Wildfires and COVID impacted legislation as much as they impacted wine production this year. Lauren Noland-Hajik, Attorney and Lobbyist at Soares & Conway coves some of the major changes seen in 2020 and what is coming up in 2021. The March shutdown of the legislature due to COVID resulted in the handing off of power from the legislature off to governor to make executive orders. This is a scenario that has not been seen in a long time and was still in place as of the end of 2020.

Second generation owner of the Original Wine of the Month Club and host of the podcast Wine Talks, Paul K. knows you need to taste a wine to know if it is good. Decades in the industry have taught Paul that a sustainable business means being able to go to market through different routes so consumers can buy at varying price points. Paul reflects on shipping challenges from reporting to taxes; misconceptions about the quality of wine coming from the bulk market; and the slow road to pivot from on premise sales to online post COVID.

In mid-April 2020, the grape market saw its highest bulk inventory at 23 million gallons. By November that quantity had reduced significantly to 8.5 million gallons. Audra Cooper, Central Coast Grape Broker and Partner at Turrentine Brokerage explains how the grape market has been on a roller coaster throughout 2020.

The Spotted Lanternfly (SLF) is the newest agricultural invasive species in the United States. Originally from Asia, this insect feeds on plant sap from a broad range of hosts. Dr. Heather Leach, Extension Associate at the Department of Entomology at Penn State University is focused on researching this insect and educating the public on how to manage the pest. Although it appears that SLF has been in the United States for some years, growers are now seeing adverse effects and report extreme vine decline and death.

Today, 40% of the California wine industry does not have a Farm Advisor. Four industry veterans discuss retirements and recruitment for UC Cooperative Extension and brainstorm how the industry can fill this void through PCAs, consultants and organizations like the Vineyard Team and Lodi Winegrowers.

Leading expert Dr. Andrew Landers of Cornell University discusses his more than thirty years of research and development on pesticide sprayer technology to reduce pesticide use through accurate, efficient delivery of the product to the plant.

A recent study examined the potential of hemp terpene drift from hemp crops planted in close proximity to vineyards in Sonoma County, California. George Sellu, Program Coordinator and Instructor in the Agribusiness department at Santa Rosa Junior College explains the nuances of hemp production from how volatile aroma profiles vary by variety, the lack of studies to show volatiles impact grapes, wind influence on volatile organic compound movement, and smoke taint.

David R. Montgomery defines regenerative agriculture as leaving the land better off and more fertile as a consequence of cultivation. In this research, he has defined three principals to build soil fertility; minimal disturbance, cover cropping, and growing a diversity of crops. David has studied the success of these principals in agricultural systems around the world, from subsistence farmers to large commodity crops in North America.

Dr. Charlotte Decock, Assistant Professor Cal Poly - Earth & Soil Sciences talks about soil management with the goal of capturing greenhouse gasses from the atmosphere and sequestering them in the soil. Her teaching and research focus on sustainable fertilizer and soil management in California’s specialty crops.

Some 25 to 30 percent of vineyards in Washington state have nematode population densities that are considered damaging. Inga Zasada, Research Plant Pathologist with the USDA Agricultural Research Service is particularly interested in nematode management because Washington is mostly own rooted vines. Inga and her team are working on practical research for growers including identifying where different types of nematodes are in relation to the vine and a degree day model for nematode life stages so if chemical becomes available it can be used property.

Steven Lindow, Professor of Plant Pathology at the University of California Berkley is a plant pathologist and microbial ecologist. He and his team are researching other bacteria that can grow in the grapevine that mysteriously sensitize them to the Pierce’s Disease pathogen. Once inoculated with the new bacteria the plant induces its innate immune system to combat Pierces Disease. This process works like a vaccine although the bacteria itself does not cause a direct action.

50-million-year-old reserves of humified organic matter are a substance called lignite. It is commonly known as brown or soft coal, a substance usually equated with energy production. Researchers at the Technical University of Dresden have found that this very old, carbon rich plant material has the same building blocks as humus – the organic matter reserves found in soil. Virginia Corless, Chief Growth Officer at Novihum Technologies, explains how reacting lignite with nitrogen has created a new soil amendment to improve nutrient retention, water storage, and the vitality of the microbiome.

Bruce Reisch, Professor of Grapevine Breeding and Genetics at Cornell University, specialized in the development of new wine and table grape varieties, as well as new grape breeding techniques. Of the more than 60 grape species available, most of the grapes we are familiar with come from European vitis vinifera. Unfortunately, this species offers little disease resistance, but other species have better sources.

While wineries can maintain business operations during COVID-19, day to day operations look much different than they did the first few months of 2020. Hear how three wineries are adapting to their new way of doing business.

Paul Mabray, CEO of Emetry is helping wine brands make more effective sales and marketing decisions with data. He finds that wineries focus too heavily on finding new customers when they should put effort into retaining the ones they already have.

The Sustainable Winegrowing podcast's new Wine Marketing Series is full of information you don't want to miss.

Beginning at version, grapes become a very attractive food for pest birds, particularly Sparrows and Starlings. Initially the vineyard is explored by small flocks of scouting birds. If those birds like the fruit, and if there is no obvious danger, the entire flock will follow. Falcons terrify pest birds, herding them away from the grapes, but not killing them.

Sustainability and certification are viewed as a “quality enhancement”. In the currently overly supplied market, sustainability is an advantage. A premium can be getting $200 to $300 more per ton of grapes in a good market or it can mean selling grapes when no one else can in a weak market. Gregg Hibbits, General Manager at Mesa Vineyard Management explains how their dedication to sustainability for over 30 years has drawn like-minded customers to their organization.

Brandi Moody explains that to develop a strong marketing strategy you need to know your consumer segments, learn about them, see what they like, and market to them where they are.

We were already experiencing a market correction before COVID-19, so what can wineries do now and in the future to connect with their consumers and sell wines?

Dr. Michelle Moyer, Assistant Professor and Statewide Viticulture Extension Specialist at Washington State University uses the age old fairytale of Goldilocks and the Three Bears to explain powdery mildew. Like Goldilocks, powdery mildew likes the weather conditions to be just right. Dr. Moyer explains these ideal conditions and two key ways to avoid disease in your vineyard by making things “not right”.

Wayne Wilcox, Professor Emeritus of Plant Pathology and Plant-Microbe Biology at Cornell University, spent his career on the applied biology and integrated management of grapevine fungal diseases. His applied research sought to discover what makes a “disease tick” and use that knowledge to learn how to better target the disease.

Grape vine trunk diseases are prevalent in mature vineyards, shortening the vineyard’s life and productivity. Akif Eskalen, Cooperative Extension Specialist and Plant Pathologist at the Department of Plant Pathology at the University of California Davis, is researching naturally occurring microorganisms to use as biocontrol against these fungal pathogens.

One decade ago, amidst a limited labor supply and growing New Zealand wine industry, Klima co-founders Marcus Wichkam and Nigel George set out to solve their own labor issues with mechanization. By developing a highly efficient vineyard pruning system they have removed the physically demanding portion of the job opening the opportunity to employ fewer, more highly skilled tradesworkers to perform cane selection.
