How Cognac Is Made: A Step-by-Step Guide to the Art of Cognac Production
The Art of Cognac: How This Legendary Spirit Is Made
Cognac is more than just a drink—it’s a masterpiece crafted through centuries of tradition, expertise, and strict regulations. But how exactly is Cognac made?
In this guide, we’ll take you through the entire process, from grape selection to distillation, aging, and bottling.
1. The Grapes: The Foundation of Cognac
Unlike whiskey, which is made from grains, Cognac starts with white wine grapes, primarily Ugni Blanc. These grapes are essential because they produce a high-acid, low-alcohol wine, perfect for distillation.
The Key Grapes Used in Cognac
- Ugni Blanc (98% of production) – Offers high acidity and floral notes.
- Colombard & Folle Blanche – Occasionally used for additional complexity.
The grapes are harvested once a year in September-October and pressed into juice to begin fermentation.
2. Fermentation: Turning Grapes into Wine
The freshly pressed grape juice undergoes natural fermentation for about 5-7 days. No sugar is added—only the natural sugars from the grapes ferment into alcohol.
The result? A low-alcohol white wine (8-10% ABV), which is tart, acidic, and unsuitable for drinking but perfect for distillation.
3. Distillation: Transforming Wine into Eau-de-Vie
Cognac must be distilled twice using traditional copper pot stills (Charentais stills). This method concentrates the flavors and removes impurities, creating a pure and aromatic spirit.
The Two-Step Distillation Process
- First distillation – The wine is heated in copper stills, producing a liquid called "brouillis" (about 30% ABV).
- Second distillation – The brouillis is distilled again, and only the "heart" (middle portion) is kept, reaching 70% ABV.
The final product is called eau-de-vie ("water of life")—a clear, strong, and fragrant spirit ready for aging.
💡 Fun Fact: The distillation process must be completed before March 31st, according to Cognac regulations.
4. Aging: The Magic of Oak Barrels
Cognac gains its rich color, aromas, and depth from aging in French oak barrels made from Limousin or Tronçais oak.
Cognac Aging Rules
✅ Minimum aging: 2 years (but premium Cognacs age for decades).
✅ Barrel effect: The oak imparts flavors of vanilla, spice, caramel, and dried fruit.
✅ Angel’s Share: About 2% of Cognac evaporates each year, adding depth to the remaining spirit.
Cognac Aging Classifications
- VS (Very Special) – Aged at least 2 years.
- VSOP (Very Superior Old Pale) – Aged at least 4 years.
- XO (Extra Old) – Aged at least 10 years.
- Napoléon, Hors d’Âge & Rare Cognacs – Aged well beyond 10 years for complex flavors.
The longer a Cognac ages, the more smooth, refined, and luxurious it becomes.
5. Blending: Crafting the Perfect Flavor
Unlike whiskey or wine, Cognac is rarely sold as a single vintage. Instead, Master Blenders (Maîtres de Chai) skillfully combine different eaux-de-vie to create a harmonious and balanced Cognac.
🔹 Some Cognacs blend 100+ different eaux-de-vie, sourced from different years and vineyards.
🔹 The goal is to maintain consistency, ensuring each bottle delivers a signature taste.
💡 Example: Hennessy XO blends over 100 eaux-de-vie aged up to 30 years for complexity.
6. Bottling: The Final Touch
Once the Master Blender achieves the perfect blend, the Cognac is filtered and bottled. Some may be slightly diluted to adjust the ABV to 40%, the legal standard for Cognac.
From here, the Cognac is ready to be savored, collected, or gifted—a true testament to time and craftsmanship.
