OVERVIEW
Alsace, nestled in northeastern France along the borders of Germany and Switzerland, is a unique wine region celebrated for its aromatic white wines. The region's diverse terroir is shaped by its location between the Vosges Mountains and the Rhine River, providing a range of microclimates and soil types that contribute to its distinct wine styles. Alsace is known for varietal labeling, a rarity in France, with Riesling, Gewürztraminer, Pinot Gris, and Muscat being the key grape varieties. The wines are often dry, highly expressive, and characterized by floral, fruity, and mineral notes. Alsace also has a prestigious classification system, including AOC Alsace, Crémant d’Alsace for sparkling wines, and the esteemed Alsace Grand Cru designation for exceptional vineyard sites. With its rich blend of French and German influences, Alsace offers a singular expression of viticulture.
HISTORY
The history of Alsace as a wine region is deeply intertwined with its geographic location and complex political history. Situated at a cultural crossroads between France and Germany, Alsace has a winemaking tradition that dates back to Roman times, around the 1st century AD, when vineyards were first planted. By the Middle Ages, Alsace had established itself as a prominent wine-producing region, with its wines highly sought after throughout Europe. The monasteries played a crucial role in advancing viticulture, cultivating vineyards and improving winemaking techniques.
From the 16th to the 18th centuries, Alsace experienced a golden age of winemaking, producing some of the most prized wines in Europe. However, this prosperity was disrupted by a series of tumultuous events, including the Thirty Years’ War (1618–1648), which devastated the vineyards, and the region's subsequent annexation and shifting control between France and Germany. These political changes, particularly during the Franco-Prussian War (1870–1871) and the World Wars, shaped Alsace’s viticulture and cultural identity.
Despite these challenges, the 20th century marked a period of revival for Alsace wine. After the end of World War II, Alsace became part of France again, and winemakers focused on restoring quality and reputation. The introduction of the Appellation d’Origine Contrôlée (AOC) system in 1962 helped solidify Alsace's standing as a premier wine region. The region’s focus on varietal wines, precise labeling, and terroir-driven practices set it apart from other French wine regions.
Today, Alsace is renowned for its aromatic whites and sparkling wines, with a unique fusion of French and German traditions that reflects its storied past. Its commitment to sustainability, biodynamics, and preserving historic vineyard practices underscores the resilience and innovation of its winemaking community.
REGIONS
Alsace, located in northeastern France along the border with Germany, is a wine region celebrated for its unique terroir and diverse microclimates. While Alsace does not have subregions in the same way as some other French wine regions, it is often divided geographically and topographically into key areas based on terroir and appellations. Understanding the region's layout helps to appreciate its wine diversity.
Bas-Rhin (Northern Alsace)
The northern part of Alsace is cooler and less steep than the south, leading to wines that are typically lighter and more delicate. The soils here are diverse, with limestone, marl, and sandstone contributing to wines with bright acidity and floral characteristics. Notable Grand Cru vineyards include Zotzenberg, Altenberg de Bergbieten, and Muenchberg, which excel in varieties like Riesling and Sylvaner.
Haut-Rhin (Southern Alsace)
The southern section of Alsace is considered the heart of the region's winemaking and produces the majority of its Grand Cru wines. The Vosges Mountains provide a rain shadow effect, making the climate sunnier and warmer, which contributes to fuller-bodied and more intense wines. Soils in the Haut-Rhin vary widely, with granite, schist, clay, and volcanic origins. These soils are especially conducive to Riesling, Gewürztraminer, and Pinot Gris. Esteemed Grand Cru sites in this area include Rangen, Clos Sainte Hune, and Brand.
CLASSIFICATIONS
AOC Alsace (Appellation Alsace Contrôlée)
Established in 1962, this designation covers the entire region and accounts for about 70% of production. It includes varietal wines, where labels prominently display the grape variety (e.g., Riesling, Gewürztraminer, Pinot Gris, Muscat, Sylvaner, Pinot Noir). AOC Alsace wines vary greatly in style but are often fresh, aromatic, and terroir-driven.
AOC Crémant d’Alsace
Dedicated to sparkling wines made in the traditional method. Predominantly produced using Pinot Blanc, Pinot Gris, Chardonnay, and Pinot Noir. Crémant d’Alsace is known for its elegance and finesse. This category represents about 25% of Alsace’s wine production.
