The 2015 Bordeaux vintage is widely regarded as one of the best of the modern era, delivering wines with intensity, balance, and superb aging potential. A warm and dry growing season, followed by a near-perfect harvest, created wines that exhibit ripe fruit, polished tannins, and excellent structure, making them ideal for both drinking now and long-term cellaring.
Auriane d'Aramon, our Head Wine Buyer, says "Bordeaux’s 2015 vintage is all about richness and charm—smooth, ripe, and easy to love, with a warmth that makes it immediately appealing. 2015 was a fantastic year, producing wines that are lush and inviting."
The Growing Season: Climate Conditions and Impact on the Vines
The 2015 growing season in Bordeaux was marked by textbook conditions, ensuring optimal phenolic ripeness across both the Left Bank and Right Bank.
What is Phenolic Ripeness and Why Does it Matter?
Phenolic ripeness refers to the development of compounds in the grape skins, seeds, and stems, including tannins (which give wine structure and mouthfeel) and anthocyanins (which provide colour). Achieving full phenolic ripeness means that the grapes develop balanced flavours, tannins, and acidity, crucial for high-quality wine production.
Winter & Spring: Early Start with Healthy Bud Break
-
The winter of 2014-2015 was mild and wet, replenishing groundwater reserves essential for the vines to withstand the summer heat.
-
Bud break (the moment vines begin to sprout new growth) occurred early in late March, setting the stage for a healthy growing cycle.
-
A dry and warm April accelerated vine development, leading to an even and problem-free flowering in May, which is key to ensuring good grape yield.
Summer: Warm & Dry, With Key Rainfall in August
-
June and July saw consistently hot temperatures, promoting small, concentrated berries (a good sign for wine complexity and flavour concentration).
-
The absence of excessive heat waves prevented sunburn or shriveling of the grapes, which can lead to overly jammy or unbalanced wines.
-
August rainfall arrived at the perfect time, preventing hydric stress (when vines struggle to find enough water), maintaining acidity, and allowing for gradual ripening.
Harvest: Ideal Conditions for Balanced Maturity
-
September was warm and dry, allowing winemakers to harvest at full phenolic ripeness.
-
The lack of heavy rains during harvest meant that grapes were picked at optimal sugar and acidity levels, avoiding dilution of flavours.
-
Estates had the luxury of choosing when to pick, which is a significant advantage in achieving the best possible quality.
Left Bank vs. Right Bank: Key Differences in 2015 Wines
The vintage favoured both Cabernet Sauvignon on the Left Bank and Merlot on the Right Bank, creating wines that balance concentration, freshness, and structure.
Left Bank (Médoc & Graves) – Cabernet Sauvignon Dominance
The Left Bank, home to Pauillac, Saint-Julien, and Margaux, is known for its gravelly soils, which drain well and allow Cabernet Sauvignon to thrive. This grape produces wines with firm tannins (giving the wine structure and aging ability), deep black fruit flavours, and excellent longevity.
-
The hot and dry summer particularly benefited Cabernet Sauvignon, leading to wines with deep colour, firm tannins, and aging potential of 20+ years.
-
Pauillac and Saint-Julien performed exceptionally well, producing structured, classically-styled Bordeaux with excellent length.
-
Notable wines include Château Latour, Château Margaux, and Château Léoville Las Cases, all of which have received exceptional scores from critics.
Right Bank (Saint-Émilion & Pomerol) – Opulent Merlot-Based Wines
The Right Bank, famous for Saint-Émilion and Pomerol, features limestone and clay-rich soils that retain more moisture. This allows Merlot to dominate, producing wines with softer tannins, plush textures, and ripe, expressive fruit flavours.
-
Merlot thrived in the 2015 conditions, delivering wines with silky tannins, rich black fruit, and layered complexity.
-
Pomerol and Saint-Émilion excelled, producing some of the most opulent and approachable wines of the vintage.
-
Château Cheval Blanc, Château Angélus, and Château Pétrus crafted some of the most collectible wines of the year.
The Science Behind the Balance: Tannin, Acidity & Aging Potential
What Are Tannins?
Tannins are naturally occurring compounds found in grape skins, seeds, and stems. They create the dry, slightly astringent sensation in red wines and are crucial for structure and aging potential. Wines with high tannin content, like those from the Left Bank, can evolve for decades, developing smoother textures and complex flavours over time.
The Role of Acidity
Acidity is what gives wine freshness and vibrancy. A wine with too little acidity can taste flat, while a well-balanced level ensures longevity and food-friendliness. The 2015 Bordeaux vintage maintained excellent acidity despite the warm summer, ensuring the wines remain bright and structured rather than overly heavy.
Investment Potential: A Vintage Built to Last
✔ Already showing beautifully – Many wines are approachable now, but top estates will reward further aging.
✔ Strong aging potential – Some classified growths can cellar for 30+ years.
✔ Highly rated across the board – Considered one of the best modern vintages by wine critics and collectors.
✔ Exceptional balance of fruit, tannin, and acidity – A hallmark of longevity in fine Bordeaux.
Final Thoughts: Why 2015 is a Collector’s Dream
With its near-perfect growing season, wines that showcase power and elegance, and a balance of structure and freshness, the 2015 Bordeaux vintage is a must-have for any serious wine lover or investor.
