Napa’s producers have already started releasing their 2021s – and more will be hitting the market in the coming months. The vintage is one that allowed producers to breathe – and produced some stunning wines, as Rachael Ryan – Senior Buyer at Vinfolio – discovers
After the stresses of 2020 – with severe drought, heat and widespread wildfires, the 2021 vintage provided much-needed relief for Napa’s wine producers. Not only was the growing season reassuringly uneventful, but the resulting wines are fantastic. Concentrated, pure with vibrant acidity, this is a vintage that sits alongside 2013, 2018 and 2019 – the best in recent years.
“I’m very happy to move on from talking about 2020! It was stressful to go through and stressful to relive,” said Maya Dalla Valle, winemaker at the eponymous estate founded her parents. Most winemakers and vineyard managers held their breath as the 2021 season progressed, anxious about the potential return of hazardous wildfires that increasingly seem to be the new normal in Northern California, but the danger never materialized.
The most significant factor influencing the 2021 harvest was instead drought, which unfortunately entered a second year. Conditions were exceedingly dry – historically so, says Chris Phelps of Ad Vivum, who noted that it was one of the driest years he can remember.
Napa’s Mediterranean climate dictates that nearly all precipitation falls during the months of October-March, and the rains generally begin in the weeks following the close of each harvest, but this didn’t happen in 2020. While early winter was quite cold, helping to push the vines into dormancy, but rain didn’t arrive until January, February and March 2021. With around seven inches measured in Oakville, this was significantly lower than normal and far less than the total amount needed to reinvigorate the roots and replenish the water table.

Access to water, either from precision irrigation, or the benefit of a location with good water supply, therefore, was critical to shoot growth and canopy development. Sleeping Lady Vineyard in southern Yountville – the fruit from which Ad Vivum is crafted – backs up against the Mayacamas Mountains that form the western edge of Napa Valley. Here, natural springs funnel moisture down to the vineyard. In other locations, such as the eastern hillsides of the valley, long sunlight hours and faster-draining soils presented a greater challenge. The solution at Dalla Valle was to begin irrigation much earlier than normal, and at a greater volume, in order to mimic the rainfall that didn’t happen naturally.
Although 2021’s growing season was quite warm, it was cooler than 2020 and, importantly, there were very few heat waves – and those that did take place were mercifully short. The first of these spikes, where the daily temperature reached over 100˚ Fahrenheit, occurred in mid-June, a point early enough in the growing season where its impact was negligible. The remainder of the summer was consistently warm, with little variation, up until late August and early September, when the valley saw two minor heat spikes.
The diurnal swing that Napa is known for, with nights quickly cooling down after sunset, was also in full effect in 2021, helping to preserve the grapes’ natural acidity. Given the steady weather and lack of wildfire risk, winemakers had the luxury of time when deciding to pick. For most, harvest began in the first two weeks of September – slightly earlier than average, but not drastically so.

The year’s dry conditions reduced yields, which was not surprising, though “sometimes harrowing” as Andy Erickson (of Favia, and star consultant winemaker) described. The resulting clusters were lighter than normal, comprised of small berries with thick skins. While Phelps reported that the yields at Ad Vivum were down by 15%, he emphasizes the positives that have emerged from these small, compact clusters: “The color is extraordinary, with higher than normal levels of anthocyanins due to the long, slow ripening.” Others reported an even more drastic reduction in yield – up to 30% in some locations – though variation depends on not just access to water, but also soil type and depth. Vine age can also help mitigate drought conditions. Lisa Togni of Philip Togni Vineyard, perched at nearly 2,000 feet at the top of Spring Mountain, said that her yields were more or less normal, something she credits to the 32-year average age of her vines, which, remarkably, have never been irrigated. She feels that her vines’ well-established roots are able to reach deeper and access more water than younger vines.
The low yields also sparked some wineries to change course in the vineyard prior to harvest, in regard to both shoot thinning and dropping fruit. Opus One made the decision to halt their green harvest. This process – during which a certain number of clusters per vine are removed, lowers yield and increases the intensity of the remaining fruit while also eliminating any slightly under- or over-ripe clusters – was always standard for Opus One, as it is for many wineries in Napa. This decision to change course was an easy one to make in a year like 2021, winemaker Michael Silacci said, and he is thrilled with the results, describing “more of a range of ripeness, with more layers and texture, and more vineyard character” in the final wine.
Napa’s prized To Kalon vineyard
In the winery, tannin management was crucial. With a reduced skin-to-juice ratio, it was important to handle the fruit gently. For Tony Biagi, winemaker at several Napa Valley wineries, including Hourglass, Amici, The Vineyardist and To Kalon Vineyard Co, the main puzzle was how to coax color from the fruit, while avoiding over-extraction of the tannins. “We were meticulous in how we macerated; we shortened the window,” he explained. Biagi said that the firm tannins are reminiscent of 2013, though perhaps not quite as muscular, as the more stable weather of 2021 allowed “more time to buff the edges”. At Dalla Valle, the decision was made to leave the wines in barrel for an additional two months because they displayed so much power and concentration.
Despite the smaller berries and low yields, the condition of the fruit was described as nearly perfect by everyone. Low disease pressure and the lack of heat spikes produced uniformly healthy, good-looking clusters. Silacci recalls perhaps the most worrying moment of the 2021 harvest at Opus One, when their optical sorter broke down just as the fruit began arriving at the winery. Fortunately, however, the quality of the fruit made a stressful moment less so: “If ever there was a vintage we didn’t need a sorter it was 2021!”
Early impressions of the final wines are uniformly positive – glowing with praise, even – and not simply because the year was a welcome relief following the trials of 2020. As we found in our tastings, the wines offer concentration and intensity with real purity of fruit, all balanced by refreshing and somewhat surprising acidity – allowing them to age beautifully.
Ad Vivum’s Chris Phelps
Phelps noted that the 2021s remind him of 2016, 2018 and 2019, all vintages with “great concentration, tension and generosity”. For Biagi, the vintage instead portends a new direction for the region, while referencing other hallmark great vintages of the past. “For me, the 2021s are classically Napa Valley. They are not crazy ripe, and you get a sense of the new style Napa is moving towards, with both power and freshness,” he opined. But perhaps Togni summarises the year most simply: “2021 was the kind of vintage we hope for every year.”
Napa 2021 in brief:
- The growing season was – especially after 2020 – refreshingly uneventful
- The wines offer both concentration and freshness
- Dry and warm, but not overly hot, conditions reduced yields, with up to 30% less fruit at some addresses – and a crop of small, thick-skinned berries
- Rich yet vibrant, the wines are set to age very well
- A vintage to rival 2013, 2018 and 2019 in quality
