In an era where minimal intervention is so applauded, discussing the art, skill and work of a winemaker can be unfashionable. Producers can seem keen to gloss over or shy away from discussing the tricks of their trade. And tricks there undoubtedly are – as vintages like 2021 prove.  Jean-Antoine Chaptal was a man of many talents. Working in the late 18th and early 19th centuries, he was a scientist and statesman whose interests varied from sugar beets to gunpowder and merino sheep. For wine-lovers, he has been immortalised thanks to his 1801 paper, L’art de faire, de gouverner et de perfectionner les vins – in which he introduced what we now call “chaptalisation”. It was nothing short of revolutionary.   During fermentation, yeast converts sugar into alcohol and carbon dioxide. Chaptal realised that if you added additional sugar to raw grape juice, you could increase the final alcohol content of the wine. The sugar would, along with the natural sugars from the grapes, be fermented, producing a dry, but stronger wine, and – with alcohol a natural preservative – one that would keep better. Suddenly producers could give wines from cooler years a boost (with the alcohol adding much more than just ethanol). Some winemakers, of course, abused the technique – at one point in the early 20th century, the Languedoc reportedly produced twice as much wine as was feasible for the volume of grapes harvested.  Today the practice is strictly controlled by regulatory bodies, only permitted in cooler regions where it is deemed a useful tool, limited according to region and vintage conditions to protect quality. In marginal climates where ripeness isn’t guaranteed, chaptalisation has been the norm. Although you won’t find them in marketing pamphlets or Instagram feeds, bags of Tate & Lyle are widespread in the cellars of Champagne, Burgundy and England, in particular. It’s one reason why climate change has, for many such regions, been a blessing of sorts – the warmer conditions allowing them to more reliably bring in a crop of sufficiently ripe fruit.    Throughout the 19th century in Bordeaux, wines were often blended with those from warmer climes – the finest had a dose of Hermitage (something which Ch. Palmer pays tribute to today with its Historical XIXth Century Wine), while lesser wines had a dollop of something Spanish. Chaptalisation took over in the 20th century, and was widespread – considered part and parcel of making wine in the region.   Global warming and the technology that has revolutionised viticulture and winemaking in the region has changed that, but 2021, with its frost, mildew and generally cool conditions, saw many of northern Europe’s winemakers forced to chaptalise once more – or at least consider it.  Setting off to taste Bordeaux 2021 en primeur, I was braced for the polished spiel of the world’s grandest estates. But perhaps signalling a broader move towards transparency in the industry, what I found was a refreshing frankness. Not a single producer looked to mask the incredible challenges of the year – and the often unspoken reality of making wine in such conditions.  We asked about the potentially contentious topic at every property we visited, receiving only a small handful of slightly wary responses on the topic (“We did what we had to do,” one winemaker said, with a smile). The vast majority of producers felt it was a necessity in the year, although not everyone agreed.  At Ch. Cheval Blanc, Pierre-Olivier Clouet firmly stated, “We never touch the natural balance of the wine.” That said, they did chaptalise three plots in the end, but none of them made it into the Grand Vin. Delphine Kolasa of Margaux’s Marquis d’Alesme believes that you can almost always feel a warmness from the additional, unnatural alcohol – although she noted a few properties who had managed it so well you could barely tell.  At Les Carmes Haut-Brion, Guillaume Pouthier highlighted the balance needed with the year’s acidity levels. The relative lack of sunshine resulted in grapes high in malic acid, meaning that the malolactic fermentation (where hard, green-apple malic acid is converted into softer lactic acid) had a greater impact in the wines, reducing the overall acidity. With this in mind, he felt that chaptalisation could lead to wines feeling “flat” – but it wasn’t a necessity for him, given he managed to reach 13.5% natural alcohol thanks to the property’s warmer, suburban microclimate. These producers weren’t alone – Beychevelle, Léoville-Poyferré and Lafite-Rothschild all opted to work with what nature gave them.  But there were plenty of outstanding estates which felt it was an essential element to success in the year. At Le Pin, Jacques Thienpont remarked how they had to employ “forgotten methods”, noting that it was more than 20 years since he’d had cause to chaptalise in Pomerol. He used it on a couple of vats. Joséphine Duffau-Lagarrosse – the young vigneronne who has taken over her family’s estate – joked about having to learn how to do it, so alien is the process to a millennial winemaker. (“I called Burgundy,” she said, laughing mischievously.)  Similarly, Christian Moueix – another of the Right Bank’s old guard – noted how he used it almost every year in the 1970s, but hadn’t needed to for a long time. For him the key was not to overdo it, enough to add a maximum 1% alcohol. There was a clear consensus on this among proponents – adding half or one degree (of alcohol) was beneficial, but if you pushed things too far, you’d lose balance in the wines. That touch of additional alcohol added body, carried flavour and allowed for more extraction.  At Ch. Canon and Ch. Berliquet, they noted that they always pick on phenolic rather than sugar ripeness, but one of the quirks of 2021 was that the skins ripened before the sugar had accumulated to the expected level. They therefore picked and chaptalised to bring the wine up to 13.5%.  Omri Ram – who produced a particularly exquisite flight of 2021s at Ch. Lafleur – emphasised that he wasn’t anti-chaptalisation, but was anti it being popularised. He used it on a handful of parcels (the most humid plots) where he felt they would benefit from just “a little bit more” – with all the wines ending up between 13.4 and 13.6%. Ch. Margaux was notable for highlighting that, at least for them, chaptalisation wasn’t abnormal. They also used it on a couple of plots in 2017, 2019 and 2020.   There’s no doubt that chaptalisation can be done badly. But tasting through the 2021 vintage in Bordeaux, it’s also clear that it can be done well – used seamlessly to produce wines that are better for that spoonful of sugar. If you don’t trust us, check the critical acclaim for some of the wines mentioned above.  Intervention is key to wine – a vigneron’s craft goes beyond the field. The best wines come from carefully farmed vineyards, sites nurtured to produce expressive fruit, but it takes a talented winemaker to translate that into something you can drink. And in a year like 2021, no winemaker should be criticised for using every tool available to them.   Browse all Bordeaux wines or read more Editorial 

Chaptalisation – the addition of sugar to enrich wines – isn’t fashionable but it’s a practice that has long been common (and often essential). The 2021 vintage saw many Bordeaux winemakers turn to the technique; here we dig into exactly what it is – and why it shouldn’t be dismissed 

Chapitalisation became common practice in the cool Bordeaux 2021 vintage. We talk to some of the region's top growers about this controversial technique. 

