This year Michael Silacci is celebrating 21 years at Opus One. Taking over as winemaker for Napa’s first cult estate and arguably the region’s most famous property (a joint venture between Ch. Mouton Rothchild and Robert Mondavi) was no small task. But Silacci’s experience was almost unparalleled; he’d worked in the valley for 40 years, under some of the most iconic producers in the region’s history. In the 1980s, Silacci was mentored by America’s most influential post-Prohibition winemaker, André Tchelistcheff at Beaulieu Vineyard. In the 1990s, he became the right-hand man of Napa legend Warren Winiarski at Stag’s Leap Wine Cellars. When he took the role at Opus One in 2001, he was making wine alongside Mouton’s winemaker Patrick Léon and Robert Mondavi’s son Tim Mondavi. Of all the many things he learnt from these mentors, it was their belief in him that really empowered him – and it was this that would shape his work ethic at Opus. Silacci understood the power of responsibility from a very young age. Working in his grandfather’s dairy farm at the age of 10, he was an essential cog in the operation. “He was a very practical man,” says Silacci of his grandfather, “and would allow me to get on with my work, without ever looking over my shoulder.” Silacci quickly learnt what was expected of him. Silacci found himself in a similar position in his first winemaking job. He had just finished his studies at the University of Bordeaux. While he had worked in wineries and vineyards before, up until that point he had never really been given any responsibility or allowed to make decisions. In a subsequent internship, he found himself under the mentorship of Bordeaux wine legend, Denis Dubourdieu (Ch. Doisy-Daëne), who turned to Silacci and said, “You have taken all the classes, so make the wine!” Dubourdieu instantly put his faith in Silacci’s abilities, which was hugely inspiring for the young winemaker.   It wasn’t long before Silacci was drawn back to the US and Napa where things were really starting to develop; first working at Beaulieu Vineyard, then at Stag’s Leap Wine Cellars. In the 1990s, Silacci witnessed a lot of change in the valley as phylloxera ravaged the region. “First, there was denial, then there was anger and finally we learnt from it,” he says. “If Napa was to survive as a wine-producing region, people had to work together to solve its problems.” The group effort that followed – experimenting with rootstocks and clones, and most importantly sharing their discoveries, seeking the right combination to sustain the region’s future –was inspirational. This was a problem that couldn’t be solved by the individual.  When the opportunity arose to join Opus One in 2001, Silacci leapt at the opportunity – but it wasn’t an easy start. Silacci was used to a hands-on role, working in the vineyard and winery. At Beaulieu Vineyard, he oversaw 28,000 acres, five vineyard management teams, five winemakers and 85 grape growers. Under Tchelistcheff and Winiarski, he had learnt how to read the valley – noting how fruit in the same vineyard changed where the soils did, that different parts of the same vineyard would ripen at different times. It was this understanding of Napa’s terroir that he wanted to bring to Opus. His first week, however, consisted of back-to-back office meetings. “Don’t ever schedule a week for me like that again,” he told his PA.  Silacci arrived at Opus One with his eyes wide open and mouth shut, wanting to observe how the operation was working – and where potential problems lay. While everyone knew what they were doing, h felt that a sense of collective responsibility – and the passion that comes with that sense of ownership – was missing.  In such a big organisation – operating as part of the Mondavi stable in Napa – he wasn’t going to be able to change things overnight, but Silacci didn’t waste any time in the vineyard. When he arrived, the viticultural teams worked across the brands. One week they would be pruning To Kalon (Napa’s prized vineyard, of which 100 acres goes into Opus One), and the next week they would be pruning vines for a $25 bottle of Chardonnay in Carneros. For Silacci, this didn’t make any sense, and the vines needed to be treated differently. He knew from experience that a permanent viticultural team taking ownership of the vines they cared for would improve the quality of the fruit. Within four weeks, he had two teams dedicated solely to the Opus One vineyards. Changing attitudes in the cellar was not so easy. “It was very difficult to integrate with the team,” admits Silacci. “They were very set in their ways and were not really interested in doing things differently.” Silacci identified that it wasn’t what they were doing, but their attitude towards doing it that he felt was wrong. “The cellar crew only did one thing at a time,” says Silacci. “That was their reason for doing something well.” But Silacci, true to form, took a different approach. “Any living thing, human or plant, has to have a sense of urgency,” he says. “If you give people too little work to do and vines too much water, they develop a sense of leisure, they get distracted and miss opportunities… But if you give people too much to do and the plant too little water, they develop a sense of anxiety. They are stressed, which is not healthy and they make mistakes.” Silacci’s goal was to find a middle path. More than that, like his mentors before him, he wanted them to take responsibility in what they did and, with that, instil more passion in the team. “I knew they understood the mechanisms of winemaking,” says Silacci, “but I didn’t know if they felt it. I don’t know if they are passionate about what they do.” He decided to split the cellar team into two teams of three. Each was given 22 rows of the top vineyard. “Between them they had to make all the decisions on pruning, suckering, fruit drop, harvest decisions – everything.” Each team would then make around 1,000 bottles each at the end of the year.  Projects like this, Silacci believes, not only gave his team a sense of autonomy and responsibility, but it helped build passion for what they were doing. “You create a sense of urgency, and you get back a sense of focus,” he says.  Silacci believes that a consensus among the team is key – but only if everyone is equally invested in the final product. Today he has a permanent team of five, who together create the final blend. They are also joined at the later stages by Mouton’s Jean-Emmanuel Danjoy and another of the Mondavi team. Typically, they produce over 50 blends each year before making their decision. And it’s the most important decision of the year. “Blending really is at the heart of Opus One,” Silacci says.  The idea is that everyone in the team has a voice – and everyone is listened to equally. He feels it took 10-15 years for the team to completely understand this consensus-driven approach.  While the theory may not always work, admits Silacci (“Ultimately it is my head on the chopping block”), his aim is to empower his team with responsibility. Like his mentors before him, he loves to give them autonomy in their role, allowing them to figure it out on their own – meaning they’re more invested in what they do. “We all have a blind spot,” he says, “But if you have people standing with you, looking out, they mask your and other people’s weaknesses and you build a circle of people each with their strengths,” he says. For Silacci, the collective – like a blend – is stronger than the individual. “The very best teams,” he says in a calming, zen-like tone, “are not circles, but spheres.” And that perfect sphere is what he continues to strive for at Opus.

