By far one of the most difficult topics to research was which grape varieties we would plant. We decided to divide the vineyard between red and white grapes although Bill's innately fine palate would have been happy with all Cabernet Sauvignon.
The wine world was really a hazy jumble of French and Italian names to me. I knew the well-known varieties such as Cabernet Sauvignon, Pinot Noir and Sauvignon Blanc and associated these wines with regal vineyards in Europe or California while Concord and Cayuga conjured up the chilly lake regions of North America. We still didn't know what varieties would grow in our region and in order to talk to someone local about it, we really had to be more knowledgeable about wine in general, so we really had to start our research with the basics of wine grape evolution.
At the risk of making this post very dry, I think it is necessary to quickly outline the grapevine family tree. Remember Kingdom, Phylum, Class, Order, Genus, Species? Grade school biology? Well all grape vines are of the genus Vitis. Come on, this actually gets interesting, with a French/American anti wine snob happy ending!
In the beginning, there were two major grape species at the top of the chart. The Eurasian species Vitis vinifera and the American species Vitis labrusca. Vitus Vinifera grapes have been used for centuries to make the subtle, nuanced, pedigreed wines from Europe. Leading red vinifera varieties are Cabernet Sauvignon, Cabernet Franc, Pinot Noir, Merlot, et al. Leading white vinifera are Sauvignon Blanc, Reisling, Chardonnay. American Vitus labrusca varieties are the strong, grapey(known as foxiness in wine circles), table grapes such as Concord, Catawba, and Niagra.
Now, here's where the history got interesting(at least I thought so). Apparently, when the first American settlers hit Roanoke Island in 1584, they found a land full of wild grapes, later known as the Vitus labrusca varieties. There is evidence of these settlers, Captain John Smith in particular, trying their hand at wine making as early as 1606 but even then found that "Neither doth the taste so well please when they are made in wine." Later settlers reasoned that where wild grapes flourished in North America, European vinifera grapes would also grow well. There were endeavors to plant vinifera vineyards in every colony of the New World by the late 1600's. Without exception, the vines died from mysterious illnesses that did not affect the native varieties. So fine European wines could not be produced in America, probably much to the relief of European vignerons.
So what were the diseases that were killing the vinifera vines that enterprising settlers tried to introduce to the New World? The most virulent was a pest called phylloxera that attacks the roots of the vines, killing whole vineyards in one growing season. In the mid 1800's, this microscopic bug was to have an appalling affect on the centuries old wine traditions of Europe. During this time, American grape varieties were brought to Europe for study by wine enthusiasts. These American vines carried phylloxera, although they were immune to it. In the blink of an eye, thousands of hectares of European vineyards were wiped out by phylloxera. Some regions have not recovered to this day! But here's the kicker....the only way to save the European wine industry was to graft the regal vines of Europe to tough, wiry American rootstock. Terror in the terroir! C'est impossible! Cabernet Sauvignon with Concord roots? What ignominy...
From this ghastly time in wine history forked a new branch on the wine grape family tree: French-American hybrids. These hybrids were a cross between vinifera varieties for the fruit quality and American grapes for toughness and disease resistance.
