DiamAndes Winery, Uco Valley: Blend Tastings & How to Visit

DiamAndes is one of those wineries we choose because we genuinely love what they are trying to do. For us, it’s the perfect winery to work with.

It’s not just about the architecture—although it is impressive. DiamAndes was named the best winery architecture in the world back in 2011, but it is about how they combine that design with technology and a very clear vision.

A visionary winery in the Uco Valley

I met them long before they were making wine. Back then, they were pistachio growers.

Bodega DiamAndes belongs to the Bonnie family, originally from Belgium, and it is part of the Clos de los Siete project. Within Clos de los Siete, it’s one of the five wineries, and it has its own very strong identity while still being part of that larger vision of quality in the Uco Valley.

After harvest, they cool the grapes in cold chambers for 12 to 24 hours. It’s a small detail, but it makes a big difference, especially for white grapes, helping to preserve freshness and enhance aromas and flavors.

Technology is everywhere in the winery. Everything is fully controlled digitally, to the point where the winemaker could be in France and still manage the tanks from his phone. That level of control is something you really feel in the final wines.

Why visit DiamAndes Winery?

At Peter Wine Tours, what we like most about DiamAndes is its focus.

DiamAndes is not about volume. They produce less than a million bottles a year and invested around 26 million dollars just to build the winery. All of that effort goes into one thing: making the best wines possible.

And then there’s the place. Right at the foot of the Andes, in one of the most beautiful parts of the Uco Valley, everything comes together—architecture, location, technology, and philosophy.

If you ask me where I would want to work if I were making wine, the answer is easy: DiamAndes.

• Getting there: roughly 1 hour 15 minutes to 1 hour 30 minutes by car from Mendoza city (Ruta 40 and then secondary roads). Because tastings involve wine, most guests come with a private driver or on a guided tour.
• Visits: a French-influenced project at around 1,100 metres. Visits and tastings are by appointment.
• Best time of year: harvest runs from late February through April and is the most vivid moment in the vineyard; September to December gives you green vines, snow still on the Andes and easier availability.
• Peter’s note: excellent for explaining how a French-style blend is conceived and what each variety contributes.
• Pairs well with: another Los Chacayes winery, since they are only minutes apart.
