early New England viticulture possible.
