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.  The Donum wines have historically been available only to those on their mailing list, but we are now working directly with the estate: browse all current Donum listings.

Discovering Donum’s single-site wines

First place: Donum

Chris Phelps never really meant to start his own winery. But fate had other plans.  Wine had always been part of life, just in the background. Growing up in Livermore, east of San Francisco, Phelps’s parents would buy a ton of grapes from Napa or Sonoma, and make wine each year for themselves. Phelps even dug out a cellar by hand for them as a teenager. Nevertheless, when he set off for UC Davis, it wasn’t to study wine, but medicine. To pay for university, he took a job as a firefighter in Idaho (“kind of scary but super fun,” he tells me). By chance, he met a wine-geek friend, one who eventually convinced him to switch from pre-med to oenology. At Davis, he happened upon Alain Bertrand – one of the first scientists to use gas chromatography to delineate the different aromatic compounds in wine. The Frenchman didn’t speak much English, and Phelps spoke French – so they ended up becoming friends. Bertrand suggested Phelps attend the University of Bordeaux for a year after graduation. There, Phelps tells me, everything “started to fall into place”. Until then, wine had been intellectually interesting – but, during his time in France, it became much more.   There, another professor pushed him to apply for an internship – just in time for the 1982 harvest, a vintage that would turn out to be legendary. He already had offers from both Ch. Simon (Barsac) and Ch. Beauregard, but then was given the opportunity to interview with JP Moueix (of Pétrus). Unusually Christian Moueix insisted on joining the interview himself, alongside winemaker Jean-Claude Berrouet, and promptly gave him the job. The confident young American, however, said he’d think about it – and set off for a holiday in the south of France with his fiancée. Little did he know that Moueix had just bought a swathe of vineyard in Napa – and was planning for the future.  A few weeks later, Phelps was in Nice and bought three postcards from the Chagall museum – ready to make his decision about the three possible roads that lay ahead of him. He decided to take the position at Moueix, posted his rejections and acceptance, and carried on with his holiday. But, as harvesttime approached, Phelps hadn’t heard anything back. He called Berrouet – only to find out that the French postal service had let him down, and the job at Pétrus had been given to someone else. It seemed like his luck had run out, but Berrouet said he might have another idea and would call him back in a few days.   While Berrouet couldn’t offer him anything as prestigious as Pétrus, he found Phelps a job at Ch. des Laurets in Puisseguin-Saint-Emilion – but he wouldn’t just be an intern, he’d be running everything. It was, Phelps said, a “trial by fire”, especially given his only hands-on experience to date had been six months at Louis Martini. He worked non-stop with just one cellar hand to help during the day, and managed to make it through the season.   When the wines were safely in barrel, he went to dinner at Christian Moueix’s house – where, sipping Champagne in the library, Moueix told Phelps about his plans for his Napa project, Dominus – and asked if he’d be the winemaker. “Of course, I said no,” Phelps tells me – recalling how the Frenchman opposite visibly sputtered at the American’s cheek (again). Phelps said he needed more money to live in Napa (and support his bride-to-be) – and more experience. Amazingly, Moueix agreed to let him start from 1984, given the 1983 vintage was set to be just a handful of experimental barrels, and to a pay rise. Off Phelps went, working around California and wintering at Pétrus before returning to lead the team at Dominus.   “We figured it out as we went along,” Phelps says, looking back on the early days of what is now one of Napa’s most prestigious estates. Today they might have the iconic Herzog & De Meuron winery, but things were much more rustic at the beginning – with a small team and little infrastructure. Phelps eventually moved on, joining Caymus in 1996 – but it’s what started happening after-hours, around his day job, that is interesting.  In 1990, Phelps met Larry Bettinelli at a Christian men’s retreat, and hit it off. It was only when they met up for lunch later that they realised they were both in the wine business, with Bettinelli a fifth-generation farmer who was growing grapes. Bettinelli wanted his vineyards to be the best in the valley – but he needed feedback on the fruit so that he could adapt his viticulture. He and Phelps hatched a plan: each year, Bettinelli would give Phelps a ton of fruit, trialling different clones, rootstocks, vine spacing and trellising, harvest methods, and Phelps would make a wine with it. The project was purely intellectual, so the two families drunk the wine themselves, and it also started being used as the altar wine at Phelps’s church (a much higher-grade communion offering than most). For two decades, they kept making tiny batches of their first-class “homebrew”, and Bettinelli became one of the valley’s best growers, working with an increasing number of sites around Napa.  Destiny seemed to abandon all subtlety in 2005. Phelps was hiking through the Sierra Nevada, leading a Scouts expedition, when they were struck by lightning. Two of the group died and Phelps was knocked unconscious. Unsurprisingly, it shook Phelps to the core. “Life is our most precious gift,” he says, “and if we use wine appropriately, it can enhance our lives.”  