Oak barrels have been used in winemaking for thousands of years. While initially their purpose was simply as a holding vessel, today it is much more than this. As we have learnt about wine production at a molecular level, we have discovered the unique interaction between oak and wine – adding flavour, textural complexity and increased ageing potential. These intrinsic qualities have seen oak at the forefront of fine wine’s greatest success stories – but also some of its greatest failures. The use of oak to improve a wine requires great skill and finding that balance has shaped the modern history of fine wine.  What is rather beautiful about winemaking, particularly in fine wine circles, is that despite the input from developments in science and technology, production remains an artisan craft, relying both on tradition and technology. The barrel-maker is a perfect example of this partnership and no one understands this better than François Frères. This lauded Burgundy cooper’s ties to the world’s greatest wines make it one of a very small number that have lived through the development and fashions within fine wine.  Today, business has never been better for François Frères; they produce 30,000 barrels a year and export to every major wine region in the world. The secret to the François Frères barrels historically, Gigandet believes, is their consistency, while the all-important signature toasting is paramount. To keep up with the ever-growing world of fine wine, François Frères produces tailor-made barrels that fit the varying climates and varying styles of each winemaker, meeting the standards set by today’s precision-led winemaking. Despite the growth of the business in recent years, François Frères still remains intrinsically linked to its homeland in Burgundy and the specific microclimate of Saint-Romain that is so important for the seasoning of their oak – another key factor behind the company’s success. “The microclimate of Saint-Romain, in a windy and pollution-free environment is ideal for the seasoning and drying of the oak. This oxidation of phenolic compounds under the influence of fungi, releases enzymes that hydrolyse the phenolic compounds, reducing the wood’s astringency, producing oak of the finest quality for wine production,” Gigandet tells me. The art of the cooper is much more than just sawing and toasting – it’s about sourcing, traceability, control of drying time and heating, hygiene, temperature control, sorting and more. With increased knowledge, the quality of the barrels, like that of the wines, has greatly improved. Even just a few years ago, Gigandet admits that in colder Burgundy vintages, sometimes their barrels jarred with the wine – they “brought too much tension and could sometimes seem too austere”. But now they have a better understanding of the qualities their barrels can bring to Burgundy: “François Frères barrels remain attractive to winemakers because they are great at retaining freshness and minerality.” Perhaps most importantly, François Frères wants its barrels to amplify a wine’s intrinsic qualities. “It wants to accentuate the beautiful tannic structure of a wine, contribute to its flavour but without excess of sweetness from the toasting, as well as amplifying the wine's tension and minerality, helping retain its freshness and its fruit,” Gigandet says. As technology has developed, so has François Frères. It is what Gigandet aptly calls “the evolution of taste” – “the cask has evolved considerably over the last few decades along with the quality of the wines. Today, the barrel is much more specific, manufacturing almost tailor-made barrels for each customer’s needs.” The business was founded by Joseph François in the early 1900s, never imagining that being a cooper would become a full-time job. Back then, Gigandet reminds us, “It took several trades to live.” But the next generation, Robert and Henri François, saw the demand for oak casks rise, at that time mainly used to transport wines. They took the operation full-time, creating the François Frères brand in 1942. In those days, as Gigandet points out, “The tradition of maturing wines in barrels was reserved only for the very top red and white wines of Burgundy and the great Bordeaux châeaux.” Even within these regions, barrels were a luxury, re-used year after year given their expense, therefore keeping the demand for new barrels low. By the 1960s the brothers were met by the development of stainless steel and plastic containers. The barrel quickly lost it supremacy as the preferred vessel for transportation and demand plummeted. It was only the top producers that helped keep the cooperage going. By the 1970s François Frères was producing barrels for one of the world’s most famous estates, Domaine de la Romanée-Conti – a partnership that would be instrumental in the continuation of the business through a difficult period. The next generation – Robert's son, Jean – was confronted by the economic downturn of the early 1970s and turned to export to save the family business. Fortuitously at this time, oenologists in the United States started to highlight how ageing wines in new oak barrels brought complementary flavours and complexity to the wines. In the 1980s, the French market caught onto the idea and both export and domestic markets grew. The oak barrel was entering an era where it would become the star of the show – and a must for all top producers. François Frères’s reputation for working with the best saw it perfectly placed to capitalise on this new-found love for the barrel. But according to Gigandet, it wasn’t just the fashion of using new oak in the 1980s and ’90s that saw such a huge increase in demand. This trend emerged just as wine exports exploded. What he calls “the democratisation of wine” saw the world of wine suddenly open up to the middle classes – and this increase in sales saw an ever-increasing need to maintain quality and improve consistency. Such demand prompted and funded a better scientific and technological understanding of wine production. More importantly for François Frères, it fuelled the need for a better understanding of what barrel-ageing does to wine – and why. It was already clear that contact with new oak changed wine profoundly. Most obviously the aromas and flavours of the wine develop, becoming more complex. These aromas and flavours are formed during the toasting of the barrels. “It is this toasting of the barrel that remains the signature of the cooper,” explains