The Winds of Wine: The Zonda

TArgentina Vineyard Malbechey call it Huayrapuca, “the witches’ wind.”  It sends birds flying, makes the sun appear brown, and knocks down trees. When they feel it approaching, people complain of sleeplessness, anxiety, a suffocating feeling, and depression. It usually starts up between noon and six pm, can last anywhere from one to 12 hours, and sounds eerily like a human whistling sound.

They also call it the Zonda wind, “viento Zonda.”  Technically, the Zonda wind is a type of foehn wind, that is, a dry, down-slope wind that occurs on the lee (downwind) side of a mountain range. The Zonda is a regional term used for this type of wind as it occurs over those parts of western Argentina tucked into the slopes of the Andes, including the wine regions of Mendoza, La Rioja, and San Juan.  The wind is especially brutal in these areas due to the high altitude of the mountain range it must climb over (and swoosh down.)

The Zonda forms as a result of humid air rising off the Pacific Ocean, where it travels up and over the Chilean side of the Andes.  In the winter it helps the snow build-up in the high elevations of the Andes, which provides the much-needed melt-off (and the possibility of irrigation) to this otherwise arid area. The wind—as long as it stays somewhat moderate—can also help keep the vineyards dry, hygienic, and with a low level of risk from molds and fungi.

Argentina Andes ValleyIn the spring and summer, however, the Zonda can create havoc as it descends down the Argentine side of the mountains.  It loses its moisture, becomes warmer and warmer, and gathers up large clouds of dust.  The Zonda generally rushes off the mountains at 25 miles per hour (40km/h) but can reach speeds of 120 miles per hour (~200 km/h). The Zonda can raise temperatures by as much as 54°F (30°C) in just a couple of hours; and the wind event is often followed by a freezing cold front.  No wonder people go crazy!

While this unique weather phenomenon is a necessary part of the terroir of the region, it can also be disastrous to the vineyards.  A Zonda in the spring can wind-burn a vine’s leaves and shoots or shake them right off the vine. The cold front that often follows the hot, dry wind can bring with it the risk of severe frost damage.  For an interesting, short interview with a winemaker in his vineyard after a Zonda, click here.

The Legend of the Zonda

Legend holds that a Calchaqui Indian named Huampi was an arrogant hunter who spared no creature on his frequent hunting trips.  He killed every creature in his path, from the tiniest wood birds to the majestic llama.  His hunting prowess earned him great respect and he enjoyed being revered and even feared.  However, his hunting was out of control to point that all of the region’s animals were on the brink of extinction.

dust stormOne day, as he was returning from the hunt, Pachamama, the earth goddess, appeared before him in a blinding light and said, “Humapi, villainous child of the earth! Do you intend to kill all the animals? Who will feed you when there is no meat, and who will clothe you when there is no wool?”  And then, in a flash, she was gone.

As Huampi slumped against a tree and tried to calm himself, he heard a strange whistling sound.  He felt his face lashed and burnt by the wind.  All around him, trees crashed to the ground, flowers and fruit swirled over his head, and he was blinded by the stinging dust in his eyes.  Pachamama’s revenge was upon him, and since that day, as the Zonda screeches through the Andean valleys, it cries out with a human voice, causing all in its path to stop and pay respect to the power of mother earth.

Le Pays Diois

.

.

According to an old legend, thousands of years ago a Gallic shepherd was placed a bottle of local wine in the cold, winter waters of the Drôme River in order to cool the wine. The shepherd became distracted and forgot about the bottle, only to re-discover it several months later. When he opened the wine, he was met with a delightful spray of spritz; the wine had become lightly carbonated as the waters warmed up in the spring.

Many years later, distant relatives of that first Gallic shepherd can drink the same type of wine, now called Clairette de Die.  The vineyards of Die are located about 30 miles east of the Rhône River, at just about the spot where the Northern and Southern sections of the Rhône Valley meet.  This section of the French département of the Drôme, actually part of the Rhône Valley wine region, is home to four distinct AOCs.

To make authentic Clairette de Die, the grapes are pressed immediately after harvest and placed in vats to ferment at very low temperatures, replicating the process used in ancient times when jugs of wine were kept in the icy waters of the local rivers.  After one or two months of slow fermentation, the sweet, still-fermenting wine is bottled.  The bottles are kept at a constant temperature of about 50°F and the wine is allowed to continue fermenting for another four months.  Fermentation ends naturally when the wine is still slightly sweet.  The wine is usually clarified by being emptied and quickly re-filled (this is the ancient method, after all).  This method of making Clairette de Die, based on the tradition founded 2,000 years ago, was officially recognized as the “ancestral dioise process” in 1941, and considered unique to this area.

There are four AOC’s in the Pays Diois:

Clairette de Die AOC, the most famous of the wines, is a low-alcohol (about 8%), semi-sweet, slightly sparkling wine made using the officially recognized “ancestral dioise process.” Clairette de Die is made from the Muscat Blanc à Petits Grains (75% minimum) and Clairette (25% maximum) grape varieties. Look for aromas and flavors of apricot, peach, tropical fruit, citrus, honeysuckle and white rose.

Crémant de Die AOC, a Traditional Method sparkling wine, historically produced from 100% Clairette, is now made with a Clairette/Aligoté/Muscat blend.  This wine is dry and crisp with aromas and flavors of apple and green fruit.

Coteaux de Die AOC is a still, dry white wine made from 100% Clairette grapes.  The annual production is quite low…only around 1,500 cases, so you’ll most likely have to take a trip to the Diois for a sip!

Châtillon-en-Diois AOC is a still wine made in white, red, and rosé.  The red and rosé versions, produced from Gamay, Pinot Noir, and Syrah, are only made in the vineyards immediately surrounding the village of Châtillon-en-Diois.  The more widely available white version, made from the Aligoté and Chardonnay grapes, is produced throughout the Pays de Diois region.

It’s a tricky word, to be sure. Those in the area pronounce Diois as “dee-wah”. Say it right, and you’re halfway there.
