Wine Regions: Bordeaux & Rhône (Lecture Notes)

Bordeaux Overview

  • Bordeaux is described as the largest AOC in France, synonymous with history, prestige, and age-worthy, collectible wines.
  • The name Bordeaux serves a triple purpose: it refers to the region, the river/floodplain system, and the city on the left bank; the term can mean different things depending on context.
  • Geography and layout:
    • Located in Western France.
    • Shaped by the Gironde Estuary, which flows out to the Atlantic.
    • The land is divided by two major rivers: the Garonne and the Dordogne (the lecturer notes them; others say they form a fork creating a left bank, a right bank, and the central area).
  • Climate:
    • Maritime-influenced climate with significant moisture from ocean, estuary, and rivers.
    • This climate moderates extremes but still presents frost risks.
  • Grape dominance and patterns:
    • Merlot is the dominant varietal in Bordeaux overall.
    • Cabernet Sauvignon is the flagship grape of the Left Bank, thriving in gravel soils with good drainage.
    • Merlot is also heavily present on the Right Bank and in the Entre-Deux-Mers (the central area).
  • Historical significance and marketing:
    • Much of Bordeaux’s prestige rests on classifications and estate marketing.
    • The 1855 classification is a cornerstone, created as a marketing tool for the Exposition Universelle (World’s Fair) to promote the best estates.
    • 1855 classification facts (as presented):
    • There were 61 estates ranked across five tiers (crews), historically used to designate quality and price levels.
    • The First Growths (Premier Cru) included three estates from Pauillac (Château Lafite Rothschild, Château Latour, Château Mouton Rothschild), one from Margaux (Château Margaux), and one from Graves (Château Haut-Brion).
    • Initially, four estates were First Growth; one estate was promoted from Second Growth to First Growth (Mouton Rothschild).
    • The system is static and has not changed since its inception, which has been a point of criticism because it can disincentivize estates from improving if they are not recognized by the classification.
    • The left bank’s geography (port access) helped Bordeaux become globally traded and famous; the estuary and river networks enabled shipping wine worldwide, contributing to Bordeaux’s long history (roughly two millennia).
  • Left Bank overview (brief hint before deeper dive): soil and grape focus drive the style of wines from the Left Bank.
  • Important caveat from lecturer:
    • Some pronunciations and names were discussed in a live-talking manner; expect some spellings to vary in class materials (e.g., specific estate spellings and local toponyms).

