### 🏛️ Natural Factors (The "Why")

| Factor | Detail | Exam Impact (The "So What?") |
| :--- | :--- | :--- |
| **Gulf Stream** | Warm ocean current | Extends growing season; allows late-ripening Cabs to mature. |
| **Landes Forest** | Large pine forest to the west | Acts as a windbreak; protects vines from Atlantic storms. |
| **High Rainfall** | Frequent Atlantic rain | Causes high humidity/fungal rot. Vintage variation is high. |
| **Gravel (Left Bank)** | Heat-retaining stones | Reflects heat into the canopy; essential for Cabernet ripening. |
| **Clay (Right Bank)** | Cool, water-retaining soil | Ideal for Merlot; keeps roots cool during hot spells. |

### 🍇 The Grapes (The "Risk Management")

*   **Cabernet Sauvignon:** High acid/tannin. Needs heat. Structure & longevity. (Left Bank focus).
*   **Merlot:** Lower tannin. Ripens earlier. Adds body/plum fruit. (Right Bank focus).
*   **Cabernet Franc:** Adds floral notes & spice.
*   **Petit Verdot:** Adds color, tannin, and spice (only in hot years).

### 🛠️ Human Factors (The Winemaking)

1.  **The Blend (Assemblage):** Almost mandatory due to weather risk. If one variety fails to ripen, the other provides the core of the wine.
2.  **Oak Maturation:** Premium wines use **225L French Barriques**. Adds cedar, toast, and tannin structure.
3.  **Malolactic Fermentation (MLF):** Standard for red wines to soften acidity.
4.  **Sauternes (Noble Rot):** Requires humid mornings (Garonne river) and dry afternoons to develop *Botrytis Cinerea*. Hand-picked in multiple passes (*tries*).

### 📊 Quality & Price Hierarchy

*   **Generic:** Bordeaux / Bordeaux Supérieur (High volume, early drinking).
*   **Commune/Village:** (e.g., Pauillac, Margaux). Focus on specific terroir, higher quality, higher price.
*   **Classified:** (Cru Classé 1855). Historical prestige, high investment value, extreme quality.
