Merlot

Merlot is the grape that taught the wine world what soft means. Where Cabernet Sauvignon gives you grip and cedar and a decade of patience, Merlot gives you plush plum, black cherry, and a supple, welcoming texture almost from the off. It is the most-planted grape in Bordeaux and one of the most-planted red grapes on earth — and yet it spends most of its career being underrated, thanks in part to one grumpy character in a 2004 film.

The trick to learning Merlot is to hold two ideas at once: a core of ripe red and black fruit that shows up in every glass, and a dial — when the grower decides to pick — that swings the wine between two very different styles. Fix the core and understand the picking decision, and Merlot stops being "the soft one" and becomes a grape you can actually read.

The one thing to fix first: what Merlot is

Merlot is a natural Bordeaux cross of Cabernet Franc × Magdeleine Noire des Charentes — which makes it a half-sibling of Cabernet Sauvignon (they share Cabernet Franc as a parent). The Cabernet Franc link was shown by researchers at UC Davis in the late 1990s; the obscure mother grape, Magdeleine Noire des Charentes, was only pinned down by DNA analysis in the late 2000s, from old vines traced to Brittany. The name is thought to come from merle, the French for blackbird — the bird that liked eating the ripe grapes — and the grape was first recorded around 1784 in the Libournais, with the name "Merlot" appearing in print in 1824.

The grape itself explains the wine:

• Thinner skins, larger berries, looser bunches. Less skin relative to juice than Cabernet means softer tannins, less pigment, and a rounder texture.
• Earlier-ripening. Merlot ripens up to two weeks before Cabernet Sauvignon, so it succeeds where Cabernet would struggle to ripen — but in places that are too warm it can ripen too fast and turn flabby.
• Loves cold clay. It thrives on cool, water-retaining clay and limestone soils — above all the iron-rich clay of Pomerol — rather than Cabernet's warm gravel.
• A blender and a soloist. In Bordeaux it flesh-out blends with Cabernet Sauvignon and Cabernet Franc; in the New World it is very often bottled varietal.

The core profile — the same in every glass

Whatever the region, look for:

• Plum and black cherry — the signature fruit, in nearly every style
• Blackberry, mulberry, and cassis in riper examples
• Chocolate, mocha, vanilla, and coffee from oak aging
• Soft, supple tannins and medium acidity — the reason it drinks well young
• Round, plush, medium-to-full body

Two markers are conditional: picked early or grown in cooler spots, Merlot turns fresher and red-fruited (raspberry, strawberry) with leafy, herbaceous notes; picked late in warm sites it goes darker, jammier, and higher in alcohol.

Where it grows

Merlot is planted almost everywhere red wine is made. The benchmarks: Bordeaux (the Right Bank — Saint-Émilion and Pomerol, home of Château Pétrus), California (Napa and Sonoma), Chile (Colchagua's Apalta), and Washington State (Walla Walla, Red Mountain) — plus northern Italy (Friuli, the Veneto) and much of the rest of the wine world.
