Beaujolais — Gamay, Granite, and the Art of Carbonic Maceration

Beaujolais occupies a curious place in the wine world: simultaneously dismissed (Beaujolais Nouveau) and acclaimed (the ten Crus). The best wines from granite-soiled villages like Moulin-à-Vent and Morgon are serious, age-worthy, and strikingly underpriced compared to their quality.

Geography

Beaujolais runs south from Mâcon along the Saône Valley. The northern half — the Haut-Beaujolais — is granite and schist, producing the finest wines. The flatter southern half (Bas-Beaujolais) is limestone and clay, source of basic Beaujolais and Beaujolais Villages.

The ten Crus are all in the granite north:

1. Brouilly — largest, most accessible; cherry, violet
2. Côte de Brouilly — granite hill centre of Brouilly; more structured
3. Morgon — "Burgundian" body; dark cherry, wild herbs; ages well
4. Fleurie — silky, floral, fragrant; most approachable premium Cru
5. Moulin-à-Vent — the "King of Beaujolais"; structured, powerful, ages 10+ years
6. Chiroubles — highest altitude; most delicate, floral
7. Chénas — smallest Cru; mineral, dried rose petal
8. Juliénas — spicy, structured; good ageing potential
9. Régnié — accessible, raspberry-forward
10. Saint-Amour — light, fruity; lovely for early drinking

Climate

Continental with Burgundian influence. Warmer than Burgundy but cooler than the Rhône. Spring frost is a risk; autumn harvest is typically dry and warm. The granite soils drain well and warm quickly.

Key Grape

Gamay Noir à Jus Blanc — the only red grape of importance. Small berries, thin skins, naturally high acid. On granite, it produces wines of remarkable perfume and freshness.

Carbonic Maceration — The Beaujolais Technique

Traditional Beaujolais is made by carbonic maceration (macération carbonique):

1. Whole, uncrushed grape clusters are loaded into a closed vessel.
2. The vessel is flushed with CO₂ to displace oxygen.
3. Fermentation begins inside the grape berry — intracellular fermentation.
4. Sugars are partially converted to alcohol inside the berry; glycerol and esters are produced, giving the wine its characteristic soft, candied red fruit.
5. After 5–15 days, grapes are pressed; the resulting wine finishes conventional fermentation.

Semi-carbonic maceration (the common variation): some grapes at the bottom of the vessel are crushed by weight, starting conventional fermentation. CO₂ produced creates an anaerobic environment for upper, intact clusters. Most Beaujolais Crus use this variation.

Result: Low tannin, high fruit expression, bright acidity, and a distinctive cherry/banana/bubblegum aroma (isoamyl acetate from intracellular fermentation).

Beaujolais Nouveau

Released the third Thursday of November each year, Beaujolais Nouveau is fermented, finished, and shipped within weeks of harvest. It is a marketing phenomenon (Georges Duboeuf's genius) and a legitimate seasonal pleasure, not a great wine.

Famous Producers

• Marcel Lapierre — the godfather of natural Beaujolais; Morgon with no SO₂
• Jean Foillard — benchmark Morgon; serious depth and age-worthiness
• Georges Duboeuf — the largest négociant; reliable across all levels
• Jean-Paul Thévenet — Morgon; low intervention, great elegance
• Château Thivin — Côte de Brouilly; excellent, consistent quality
• Louis-Claude Desvignes — Morgon; traditional style with age-worthy structure

Wine Styles

Beaujolais Nouveau: Light, fruity, simple; banana and cherry candy; drink within 6 months.

Beaujolais / Beaujolais Villages: Fresh, light reds; cherry, strawberry; drink 1–3 years.

Cru Beaujolais: The serious tier. Varies by Cru:

• Moulin-à-Vent ages like light Burgundy (5–10+ years)
• Morgon develops earthy, complex secondary character over 5–8 years
• Fleurie is best 2–5 years — lose the flower freshness and it loses its identity

Making Carbonic Maceration Wine

This technique can be applied to any thin-skinned red grape (Gamay, Grenache, Carignan, Cinsault):

1. Harvest intact clusters — no crusher-destemmer.
2. Fill vessel; flush with CO₂ if available (or allow natural CO₂ to build from surface fermentation).
3. Seal vessel. Hold at 28–32°C for 7–14 days (taste daily from day 7).
4. Press when aromatics are right and the berry juice is at 4–6°Bx.
5. Ferment pressed juice conventionally to dryness.
6. No oak (or very light). Bottle early (by February/March) to preserve freshness.