Under the tenure of winemaker Michael Silacci Opus One has gone from strength to strength. But it’s not him or owners Mouton-Rothschild and Mondavi that are at the heart of its success; for Silacci, it’s all down to the power of collective responsibility

After 21 years at cult Napa estate Opus One, Michael Silacci believes much of his success lies in collective responsibility. Here’s why.

Opus One’s Michael Silacci on the power of collective responsibility

We have unearthed an absolute gem in the guise of Rosso della Centa, a 100% Merlot wine grown on just one hectare of a distinct marl clay hillside in Friuli, Italy. The wine is the creation of one of Italy’s top winemakers Nicola Manferrari who first produced the wine in 1985 and has gone on to release it only in top vintages, producing just 1200 bottles per vintage. 

As we have managed to source a small parcel of Rosso della Centa 2010, we explore the history of this incredible and rare wine.  Friuli ranks highly among Italy’s finest regions for white wine production, producing some of the most vibrant, mineral, saline whites on the planet. The global reputation of the top wines of Friuli continues to grow, gaining fans throughout the world and firmly positioning it on the global fine wine map.   Whilst more famous for their white wines, top grower Nicola Manferrari has a very special one-hectare plot dedicated to red wine. On taking over the family vineyards in 1982, Nicola was not happy with the quality of wine coming from this Merlot site. So much so he took to studying French and French winemaking to learn the secrets of Bordeaux and then apply these techniques to his own wine, to get the best out of this unique site. He states that François Champagnol’s Elements de physiologie de la vigne was one of the most intellectually stimulating reads of his life. Nicola Manferrari is one of Friuli’s original trailblazers. Along with Mario Schiopetto, Josko Gravner and Silvio Jermann, Manferrari was just one of a handful of producers in the 1980s who had the vision and courage to follow his convictions.

