China imports quite a bit of wine, however, very little comes from the United States. At the same time, per capita consumption of wine in China remains very low. So why are California winemakers anxious about tariffs newly imposed by China on U.S. wine? Because China's wine consumption habits are expected to change, reported UC ANR experts in an article posted on The Conversation and NPR websites.
"China is the world's fastest-growing wine market and is expected to soon become the second largest (wine market), after the U.S.," wrote UC Davis wine economist Julian M. Alsten, director of UC ANR's Agricultural Issues Center Daniel Sumner, and post-doctoral scholar Olena Sambucci.
Economists who have studied these markets project further significant growth in China's demand for wine, including premium wine imports, the article said.
"This would make getting pushed out of China especially troubling at a time when global per capita wine consumption has been declining, especially in Europe," the authors wrote.
With the value of wine riding on a delicate balance of aroma and flavor, the impact of winegrapes' exposure to smoke from a wildfire could have significant economic consequences. Last fall's Northern California wildfires sent smoke wafting over an experimental vineyard in Napa Valley, giving scientists the opportunity to study the interplay of smoke and wine quality, reported Jeff Quackenbush in the North Bay Business Journal.
"The moment the smoke started, my phone started ringing off the hook," said Anita Olberholster, UC Cooperative Extension viticulture and enology specialist. “I quickly realized how thin the data is I need to base recommendations on.”
The fires near the UC Davis vineyard provided the perfect experimental platform. Olberholster and her research team sprang into action to start a research project on the fly. Remaining grapes on smoke-exposed vines were picked, loads of commercially grown grapes deemed too questionable for commercial wineries were accepted. Over the past five months, small batches of wine were made from the grapes.
“They all have different levels of smoky character,” Olberholster said. “Some on the nose are actually quite pleasant and not smoky, but the aftertaste is the problem. All of them, even if in small amounts, had that ‘old smoke,' ‘ashtray,' ‘new smoke' aftertaste. It all depends on how sensitive you're going to be at it.”
The scientists are now looking for a process that will remove the smoky compounds, as little as possible of anything else.
Lindsay Jordan is growing 56 varieties of grapes at the UC Kearney Agricultural Research and Extension Center to see how varietals from other parts of the world flourish or fail, reported Sydney Maki in the Fresno Bee.
The front-page story provided an overview of Jordan's career, research plans and personality.
“My love of wine drives a lot – what can I say,” Jordan said. “I don't know about you, but I want to keep drinking wine until the day I die, so I really want to do my part to ensure the sustainability of drinking California wine.”
As part of the project, Jordan is looking for grapevines that thrive in the valley heat, produce a large crop and develop berries with color, flavor and acidity needed for fine wines.
"I won't declare any winners," Jordan said. "I'll say I have favorites, and I definitely have losers that I would not recommend.
The project was started by James Wolpert, a retired UC Cooperative Extension viticulture specialist, and continued by Matthew Fidelibus, UCCE viticulture specialist based at Kearney. Jordan took over the project a year and a half ago.
Finding the next cabernet sauvignon or chardonnay would be a home run, Fidelibus said. However, the data supplied by the project are also important in providing farmers and wineries the research and background to expand their own vineyards.
“If any of these varieties are going to be useful, it's important that the wineries are interested and comfortable with them,” Fidelibus said. “The grower can't grow varieties without the assurance that a winery is going to use them.”
This time of year, most farmers don't get much sleep. Tomatoes, pears and peaches often ripen in the Sacramento Valley faster than the harvest crews can pick them, even working 12-hour days. But this is also the season that some farmers are happy to show off their farms to visitors, inviting guests to enjoy the delightful flavors and beauty of the harvest in a pause from the bustle. UC Cooperative Extension hosts an online agritourism directory and calendar, www.calagtour.org, to help Californians find farms and ranches to visit. Here are a few upcoming opportunities for summer fun on California farms, pulled from the calendar:
- Good Humus Peach Party (Yolo County) - Every year on the first Saturday in August, Jeff and Annie Main, owners of 20-acre Good Humus Produce, hold a celebration to give thanks for the year's fruit harvest. They invite you all to come out, see the farm, have a refreshment and enjoy all that Good Humus has to offer. This is a pot luck party; guests are asked to bring a dish to share and their own plates, silverware and cups. No cost, but donations are welcomed. The Mains will provide peach pies, peach ice cream, peach salsa, peach pizzas, and more. You are invited to come early and be part of the experience of making all the peachy fun food. Other activities include a treasure hunt, farm tours, stock tank dipping, music and neighborly chat. Saturday August 6, 1 p.m. - 11 p.m. Learn more

In 2008, a disease characterized by red blotches along leaf margins and red veins under the leaf surfaces was seen in red grapes growing in Napa Valley. The symptoms resembled leafroll disease, however laboratory tests did not detect any leafroll and rugose wood viruses in the samples. Since then, red blotch disease has been observed in vineyards throughout North America.
The infected grapevines may produce clusters with reduced sugar content, causing delayed harvests. Poor color development and increased acidity are found in some clusters on diseased vines.
A virus associated with red blotch disease was identified in 2012. The incidence of the red blotch disease relative to other virus diseases is currently not known, according to the UC IPM Pest Management Guidelines. The guidelines, produced by UC Agriculture and Natural Resources' (UC ANR) Statewide Integrated Pest Management Project, offer comprehensive information free online for pest control in more than 50 California crops.
UC ANR Cooperative Extension specialist, Deborah Golino, director of Foundation Plant Services at UC Davis, wondered if the virus associated with red blotch disease was new to California. She turned to the UC Davis Herbarium, a repository of 300,000 pressed plant samples, including grapevines dating back to 1940.
Golino and her laboratory staff collected 56 samples and, to prevent contamination, tested them in a lab that only works with lettuce. Of the 56 samples, one, an early burgundy collected in Sonoma County, was positive.
“We have confirmed that red blotch disease is not new,” Golino said. “It's been around at least since 1940.”
The results were published this year by the American Phytopathological Society in the journal Plant Disease.
An initiative to manage endemic and invasive pests and diseases is part of UC Agriculture and Natural Resources Strategic Vision 2025.