Gigandet. But the oak didn’t just impact the flavour, they came to understand that, being porous, oak allowed the wine to undergo “controlled oxygenation”. The exchange of air through the oak staves, in particular for red wines, helps stabilise the colour and polymerise the tannins. This polymerisation not only softens the wine, but brings a textural complexity, a millefeuille layering of mouth-feel brought about by the linking of long tannin chains, encouraged by the micro-oxygenation process that the wine goes through when aged in oak barrel. “François Frères barrels are ageing tools, which contribute to the textural improvement of wines, when used wisely,” Gigandet explains. As the wine world’s love of oak grew, François Frères’ main export customers went from little-known names to pioneers in their respective regions – with Robert Mondavi in the US, Angelo Gaja in Italy, Nicolas Catena in Argentina and Australia’s Rosemount winery. Each of these producers further cemented the cooper’s reputation, representing the very pinnacle of oak barrel production. Of course, like all fashions, the oak craze of the ’90s saw some extreme uses – 200% new oak ageing or an over-reliance on oak to provide flavour to wines that lacked the natural concentration to carry it. This saw many producers and consumers react strongly against its presence in wine at all. Even Gigandet admits that there are wines with “excess woodiness” to their detriment. Today, the barrel also has to compete with new trends in wine maturation – concrete eggs and clay amphorae, for instance. But while these new vessels have captured the imagination of the world’s top winemakers, it is not necessarily at the expense of the barrel. “The barrel has an important oenological role in the development of wines from certain grape varieties,” states Gigandet – notably Cabernet Sauvignon, Merlot, Syrah and Pinot Noir. But he also outlines how different ageing vessels combined can also benefit a wine’s potential for complexity. This is certainly the case amongst some leading producers in Bordeaux and Burgundy that are using both oak barrels and alternative ageing vessels. Coopers like François Frères have weathered the changing relationship wine has had with the barrel; with shifting views of critics and drinkers over the last century. Fortunately for fine wine lovers, there’s little sign of oak fading into the background. Oak remains a vital ingredient in many of the world’s greatest wines, adding to its flavour, textural complexity and – of course – ageing potential. Today oak has never been so deftly handled, bringing so much to a wine, while retaining the grapes’ natural expression. The art of the cooper lives on. Read more Editorial

François Frères on the art of the cooper

Finding the balance: the art of the cooper

It was the vision of Jacques Perrin in particular – who farmed the property organically from 1950 onwards – that cemented Châteauneuf-du-Pape’s Château de Beaucastel reputation. Today his sons – Jean-Pierre and François – are at the helm, with fifth-generation Marc, Pierre, Thomas, Cécile (Jean-Pierre’s children) and Charles, Mathieu and César (sons of François) also all work full-time at the estate. All seven of the children worked in wineries around the world before returning to the family estate.  A visionary estate The estate was one of the first in Southern Rhône to become organic (in 1950) and then biodynamic (in 1974), making the vineyard better prepared than most for the climate change effects over the last 30 years.  “Beaucastel is the largest Châteauneuf-du-Pape estate in one contiguous plot and it stands at the most northern limit of the appellation. It is a vineyard which is therefore very exposed to the Mistral winds, which has a huge cooling-down effect,” Emmanuel explains, protecting the vineyard from extreme temperatures.  The vineyard is based on a limestone bench covered by a rather atypical mix of clay and sand, topped with diluvium “galets roulés” (pudding stones). It is an incredible terroir that, Emmanuel explains, “allows us to combine power and finesse even in the driest vintages. It has always been considered a benchmark terroir in the area and was in fact a cru before the Châteauneuf appellation was created.”  
The biodynamically farmed old vines have also helped offset the ever-increasing drought pressures in the region. “We are extremely fortunate to have older vines,” Emmanuel says. “The galet roulés covering our vineyards also help prevent water evaporation. So all in all we’ve managed to make great wines even in warmest and driest vintages.” That hasn’t stopped the domaine, however, from continuing to adapt their methods to better cope with the ever-present threat of climate change. “We are learning more and more every year and continue to implement changes we deem necessary.” Alcohol levels in the region have undoubtedly risen, an effect that the estate looks to counter. 
When Jacques Perrin was in charge, he created a very specific vinification technique which he later patented. He would heat up the must to 80˚C, to start fermentation quickly while allowing Jacques to use less Sulphur, helping fix the colour of the wine, particularly with the Mourvèdre grape which has a tendency to lose colour with age. But this method also reduced the greener flavours in the wine, that came from less ripe grapes. 
Today’s climate, however, does not face the same issues, with consistently riper fruit. As a result François and César have phased out this technique, instead opting to whole-berry fermentation, and even whole-cluster ferments for varieties like Syrah, to naturally reduce alcohol levels. These days they also pick earlier, opting for more freshness whereas in the past it was always the goal to maximise ripeness, something that no longer is an issue for the region.  “The estate is always looking at ways to counter the issues of climate change,” Emmanuel continues. “For example, some of the younger Syrah vines are today producing very powerful wines so we are either co-ferment with some Grenache, reincorporating some of the stems in the vat or carry out whole-cluster fermenting,” helping to find better balance in
the wines. In the vineyard too, the team is constantly looking for ways to improve. “We recently tried spraying clay on leaves to limit photosynthesis,” Emmanuel says. The initial experiments have proved positive, but it is still too early to see the long-term effects on the wine
and requires further testing. 