Chaptalisation and Bordeaux 2021

A spoonful of sugar

For many, the past 12 months meant working in isolation and big plans were shelved. At Domaines Barons de Rothschild (Lafite), it was an extremely proactive year of change. These changes have resulted in the strongest line up of wines from the Lafite stable we can remember. Ch. Duhart-Milon has seen a massive step up in quality with their 2020, and Lafite has reached new levels of ethereal finesse – while their Pomerol property, L’Evangile, has found fantastic freshness and clarity without losing any of its Pomerol opulence. They are a unique line-up of wines, each brimming with personality. As the demands for precision viticulture becomes more established in today’s top-flight Bordeaux, the leading First Growth estates know they must be at the forefront of these changes if they are to maintain their preeminent stature. Ch. Lafite Rothschild and its fellow Domaines Barons de Rothschild (Lafite) estates of L’Evangile, Duhart-Milon and Rieussec are no different. In this dynamic period for Bordeaux such changes and improvements have taken many forms. Perhaps the most visibly apparent development at DBR Lafite is the new winemaking facility for Ch. Duhart-Milon right in the centre of Pauillac’s town centre. It fortunately came into operation just in time for the 2020 vintage.  DBR Lafite’s International Director Jean-Sébastien Philippe believes the exceptional state-of-the-art facility has brought “a new level of precision to the wine”. The introduction of temperature-controlled, smaller vats allows for plot-by-plot fermentation, picking the grapes only at optimum ripeness, rather than lumped all together in one vat. On tasting, it has clearly made a huge impact on the wine, with better ripeness to the tannins. It has really captured the finesse so typical of its bigger sibling Lafite. The clarity of fruit is fantastic and is a big step up for the estate. Perhaps less visible but no less significant is the new team dynamic now operating at the properties, where a heightened level of collaboration has been instilled to better circumnavigate decisions made in the vineyard. Philippe is quick to point out that 2020 was what the French call “un millésime de vignerons”, in that the success or failure of the 2020 vintage lay firmly at the feet of those working in the vineyard. It was a growing season where many difficult decisions had to be made.  The 2020 vintage is in fact Lafite’s first full vintage working organically (and L’Evangile’s third) – no mean feat considering the outburst of mildew that threatened the vineyards in the wet spring. Never has collaboration and specialist know-how been more essential.  “We needed to question ourselves a lot,” admits Philippe, “and no one is right alone... It was a vintage where the vigneron was forced to question themselves every day. It was a vintage of contrast and team spirit. We had to think collectively across the team,” he adds.  It is the first year that the two flagship properties of L’Evangile and Lafite have had two separate dedicated Technical Directors with Eric Kohler remaining in charge of Lafite and Duhart-Milon, while Olivier Trégoat was able to focus on L’Evangile and Rieussec. Beyond the permanent staff at each château, the team was able to make use of a shared research and development team headed up by Manuela Brando. It was Brando’s crucial role to co-ordinate data, empirical research, and lead improvements while working collaboratively with the different teams in the vineyard. Something she has been doing with the Lafite team since 2015. This additional level of research has enabled the teams to make some bold decisions, resulting in some truly impressive wines in 2020. Although Lafite is consistently lower in alcohol than most other Pauillac properties, for the wine to come in at just 12.8% alcohol in what was a dry, hot vintage is staggering. Beyond that, the wine is no less detailed or impactful for it, bringing a level of the ethereal into the Pauillac structure. It is an extraordinary wine – so light on its feet, yet deceptively structured with fantastic depth. There are few estates with the confidence to produce a Pauillac of such finesse, but it remains Lafite’s signature. At L’Evangile, their courage was displayed at harvest. Philippe is proud to admit they were the first property out picking in the vineyards of Pomerol – determined to capture the freshness of the vintage. They had picked 80% of the entire crop prior to the heatwave that hit the Right Bank between 12th and 14th September.  “With the natural richness and maturity of the grapes, we are always looking for freshness and balance,” says Philippe, “always trying to make wines that seem younger the older the wines get.” At L’Evangile, they took another brave step and reduced the cuvaison period from 28 days' maceration on skins down to 21-23 days. This was another way to increase freshness in the wine. They also reduced the new oak to 50% (previously it made up 80%). But the key for Philippe was “to be very precise at assemblage”. “It is important to have as many lots of wines as possible to taste when blending,” he says. “2020 is a vintage which required tough decisions – there was no room for compromise.”  L’Evangile is undoubtedly very special this year. Perhaps even better than 2019, which was already very good. The wine has great generosity, so typical of Pomerol, but is more elegant in 2020. What is so impressive about the wine is its sustain on the palate: it has incredible length, and the clarity of fruit just stays with you right to the finish. Changes are far from over at Domaines Barons de Rothschild (Lafite), as plenty of further experimentation continues behind the scenes. But what is abundantly clear with the 2020 wines is their investment and commitment to collaborative viticulture is setting a precedent amongst the elite of Bordeaux – and the wines have never been more precise.