Left Bank: Geography, Soils, and Grape Composition

  • Soil: Dominantly gravel on the Left Bank; gravel provides excellent drainage, supporting Cabernet Sauvignon.
  • Dominant grape on the Left Bank: Cabernet Sauvignon (the “prized” grape for top estates).
  • Soil impact details:
    • Gravel soils promote drainage; Cabernet Sauvignon thrives with good drainage (i.e., ‘drainage is key’—the speaker notes it dislikes “wet feet”).
  • Merlot and the Left Bank:
    • Merlot is present and used, but the highest-quality estates (top “First Growth” level) are Cabernet Sauvignon driven.
    • Merlot is more prominent in the Right Bank and in the central areas (Entre-Deux-Mers) rather than as the driver of the top left-bank estates.
  • Bordeaux blends (typical composition for Left Bank wines):
    • Primary driver: Cabernet Sauvignon.
    • Common components: Merlot, Cabernet Franc, with smaller amounts of Malbec and Petite Verdot.
  • Vinification tendencies on the Left Bank:
    • New French Oak is highly prized and heavily used in prestige Left Bank wines.
    • In higher-ranked estates (top tiers, i.e., higher crews), the percentage of new oak is very high, contributing to flavor, texture, and price.
  • Overall Bordeaux blend context:
    • Bordeaux red blends are typically Cabernet Sauvignon–driven on the Left Bank; Merlot-heavy blends are more common on the Right Bank.
    • In some subregions (e.g., Graves on the Left Bank side, and the Graves area when discussing the broader Left Bank), Merlot can appear in higher percentages in blends.
  • Quantitative glimpses (as given by lecturer):
    • Red varietal composition in Bordeaux overall (as a rough guide):
    • Cabernet Sauvignon: 24 ext{%}
    • Merlot: 64 ext{%}
  • Sweet wines context on the Left Bank:
    • The Sauternes and Barsac region sits south of the Left Bank; moisture from the Ciron river and other moisture sources helps promote noble rot (Botrytis cinerea).
    • Noble rot yields iconic sweet wines, notably from Sauternes.
    • Grape composition for Sauternes-style/Botrytis wines generally features Semillon as the primary grape, with Sauvignon Blanc and Muscadelle as intermediaries.
    • Botrytis cinerea is the fungus responsible for the dehydration of grapes, producing concentrated grape juice; the wines are extremely sweet when botrytized.
    • In some years, botrytis doesn’t occur; wines from those years may be dry white Bordeaux (e.g., Bordeaux Blanc or Bordeaux Superior) instead of sweet Sauternes.
  • Sauternes classification and notable naming nuances (as discussed):
    • 1855 classification for sweet wines also exists; Sauternes wines are classified, with Barsac allowed to use its own name for certain wines (Barsac as a village within the Sauternes district, offering an alternative naming path).
    • The most famous wine in this category is Château d'Yquem (the top-ranked, often referred to as “Superior Premier Cru” in the old system).
    • A playful discussion occurred about the top wine name and pricing, including a memorable anecdote about eye-dropper tastings for Château d’Yquem due to its extreme scarcity and price point (roughly a multi-hundred-dollar bottle in top vintages).

Right Bank: Geography, Soils, and Key Appellations

  • Soil and climate differences:
    • Right Bank soils feature more clay and limestone, with cooler sites that hold water, which Cabernet Sauvignon does not thrive in due to “wet feet.”
  • Grape dynamics on the Right Bank:
    • Merlot dominates the Right Bank blends; Cabernet Franc plays a supporting role.
    • Cabernet Sauvignon is less dominant on the Right Bank relative to Merlot and Cab Franc.
  • Notable Right Bank appellations:
    • Pomerol: Famous for top wines (e.g., Petrus) but Pomerol has no official classification system like the Left Bank; reputation is driven by the wine’s expression and scarcity.
    • Saint-Émilion: Has its own classification system that is distinct from Bordeaux’s 1855 system; started in 1959 and revised roughly every ten years; the process has had legal challenges and pauses.
  • Saint-Émilion’s Grand Cru classifications (as presented):
    • Two estates cited as Grand Cru Classé A (Premier Grand Cru Classé A in the local nomenclature): Château Figeac and Château Pavie (as named by the lecturer; note that the Saint-Émilion system has seen changes over time in modern practice).
    • The system differentiates between Premier Grand Cru Classé A and Premier Grand Cru Classé B (the complexities and terminology can be nuanced; the lecturer highlighted the blended and can-change nature of the classification).
  • Pomerol notes:
    • Pomerol is unclassified by a formal hierarchy; prestige rests on the wine’s reputation and its estate’s marketing, with Petrus being the most expensive name often cited in discussions.
  • Entre-Deux-Mers (the center):
    • This zone sits between the Garonne and Dordogne rivers; it is known for mass-produced Bordeaux and Bordeaux Superior labels, including Entre-Deux-Mers labels.
    • Varietal emphasis: often Merlot and Sauvignon Blanc are common in this central area.
    • The region is recognized for its value and breadth of production, rather than elite prestige alone.

