The conversations I have about quality tend to focus on red wine. This is especially true in California, where Napa Cabs have historically garnered high prices, followed up by Coastal Pinot noirs and red Rhones. Honestly, in most places I’ve been where the climate allows for ripening red grapes, the reds are the main event with the whites being more of a warm-up act or even an afterthought. As a result, we know a lot about how to grow red grapes for quality – and less about how to grow whites. Consumer tastes are shifting though, and the big reds of yore are taking a back seat. Drinkers want lower alcohol wines with a lighter style and wineries are taking fewer risks with wine they can turn around in under a year. As a result, white varieties are in hot demand. If you’re a grower who can’t sell your grapes, you may very well be considering grafting some of your reds over to white.  So how do you grow a good white? In many ways whites are harder than their r

In the 1880s, Pierce’s disease caused a devastating, total collapse of the Southern California grapevine industry. Today, growers have hope for the future thanks to new varieties. Adam Tolmach, owner of Ojai Vineyard, planted four of these new varieties as a field trial on a plot of land where Pierce's disease wiped out his grapes in 1995.  Pierce’s disease is a bacterium spread by insects, typically a sharpshooter. One bite and the vine dies within two to three years. To develop resistant varieties, Andy Walker of the University of California at Davis crossed the European grape Vitis vinifera with Vitis arizonica. 20 years later, commercial growers have access to three red and two white varieties. Listen in to learn how Tolmach’s experiment is a success both in the vineyard and with customers. Plus get tasting notes for the new varieties.

Pierce's Disease has been a scourge of vineyards for well over a century. It was discovered near the end of the 19th century by Newton Pierce, so the disease took on his name after originally being given the name Anaheim Disease (having been discovered in that area’s vineyards well before Disney and all that pavement moved in). Pierce’s Disease (PD) is a nasty disease caused by the bacterium Xylella fastidiosa, which is vectored by several different sharpshooter insects, including blue-green, red-headed and glassy-winged. The bacteria colonize the xylem vascular tissue. The bacterial colonies, along with gums that are exuded by the vine itself, clog the vessels and effectively choke off the vine’s water transport system. The disease is catastrophic in that it cannot usually be surgically removed from the vine and will most often quickly reduce both its fruit production and fruit quality before finishing off the job and killing the vine after a few years. It is n
