You likely know that the three main grapes for Champagne are Chardonnay, as well as Pinot Noir and Pinot Meunier, the only two red grapes in the region. The three varieties account for about 99% of the region’s plantings.
But did you know that there are actually eight permitted varieties that can be grown in Champagne?
The others are Pinot Gris, Pinot Blanc, Petit Meslier and Arbane, all white varieties that make up less than .3% of plantings. And, most recently, in 2021, Champagne producers were allowed to start planting Voltis, a white, fungus-resistant hybrid grape.
With the amount of Blanc de Blancs Champagnes found in wine shops and on restaurant menus, you wouldn’t be wrong to think that Chardonnay is very widely planted. But of the main three, it’s the least planted grape variety in Champagne, comprising just over 25,000 acres. In fact, Chardonnay-based Champagnes make up less than 5% of the category.
Due to its mild flavor profile, Chardonnay can be influenced by winemaking decisions rather easily. Its inclusion can add acidity, structure and freshness.
Pinot Noir is a staple in Champagne blends, and the most widely planted variety in the region, encompassing more than 32,000 acres. That’s more than Pinot Noir’s ancestral home, Burgundy. It’s one of just two allowable red grapes in the region, along with Pinot Meunier. They’re responsible for Blanc de Noirs Champagnes, or white wine made from black-skinned grapes.
Pinot Noir, often described as delicate, brings body to the wine, that mouth-filling, structural texture. It also adds lovely aromatics to the blend.
Though historically a blending grape, Pinot Meunier has become a star in its own right in recent years, with 100% Meunier Champagnes becoming increasingly more popular. Excellent examples include bottlings from José Michel, Moussé Fils and Salmon, which all bet most of their production on Meunier.
Pinot Meunier brings those coveted red berry flavors to the fore, but it also balances the overall blend. About 26,000 acres of Meunier are planted in the region.
Pinot Blanc is a white grape variety, but it’s related to Pinot Noir. A color mutation makes certain genes that produce pigment inactive, which creates this white version of Pinot Noir. Its berry size and leaf shape have often been confused with Chardonnay, a distant cousin to Pinot Blanc.
Pinot Blanc has always been grown in Burgundy and Champagne, but Alsace holds the largest plantings in France, with nearly 8,300 acres. Pinot Blanc brings a strong floral profile to the bouquet of the wine and some racy acidity to the palate.
Also known by its historic name, Fromenteau, this pink-skinned grape is well known in still wine, but it’s also one of the seven permissible varieties in Champagne. It’s also a color mutation of Pinot Noir. When blended, Pinot Gris offers fruit and richness.
One of the most obscure varieties in Champagne, Petit Meslier has searing acidity that prevails in even the warmest of years. Like Pinot Blanc, it’s a relative of Chardonnay. One of its “parents” is Gouais Blanc, also a parent of Chardonnay that crossed with another little-known variety, Savagnin.
The flavors in Petit Meslier are often vegetal and can be reminiscent of Sauvignon Blanc. A major bonus is that it’s resistant to frost, the main enemy of Champagne vineyards.
Arbane might be the rarest Champagne grape of all, with just 2.5 acres planted across France in 2006. It’s a light yellow, very late-ripening grape with overbearing acidity that often requires a lot of attention for the low yields that it produces. The flavors are often herbal or green.
Still only grown by a small handful of Champagne houses, Voltis was created by “France’s INRA and Germany’s Julius Kühn as part of a project launched in 2000 to develop PIWI (fungus-resistant) varieties,” according to The Drinks Business. It’s one of several fungus-resistant hybrids developed to help winemakers cope with a changing climate. As of now, if winemakers utilize the grape, it can only make up to 10% of the overall Champagne blend.
Where are the “Forgotten Four” Now?
In 1986, the L. Aubry Fils Champagne house prepared for its 1991 bicentennial by recreating wines that would have been made back in its early days. The idea was to use varieties like Arbane that had fallen out of favor.
But it takes time for grapes to grow and produce viable fruit. It wasn’t until 1994 that Aubry was able to harvest all seven permissible varieties. From those plantings came Le Nombre d’Or, or “The Golden Number.”
Since Voltais is so new, we are not including it in the “forgotten four.”
Champagne Grapes and Climate Change
Champagne’s ever-warming climate is indicative of a global issue writ large. Champagne houses like Bollinger have begun to plant more of the four lesser-used varieties because of their naturally high acidity. Others, like Drappier are starting to take advantage of the new hybrid grape allowed. That helps balance ripe fruit, the other structural component needed to age Champagne.
Other producers balance sweeter fruit by reducing the dosage, or the sugar mixture added to Champagne after disgorgement. A Brut Champagne has less than 12 grams per liter of dosage, but as temperatures continue to climb, dosage levels are being reduced or even eliminated. These zero-dosage bottlings are now incredibly popular with the global Champagne cognoscenti.
Some producers, like AR Lenoble, block malolactic conversion to retain acidity. Malolactic conversion, affectionately known as “malo,” is a process where the sharp malic acid that exists in grapes is converted to a creamier-feeling lactic acid.
Many Champagnes employ this because of the abundance of acidity in the wine, but rising temperatures are lowering acid levels. These are just a few of the methods that producers experiment with to preserve Champagne’s history and flavor. But they certainly won’t be the only ones.
