Sauternes is a name that evokes images of lush vineyards, golden-hued wines, and the sweet aromas of overripe grapes. Revered by wine lovers around the world, it is one of the most iconic sweet wines in the world. But what exactly is Sauternes, and where is it made? The region of Sauternes is not only famous for producing some of the most exquisite dessert wines but also for its unique geographical features and historical significance in the world of winemaking.
In this article, we will explore the region of Sauternes, its terroir, the winemaking process, and why the wines produced here are so special. You’ll discover the distinct features of the Sauternes region, the importance of the local climate, and the role that the grapes, including Sémillon, Sauvignon Blanc, and Muscadelle, play in creating this luscious, sweet wine. By the end of this guide, you will have a deep appreciation for both the place and the wine that make Sauternes so remarkable.
What is Sauternes?
Before diving into where Sauternes is made, let’s first understand what it is. Sauternes is a French sweet white wine produced in the Sauternes appellation of Bordeaux, located in the southwest of France. Known for its rich and complex flavors of honey, apricots, peaches, and subtle floral notes, Sauternes is made primarily from three grape varieties: Sémillon, Sauvignon Blanc, and Muscadelle.
The key to Sauternes’ sweetness lies in a natural phenomenon called noble rot, or Botrytis cinerea. This fungus affects the grapes, causing them to shrivel and concentrate their sugars, which is essential in producing the intensely sweet, flavorful wines that have made Sauternes famous.
Although often served as a dessert wine, Sauternes can pair beautifully with a wide range of foods, from rich cheeses like Roquefort to foie gras and even savory dishes like roasted chicken. It is a wine that demands attention, often served in small quantities due to its richness and complexity.
The Geography of Sauternes
Sauternes is part of the Bordeaux wine region, one of the most famous wine-producing areas in the world. The Sauternes AOC (Appellation d’Origine Contrôlée) is located within the Graves subregion of Bordeaux, approximately 25 kilometers south of the city of Bordeaux. The vineyards of Sauternes are situated along the Garonne River, with the town of Sauternes itself giving its name to the wine.
Climate and Terroir
The terroir of Sauternes is a combination of several factors that make it uniquely suited to produce sweet wines. The climate in Sauternes is temperate, with mild winters and warm summers. The proximity of the Garonne River plays a vital role in the development of the local microclimate, particularly in the autumn months when the process of noble rot occurs.
During the harvest season in September and October, fog often rolls in from the river, creating a humid, misty environment that encourages the growth of Botrytis. This fog is crucial for the development of the noble rot, as it allows the fungus to slowly attack the grapes, dehydrating them and concentrating their sugars. The resulting berries are small, shriveled, and covered with the characteristic grayish mold. The grapes are picked by hand in multiple passes through the vineyard to ensure that only those affected by the noble rot are harvested at their peak ripeness.
The soil of Sauternes is also a contributing factor to the region’s success. The vineyards are planted on gravelly and sandy soils, which allow for good drainage and heat retention. These soils are ideal for the varieties of grape grown in the region, especially Sémillon, which is susceptible to noble rot. Sémillon, which makes up the majority of the blend in Sauternes, benefits from the conditions in Sauternes, developing a rich, honeyed character that is the hallmark of the wine.
The Sauternes AOC
Sauternes is a designated AOC, meaning that the wine produced in this region is governed by strict regulations that ensure its quality. The boundaries of the Sauternes AOC encompass several villages in the Graves district, including the famous communes of Sauternes, Barsac, Preignac, Bommes, and Fargues.
While Sauternes is primarily associated with the town of Sauternes, the neighboring village of Barsac is also known for producing a distinct type of sweet wine, referred to as Barsac. Although Barsac wines are also made using the same methods as Sauternes and often contain a similar blend of grapes, Barsac wines are produced under a separate AOC. The main difference between the two is that Barsac is legally allowed to declare itself as a dry wine, though it is often made in a very similar style to Sauternes.
The relationship between the two regions is often compared to that of Chablis and Côte de Beaune in Burgundy: two distinct areas producing similar wines with unique nuances. In fact, Barsac wines are sometimes considered a bit lighter and more refreshing than those of Sauternes, but both are highly regarded for their complexity and quality.
Grapes Used in Sauternes
Sauternes wines are typically a blend of three main grape varieties: Sémillon, Sauvignon Blanc, and Muscadelle. Each of these varieties brings a distinct characteristic to the wine, resulting in the harmonious and complex flavor profile that Sauternes is known for.
Sémillon: This grape variety is the backbone of most Sauternes wines, accounting for the majority of the blend. Sémillon is particularly susceptible to noble rot, which allows the grapes to develop the sweet, honeyed flavors that define Sauternes. It contributes richness, body, and the characteristic waxy, lanolin-like texture to the wine.
Sauvignon Blanc: While Sauvignon Blanc is known for its crisp, acidic character, in Sauternes it plays a different role. It adds freshness and balance to the wine, cutting through the sweetness and providing the necessary acidity to keep the wine from becoming cloying. Sauvignon Blanc also contributes aromatic notes of citrus, lime, and grassy elements.
Muscadelle: Muscadelle is a fragrant grape variety that adds floral notes and a touch of complexity to Sauternes. It’s not as commonly used as Sémillon and Sauvignon Blanc but can contribute to the wine’s overall aromatic profile, offering scents of jasmine, honeysuckle, and sometimes orange blossom.
The combination of these three grape varieties results in a balanced wine that has both richness and vibrancy, making Sauternes a versatile and highly prized drink.
Winemaking Process
The winemaking process in Sauternes is a meticulous and labor-intensive procedure, primarily because of the way the grapes are harvested and the role that Botrytis plays in the final product.
Harvesting the Grapes
Unlike most wine regions, where grapes are picked at the same time, the grapes for Sauternes are harvested in several passes, or “tries.” As the noble rot affects the grapes unevenly, the winemaker must wait until each bunch of grapes reaches the optimal level of ripeness and concentration before it is picked. This can mean several passes through the vineyard, sometimes over a period of weeks, ensuring that only the best grapes are harvested.
The timing of the harvest is crucial. If the grapes are picked too early, they won’t have developed the necessary sugar concentration, while picking them too late can result in the loss of acidity, which is important to balance the sweetness of the wine.
Fermentation
Once harvested, the grapes are gently pressed, and the juice is fermented. During fermentation, the natural yeasts in the must (the freshly pressed juice) begin to convert the sugars into alcohol. Because Sauternes is a sweet wine, the fermentation process is stopped before all the sugars are converted, either by adding grape spirits (fortification) or by chilling the wine to halt fermentation. The result is a wine with higher alcohol content (around 13-14%) and a significant amount of residual sugar, which gives Sauternes its signature sweetness.
Aging
After fermentation, Sauternes wines are typically aged in oak barrels for anywhere from 12 months to several years, depending on the style of wine being produced. The oak imparts flavors of vanilla, spice, and toast, which complement the honeyed and fruity character of the wine. The aging process allows the wine to develop greater complexity, deepening the flavors and enhancing the rich texture.
The Best Producers of Sauternes
Sauternes is home to some of the most prestigious wineries in the world, and many of the estates here have a centuries-long tradition of producing exceptional wines. Some of the top producers of Sauternes include:
