The Cabernet Franc vines are flourishing under sunny blue skies at the Crane Creek Vineyard in rural northwestern Georgia...Cabernet Franc is believed to have been established in the Libournais region of southwest France sometime in the 17th century when Cardinal Richelieu transported cuttings of the vine to the Loire Valley. They were planted at the Abbey of Bourgueil under the care of an abbot named Breton, whose name became associated with the grape. By the 18th century, plantings of Cabernet Franc (known as Bouchet) were found throughout Fronsac, Pomerol and St-Emilion, making quality wines. As Cabernet Sauvignon became more popular in the 18th & 19th century, the close similarity of the two grapes was observed and theories emerged as to the extent of the relationship. In 1997 DNA evidence emerged to show that Cabernet Franc crossed with Sauvignon blanc to produce Cabernet Sauvignon.
In general, Cabernet Franc is very similar to Cabernet Sauvignon, but buds and ripens at least a week earlier. This trait allows the vine to thrive in slightly cooler climates than Cabernet Sauvignon, such as the Loire Valley. In Bordeaux, plantings of Cabernet Franc are treated as an "insurance policy" against inclement weather close to harvest that may damage plantings of Cabernet Sauvignon. Its early budding does pose the viticultural hazard of coulure early in the growing season. The vine is vigorous and upright, with dark-green, 5-lobed leaves. The winged bunches are elongate and small-medium in size. The berries are quite small and blue-black in color, with fairly thin skins. The Cabernet Franc grapevine is more prone to mutation than Cabernet Sauvignon, less so than Pinot noir.
Cabernet Franc can adapt to a wide variety of vineyard soil types but seems to thrive in sandy, chalk soils, producing heavier, more full bodied wines there. In the Loire Valley, terroir based differences can be perceived between wines made from grapes grown in gravel terraces versus tuffeau slopes.