Two years later, Phelps was on top of a tank that had just been filled with crushed fruit from a relatively new Bettinelli site – and the smell was intoxicating. Following pure impulse, Phelps asked if he could – rather unconventionally – buy the tank’s contents, and Bettinelli said yes. Ad Vivum – inspired by the Latin “vinum” for wine and “vivere” to live, combined with “ad” which translates as “to” or “towards” – was born.  The vineyard was Sleeping Lady (previously Reese), the southernmost vineyard in Yountville, at the foot of the Mayacamas and on the southern end of the valley’s famous bench. There’s a flow of underground water that feeds a creek, with sufficient clay under the gravel and sand to retain water during the dry summer – and has, in Phelps’s words, a “beautiful ability” to self-regulate. Various other producers work with the vineyard, but his two blocks (representing a mere 1.5 acres) are right at the top of the vineyard, below a steep slope that aids the flow of cool air through the site at night. For him there was something special about these plots – producing fruit and wine with what Phelps describes as a “grace note”; it’s a whisper of something that takes the wine to the next level.  In a good year, production for Ad Vivum is 450 cases – but Phelps isn’t looking to grow. He makes one wine, from one site – and that’s the way he wants it to be. The wine is undoubtedly informed by his Franco-American roots, with an elegance, freshness and savoury structure that complements the plush Napa style. As he says, “I try to build wines that speak for themselves.”  Phelps’s – and Ad Vivum’s – story is one of happenstance. Or is it? With a man as devout as Phelps, it seems hard for anyone to believe it’s all an accident – and as Phelps himself says, looking back, it feels perhaps like it’s all part of a master plan.  Contact your Account Manager to find out more about the 2019 release of Ad Vivum or read more about California

“C’est quoi, traditionnel, aujourd’hui?” Marion Raphet half-jokes as we talk about the 2019 vintage, tasting her family’s bottlings at Domaine Gérard Raphet. Since 2011, it feels like Burgundy’s vignerons have been on a rollercoaster: with hail (2012, 2013, 2014 and 2016), heatwaves (2018, 2012), frost (2016 and 2017 for Chablis) and even the influx of Drosophila suzukii – an Asian fruit fly – after a particularly mild winter (2014). While global warming is nothing new to farmers – in Burgundy or elsewhere, 2019 feels like it marks a shift, with the threat of climate change suddenly all the more tangible. The year was full of extremes, from an unusual hard frost in April to a hot, dry season that really challenged vines – and growers. But in a region where tradition reigns supreme, where the way in which producers farm their vines and make their wines is passed down from generation to generation, evolution is now imperative – and, as Mickaël Haratyk of Domaine Joblot lamented, “Some producers don’t change.”  Harvest dates have gradually been creeping back, and – as Frédéric Weber at Bouchard explained – “It’s more and more difficult to pick a good date.” In 2020, Burgundy saw some of the earliest harvest dates on record – often extremely similar to those of 2003. Joseph Colin pointed out, however, that August harvests aren’t new – in 1553 producers started picking in Meursault on 14th August. He argues that the region has always had periods of warm weather that lasted 20 to 30 years; it’s a cycle. The question, however, is how long the cycle lasts – and whether growers or the vines can make great wine with fruit that is picked on 1st August. Haratyk echoed this sentiment, noting that harvests today are a month earlier than 25 years ago; with that pace of climate change, it’s hard to imagine what things will be like in another 25 years’ time.  The focus for growers used to be on getting enough sugar ripeness, with chaptalisation almost rote in decades of yore, but now it’s about retaining balance in the wines. The decision of when to pick is driven by acidity levels, to retain the essential freshness and elegance that defines fine Burgundy as we know it. At Joblot, there was a time when 11.5% potential alcohol equated to fruit that was ready for picking; now it is naturally never less than 14%. They know they’ll have the necessary sugars and maturity (with phenolic ripeness achieved easily), the challenge is to make sure nature’s generosity is off-set by the requisite acidity. But what else are the region’s vignerons doing to adapt to a new, warmer Burgundy? In the vineyard, producers can look at how they manage between the rows: ploughing is increasingly avoided, as it releases valuable moisture from the soils. The use of cover crops is another consideration; while they can help avoid erosion and preserve top soil on slopes, they also present a rival for precious nutrients and water. Growers can delay pruning, which in turn can delay budburst, helping to limit the impact of frost on the vines. Something that many producers emphasise is the importance of a thicker, taller and leafier canopy. While once vines would have been trimmed neatly, and leaves stripped to allow the sun to reach the grapes and aid ripening, today producers are limiting this work, wanting to shield grapes from the heat and limit their exposure. Charles van Canneyt, for example, still trims his vines, but lets them grow higher than he used to, and doesn’t leaf-strip at all. At Joblot, they work with a thicker canopy these days, and let the lateral shoots – that previously they’d have trimmed – grow freely. However, a thicker canopy brings its own potential problems, as Philippe Jouan noted, explaining that oidium (powdery mildew) is now the biggest issue in the vineyard. A thicker canopy means less airflow, creating a more humid environment within the canopy and