About Merlot

Merlot is the most widely planted grape in Bordeaux and produces some of the world's most celebrated and expensive wines in Pomerol and Saint-Émilion. Its name derives from the French word for blackbird (merle), possibly because the birds love its sweet, early-ripening berries.

Compared to Cabernet Sauvignon, Merlot produces softer, rounder wines with lower tannins and earlier drinkability. Its thin skin and larger berries contribute to its supple, velvety texture. The grape thrives in clay soils where it can retain moisture during dry periods.

After being dismissed in the 1990s (notably in the film "Sideways"), Merlot has regained appreciation as producers focus on quality over quantity. The finest examples from Pomerol's Château Pétrus and Le Pin rank among the world's most expensive wines.

The Nose

Merlot’s aroma is immediately inviting, bursting with primary notes of ripe red plum and juicy black cherry, often evolving to include hints of raspberry as well. With age, secondary aromas of cocoa, vanilla, and cedar develop from oak influence, leading to tertiary notes of dried fig, tobacco, and earthy undertones in more mature examples. The overall impression is one of plush fruit balanced by subtle complexity, varying from bright and fresh to rich and decadent depending on the climate and winemaking style.

The Palate

Merlot wines typically offer a medium-bodied experience with soft, velvety tannins and balanced acidity, creating a smooth mouthfeel. The flavor profile is dominated by ripe red and black fruit – think plum, cherry, and blackberry – often layered with notes of chocolate, vanilla, or a subtle herbal quality. Depending on the climate, these wines can range from fresh and red-fruited to richer and more concentrated with baked fruit and mocha undertones.

Viticulture

Climate:
Merlot thrives in moderate climates. It's less tolerant of extreme cold than Cabernet Sauvignon but more tolerant of warmer conditions.
Training Systems:
Vertical Shoot Positioning (VSP), Guyot, Cordon-trained systems
Yield:
Average yield is 5-8 tonnes per hectare (2-3.2 tonnes per acre), but can vary significantly depending on vineyard management and climate.
Brix Level:
Typically 22-25 Brix at harvest.
Common Issues:
Powdery mildew, Downy mildew, Botrytis bunch rot (especially in wet years), Black rot, Leafroll viruses, Frost damage (early budburst), Bird predation
Considerations:
Pruning severity impacts yield and berry characteristics. Moderate pruning generally yields better quality.
Drainage:
Excellent drainage is crucial to prevent root rot.
Indicators:
Berry flavor development, tannin ripeness, sugar levels (Brix), and acidity are key indicators. Seed color (turning from green to brown) is also used.
Pest Management:
Integrated Pest Management (IPM) strategies are recommended to minimize pesticide use.
Ph:
6.0-7.0 (slightly acidic to neutral)
Row Orientation:
Row orientation can influence sun exposure and air circulation. Generally, rows are oriented to maximize sunlight interception.
Soil Depth:
Moderate to deep soil profiles are beneficial.
Timing:
Typically late September to October in the Northern Hemisphere, and February to March in the Southern Hemisphere.
Type:
Spur pruning is common, allowing for controlled crop load.
Vine Density:
Typically 2,500-4,000 vines per hectare (1,000-1,600 vines per acre). Higher density can be used for quality-focused production.

Region Map

Old World vs New World

Understanding regional style differences helps identify origin in blind tasting.

🏰 Old World (Europe)

  • Plum and red fruit dominant
  • Earthy, truffle notes (especially Pomerol)
  • Firm but velvety tannins
  • Moderate alcohol levels
  • More structure and ageability
  • Terroir complexity

🌎 New World (Americas, Australasia)

  • Richer, jammier fruit
  • Chocolate, mocha oak notes
  • Softer, plusher texture
  • Higher alcohol, sometimes sweeter
  • More immediately appealing
  • Can lack acidity/structure

Key Tells for Blind Tasting

Earthy, savoury complexity with firm structure = Bordeaux. Plush, chocolatey, soft wine with obvious fruit sweetness = New World, likely California or Chile.

Similar Grapes & Lateral Confusion

These grapes are commonly confused with Merlot in blind tasting. Here's how to tell them apart:

Cabernet Sauvignon

Why confused: Both Bordeaux varieties with dark fruit character and often blended together. Both Bordeaux varieties with similar colour depth.

How to distinguish: Cabernet Sauvignon: Cab Sauv has CASSIS (blackcurrant) vs plum in Merlot. Cab Sauv has higher, grippier tannins. Merlot is softer, rounder, more approachable.
Merlot: Merlot has PLUM fruit (vs cassis). Softer, velvety tannins. More chocolate notes. Earlier-drinking.
Compare side by side →

Carménère

Why confused: Historically confused in Chile; similar body and texture. Were confused for over a century in Chile!

How to distinguish: Merlot: Merlot lacks the distinctive green bell pepper. Carménère is more herbaceous. Merlot is plummier and rounder.
Carménère: Carménère has distinctive GREEN BELL PEPPER. Merlot is plummy without vegetal notes.
Compare side by side →

Tempranillo

Why confused: Similar plum fruit and soft tannins.

How to distinguish: Tempranillo: Tempranillo shows leather, tobacco, and distinctive oak character. Merlot is rounder without the savoury complexity.
Compare side by side →

Blind Tasting Tips

Colour: Medium-deep ruby; develops brick/orange rim earlier than Cabernet.

Key markers: Plum dominates over cassis. Look for softer, more approachable tannins. Often has a distinct chocolate note.

Structure: Medium tannins with a velvety texture. Medium acidity. Medium-full body but rounder than Cabernet.

Common confusions: Cabernet Sauvignon (higher tannins, cassis), Cabernet Franc (more herbaceous, lighter).

Vintage History

Notable vintages for Merlot:

2023
A cool and wet spring delayed budburst, but a warm, dry summer allowed for excellent fruit development. Moderate temperatures throughout August and September preserved acidity and vibrant fruit flavors. Harvest began in mid-September. The resulting Merlot is deeply colored with notes of black cherry, plum, and a hint of cocoa. Well-structured tannins suggest good aging potential. Overall, an excellent vintage for Merlot in Napa Valley.
2022
2022 was a remarkably warm and dry vintage in Bordeaux. Early budburst and flowering were followed by a prolonged heatwave in July. Veraison occurred early. Despite the heat, careful canopy management helped preserve acidity. Harvest was the earliest on record, beginning in late August. The Merlot exhibits ripe, concentrated flavors of black fruit, chocolate, and spice. Tannins are plush and well-integrated. A powerful and opulent vintage, best enjoyed young to medium-term.
2021
A challenging vintage marked by a late spring frost that significantly reduced yields in some areas. The summer was hot and dry, leading to water stress for vines. However, careful irrigation and canopy management mitigated the worst effects. Harvest occurred in late October. The Merlot displays concentrated flavors of blackberry and cassis, with firm tannins and a balanced acidity. A good, but not exceptional, vintage requiring careful selection.
2020
A near-perfect growing season. Consistent warm days and cool nights allowed for slow, even ripening. The absence of major heat spikes or rainfall resulted in exceptional fruit quality. Harvest took place in early October. The Merlot is characterized by lush flavors of red plum, raspberry, and vanilla. Silky tannins and a long, elegant finish. An outstanding vintage with excellent aging potential.