He experimented with the 1982,’83 and '84 vintages before he was happy with the techniques he had adopted and, matched with the perfect weather, managed to produce something exceptional, releasing the inaugural Rosso della Centa in the 1985 vintage. Nicola was confident that he could create the first world-class red wine from the region and was not swayed by his neighbouring premium sites opting to plant Cabernet Sauvignon rather than Merlot. But for Nicola he believed the Merlot was perfect for the clay and collio marl soils in which Cabernet Sauvignon struggled.   The ’85 was a critical success, described by the critics as the "First Great Friuli Red". Other greats of the region include Enzo Pontoni of Miani fame and Christian Patat from Ronco del Gnemiz have followed in his footsteps making incredible Merlots from the Friuli region.
Nicola Manferrari continued to improve the wine buoyed by its critical acclaim, further reducing the yield, increasing the vine density (more than 7000 hectares per hectare), introducing shorter pruning techniques, using no fertiliser and complete grassing in the vineyards to improve the soil health. The wine is fermented in small 12 hl wooden vats and are matured in small oak barriques for four years. Only the finest vintages are released as Rosso della Centa. 
In the summer of last year Monica Larner (Wine Advocate) had the opportunity to taste some more recent vintages of Rosso della Centa. “Looking over my scores, I can't help but notice how consistent they are across vintages and varieties. Results like these are hard to achieve, but not at Borgo del Tiglio. She goes on to describe the ’06 as “musical and operatic in character… there is complete harmony and silkiness here in another gem from Borgo del Tiglio’s cellar”.

"Nicola Manferrari and his family have been working tirelessly since the 1982 vintage to become a benchmark for winemaking in Friuli Venezia Giulia." Monica Larner, Wine Advocate 

Larner did not have the opportunity to taste the mythical 2010 but we pulled a cork on it this week to find out how the wine has developed and we were blown away by the quality. This is a superb rendition retaining everything that is great about Italian wine – the acidity, freshness, dried floral notes and herbal spice along with all the greatest assets of fine Merlot – the rich expansive multi-layered tannins that provide tremendous depth on the palate and the rich mid-palate juiciness full of black fruits and now with age a beguiling leather and earthy savoury notes. The wine has tremendous energy whilst showing handsome tertiary development and to retain so much acidity in a grape that often lacks it underscores just how fantastic this wine is. 

Nicola believes this steep southwest slope of marl and sandstone is perfectly adapted for his old vine Merlot providing a marked elegance and complexity in his Rosso della Centa. The 2010 certainly reflects this and with only 1200 bottles produced virtually impossible to find. This is a unique parcel unlikely to be seen again and is entering into a beautiful drinking window. This wine is a piece of Italian winemaking history and one for any afficionado not to miss. 

It is always difficult to put fine wine into words but Nicola Manferrari’s philosophy outlined on his website gives possibly the greatest insight into this pioneering spirit of Friuli:
“I believe that in effect, the path I have followed has left its mark on the character of my wines which have, according to many, their own maker’s trademark. Over the last twenty years, I have transformed, studied and debunked certain common beliefs and have also overcome - while allowing plenty of room for the sacrilegious power of empirical observation – some of my own personal taboos. I have observed, researched and innovated in the face of hypocrisy and prejudice. 

"Often, however, while doing this I have unwittingly renewed ties with ways of the past which were interrupted by a modernity which had lost all sense and memory. It was probably my unorthodox approach to the world of wine that has guided my choices, meaning this also includes my checkered educational history; I was at the same time a child of scientific teachings and an orphan of technology. This has taught me to take absolutely nothing for granted, and the words of Galileo, which accompany me wherever I go, have taught me to be humble when facing all situations, and to be dignified when dealing with people.”
