Wine Serving Size Calculator

Pouring the right amount of wine for a gathering takes a little planning. Too little and guests go thirsty. Too much and you have opened bottles going to waste.

Standard wine facts:

• A standard wine bottle holds 750 mL.
• A standard glass pour is 150 mL (5 oz): giving 5 glasses per bottle.
• A generous pour is 175 mL (6 oz): giving about 4 glasses per bottle.
• A tasting pour is 90 mL (3 oz): giving about 8 pours per bottle.

Larger bottle formats:

• A Magnum (1.5 L) = 10 standard glasses.
• A Double Magnum (3 L) = 20 standard glasses.
• Magnums are great for dinner parties: they age better and make an impression.

Typical consumption by event type:

• Dinner party: 2–3 glasses per person. Wine accompanies the meal.
• Casual gathering: 1–2 glasses per person. Lighter drinking, more socialising.
• Wine tasting: 3–4 small pours per person across multiple bottles.
• Celebration / toast: 1 glass per person. Just enough for the moment.

The 1-bottle-per-2-guests rule of thumb: For a dinner party, plan one 750 mL bottle per 2 guests as a starting point. For a 3-hour+ event with wine-loving guests, budget closer to 1 bottle per guest.

Wine and temperature:

• Red wine: 16–18°C (61–64°F), slightly below room temperature. Do not serve warm.
• White wine: 8–12°C (46–54°F), well chilled but not ice cold.
• Sparkling wine / Champagne: 6–8°C (43–46°F), well chilled throughout serving.

Red vs. white split: For mixed gatherings, a 60% red / 40% white split works well in most settings. Adjust based on the season: more white in summer, more red in winter.

Always have at least one extra bottle on hand — it is better to have a spare than to run short.
