by Carmela Guaglianone, SF Examiner As sheets of rain and hail pounded parts of San Francisco Tuesday, Michael Baldacci, owner and winemaker at Baldacci Family Vineyards, looked out his window at the renowned Stags Leap District in Napa County and saw his cover crops coming to life.
Although intense storms continue to wreak widespread damage across the state, the wet weather is a boon for winemakers, who have long been waiting for the rain. “It just feels like we’ve been kind of praying for this,” said Baldacci. “The rains really have been something that we’ve welcomed the last couple of weeks.” Had this storm surge come later in the season, vintners may have been whistling a different tune. But the grapevines are currently in their winter dormancy, a stage between harvest and bud break when the vine drops its leaves and goes into a protective mode for the winter months. During dormancy, “all rain is good rain,” said Justin Leigon, viticulturist and board member of the Napa Valley Grapegrowers. That means there won’t be any direct impact on the grapevines or the wine that they produce, said Megan Bartlett, a plant biologist at the UC Davis Department of Viticulture and Enology. However, wet and humid conditions could increase the chance for fungal disease later in the season.

With extreme rain and storm conditions across the greater Bay Area, we recommend following these best practices during rainy winter months.
Subsurface drain tiles, sump pumps, and other vineyard “dewatering” systems are important and highly impactful farming tools. However, when run all winter long, they can waste electricity and prevent saturating rains from recharging our subsurface aquifers. Consider turning your sump pump OFF until much closer to bud break. When set to “auto” for the winter season, we risk unnecessarily adding more runoff to our swelling streams, creeks, and the Napa River. Saturated soils generally do not damage vineyard root systems during the dormant season; therefore concerns are minimal for vine impact. IMPORTANT NOTE: drainage and pumping systems are critical to maintaining roadway access or preventing water from entering wineries and damaging other types of sensitive infrastructure. In these cases, systems need to remain operational. Benefits to turning off sump pumps include:
NVG's Low-Smoke Burning Technique & Other Alternatives
Permitted burn season runs from October through April. One of the easiest and most cost-effective alternatives to smoky burns for growers to implement is NVG’s Low-Smoke Ag Burning Technique. Use NVG's step-by-step manual available in English and Spanish to reduce black carbon, preserve air quality, and conduct virtually smoke-free burns! Burning is an essential practice with no alternative when it comes to preventing the spread of vine pests and diseases. In addition to NVG's Low-Smoke Burning Technique, the use of fireboxes such as Airburners can also deliver a clean burn. For vines not compromised due to pest and disease issues, other alternative methods include chipping and grinding. NVG's Vine Disposal & Open Burning Resources
Saint Helena, CA (10/27/2022) - The 2022 harvest has concluded for most wineries and growers across Napa Valley. With climate variability as the new normal, Napa Valley grape growers aim to be the tip of the spear when it comes to resiliency and adaptability. This year, their preparation and experience paid off. Winemakers are referring to 2022 as “the tale of two harvests," making it one of the more unique vintages in recent history.
