Red Wine Basics

Red wine begins with black grapes — the term used in winemaking for grapes with dark skins, ranging from deep purple to blue-black. Unlike white wine, red wine is made by fermenting the juice in contact with the grape skins, seeds, and sometimes stems. This process, called maceration, extracts color, tannins, and flavor compounds into the wine.

Tannins are polyphenolic compounds that create a drying, astringent sensation in your mouth — think of the feeling after drinking strong black tea. They come primarily from grape skins and seeds, though oak barrel aging adds additional tannins. Tannins provide structure, preserve the wine, and soften over time, which is why age-worthy red wines often have high tannin levels initially.

Red wines are categorized by body — the weight and fullness you perceive in your mouth. Light-bodied reds like Pinot Noir feel delicate and translucent. Medium-bodied wines like Merlot or Sangiovese offer more weight. Full-bodied reds like Cabernet Sauvignon or Syrah feel rich and coating. Body comes from alcohol level, tannin concentration, and residual sugar.

The five major red wine styles every bartender should know:

• Light & Fruity: Pinot Noir, Gamay (Beaujolais). Low tannin, bright acidity, red fruit flavors. Serve slightly chilled (12-15°C).
• Medium & Smooth: Merlot, Grenache. Soft tannins, medium body, approachable. The crowd-pleasers.
• Bold & Structured: Cabernet Sauvignon, Nebbiolo. High tannin, full body, black fruit, needs food or age.
• Spicy & Savory: Syrah/Shiraz, Tempranillo. Peppery notes, medium-to-full body, dark fruit with herbal undertones.
• Earthy & Complex: Sangiovese (Chianti), Pinot Noir (Burgundy). High acidity, dried fruit, leather, tobacco notes.

Acidity in red wine provides freshness and makes wine food-friendly. Wines from cooler climates (Burgundy, Oregon) typically have higher acidity than those from warm regions (Napa, Barossa Valley). When recommending red wine, consider the guest's food choice: high-tannin wines pair with fatty proteins, while high-acid wines cut through rich sauces.
