Ciatti Global Wine Market Update – November 2014

The harvests have all come to an end in the Northern Hemisphere, and it looks as though France has regained its position as the largest producer in the world. French growers looked to have rebounded from disappointing volume results in 2013 with a much better looking crop in 2014. While all regions did not participate in the gain, as Languedoc notably did not have large output, the French growers overall are feeling good about…

Using Soil Moisture Sensors for Vineyard Irrigation Management: A Practical Guide for Installing and Interpreting Information from Soil Moisture Monitoring Technologies in Vineyards – Part III

Thanks for reading this three-part series about using soil moisture sensors to inform irrigation management in vineyards. Part I focused on selecting locations to install soil moisture sensors. Part II took a look at depth of sensor placement and proximity to drip emitters and vines. Here, in Part III, we will cover common types of soil moisture sensors and tips for installation. Common Types of Soil Moisture  Sensors and Tips for…

Using Soil Moisture Sensors for Vineyard Irrigation Management: A Practical Guide for Installing and Interpreting Information from Soil Moisture Monitoring Technologies in Vineyards – Part I

Grape growers are encouraged to use a combination of soil, plant, and weather data when determining the length and frequency of irrigation events in vineyards. The most common questions growers want to answer with regard to vineyard irrigation are: How often should the vineyard be watered? How much water should be applied per irrigation? Estimation of daily evapotranspiration can tell a grower roughly how much water is removed from the…

Farm Labor in California’s Specialty Crops

The Census of Agriculture (COA), which provides the most complete profile of the nation’s farming sector, highlights the importance of fruits and nuts, vegetables and melons, and horticultural specialty (FVH) crops in California. The farm value of U.S. FVH commodities in 2012 was $57 billion or 27% of U.S. crop sales, while California sales of FVH commodities of $26 billion were 87% of California crop sales. The importance of FVH…

Allocation-Based Water Pricing Promotes Conservation While Keeping User Costs Low

October 6th, 2014

The common approach for pricing water and other goods and services in a market economy is uniform pricing: each unit is priced the same regardless of the amount consumed and the characteristics of the consumer. Block (or tiered) rate pricing is where the cost per unit varies with the amount consumed. Increasing (decreasing) block rates refer to the case when the first units are priced relatively low (high) and subsequent…

Leafroll 3 Virus Testing Reagent that Could Impact State Certification Programs

Leafroll 3 Virus Testing Reagent that Could Impact State Certification Programs

Grapevine leafroll associated virus 3 (GLaV-3) is, arguably, the No. 1 most economically important virus in grapevine production and is designated as an exclusion pest in most certification programs. However, growers are often frustrated to find this virus in their vineyards and in certified nursery stocks.  Since GLRaV-3 is known to be genetically highly variable, we suspect that certain strains may have escaped detection during certification. “Such genetic variability has significant implication in the…

Effect of Light Environment on Methoxypyrazine Content of Cabernet Sauvignon

Sunlight levels can affect a variety of fruit characteristics in winegrapes. This research focused on how light levels impact the presence of a class of aroma compounds, methoxypyrazines (MPs), which are responsible for vegetal aromas such a green bell peppers, green peas, and asparagus. This study examined the effect of light and/or heat on the accumulation of MPs in Cabernet Sauvignon. The results indicate that shaded clusters accumulated more MPs,…

Beware of Dubious Agricultural Terms

The language of agriculture and wine grape growing is constantly evolving and we seem to come across new words all the time. Ultimately, the goal of all new words should be to improve our ability for clear and concise communication. Some additions to our lexicon are more successful than others in achieving this goal. Here, I will address four recent terms that I believe have fallen short in improving the…
