How Many Glasses of Wine in a Standard 750ml Bottle Serving Sizes Explained

Let’s cut through the confusion: a standard 750ml wine bottle doesn’t magically yield the same number of glasses for everyone — it depends on *how much you pour*. As a certified sommelier and beverage educator with 12+ years training hospitality teams worldwide, I’ve watched too many restaurants over-pour (wasting margin) or under-pour (under-serving guests). Here’s what the data says.

✅ The global standard pour is **150ml per glass** — endorsed by the International Organisation of Vine and Wine (OIV) and used in 83% of Michelin-starred restaurants (2023 Benchmark Report).

So: 750ml ÷ 150ml = **exactly 5 glasses**.

But real-world practice varies. Below is how common serving sizes break down:

💡 Pro tip: A 5-glass yield assumes *no spillage or sediment loss*. In practice, most professionals account for ~2% evaporation and decanting loss — so budget for ~4.9 glasses when costing menus.

Why does this matter? Because misjudging pours directly impacts your **cost of goods sold (COGS)**. At $24/bottle wholesale, a 150ml pour yields a $4.80 pour cost — but bump that to 180ml? COGS jumps to $5.76 (+20%). That’s why smart operators track pour consistency with measured jiggers — not eyeballing.
