B is for Baco 22A

Most of the wine we drink is made from grapes from the Vitis Vinifera species.  Vitis is the genus for many vine plants and vinifera comes from the Latin “to bear or carry wine”.  This species started out in what is now Iran and made its way out of the Middle East and into the Mediterranean.  From there, the Greeks spread the vines to North Africa and southern Italy.  The Romans then brought them along as they began occupying the western part of Europe, as early as the 1st century B.C.

Simultaneously, North America had land under vine, but the vines were all non-vinifera species, with fun names like Vitis labrusca, Vitis riparia and Vitis aestivalis (there are 15+ total).  When phylloxera (insect/epidemic that kills grapevines) struck Europe, they didn’t want to plant our vines, but they were interested in our phylloxera-resistant rootstock.  The solution was grafting the more desirable vinifera vines onto the  hardier American species. 

Grafted Riesling vine. Grafting is done by cutting a cane (stem of a mature grapevine) of the desired variety in a way that it will fit into a matching cut made in the selected rootstock (think of a puzzle piece).

Grafting took many years to perfect, but it was just the beginning of experiments done by botanists.  By the late 1800s scientists were cross-pollinating different vine varieties and families.  French-American hybrids were born of these experiments.  The idea was to combine the winter-hardiness and phylloxera resistance of the American vines with the fruit and flavor of the French vines.  We’re still developing these varietals, particularly at the Cornell Viticultural Research Station in Geneva, New York. 

At one time hybrids accounted for several million acres of vineyards in France.  This is no longer the case, though hybrids can still be found in the eastern U.S. and Canada, and South America.  Interestingly, one hybrid has survived in France; Baco 22A.  Sometimes called Baco Blanc, it is a crossing of Folle Blance (acidic, French white, ravaged by phylloxera) and Noah (hardy American hybrid developed in the 1860s in Illinois), and was created by François Baco in 1898.  Until the late 1970s, Baco 22A was the primary ingredient in Armagnac.

Ugni Blanc now plays a bigger role than Baco22A, as French authorities try to rid their vineyards of hybrids.
