How many glasses are in a 750 ml bottle?

Typically, a standard 750ml bottle provides five 150ml (5 oz) glasses. However, this calculator lets you see how that number changes with different pour sizes.

How accurate is the calculator?

The calculator's math is precise. Its real-world accuracy depends on the consistency of your pours. Using the 'Waste/Buffer' slider can help account for small variations and spillage for a more realistic estimate.

Do sparkling wines use a different pour size?

Yes, often. Sparkling wine is typically served in smaller pours, around 120ml (4 oz), to preserve carbonation. We've included a 'Sparkling' preset for this.

Should I add a buffer for top-ups/spillage?

For events, it's highly recommended. The buffer accounts for the realities of serving: small spills, topping up a guest's glass, or a 'heavy' pour. A 10-15% buffer is a safe bet for most gatherings.

What are the common wine bottle sizes?

Split (187.5ml): ~1.25 glasses. Half/Demi (375ml): ~2.5 glasses. Standard (750ml): 5 glasses. Magnum (1.5L): 10 glasses. Double Magnum / Jeroboam (3.0L): 20 glasses.

What are typical pour sizes?

Tasting: 60-90ml (2-3 oz). Sparkling: 120ml (4 oz). Standard: 150ml (5 oz). Generous: 175-250ml (6-8.5 oz).

How long does an opened bottle stay fresh?

Still Wines (Red/White): 3-5 days if recorked and refrigerated. Sparkling Wines: Only 1-3 days, even with a proper stopper, as they lose carbonation quickly.

Understanding the Pour

The number of glasses is all about context. Here's a guide to common sizes and standards.

60-90 ml (2-3 oz)

Tasting Pour

Used at wineries or tastings to sample multiple wines without overconsumption. It's just enough to evaluate the aroma, flavor, and finish.

150 ml (5 oz)

Standard Restaurant Pour

This is the industry standard in many countries (like the U.S.) for a glass of wine. A standard 750ml bottle will yield exactly five 150ml glasses.

175-250 ml (6-8.5 oz)

Generous / Home Pour

Often used at home or in establishments offering larger serving sizes. In the UK, for example, 125ml, 175ml, and 250ml are common sizes.