Rhône Valley Overview (Drilled Areas: Northern Rhône, Southern Rhône)

  • General geography:
    • The Rhône Valley runs north-south; climate and topography shift from north to south.
    • Northern Rhône is cooler and more continental/semi-continental; Southern Rhône is warmer, more Mediterranean with some continental influence.
  • Northern Rhône specifics:
    • Grape focus: Red wines dominated by Syrah; whites (less common) include varieties like Viognier in some zones.
    • Soils: Northern Rhône features gravel and granite soils.
    • Notable grape profiles:
    • Syrah dominates red wines in the north.
    • White varietals in the Northern Rhône include a trio often discussed in Level I: Marsanne, Roussanne, and Viognier (in some subregions).
    • Key appellations in the Northern Rhône include Côte-Rôtie, Condrieu (white-only), Hermitage, Crozes-Hermitage, Saint-Joseph, Cornas, Saint-Péray, and more.
    • Côte-Rôtie (Northern Rhône red) details from the lecture:
    • It references “roasted slopes” as a feature of the terroir: the name Côte-Rôtie evokes the sun-facing, south or southeast slopes.
    • Regulation notes from the lecture:
      • Minimum Syrah content is 80 ext{%}; the only legally allowed grape to blend with Syrah is Viognier (often referred to as “Viognier” or “Begoniere” in the speaker’s phrasing). Co-fermentation is required if Viognier is used.
      • Wines can be 100% Syrah or include up to 20% Viognier (as per Côte-Rôtie rules; presented as the speaker’s point about blending and co-fermentation).
  • Condrieu (Northern Rhône, 100% Viognier):
    • Condrieu is an exclusively white wine appellation producing 100% Viognier.
    • It’s small-production and high-priced due to exclusivity.
  • Monopole mention in Northern Rhône:
    • The speaker mentions a rare, prestigious monopole called Château Grillet near Condrieu (spelled as “Chateau Grier” in the talk), used as an example of a top, tightly controlled site.
  • Hermitage and nearby zones:
    • Hermitage is one of the most prestigious appellations in France with strong sunlight and a south/southeast orientation.
    • Crozes-Hermitage (the speaker’s transliteration of a regional zone) is mentioned as a broader area beneath Hermitage; this area often blends varieties and can include white grapes (Marsanne, Roussanne) alongside Syrah in co-fermented styles, though most Crozes-Hermitage red wines are Syrah-dominated.
    • The speaker notes differences between Hermitage (prestigious, small production, red is often 100% Syrah unless explicitly blended) and Crozes-Hermitage (larger production, more blending opportunities).
  • Southern Rhône highlights:
    • The Southern Rhône is more open, with a flatter and more hilly terrain; the climate is more Mediterranean with some continental influence.
    • The region is famous for Châteauneuf-du-Pape and a wide array of local appellations.
    • Châteauneuf-du-Pape (the “Xigon Das” in the talk) characteristics from the lecturer:
    • It’s the standout Southern Rhône appellation often used as a benchmark for blends.
    • It is typically a blend of multiple grape varieties (often historically many varietals); in modern times, the core blend is usually represented by Grenache as the driver with supporting roles from Syrah and Mourvèdre (GSM).
    • The wines are typically blends (not a single grape) and can feature 13 or more varietals historically; modern practice often refers to roughly 13 or more allowed varietals, with Grenache as the driver in many blends.
    • The wine tends to rely on lower use of new oak relative to Bordeaux, with a preference for neutral oak, cement, or shorter oak influence as a stylistic choice.
    • Gigondas (Xigon Das) is mentioned as a Southern Rhône appellation often used as a value source; it’s usually a GSM blend (Grenache, Syrah, Mourvèdre) and commonly features Grenache as the driver.
    • Be mindful of the distinction between high-end Châteauneuf-du-Pape (which may see extended oak programs) and the more rustic, value-oriented Southern Rhône wines labeled under other appellations (like Côtes du Rhône Villages, etc.).
  • White varietals in the Northern Rhône context:
    • The talk references three white varietals often seen in the Northern Rhône (Beyonier / Maison / Roussanne as potential spellings): Marsanne, Roussanne, and Viognier.
    • In the Northern Rhône these appear in a minority compared to the heavy emphasis on Syrah in red wines.
  • Overall Rhône notes:
    • The North is more continental and slopes toward structured, mineral red wines (primarily Syrah) and lighter whites; the South is more Mediterranean with broader blends, often based on Grenache.
    • The GSM blend concept is central to the Southern Rhône wines (Grenache, Syrah, Mourvèdre) and is a key driver for many appellations beyond Châteauneuf-du-Pape.