NOTES FROM THE VINEYARD (from the Napa Valley Grapegrowers) In March, bud break started in Carneros and throughout some mountain appellations. Leading into May, the vines showed strong shoot growth and average crop yields. Early July kicked off veraison and the countdown to harvest began. When faced with heat and rain events this year, grape growers showed foresight. “August provided warm days and cool nights, perfect for ripening. Then in September, we experienced a 5-day-long heat wave in the triple digits, which shifted our farming and harvest plan…but we’ve been preparing,” said Macy Stubstad, Director of Vineyard Operations for Lawrence Wine Estates. “We use a range of different trellis systems that splits and flops the canopy over the vines to protect the crop from strong morning and afternoon sun, allowing the fruit to retain acidity and freshness.” Soon following the heat spike, Napa Valley received 0.6 – 1.2 inches of rainfall. “Crews opened up canopies for airflow, which alleviated mold and botrytis and allowed us to harvest clean fruit,” said Stubstad. And for Matt Ward, winemaker for Pride Mountain Vineyards, the rain event “plumped up” fruit still hanging on the vines. With harvest complete, growers will ready for winter rainfall. They will put erosion control plans to work, spread compost throughout vineyards, aerate soils and prepare to seed for cover crop. NOTES FROM THE WINERY (from the Napa Valley Vintners) The white wine harvest kicked off in early August, followed quickly by red wine varieties. The typical gap between the white and red wine harvest was almost nonexistent, and the frenzied tempo continued until the rains came and the weather cooled in October. “I’m calling 2022 a tale of two harvests. From August to mid-September it was intense and fast-paced. The rain in mid-September created a gap and sudden halt to harvest. The fruit that came in after had beautiful mild weather in early October and lots of time to get to perfect ripeness,” said Elizabeth Vianna, Winemaker and General Manager at Chimney Rock Winery. Winemakers describe the 2022 white wines as having perfect acidity and freshness with remarkable flavors and textures, and red wines as excellent structured with deep red colors, luxurious tannins and exquisite fruit-forward aromatics. Josh Widaman, Estate Winemaker at Pine Ridge Vineyards, thinks “this will be a vintage that showcases the full range of flavors that Napa Valley wines are so well known for, from zesty and vibrant to dense and powerful.” As noted by winemaker Macario Montoya of Roots Run Deep Winery, "Each vintage tells a story that is unique and can never be replicated. We’ll remember 2022 as a vintage of craze and beauty. As the wines go to bed for the winter, we’re excited about their potential and the story they will continue to tell."

By Kenny Martin, Wine Spectator On Aug. 27, nearly 600 wine aficionados flocked to Oakville's Renteria 360 Vineyard for the 15th annual Harvest Stomp auction, a night of live music and great food for a worthy cause. This year’s event raised $3.3 million, surpassing last year's total by $600,000. Harvest Stomp supports Napa Valley Grapegrowers (NVG), which seeks to promote and preserve Napa vineyards, and the Napa Valley Farmworker Foundation, founded by NVG in 2011 to provide educational opportunities, English literacy programs and more for farmworkers.
The auction "celebrated the American and migrant farmers, caretakers of the land and all the families building a legacy for Napa Valley agriculture," according to its website. Harvest Stomp and its beneficiaries also advocate for change on issues such as climate resiliency, wildfire protection and sustainable agriculture. "It was great to be with people who care so deeply about the Napa Valley and its farmworkers. The generosity shown in this 15th anniversary year of Stomp was unmatched," said auction co-chairs John and Michele Truchard, owners of JaM Cellars and FARM Napa Valley Vineyard Management, in a statement.

As California enters the height of fire season, Napa wine and hospitality groups have joined forces in an effort to stop blazes from getting out of control. With government resources spread thin and a wildfire prevention initiative failing to pass in Napa in June, private organizations are stepping in. Together, the Napa Valley Grapegrowers, Napa Valley Vintners and Visit Napa Valley are spending $33,000 per month for around-the-clock monitoring of artificial intelligence-powered cameras that can detect a fire within seconds of starting. But the collaboration is only a temporary solution. While it will hopefully help keep residents and businesses safe through the current fire season, the groups also want to send a clear message to Napa County to do more next year. The Napa Valley Grapegrowers, Napa Valley Vintners, and Visit Napa Valley have joined together to fund three early detection wildfire sensors on Atlas Peak, Clover Flat, and Diamond Mountain with 24/7 monitoring to protect Napa County residents and businesses from wildfires. The three organizations have assumed financial responsibility for the service through the months of September, October, and November 2022: the peak of Napa County’s fire season, covering some of the County’s highest fire-risk areas.
