Alsace is one of the wine world’s hidden gems, known for its charming villages nestled near the Vosges Mountains and a diverse range of varietally labeled wines on offer. Historically part of Germany, Alsace still reflects its Germanic roots in local surnames, the tall green “flutes d’Alsace” used for bottling, and the dominance of cool climate grapes. Like Germany, Alsace avoids the use of new oak and malolactic fermentation, prioritizing the pure, fruity aromas of each grape variety.

Alsace spans approximately 115 miles in length and 25 miles in width, and is divided into two main departments: Bas-Rhin to the north, characterized by lower elevations, and Haut-Rhin to the south, which boasts the majority of its over 51 Grand Cru vineyard sites. With close to five thousand individual growers managing small vineyard plots, the region maintains a strong emphasis on quality and tradition. 

History

The history of Alsace wine is deeply intertwined with the region’s political landscape. After the dissolution of the Holy Roman Empire in 1648, Alsace was ceded to France, marking the beginning of a significant cultural and administrative shift. This transition influenced the region’s winemaking practices, blending French techniques with lingering German influences. 

In 1871, following the Franco-Prussian War, Alsace came under German control, a period that lasted until the end of World War I. During this period, German grape varieties and traditions became further ingrained in the local wine culture. Although the region was seized by Germany again during World War II, it returned to French sovereignty after the war.

After World War II, Alsace producers united to prevent the region from becoming overly industrialized, as had happened in neighboring areas like Germany’s Mosel Valley. This effort resulted in the establishment of three Appellations d’Origine Protégée (AOPs): Alsace AOP, Alsace Grand Cru AOP, and Crémant d’Alsace AOP. Producers strategically focused on promoting brand names over terroir to enhance the region’s marketability and reputation.

There was also a strong push for quality over quantity, leading to the development of bone-dry wines that highlighted Alsace’s ability to produce crisp, precise expressions of its grape varieties. Riesling became the flagship variety, embodying the region’s commitment to modernization and its new signature style.

Climate & Geography

Alsace benefits from a continental climate, characterized by warm summers and cold winters, moderated by the region’s unique geographical position between the Vosges Mountains to the west and the Rhine River to the east. The Vosges Mountains act as a natural barrier, protecting Alsace from north westerly weather systems and creating a rain shadow effect. As a result, the growing season is relatively dry, with most rainfall occurring outside the critical ripening period, reducing the risk of fungal diseases and ensuring healthier grape clusters.

Alsace features an exceptionally diverse soil composition, shaped by its location along a nearly 700-kilometer-long European Cenozoic rift system known as a “graben.” This geological formation has created a wide variety of soil types across the region.

One of the most notable is Grès de Vosges, or pink sandstone, which is prominent in the landscapes of the Northern Vosges and visible in iconic structures like the Strasbourg Cathedral. This soil type provides excellent drainage, is low in nutrients, and retains heat well, making it particularly suited to cultivating Riesling. Other significant soil types in the region include granite, limestone, clay, volcanic deposits, and alluvial gravel, all of which contribute to the complexity and character of Alsace’s wines.

Key Grape Varieties

The majority of Alsace vineyards are devoted to white grapes. The four “noble” grapes of Alsace are Riesling, Pinot Gris, Muscat, and Gewurztraminer. Other varieties include Sylvaner, Chasselas, and Auxerrois. Pinot Noir is the only permitted red grape variety and is used to make light red and rosé wines.

Among these, Riesling stands out as the most prominent, known for its high acidity, vibrant minerality, and aromatic notes of apple, citrus, and exotic flowers. Gewurztraminer is also notable for its intense aromatic profile featuring lychee, rose petals, and spice. This grape produces full-bodied wines with a rich texture and a lingering finish, offering a bold contrast to the more restrained Rieslings. Pinot Gris, appreciated for its versatility, produces wines that range from dry to sweet, with flavors of ripe pear, honey, and spice, while Pinot Blanc is primarily used as a base for sparkling wines.

Notable Subregions

The majority of Alsace’s 51 Grand Cru vineyards are found in the southern Haut-Rhin. Grand Cru sites are strategically located on the eastern-facing slopes of the Vosges Mountains, ensuring optimal sun exposure and drainage. Bas-Rhin, the northern department, features lower elevations and a slightly cooler climate. 

Wine Law and Classification

Within Alsace there are three primary appellations: Alsace and Alsace Grand Cru for still white wines (both sweet and dry), and Crémant d’Alsace for sparkling. Single varietal Alsatian wines are permitted to state the variety on the label. If more than one grape is used, the bottle must be labeled “edelzwicker”, “gentil”, or given a fantasy name.  

The Alsace Grand Cru AOC is reserved for wines made from Riesling, Gewurztraminer, Pinot Gris and Muscat, with one exception: Sylvaner harvested from the Zotzenberg vineyard may also qualify. 

Crémant d’Alsace AOC covers the region’s sparkling wines, which are produced using the traditional méthode champenoise. These sparkling wines are crafted primarily from Pinot Blanc, Pinot Gris, Pinot Noir, Auxerrois, and Riesling.

Alsace is also known for its sweet wines: Vendanges Tardives and Sélections de Grains Nobles. Vendange Tardive translates directly as “late harvest” and is made from any of the four noble grape varieties. Certain minimum ripeness levels must be attained and the grapes may be picked only when official authorisation is given. The best of these wines can be aged for many years.

Sélection de Grains Nobles signifies a wine made from even riper grapes, often at least partly concentrated by botrytis. The preferred grape is Gewurztraminer, as it can produce a high amount of the necessary sugars, especially in warm years.

In 2020, a law was introduced in Alsace requiring wine labels to indicate the sweetness level. Now, labels must include one of the following terms: “sec” (dry), “demi-sec” (off-dry), “moelleux” (medium-sweet), or “doux” (sweet).