Specific Appellations and Concepts to Remember

  • Côte-Rôtie (Northern Rhône, red emphasis):
    • Red wines primarily from Syrah (with permissible up to 20% Viognier per some interpretations; co-fermentation is common if Viognier is used).
    • Minimum Syrah content often cited as at least 80% in many reference sources.
    • Sloped terroir and sun exposure influence the flavor profile (roasted/sun-facing inclines).
  • Condrieu (Northern Rhône, white emphasis):
    • 100% Viognier; small production and high price point.
  • Château Grillet (Monopole, Northern Rhône):
    • A famous monopole (single estate that owns all the land for its appellation) cited by the lecturer as an example; the winery is located near Condrieu.
  • Hermitage and Crozes-Hermitage (Northern Rhône):
    • Hermitage is one of the most prestigious appellations with high reputation and limited production.
    • Crozes-Hermitage provides broader production and may blend with white varieties in some cases; red wines predominantly from Syrah.
  • Châteauneuf-du-Pape (Southern Rhône):
    • Noted for blends; often uses Grenache as the driver, with Syrah and Mourvèdre in support (GSM).
    • The region is characterized by rusticity and value across different producers, with some wines offering excellent price-to-quality in the mid-tier range.
  • Châteauneuf-du-Pape styling notes from the talk:
    • A typical approach includes blending multiple varietals; in many cases, wines can be a blend of two or more grape varieties and can involve Grenache as the main driver with other varieties contributing.
    • Oak usage in Southern Rhône tends to be less aggressive than in Bordeaux, with more emphasis on neutral oak or cement tanks; the wines often emphasize terroir and fruit-forward profiles rather than heavy oak influence.
  • Practical notes on oak and aging (Bordeaux-focused but with cross-region relevance):
    • French oak tends to be harder and requires longer aging to mellow tannins; the aging window often ranges around 1$-$2$ years in wood, depending on region and winery philosophy.
    • Top Bordeaux estates (especially the 61 estates cited in the 1855 system) may use new oak at levels from roughly 40 ext{%}toashighasto as high as100 ext{%} for their premier cuvées; second labels may reuse used oak across subsequent vintages.
    • The oak source areas are primarily from French forests (there are about five major forests for oak); cooperages and brand preferences influence the exact oak origin.
    • The “secondary life” of oak is a practical topic: used barrels are often repurposed for other beverages (sherry, bourbon, whiskey, rum) or sold to other producers; this secondary life can impart flavors to other spirits and fusions.

Key Formulas, Numbers, and Classifications (LaTeX format)

  • 1855 Classification facts:
    • Number of estates classified: 61
    • First Growths (Premier Cru) origins: three from Pauillac (Lafite, Latour, Mouton), one from Margaux (Margaux), one from Graves (Haut-Brion).
    • There were initially four First Growths; Mouton Rothschild was promoted from Second Growth to First Growth.
    • The classification is static and has not changed since its establishment.
  • Grape percentage highlights (for red Bordeaux wines, approximate):
    • Cabernet Sauvignon (overall red Bordeaux): 24\%
    • Merlot (overall red Bordeaux): 64\%
  • Côte-Rôtie (regulatory notes):
    • Syrah minimum: 80\%$$
    • Allowed blend grape with Syrah: Viognier (up to a certain percentage, commonly discussed as up to 20% in practice); co-fermentation required if Viognier is used.
  • Châteauneuf-du-Pape (South Rhône) blends:
    • Common driver: Grenache
    • Typical co-drivers (examples of GSM blends): Grenache, Syrah, Mourvèdre
    • Number of varietals historically allowed/considered: as many as 13+ in classic descriptions; modern practice often emphasizes a core GSM blend with variations by producer.
  • Châteauneuf-du-Pape oak and aging notes:
    • Use of neutral oak or cement; less aggressive new oak compared to Bordeaux; aging trajectory tends to emphasize bottle development over time.

