Merlot follows the standard red wine process. The choices at each step decide whether you get a soft, fruity everyday bottle or a richer, oaked one.

The steps

Harvest: picked by hand or machine in mid to late autumn when the grapes are ripe.
Destemming and crushing: stems are removed, which lowers tannin and bitterness, and the grapes are crushed to release juice.
Fermentation: yeast turns sugar into alcohol over about one to two weeks. Stainless steel tanks are common; some winemakers use oak or concrete for added complexity. One guide gives 25 to 30 C (77 to 86 F) to keep fruit character. The skins stay in the tank to give color, tannin and flavor.
Maceration and pressing: skin contact time varies by style, then the wine is pressed.
Malolactic fermentation: a second fermentation that softens acidity, often in barrel, and can add a buttery feel.
Ageing: in steel, oak barrels or both, from a few months to several years. French oak adds vanilla, spice and toast; steel keeps fresh fruit.
Clarifying and bottling: the wine is stabilized and bottled.

What shapes the final wine

Choice	Effect
Stainless steel only	Fresh, fruity, drink-young style
Oak ageing	Vanilla, cocoa, smoky notes, more structure
Blending	Some makers add a more tannic grape such as Cabernet Sauvignon for structure
Long bottle age	Leather and tobacco notes in some wines

Alcohol and serving

Merlot usually lands between about 12 and 15% ABV; check the label. Serve slightly cool, around cellar temperature, with roast chicken, pork, pasta and mild cheeses.

Details vary by winery; examples here are typical, not a rule for every bottle.
