What Texas AVA crosses a state line?
Mesilla Valley (mostly in New Mexico)
How many vineyard acres in Texas? How does that size compare with Napa Valley?
5000 of which 3800 are bearing (National Agricultural Statistics Service - 2015), about 1/10th the size of Napa Valley

Black Spanish/Lenoir/Jacquez, Blanc du Bois, Muscat, Sangiovese, Tempranillo, Viognier
Black Spanish refers to what grape varieties?
Black Spanish is a synonym for both Jacquez/Lenoir (hybrid) and Listan Prieto/Mission (V. vinifera) grapes.
How many wineries are in Texas?
just over 200 active wineries, but 350 State-permitted entities (txwine.org)

What was Texas’s only commercial winery during prohibition?
Val Verde Winery
Who founded Val Verde Winery?
Frank Qualia

(wineamerica. org data, 2013: 7,946 total)
1. California (3,782) 2. Washington (681) 3. Oregon (599)

Who saved the European wine industry after phylloxera? Where was he from? What was his seminal contribution?
Thomas Volney Munson from Denison, Texas, found native Texas rootstock that could tolerate limestone soils and allow grafting of V. vinifera vines. Although these rootstocks did not achieve their intended function, hybrids from these did allow success.
What viticulture award did T.V. Munson win?
French Chevalier du Merite Agricole, 1888
Besides T.V. Munson, what other Americans also won the French Chevalier du Merite Agriole for their work on viticulture?
Hermann Jaeger (supplying rootstock from Missouri) in 1893 and Frank Lamson-Scribner (while working for the USDA, originally from Maine) in 1890
What are the 4 main AVA’s in Texas?
Texas High Plain, Texas Hill Country, Fredericksburg (sub-AVA) and Bell Mountain (sub-AVA). This assertion is dubious as the two sub-AVA’s do not produce much wine.
What is most important biological threat to Texas viticulture?
Pierce’s Disease
What is the vector of Pierce’s Disease?
sharpshooter insects (originally the blue-green, but now glassy winged)
What are the geographical determinants of Pierce’s Disease?
Primary: riparian; secondary: low altitude and southern climes. Only areas situated on the banks of a river (riparian) are susceptible. Disease is less prevalent where winter temperatures are cold, such as more northern areas, high altitudes and inland areas.
Which Vitis varieties are resistant to Pierce’s Disease?
Hybrids such as Blanc du Bois, Norton (Cynthiana) and Jacquez (Black Spanish) are resistant. Muscadine grapes (Vitis rotundifolia) have a natural resistance. There are no resistant Vitis vinifera varieties; Chardonnay and Pinot Noir are especially sensitive.
What are the main climatic threats to Texas viticulture?
Hail, drought, high winds, thunderstorms and spring frosts
What is the bacteria that causes Pierce’s Disease?
Xylella fastidiosa
What are the main reservoirs of sharpshooter insects?
The proximity of vineyards to citrus orchards compounds the threat, because citrus is not only a host for the sharpshooter eggs, but it is also a popular overwintering site for the insect. Likewise, oleander, a common landscaping plant in California, serves as a reservoir for Xylella.
What plants are the main plant targets of Pierce’s disease?
Grapevines, olive, almonds, citrus, stone fruits, alfalfa and oleander. Although different strains of this organism cause similar diseases in other crops, they appear to be host specific, i.e., the grape strain does not appear to infect peach and vice versa.
What is mechanism of Pierce’s disease?
It is caused by a xylem-limited bacterium that clogs the vascular tissue of susceptible grape cultivars.