Connections, Implications, and Real-World Relevance

  • Economic and marketing implications of classifications:
    • The 1855 classification’s static nature can constrain estates from adapting to market changes or improving beyond their historical status; it also creates a high price anchor for top estates and drives consumer expectations.
  • Terroir and climate interplay:
    • The Left Bank’s gravelly soils and need for drainage support Cabernet Sauvignon’s structure and aging potential; Right Bank’s clay/limestone soils favor Merlot and Cabernet Franc readability and early approachability.
  • Production scale and accessibility:
    • Entre-Deux-Mers emphasizes mass production and everyday Bordeaux, contrasting with the prestige-driven Left Bank and High-End Right Bank wines.
  • Rhone diversity and terroir expression:
    • The North-South climatic gradient drives the grape profiles: the North leans toward cool-climate Syrah and structured wines; the South emphasizes Grenache-driven blends with a warmer, more Mediterranean influence.
  • Oak as a stylistic tool:
    • The extent of new oak vs neutral oak reveals a wine’s aggressiveness in tannin and oak-driven flavors; Bordeaux’s prestige wines rely heavily on new oak to build texture and aging potential, whereas Southern Rhône and other regions may rely more on other architectural components (terroir, extraction) and use less new oak.

Quick Takeaways for Exam Preparation

  • Bordeaux basics:

    • Left Bank: Cabernet Sauvignon-driven; gravel soils; high oak usage; top estates include Lafite, Latour, Mouton (Pauillac), Margaux (Margaux), Haut-Brion (Graves).
    • Right Bank: Merlot-driven; clay/limestone soils; famous for Pomerol (no formal classification) and Saint-Émilion (its own evolving Grand Cru system).
    • The 1855 classification is a historic, marketing-driven system that is static; Mouton Rothschild was promoted from Second Growth to First Growth.

  • Rhône basics:

    • Northern Rhône: cooler, continental; red wines dominated by Syrah; Condrieu = 100% Viognier; Côte-Rôtie = up to 20% Viognier with Syrah (minimum Syrah 80%); Château Grillet (monopole) as a notable white producer.
    • Southern Rhône: warmer and more Mediterranean; prominent GSM blends; Châteauneuf-du-Pape is a benchmark for blend diversity and terroir-driven wines; oak usage tends to be lower than in Bordeaux.

  • Botrytis and Sauternes:

    • Noble rot (Botrytis cinerea) thrives where Ciron meets Dordogne/estuary moisture; Sauternes is the sought-after sweet wine region, with Château d’Yquem as the iconic top estate; Barsac can use its own name for its wines in addition to Sauternes.

  • Key winemaking concepts:

    • Oak usage (especially French oak) and aging in wood; duration often 1–2 years, with higher-end Bordeaux tending toward higher percentages of new oak.
    • Blending practices vary by region: explicit co-fermentation rules in Côte-Rôtie; Châteauneuf-du-Pape relies heavily on blended expressions from numerous varietals; the Right Bank’s blends emphasize Merlot and Cab Franc balance.

  • Regions to connect to broader topics:

    • Bordeaux’s market structure, the role of port access, and classification systems in shaping global demand.
    • Rhône’s climate-driven grape distribution and the nuanced differences between Northern and Southern styles.

  • Practical reminders:

    • Be mindful of mis-spellings in lecture notes (e.g., Condrieu, Châteauneuf-du-Pape, Château Grillet) and align with standard spellings for exam references where possible.
    • Distinguish between historical classification terms (Premier Cru Classé A, Grand Cru Classé A) and modern-day interpretations, which can shift with legal rulings and producer changes.

  • Note on live-session context (non-exam content):

    • The lecturer referenced rescheduling a tasting session and an informal exchange about student availability; these logistical details are not part of the wine content but reflect class management dynamics.
