Thanks to Texan viticulturist Thomas Volney Munson, you should probably think of Texas when you think of that French wine you're drinking. During an agricultural crisis in France in the late 1800's, his tough grafted Texan vines saved the industry from total collapse. And many of the vines in Europe are still growing strong from that rootstock today. This week's episode tells this story of T.V. Munson and how his obsession with grape vines saved old world wine.
