For more than two decades, Donum has been quietly crafting single-site, single-clone and sometimes single-barrel wines. With a new estate vineyard to their name, Rachael Ryan – Senior Buyer at our US arm, Vinfolio – sat down with winemaker Dan Fishman to find out more about the ambitious estate
Like most of the New World, California eschews a hierarchy of vineyards. Yet in the absence of Grands Crus and First Growths, some vineyards are just acknowledged as being a notch above the rest. Ask any winemaker for a wish list of vineyards, and a handful of familiar names is repeated. One of these is the Savoy Vineyard.
Nestled at the north end of the Anderson Valley, Savoy was first planted in 1991 and quickly became a source of Pinot Noir for some of the most respected wineries in Northern California, including Littorai, Williams Selyem, Radio-Coteau and Peay, with many more on the waiting list. Last year, however, it was acquired by Donum, a winery based in Carneros with a reputation for producing small lot Chardonnay and Pinot Noir, sold exclusively to private collectors and therefore rarely seen on the market.
Since it was created in 2001, Donum had slowly expanded its reach beyond Carneros, with vineyards in the Russian River and Anderson Valleys, as well as the Sonoma Coast. With the acquisition of Savoy, however, their already envious collection of vineyards took a very notable – and sizable – jump. The gain of this prestigious vineyard marks a shift for Donum, who will now produce wine from estate fruit only: 130 acres at their estate in Carneros, 16 acres at the Winside Vineyard in the Russian River Valley, 20 acres at the newly planted Bodega Vineyard on the Sonoma Coast, and the 42 planted acres at Savoy Vineyard in the Anderson Valley.
Already well-known for their world-class art collection (with over 50 works by the likes of Keith Haring, Yayoi Kusama and Ai Weiwei), what many visitors may not realise is that Donum now has a solid foothold in each of the premium Pinot Noir and Chardonnay winegrowing regions in Northern California.
In some ways, the vineyards owned by Donum are innately similar, perhaps most closely linked the marine layer. This dense fog rolls in from the Pacific Ocean most afternoons during the growing season and is a key characteristic of each of these vineyard sites. The mechanics of this cooling marine layer are somewhat straightforward. As temperatures climb in inland California, the hot air rises, creating a vacuum into which the denser, colder air sitting over the Pacific Ocean rushes. On a typical summer day, coastal areas are fully clouded over by late afternoon, and the fog continues to creep further inland, searching for gaps and valleys in the coastal ranges to extend its reach. This cold, moist air both lowers sunlight hours and keeps temperatures low. In other words, this coastal phenomenon is an extremely useful aide in the production of lively wines that retain a fresh edge.
Aside from cooling fog influence, however, the vineyards Donum farms are topographically quite different. The estate property in Carneros, with its gently rolling hills and proximity to the bay, straddles the southern portion of both Sonoma and Napa counties (though Donum’s property is firmly situated on the Sonoma side), with consistent winds blowing from the southeast over the San Pablo Bay giving the region a wide diurnal shift and the resulting wines a sense of energetic tension. The Anderson Valley, on the other hand, is a narrow swathe cut through dense, old redwood forest, and it's difficult not to mentally connect the rugged hills that line the valley on both sides with a similar evergreen, earthy core in the wines. The Russian River Valley is a warmer microclimate, further removed from the cooling influence of the ocean or bay, with loamy soils producing a more concentrated style of wine with opulent fresh fruit.
But for Dan Fishman (Vice President of Winemaking and Vineyards) perhaps the most unifying characteristic across each site is a hyper-focus on farming, which he believes is the best – and perhaps the only – way to showcase these unique terroirs. When he joined Donum in 2007 as a cellar intern, the farming was conventional, with routine application of herbicides and synthetic fertiliser. In recent years, however, he has spearheaded a pivot towards organic farming.
Notable features of this approach include an on-site composting program, where manure from local dairy farms is added to pomace from the winery and canes from pruning. Other eco-friendly initiatives include an integrated pest management system, extensive cover cropping (Fishman estimates Donum currently uses 20 different cover crop blends comprised of over 40 different plants), as well as animals brought into the rows for winter grazing. All these systems have improved the soil structure, “bringing more back to the soil than we’re taking from it”, he explains.
A peek into the rows at the Carneros estate reveals this shift in viticultural philosophy, with verdant cover crops and bees hovering. Tucked between the sculptures that dot the property are vines that are farmed meticulously. While the art is spectacular and very difficult to ignore, the attention to detail in the vineyards is perhaps even more impressive. Donum is now one of the first wineries in Sonoma County to achieve Regenerative Organic Certified (ROC) status for all its estate vineyards, and they’ve also been certified organic from the California Certified Organic Farming Association (CCOF) since the summer of 2022. The ROC status, however, is one that Fishman is particularly proud of, as it encompasses not just soil health and land management, but also animal welfare and the working conditions of the employees.
When asked if he has seen a difference in the behaviour of the vines, and in the quality of the fruit, since undertaking a rigorous approach to organic viticulture, Fishman’s answer is an emphatic yes. He points to the 2023 growing season as a prime example. In a year marked by record-breaking rainfall that extended into early spring, the threat of mildew was abnormally high. “Our conventional neighbors were spraying like crazy and still had mildew,” Fishman says, “but we were obviously using organic methods and applying them less frequently, and we had way less mildew. I think the vines’ natural resiliency was coming out.”
In line with a larger overall trend in Northern California, Fishman says he also has been trying to fine-tune the weight and concentration of the Chardonnay and Pinot Noir produced at each vineyard. If Burgundy’s biggest challenge historically has been to achieve even ripeness vintage to vintage, California’s problem cultivating Pinot Noir and Chardonnay been quite the opposite: how to tame abundant sunshine and control vigour resulting from warm days and fertile soils. While the fog assists with this task, one unexpected benefit of the winery’s intensive focus on farming, Fishman explains, is that the vines are more in balance. “It’s on the subtle side,” he says, “but our wine chemistry is looking better too – higher acidity and more flavour at lower sugars.” Opulence has given way to restraint and nuance.
The resulting range of wines at Donum is an impressive display of small-lot vinification, broken down not just by appellation or vineyard, but also often by individual blocks. In 2021, the winery produced six distinct Chardonnays and 17 Pinot Noirs in total from Carneros, the Russian River Valley and the Anderson Valley. With the development of their newest vineyard on the Sonoma Coast, Donum’s already complex patchwork quilt of wines is about to get even bigger.
With a gentle hand in both the vineyard and winery, Fishman hopes to highlight the most minute of variations in each wine, allowing the innate characteristics of each site to shine through. “We have a really intense focus on vineyard flavour first,” he explains.
“We’re not trying to force a house style, just let the vineyard or block do the talking,” Fishman continues, “We’re trying to make the best Pinot Noir and Chardonnay in California, wherever that comes from.” With access to such an extensive assortment of prime locations, now including the illustrious Savoy Vineyard as a feather in its proverbial cap, to say that the future at Donum is exciting is an understatement indeed. While many may think of California Pinot Noir and Chardonnay as one group of wines, a monolith with little variation in style, Fishman and his team at Donum hope to change that mindset, one vineyard at a time.