AOC Alsace Grand Cru
Established in 1975, this classification recognizes 51 exceptional vineyards, each with unique terroir characteristics. Grand Cru wines must adhere to stricter regulations, including lower yields and specific grape varieties (Riesling, Gewürztraminer, Pinot Gris, and Muscat, with Sylvaner allowed in Zotzenberg). These wines are often rich, complex, and age-worthy, reflecting the individuality of the vineyards.
VARIETALS
Alsace is renowned for its focus on varietal wines, an uncommon practice in France where blends often dominate. The region is primarily dedicated to white wines, which account for about 90% of its production, but it also cultivates a small amount of red and rosé. Each grape variety in Alsace reflects the region's diverse terroir and climate, producing highly expressive, aromatic wines. Here are the key grape varietals:
Noble Varieties
Alsace's Grand Cru wines must be made from these noble varieties, except for one exception (Sylvaner in Zotzenberg).
Riesling
Style: Dry, elegant, and highly aromatic.
Flavors: Citrus, green apple, peach, apricot, and pronounced minerality.
Characteristics: Known for its crisp acidity, Riesling from Alsace is often more full-bodied than German Riesling. It ages well, developing complex notes of petrol and honey over time.
Gewürztraminer
Style: Rich, aromatic, and often off-dry or slightly sweet.
Flavors: Lychee, rose petal, tropical fruits, ginger, and spice.
Characteristics: A signature variety of Alsace, Gewürztraminer is full-bodied with lower acidity and a pronounced floral and spicy bouquet. It pairs well with spicy cuisine and strong cheeses.

Other Styles and Varieties
Edelzwicker
A traditional blend of multiple varieties, often Sylvaner, Pinot Blanc, and others. These wines are straightforward and meant for everyday enjoyment.
Klevener de Heiligenstein
A specialty wine made from Savagnin Rose, a cousin of Gewürztraminer, grown exclusively in Heiligenstein and nearby villages. It offers a subtle and aromatic profile.
TERROIR
Soil
Alsace is renowned for its complex and varied soils, resulting from millennia of geological activity. The region's vineyards sit atop an intricate mosaic of soil types, each imparting distinct characteristics to the wines.
Limestone and Marl
Found in both Bas-Rhin and Haut-Rhin, these soils retain moisture and provide excellent drainage, yielding wines with structure and bright acidity.
Particularly favorable for Riesling and Pinot Gris.
Granite
Found in higher elevations near the Vosges Mountains.
Produces wines with pronounced minerality and finesse, often associated with Riesling.
Sandstone
Contributes to aromatic, delicate wines with subtle fruit and floral notes.
Often found in the foothills of the Vosges.
Clay
Common in low-lying areas and combined with marl or limestone.
Produces fuller-bodied, concentrated wines, particularly Gewürztraminer.
Schist, Slate, and Volcanic Soils
Found in specific vineyards, such as the Grand Cru Rangen in the Haut-Rhin.
Imparts intense minerality and smokiness, especially to Riesling and Pinot Gris.
Climate
Alsace benefits from a cool continental climate characterized by:
Sunshine
One of the driest and sunniest wine regions in France, thanks to the rain shadow effect of the Vosges Mountains. The average annual sunshine supports consistent ripening of grapes.
Low Rainfall
The Vosges Mountains block prevailing westerly winds, keeping rainfall low (400–600 mm annually). This dry climate reduces the risk of fungal diseases and allows for extended hang time on the vine.
Temperature
Warm summers and cool nights create an ideal environment for retaining acidity and developing aromatic complexity. The long growing season supports slow ripening, essential for Alsace’s signature aromatic whites.
Microclimates
Variations in elevation, exposure, and proximity to the Rhine River create diverse microclimates, enhancing the potential for terroir-driven wines.
Topography
The topography of Alsace is a defining feature of its viticulture:
The Vosges Mountains
Running parallel to the vineyards, the Vosges shield Alsace from excessive rainfall and cold winds. The foothills provide south-facing slopes that maximize sunlight and warmth, ideal for ripening.
Vineyard Location
Most vineyards lie on the lower slopes of the Vosges, between 200–400 meters in elevation. Higher elevations (e.g., Rangen Grand Cru) are cooler and suited to producing wines with high acidity and minerality.
The Rhine River Plain
Provides flat areas with fertile soils, used for growing grapes that produce lighter, everyday wines.
