How Much Wine to Pour?

Pouring wine looks simple until you see someone do it wrong. Too much, and the glass looks like a hostage situation. Too little, and it feels like you’re being punished for something. Somewhere between stinginess and flood lies the art of the proper pour - a small act of balance that says, “I know what I’m doing,” even if you rarely do.

The standard pour for still wine is about five ounces - roughly a third of a typical wine glass. That’s not an arbitrary number; it’s geometry and chemistry working together. Wine needs space, air, room to stretch and breathe. If you fill the glass to the rim, you smother the aromas and kill half the experience. The pleasure of wine isn’t in volume - it’s in the conversation between oxygen and scent, surface and swirl.

Professional tasters pour even less - two to three ounces - because tasting isn’t drinking. It’s inspection. You’re giving the wine a stage, not a bathtub. Sommeliers pour small so they can serve everyone evenly and watch how the wine evolves through the evening. The first glass should never be the same as the last; that’s the point.

But home life is not a sommelier exam. When you’re off the clock, rules soften like butter. The five-ounce pour is still a good baseline, but nobody’s measuring. If the night is short or the company long, pour what feels right—as long as you leave space in the glass. Even joy needs oxygen.

Different wines ask for different levels of generosity. Sparkling wine gets less - about four ounces - because bubbles climb better in tall, narrow glasses. Overpour, and you’ll lose the fizz before the first toast. Dessert wines get even less, maybe two ounces, because sweetness magnifies richness, and a small sip feels like enough. Fortified wines like Port or Sherry are poured in similarly small doses; they carry more alcohol and more story per inch.

Glass size is the biggest trickster of all. Modern glassware has grown absurd, like we’re trying to drink from goldfish bowls. A “standard” wine glass can hold twenty ounces or more, which makes a proper pour look stingy to the untrained eye. But that empty space is deliberate - it’s the stage for aroma. A good wine glass isn’t a container; it’s an amplifier.

Pouring, then, is less about quantity than intention. In a restaurant, it’s etiquette. At home, it’s rhythm. You pour to set the pace of the night. A small pour invites conversation. A heavy one says the talking’s over. Both have their moments.

Red, white, sparkling… Yes, they really ask to be poured differently—not because one is nobler than the other, but because their personalities demand different kinds of attention.

Reds need air - time and space to open, to show what’s hiding under the first impression. That’s why you pour them into larger glasses, usually no more than one-third full (about five ounces in a 15–20 ounce bowl). That generous air gap gives the wine a place to breathe, lets the volatile aromatics rise, the tannins soften, and the temperature settle. A red wine poured too high is like a singer trapped in a phone booth—no room for resonance.

White wines, by contrast, thrive on coolness and precision. Their aromas are often more fragile - floral, citrus, mineral - and they prefer a narrower glass to preserve chill and focus. You pour a little less, around four ounces, and that smaller volume helps the wine stay cold longer. White wines don’t need to wrestle with oxygen the way reds do; they’re more about clarity than evolution. Overpour them, and they warm up, flatten out, lose the brightness that makes them sing.

Temperature, too, dictates behavior. Red wines are often served around 60–65°F (16–18°C) - cooler than room temperature but not cold. They benefit from that slow oxygenation that starts the moment the bottle opens. Whites are served chilled, around 45–55°F (7–13°C)—and every degree above that robs them of freshness. Smaller pours mean you can refill often, keeping the experience crisp rather than tepid.

Then there’s the question of how to pour. Reds, especially older ones, should be poured slowly and steadily, with an eye on the sediment - don’t disturb it, don’t show off. Whites can be poured a little quicker; they’re cleaner, livelier, less temperamental. With sparkling wine, you tilt the glass and pour in stages, or risk reenacting a champagne commercial.

So: how much to pour? Enough to wake the wine, not drown it. Enough to taste the story, not end it. Wine, after all, is not rationed pleasure - it’s shared curiosity. A full bottle is just potential; the pour is where it becomes human. And if you still can’t remember the “right” amount - just pour until it looks beautiful. You’ll know when to stop. Just watch the rim of the glass.