But this experimental approach is everywhere in the property. They continuously make alternate blends that they age in the Beaucastel cellar and over time compare with their main cuvées to see how well the final blend develops versus a different potential version of
the same wine: Emmanuel states the cellars are full of these experiments. 
The domaine has also been assessing how the Beaucastel wines age with different fining techniques. “We do a lot of comparative tastings and assessing of older experimentations. For example, we recently did a horizontal of Château de Beaucastel 1996, where each bottle was fined differently, and identified which fining technique works best for ageing the wine – this is crucial in the development of our knowledge and helps us to make sure decisions taken in the moment are the best ones for the future.” 
Hommage à Jacques Perrin What is distinctive about Château de Beaucastel and the Hommage cuvée in particular is the high proportion of Mourvèdre in the blend. The Hommage is typically made up of 60% Mourvèdre. Emmanuel explains, “Hommage is from our Courrieux lieu-dit parcel, where Mourvèdre was first replanted (post-phylloxera) in 1910. As Mourvèdre is such a late-ripening
varietal, Château de Beaucastel needs an outstanding Indian summer to hope for an Hommage vintage. The decision thereafter is taken during the blending tastings. 
“When tasting the foudre of Courrieux back in 1989, François and Jean-Pierre were overwhelmed by the outstanding quality and knew that it had to be bottled on its own. Jacques Perrin’s intuition for the best blend from the estate revolved around a dominant proportion of Mourvèdre. As a tribute to their visionary father, they followed his instinct and
dedicated this unique cuvée to him.”  Production remains tiny despite the huge demand for the wine. In recent vintages, production has been around 6,000 bottles per year. The only difference in the vinification process of Hommage versus their other cuvées is an extra six months’ ageing in 4,000-litre foudres. All the winemaking is fairly hands-off, vinifying all the varieties separately apart from the Muscardin, Vaccarèse and Terret Noir which – due to the tiny quantities – are co-fermented. The reductive varieties – Syrah and Mourvèdre – are fermented in open-top wood fermenters and the remaining oxidative varieties are fermented in concrete tanks prior to the all-important blending sessions with the family.  The 2018 vintage has already been fantastically reviewed, awarded a potential perfect 100 points from the Wine Advocate, with reviewer Joe Czerwinski describing it as “full-bodied
but incredibly silky, combining great purity, richness and length into a seamless, elegant package that should give immense pleasure for decades to come.” The success of the 2018 vintage, according to Emmanuel, was “down to the perfect ripening conditions in mid-October, allowing them to bring the grapes of this late-ripening variety in at perfect maturity – 2018 was fantastic for Mourvèdre.” 
The grapes of the Southern Rhône 
Château de Beaucastel proudly uses all 13 permitted varieties of the Châteauneuf-du-Pape appellation. Some even say 18 varieties, since varieties like Grenache, Terret, Clairette and Piquepoul all have a black, pink and grey clone of the variety mixed within the vineyards. “Each variety brings its own attributes that differ depending on the vintage, but also depending on the amount you use or the blend you make,” says Emmanuel. “For example, when you open a young Beaucastel, it’s very Grenache-driven, even when there is a similar percentage of Mourvèdre. It’s only few years later that Mourvèdre will finally come to the
fore, revealing game, leather and savoury characteristics. “Individually, Mourvèdre brings power and structure, but when you open an older Beaucastel it delivers freshness and silkiness. Grenache Noir brings kirsch, plum and cassis fruitiness. Syrah adds color, tannin and spices, and when blended with Mourvèdre and Grenache it
brings truffle notes.  Counoise can be considered the Pinot Noir of Châteauneuf-du-Pape and has a distinctive white pepper note. Cinsault adds freshness, Muscardin and Vaccarèse are very floral and add freshness, Terret Noir is light even in colour and adds acidity. The white varieties of Roussanne and Grenache Blanc bring elegance and freshness. Clairette is very aromatic and brings unctuosity. Bourboulenc adds tension with notes of almond and vanilla, Piquepoul richness and Picardan adds a lot of bouquet.   “For us it is very important to have all the varieties to make an elegant and balanced wine. However, above all, it is the knowledge and the art of blending, passed on from generation to generation of the Perrin family, that is the key to understanding the real expression of Château de Beaucastel terroir.” With experimentation at the heart of the Perrin philosophy, the infinite potential of blends when using so many grapes in the wine keeps the extended Perrin family busy monitoring their blending decisions as the wines develop with age. With the 2018 Hommage, it looks like
all their experimentation is paying off. Explore all current Château de Beaucastel listings or browse more Editorial 

Châteauneuf-du-Pape’s Château de Beaucastel dates back to the 16th century, but it was only after the Perrin family took control of the estate in the early 1900s that it became one of the most iconic and well-respected wine producers in the Southern Rhône.
