California's drinking age of 21 prohibits many undergraduate students from learning critical skills early in their academic careers — sensory skills that they will need when they move on to jobs in the multimillion-dollar winemaking, brewing, and food industries.
Not until students turn 21 can they taste the wine and beer they make and learn to assess its sensory quality. Learning the characteristics of a wide assortment of good (and not-so-good) wines and beers is an important component of winemaking and brewing. Having to wait until their junior or senior year to learn these skills is a disadvantage for these students.
Legislation (AB 1989) has been proposed by California Assemblyman Wesley Chesbro (D-North...

While many of us cherish the mystique of popping a wine cork, screw caps are becoming more commonplace in the wine industry. Half a century ago, screw caps were associated with cheap rotgut wine, but now they have replaced corks in many premium wines and at many of the world’s best wineries.
Wine bottles are sealed primarily in three ways — natural corks, synthetic corks or screw caps. All have their advantages and disadvantages, and most certainly their proponents and opponents. While synthetic corks never gained much of a foothold in the wine industry, screw caps are being studied more frequently for their efficacy and quality.
While screw caps were originally thought to be airtight, resulting in the...

Nearly half of the 55 unusual winegrape varieties in a plot at the UC Kearney Agricultural Research and Extension Center in Parlier displayed enough promising characteristics to prompt a cooperating vintner to make 25 small lots of wine.
The research at Kearney is designed to expand the wine industry’s options in the San Joaquin Valley, currently California’s top grape growing district in terms of production, but lowest in terms of price.
“Most of the popular wine varietals – Merlot, Cabernet Sauvignon, Chardonnay – are at their best in somewhat cooler climates. So we are looking for grapes that make superior fruit in warm climates,” said

A new winery, brewery and food-processing complex began operations this fall at UC Davis. Part of the Robert Mondavi Institute for Wine and Food Science, the technologically sophisticated facilities will be used to teach students, conduct research, and solve practical problems related to foods, beverages and health.
The south wing of the new complex is home to the August A. Busch III Brewing and Food Science Laboratory, which includes the brewery, general foods-processing plant and milk-processing laboratory. The complex’s north wing houses a new teaching-and-research winery. The complex is adjacent to a 12-acre teaching-and-research vineyard and across a courtyard from the departments of Food Science and Technology,...

August visitors to California wine country can see winegrapes ripening – green changing to gold, red and purple. This is the critical final stage of development, and its success drives one of the state's economic engines, with wine sales generating $18 billion in revenue in 2009. Wine country is also a tourist magnet and a job generator; the industry has a $61.5 billion economic impact statewide each year.
If this is a typical year, California will produce 90 percent of the nation’s wine. In normal vines, the ripening period means sugars and pH increase, while acids (primarily malic) decrease. Other compounds such as tannins develop, and all these factors contribute to the flavors and aromas in the wine that eventually results....