therefore disease pressure. Many producers believe that mature vines are key – their deeper root systems able to reach water reserves, and with age are thought to gain a natural stability, enabling them to withstand more extreme temperatures. Marion Raphet (Domaine Gérard Raphet) explained how her old vines were so much more resistant to the rising temperatures; noting that even in a year as hot as 2020, the old vines were still green when we visited in mid-October. But some producers have seen old vines struggle in the dry conditions of 2019 and 2020. Benoît Stelhy at Georges Lignier, a proud proponent of permanent grass grown between his vines, saw his old vines seriously impacted by water stress, with the resulting yields so unviably low that they have made him seriously question the way he is working. He is now wondering if perhaps having intra-row grass cover is more important in young vineyards, where their natural vigour needs to be countered by competition. In the winery, there are plenty of benefits to the riper fruit: there’s no need for chaptalisation, and it is in general easier to extract colour, tannin and flavour. However, that same ripeness and the associated lower acidity levels, can pose problems. As Chantal Tortochot explained this year, above 13% alcohol, natural yeasts can struggle – meaning that we may see more commercial yeast (which can guarantee wines ferment to dryness) in use.  The higher pH of these musts also increases the risks of bacterial spoilage, hence producers need to be particularly careful handling them – with hygiene, temperature control and/or the careful use of sulphur of increasing importance. Benoît Stelhy described how he is trying to recreate the cold of yesteryear’s winters; he cools his wines before putting them into barrel, therefore delaying the onset of malolactic fermentation (as the region’s cool temperatures would naturally have done after an October harvest). By doing so, he can avoid adding sulphites at this stage, feeling the wines can therefore benefit more from micro-oxygenation in barrel, before malolactic fermentation takes place when the wines naturally warm up in the spring. But these measures will only work in the short-term; as the region warms further, producers need to start looking further ahead. Re-planting vineyards with rootstocks better suited to today’s climate is likely to be necessary (not to mention considering other issues posed by current rootstock selections). “The vines that are in their prime today,” William Kelley explains, “were planted with a view to early ripening in a marginal climate; in much warmer conditions, the choices of rootstock and vine genetics made in the 1970s, 1980s and 1990s – even by producers aspiring to high quality – are close to the opposite of what’s required today.” Such a shift, of course, takes time – with the need to leave vineyards fallow between re-planting for several years, and a minimum three-year wait for vines to produce fruit, or longer for fruit of serious quality. Experimental plantings of Syrah and Malbec in the region feel a little ahead of the curve, but there will certainly be a need to adapt clonal selections. The rise in the popularity of Aligoté – frost-resistant, early-ripening and high-acid – is no coincidence, and some suggest that it could be a solution for retaining freshness in the region’s whites. Small percentages of Aligoté and Pinot Blanc were once planted amongst the Chardonnay in even the grandest of Crus, and it’s something William Kelley would like to see make a comeback, feeling it “would help white Burgundies retain the tension and acidity we prize so highly”. As the mercury rises, we’re already seeing a shift in the sites that thrive. Until now, many of the sites considered the “best” are mid-slope with good exposure and drainage, basking in the sun, often with relatively little topsoil; increasingly this simply isn’t what is needed in the climate. “The big winners are places such as the Hautes-Côtes,” Kelley explains, “which are today enjoying a climate that’s very similar to what the Côte de Beaune and Côte de Nuits experienced in the 1990s.” Gros Frère & Soeur has even planted a plot of Pinot Noir at the very top of the Côte, beyond the limits of the Burgundy appellation, at altitudes that would once have been impossible.  Plots that were once unviable now are, and sites previously deemed “lesser” for their cool, marginal temperatures are being favoured. Similarly, sites with deeper, more clay-rich soils, with greater waterholding capacity, are becoming more desirable with drier conditions. As Benoît Stelhy noted in 2019 and 2020, Clos Saint-Denis with its poor soils struggled more than, say, Clos de la Roche. Alvina Pernot noted that two of her parcels either on the edge of or in the middle of forested areas (Meursault Premier Cru La Pièce sous le Bois and Puligny-Montrachet Premier Cru Clos de la Garenne) are shielded from the sun, preserving acidity and freshness in the wines. The long-term viability of some sites, however, is hanging in the balance. Producers are increasingly aware of the threat that climate change poses. As Charles van Canneyt explained, at the moment they are only seeing the benefits – with riper fruit and more concentrated musts – but they’ll need to learn how to handle, and battle, the negatives too. While the future might be uncertain, producers are slowly but surely adapting. As Benoît Stelhy noted when discussing the benefits of organics, it’ll do for now – but does it give an answer for tomorrow? “We have to go further,” he said, a sense of urgency in his voice. It’s a call to arms, and one that producers will have to follow. For now at least, the wines are arguably better than ever; let’s hope that will long be the case.
