Krug is a champagne house based in Reims, in France's Champagne region. The producer is known for a methodical approach to champagne production, combining traditional techniques with rigorous quality standards across its range of sparkling wines.

Champagne as an appellation is defined by its chalky soils, cool continental climate, and strict regulations governing production methods. These conditions favor the three classic varieties used in champagne production: Chardonnay, Pinot Noir, and Pinot Meunier. Krug's current range includes non-vintage and vintage expressions, all produced as Brut-style champagnes, reflecting the region's tradition of precise blending and aging in cellars cut into the chalk.

The producer's lineup encompasses a Grande Cuvée as its flagship non-vintage blend, a Rosé expression, and a 2006 vintage release. All are composed from the three primary champagne varieties, demonstrating consistency in the house's approach to grape selection and blending practices across its portfolio.

In 1668, Dom Pérignon is said to have discovered how to make sparkling wine; today his technique is used the world over, although Champagne continues to make some of the finest. France’s most northerly wine region, Champagne is now home to 15,000 growers and 290 ‘houses’. A blend of grape varieties is usually required: white Chardonnay to add fruit and elegance, and two reds – Pinot Noir and Pinot Meunier – to provide body and backbone.

Champagne is a region in northeastern France, approximately 140 kilometers northeast of Paris, defined by strict geographic boundaries established under French appellation law. The region's cool continental climate and chalky soils create conditions uniquely suited to sparkling wine production. The designation "Champagne" is legally protected and applies only to wines produced within these delimited boundaries using prescribed methods.

The region's chalky subsoil—composed largely of Cretaceous limestone—drains rapidly and reflects heat, helping to ripen grapes despite the cool climate. Three grape varieties dominate: Chardonnay, Pinot Noir, and Pinot Meunier, often blended together though Blanc de Blancs wines use Chardonnay exclusively. Champagne's signature method involves a secondary fermentation in bottle (méthode champenoise), where yeast and sugar create carbonation and develop complex flavors over time. Extended aging on the lees further develops texture and aromas. Producers classify vineyards into Premier and Grand Cru designations based on historical quality assessments, and finished wines are labeled by dosage level—ranging from Extra Brut (bone dry) through Brut, Sec, and Demi Sec (progressively sweeter).

Champagne wines are characterized by high acidity, fine bubbles, and layered complexity. Typical flavor profiles include green apple, citrus, and chalk minerality in younger or lighter expressions, evolving toward brioche, toast, and honey notes with bottle age. The interaction between the wine's acidity, the persistent effervescence, and the autolytic characters from yeast aging creates distinctive textural finesse that distinguishes Champagne from other sparkling wines produced elsewhere.
