Wine Bottle Sizes and Glass Counts
The number of glasses per bottle depends on the bottle size and how much wine you pour. The standard 750ml bottle yields 5 glasses at 5 oz (150ml) per pour, which is the industry standard pour size. Restaurant pours are often 6 oz (175ml), giving 4 glasses per bottle. Knowing this helps you plan how many bottles to buy for a gathering without running short or over-buying.

Party Planning Guide
For a dinner party, plan on approximately 2–3 glasses of wine per guest. At a standard 5 oz (150ml) pour, 2 glasses per person means 300ml per guest. For 10 guests, that's 3,000ml — about 4 standard bottles. Always buy one or two extra for longer events or enthusiastic guests. For cocktail receptions, 1–2 glasses per person is usually sufficient.
Frequently Asked Questions
At the standard 5 oz (150ml) restaurant pour, a 750ml bottle yields exactly 5 glasses. If you pour 4 oz (120ml) for a tasting flight, you get 6 glasses. At a generous 6 oz (175ml) restaurant pour, the bottle gives about 4 full glasses.
No. Filling a wine glass one-third to half full leaves room to swirl the wine, which releases aromatic compounds and enhances flavor. Overfilling prevents swirling and makes the wine smell less expressive. A standard 5 oz pour in a 12–16 oz glass is ideal for most wine styles.
Opened wine kept sealed with a cork or wine stopper in the refrigerator lasts 3–5 days for still wine. Sparkling wine goes flat in 1–2 days. Fortified wines like port and sherry can last 2–4 weeks. Vacuum stoppers can extend shelf life slightly by removing oxygen from the bottle.
