Merlot, Cabernet

History and terroir: from Bordeaux to the world

Merlot originates from the Bordeaux region of south-western France. Its name appears to derive from “merle”, the blackbird, perhaps because of the dark colour of the berries or these birds' appetite for ripe grapes. Its genetic origins link it to Cabernet Franc and an ancient Bordeaux variety called Magdeleine Noire des Charentes. It is therefore part of the great family that also gave rise to Cabernet Sauvignon and Carménère.

The grape's international spread is due to its good adaptability and relatively early ripening. Compared with Cabernet Sauvignon, Merlot reaches maturity earlier: an important advantage in areas with cool or rainy autumns. However, it requires attention, as it can lose freshness and precision if harvested too late, especially in warm climates. Its ideal habitat combines sufficient warmth with soils able to retain water without causing waterlogging.

The vineyard and the style of Merlot wines

Merlot particularly favours clay soils that are cool and fairly deep. Clay tends to slow ripening and retain moisture in dry seasons, helping the grape variety express more nuanced aromas and a fine tannic texture. On gravelly, well-drained soils, it can instead take on a more structured profile, often in dialogue with Cabernet Sauvignon and Cabernet Franc, as happens in many areas on Bordeaux's left bank.

When young, a well-made Merlot often evokes plum, black cherry, blackberry, ripe redcurrant and violet. With evolution, notes of cocoa, sweet tobacco, undergrowth, leather, graphite and spices may emerge. On the palate, it is usually medium- to full-bodied, with moderate acidity and rounded tannins. Small oak barrels, when used judiciously, can broaden the wine with hints of cedar, vanilla, toast or coffee; when excessive, however, they mask the fruit and weigh down the palate.

Bordeaux: Pomerol, Saint-Émilion and great blends

In Bordeaux, Merlot finds one of its most authoritative expressions, particularly on the right bank of the Dordogne. In Pomerol, it often dominates blends and achieves an extraordinary combination of density, finesse and aromatic depth. Here, the clays, rich in iron in certain areas, favour full-bodied yet not necessarily heavy wines, with dark fruit, spices, earthy notes and a highly harmonious evolution.

Saint-Émilion is also a key territory for Merlot, frequently complemented by Cabernet Franc. Soils vary greatly: limestone and clay on the plateaux, sand and gravel in lower areas. The result is different interpretations, from more floral and taut versions to rich and creamy styles. On the left bank, in the Médoc and Graves, Merlot is often the partner that softens Cabernet Sauvignon: it brings flesh, colour and approachability to classic Bordeaux blends.

Merlot in Italy and major international regions

In Italy, Merlot has found a second home particularly in the north-east. In Friuli-Venezia Giulia, it can produce elegant reds with clear fruit, aromatic herbs and often surprising freshness; in hilly areas and on ponca soils, an alternation of marl and sandstone, it gains drive and precision. In Veneto and Trentino-Alto Adige, interpretations range from everyday, smooth and fruity reds to more ambitious versions aged in wood.

In Tuscany, it is a leading variety both on its own and in blends with Sangiovese or Cabernet. In warmer coastal areas, it tends to be ripe, enveloping and Mediterranean; in inland or high-altitude areas, it can retain greater tension. Merlot is also important in Ticino, where vineyards often benefit from favourable diurnal temperature variation, and in the New World. In California it produces broad, ripe wines; in Chile it often retains a fresh, balsamic streak, while in some high-altitude Argentine areas it can combine intense fruit with good acidity.

How to serve it and pair it at the table

Temperature is crucial. A simple, young Merlot shows well at around 16 °C, while a structured version aged in barrel or with a few years in bottle can be served between 17 and 18 °C. I would avoid higher temperatures: warmth accentuates the alcohol and makes the wine seem softer and flabbier. A generously sized red wine glass with a not overly wide opening helps capture both the fruit and the evolved notes.

Not all Merlots require decanting. A young, fruity wine can be opened shortly before serving; an important bottle that is very closed or has sediment, on the other hand, benefits from gentle decanting for thirty minutes to an hour. At the table, it is an extremely versatile grape variety: it pairs well with roast meats, braised dishes that are not excessively sweet, mushrooms, flavourful legumes and medium-aged cheeses. With a fresher Merlot, I would choose less elaborate dishes; with a rich, ripe one, more succulent and structured fare.