The Illumination Technologies (ITC) state of the art “IQ FireWatch sensors” triangulate locations of potential fire threats, including identifying specific parcel numbers in Napa County. This program was initiated in 2021 by Napa County and was maintained through public funds. Continued funding was expected to come from the ¼ percent sales tax proposed in Napa County’s Measure L, which unfortunately did not pass. To fill the gap, local grape growers Caymus Vineyards, E. & J. Gallo Winery, and Circle R Ranch & Vineyards generously donated funds to keep the sensors active during the beginning of the 2022 fire season. When the service was set to discontinue on August 31, 2022, the Napa Valley Grapegrowers, Napa Valley Vintners, and Visit Napa Valley stepped up to ensure early detection services continue uninterrupted through the end of this fire season. This partnership is a model for community-based resiliency work in the face of increased fire and climate risks that have greatly affected the Napa Valley community over the last several years. “When we realized the service was at risk of shutting down, these organizations sprang into action to ensure the sensors stayed on. Early detection is a valuable tool in the toolbox when it comes to protecting the entire community from the wildfires like we’ve experienced over the last several years. Now with the partnership between Napa Valley Grapegrowers, Visit Napa Valley, and Napa Valley Vintners, this program will continue to safeguard the Napa Valley community through fire season. We’re proud to carry this community-first, collaborative initiative forward,” said Tom Davies, president and part-owner of V.Sattui Winery, who sits on the Napa Valley Grapegrowers Board of Directors, is the FY23 Chair of Visit Napa Valley Board of Directors, and is a long-time member of the Napa Valley Vintners. The three existing cameras currently cover 48% of Napa County in high-risk areas. As part of this initiative, Napa Valley Grapegrowers, Napa Valley Vintners, and Visit Napa Valley are committed to working with other industry and community partners during this fire season and onward to implement a long-term plan for maintaining ongoing early detection services and expanding coverage to more areas throughout the County. To support funding for the wildfire detection sensors, please email Molly Moran Williams, NVG Industry and Community Relations Director, at mwilliams@napagrowers.org. On Monday, as temperatures reached record highs, the NVG-funded wildfire sensors were first to detect a fire in the Oakville/Yountville area enabling the Fire Department to get it under control right away. Additionally, NVG is awaiting reports on three additional fire detections picked up by the sensors and kept under control within the last 24 hours. With the heat advisory still in effect, we are grateful to have 24/7 early fire detection still in place in high-risk areas of Napa County.
In August, NVG announced carrying forward a fire detection initiative funding three early detection sensors for the month of September on Atlas Peak, Clover Flat, and Diamond Mountain with 24/7 monitoring to protect Napa County residents and businesses from wildfires. As part of this initiative, NVG has also committed to working with industry and community partners to ensure detection through the 2022 fire season while scoping how to maintain early detection for the long-term for Napa County. NVG will carry forward a fire detection initiative, funding three early detection sensors for the month of September on Atlas Peak, Clover Flat, and Diamond Mountain with 24/7 monitoring to protect Napa County residents and businesses from wildfires.
The Illumination Technologies (ITC) state of the art “IQ FireWatch sensors” triangulate locations of potential fire threats including identifying specific parcel numbers in Napa County. This program was initiated in 2021, funded by Napa County. However, without the passing of Measure L, the service could no longer be maintained through public funds. Through the generosity of local grape growers, the sensors have continued to protect the community through the month of August. NVG will be taking on fiscal responsibility for the service through the month of September, at the peak of harvest and Napa County’s fire season—and in some of the County’s highest fire-risk areas. “When we realized the service was at risk of shutting down, NVG leadership sprung into action to ensure the sensors stayed on. Early detection is a valuable tool in the toolbox when it comes to protecting the entire community from the wildfires like we’ve experienced over the last several years. We’re proud to carry this community-first, collaborative initiative forward,” said Tom Davies, who sits on NVG’s Board of Directors, Industry Issues Committee, and Wildfire Task Force. As part of this initiative, NVG also commits to working with industry and community partners during the month of September and onward to implement a long-term plan for maintaining ongoing early detection services and expanding coverage to more areas throughout the County. NVG would like to recognize the incredible generosity and stewardship of Caymus Vineyards and Circle R Ranch & Vineyards for their individual contributions that allowed the ITC service to remain in place through August in service to the entire community. In addition to this initiative, the NVG Wildfire Task Force is engaged with several other projects including:
USDA has released disaster assistance funding for producers that sustained losses due to wildfire, smoke, heat, and more in 2020 and 2021. NVG has continually advocated for disaster assistance for members following the 2020 wildfires and is grateful to Congressman Thompson for his continued efforts in securing this critical funding. The WHIP+ program has been renamed the Emergency Relief Program (ERP). Funds will be released in TWO PHASES, beginning with PHASE 1 producers.
