Assemblage

Assemblage of champagne: a work of art of versatility

Introduction

Assemblage, also known as cuvée, is a crucial process in the production of wine. Champagne. It is the art of combining different base wines into a harmonious whole to create a wine with a unique character and high quality. This process requires not only technical precision, but also a deep sensory sensitivity and years of experience.

Basics of assemblage

Champagne is traditionally made from three main grape varieties: Chardonnay, Pinot Noir and Pinot Meunier. Each of these grape varieties brings its own unique characteristics to the blend. Chardonnay gives the champagne freshness and elegance, Pinot Noir provides structure and complexity, while Pinot Meunier contributes fruitiness and softness. The proportion of each grape variety can vary, depending on the desired style of the final product.

The process of assemblage

1. Harvest and vinificationThe process begins with the careful harvesting of the grapes. Each grape variety and each vineyard are vinified separately in order to preserve their individual characteristics. The base wine undergoes an initial fermentation, during which sugar is converted into alcohol, and is then stored for further maturation.
2. Tasting and selectionAs soon as the base wines are ready, the work of the cellar masters begins. The wines are tasted and assessed to determine their suitability for blending. This requires a fine sensory perception and a deep understanding of the development of the flavours and structures of the wines.
3. Composition of the cuvée: In this step, the different base wines are blended together. The cellar masters endeavour to achieve a perfect balance between the individual components. The challenge is to create a wine that is consistent year after year, but at the same time reflects the characteristics of each vintage.
4. Second fermentation and maturationAfter the cuvée has been assembled, the wine is bottled and yeast and sugar are added to initiate the second fermentation (Méthode Champenoise) in the bottle. This fermentation produces the characteristic fine bubbles of Champagne. The wine then matures on the lees for several months or even years, which gives it additional complexity and depth.

The influence of assemblage on the Champagne style

Assemblage has a significant influence on the style and quality of the finished Champagne. Here are some of the main styles that can be achieved through different assemblage methods:

1. Non-Vintage (NV)The most common form of champagne. Wines from several vintages are blended together to ensure consistent quality and style. This makes it possible to balance out the natural fluctuations of the harvests and offer a reliable flavour.
2. VintageUnlike non-vintage champagnes, a vintage champagne comes from a single, particularly outstanding vintage. These wines reflect the special climatic conditions and the quality of the grapes from that particular year.
3. Blanc de BlancsA champagne made exclusively from Chardonnay grapes. These wines are often particularly elegant, with pronounced citrus flavours and a fine minerality.
4. Blanc de NoirsThis champagne is produced exclusively from dark-coloured grapes (Pinot Noir and/or Pinot Meunier). It is characterised by more body, fruitiness and often a certain spiciness.
5. RoséRosé champagne can be produced either by adding a small proportion of red wine to the cuvée or by the so-called "saignée" method, in which the skins of the red grapes remain in contact with the must for a short time. These wines typically have red fruit flavours and a certain fullness.

The role of the cellar master

The role of the cellar master, also known as the "chef de cave", is of central importance in the assemblage. These professionals contribute not only their technical skills, but also their sensory skills and creativity. They must be able to judge the quality and potential of the individual base wines and develop a vision for the finished champagne.

The importance of terroirs

Another important aspect of the assemblage is the consideration of the different terroirs of the Champagne region. The different soils, climatic zones and vineyard positions all contribute to the diversity of the base wines. A deep understanding of these terroirs enables the cellar masters to select and combine wines that complement each other perfectly and reflect the unique character of the region.

Conclusion

The blending of Champagne is a true art form that requires technical precision, sensory sensitivity and in-depth knowledge of the wines and terroirs of Champagne. By skilfully combining different base wines, the cellar masters create unique and highly complex wines that are appreciated worldwide for their quality and versatility. This process is at the heart of Champagne production and is the key to the different styles and flavours that make Champagne so special.
