Caduceus Cellars
Verde Valley, Arizona, USA
Maynard James Keenan is inevitably best known as the frontman of Tool, A Perfect Circle and Puscifer, but wine has occupied an increasingly large part of his life for more than twenty years. Caduceus Cellars is not a celebrity side project, but the result of two decades spent trying to understand whether serious wine could be grown in the unlikely landscape of Arizona, and, in the process, helping establish an identity for a wine region that was barely on the map when he began.
Maynard moved to the old mining town of Jerome in northern Arizona in the 1990s. It was the landscape around his home that first made him curious about growing grapes: ancient limestone beds, volcanic and rocky soils, high elevations and a history of viticulture stretching back to before Prohibition. He began planting in the early 2000s, initially working with winemaker Eric Glomski while learning both vineyard and cellar work himself. Caduceus was established in 2004, with Primer Paso – a Rhône-inspired blend that remains part of the range today – among the first wines he made.
It is difficult to understand Arizona wine without first forgetting most assumptions about Arizona. Caduceus and its sister project Merkin Vineyards now work around 40 hectares of vines, spread between six sites in the Verde Valley in the north and the Buhl Memorial Vineyard in Willcox in southern Arizona. The vineyards sit between roughly 1,000 and 1,500 metres above sea level, with the tiny Judith Block above Jerome reaching 1,500m. Further south, Buhl sits at around 1,300m and contains vines planted in 1982, among the oldest surviving post-Prohibition plantings in the state.
These elevations completely change the equation. Winters are genuinely cold and late spring frost is one of the biggest threats to the crop (temperatures can still fall to around -12 to -9°C in early May). Then comes intense Arizona sun, followed in mid-summer by another peculiarity of the region: monsoon season, when a large proportion of the year's rainfall can arrive just as the grapes are approaching harvest. Farming here means negotiating extremes rather than simply heat. Healthy, deliberately low-yielding vines are fundamental; frost fans are sometimes used in spring, while careful leaf removal, open canopies and fans help move air through the vineyards and dry the fruit during the humid monsoon period.
Finding the right grapes for this environment has been an equally long process of trial and error. Early plantings included varieties that proved unsuitable and were eventually removed, while Tempranillo, Garnacha and Malvasia offered some of the earliest clues to what Arizona could do well. From there Maynard expanded into a distinctly Mediterranean palette: Sangiovese, Barbera, Nebbiolo and Aglianico alongside Syrah, Cabernet Franc, Cabernet Sauvignon and others. Rather than trying to reproduce California in the desert, the project has gradually developed its own vocabulary around varieties capable of retaining freshness, dealing with the climatic extremes and, importantly, working well together in blends.
Today there are two principal sides to the project. Merkin Vineyards is centred largely around the organically farmed Buhl Memorial Vineyard in Willcox and produces the more immediate wines, generally aged for eight to ten months in concrete or barrel and intended to be drunk young. Caduceus draws predominantly from the higher-elevation vineyards of northern Arizona and is where Maynard explores more structured, longer-aged wines and smaller experiments. Since 2014 the wines have been made entirely from Arizona fruit, and today virtually everything comes from vineyards under their own control.
The experimentation is important. Maynard's approach has never been to arrive with a predetermined idea of what Arizona wine should taste like, but to learn through repetition - changing varieties, picking dates, fermentation methods, vessels and blends as the vineyards reveal themselves. Earlier picking has become important for retaining acidity, sometimes even bringing fruit in ahead of the monsoon. In the cellar, fermentations are now predominantly with natural yeasts, whilst for aging vessels such as concrete, large and small-format oak and concrete eggs tend to be favoured.
That curiosity is perhaps clearest in wines such as Airavata, Grenache from the limestone and cobble soils of the Eliphante Block, fermented in concrete egg on Viognier lees and inspired by the late Taras Ochota of Ochota Barrels; Anubis, now a blend of Cabernet Sauvignon, Cabernet Franc and Aglianico; and Primer Paso, the Syrah, Malvasia and Petite Sirah blend Maynard first put together in 2004 and has continued to make ever since.
Perhaps most importantly, Caduceus sits within something much larger than a single winery. Maynard has spent much of the last twenty years championing Arizona-grown wine, was involved in the long process that culminated in the recognition of the Verde Valley AVA in 2021, and has invested in the infrastructure around it (vineyards, restaurants, tasting rooms and projects supporting other local winemakers).
There is obviously an unusual story attached to Caduceus, and Maynard's career in music will always make it one of the more recognisable names in our portfolio. But that is ultimately not why we are interested in the wines. What excites us is something much simpler: a grower who has spent more than twenty years trying to understand a difficult and largely unexplored place, making mistakes, changing direction and gradually working out what belongs there. Arizona remains a young wine region, and Caduceus feels less like a finished statement than one of the projects actively defining what the region might become.
