The Full Story
When you order a glass of wine at a restaurant, you are rarely getting a glass filled to the brim. The standard restaurant serve in Australia and the UK is exactly 150ml. In the United States, the standard pour is 5 fluid ounces, which translates to roughly 148ml.
If you are drinking at a pub in the UK, you might be offered different measures: a small glass (125ml), a standard glass (175ml), or a large glass (250ml). Because a standard bottle of wine holds 750ml, a 150ml pour means you will get exactly 5 glasses out of a single bottle.
The physical capacity of the glass itself is much larger. A typical wine glass holds between 250ml and 400ml of liquid. Champagne flutes are smaller, holding about 150ml in total, with a standard serve being 90 to 120ml. Dessert wines, which are much sweeter and higher in alcohol, are served in even smaller 75 to 100ml pours. Have you ever wondered why wine glasses are so large if you're only supposed to fill them a third of the way up? It all comes down to surface area and aroma.
Breakdown Table
| Type | Serve Size (ml) | Glass Capacity (ml) | Notes |
|---|---|---|---|
| Standard Serve (AU/UK) | 150 ml | 250–400 ml | Exactly 5 glasses per 750ml bottle. |
| Standard Serve (US) | 148 ml (5oz) | 250–400 ml | The American standard pour. |
| Pub Measures (UK) | 125 / 175 / 250 ml | 300–450 ml | Small, standard, and large pub options. |
| Champagne Flute | 90–120 ml | ~150 ml | Narrow shape preserves carbonation. |
| Dessert Wine | 75–100 ml | 120–150 ml | Smaller pour due to high sugar/alcohol. |
Did You Know?
A bottle is exactly 5 glasses. Because a standard wine bottle is 750ml, pouring exactly 150ml per glass yields a perfect 5 servings, making it easy for restaurants to calculate their margins.
The glass changes the taste. A wide-bowled Burgundy glass exposes delicate Pinot Noir to more oxygen, enhancing its aroma, while a taller, narrower Bordeaux glass directs bold Cabernet Sauvignon to the back of the tongue.
Calories scale quickly. A standard 150ml serve of dry wine contains about 120 to 130 calories. However, if you order a "large" 250ml glass at a pub, you are consuming 200 to 220 calories in a single drink.

Why the Shape of Your Glass Changes How Wine Tastes
It sounds like pretentious wine snobbery, but the shape of your glass genuinely alters the chemistry of what you are drinking. Wine is packed with volatile aromatic compounds. When you pour wine into a glass with a wide bowl, you increase the surface area of the liquid exposed to oxygen. This allows the wine to "breathe" and release its aromas.
This is why red wine glasses are generally larger and wider than white wine glasses. Bold reds need oxygen to soften their tannins. White wines, which are served chilled, use narrower glasses to minimize surface area, keeping the wine colder for longer and preserving delicate floral notes.
The famous glassware company Riedel conducted extensive experiments proving that the rim of the glass dictates where the wine first hits your tongue, highlighting either fruitiness or acidity. As a simple rule of thumb for home: use a large, wide bowl for heavy reds, a narrower U-shape for crisp whites, and a tall flute for anything with bubbles.
Frequently Asked Questions
How many glasses of wine are in a bottle?
A standard 750ml bottle contains exactly five 150ml servings.
What's the difference between a wine glass and a water glass?
Wine glasses have a stem to prevent your hand from warming the liquid, and a tapered bowl that traps and concentrates the aromatic compounds near your nose.
How much wine should I pour in a glass?
You should only fill a wine glass to about one-third or half of its total capacity. This leaves room in the bowl for the aromas to gather.
Does the shape of the glass really matter?
Yes. The shape dictates how much oxygen hits the wine and directs the liquid to specific parts of your palate, significantly altering the perceived taste and smell.
How many calories are in a glass of wine?
A standard 150ml glass of dry red or white wine contains approximately 120 to 130 calories.
