A standard 750ml bottle of wine gives you 5 glasses — based on a 5oz (150ml) pour. But that number shifts depending on how generously you pour, what type of wine you’re serving, and the size of your glasses.
If you’re planning a dinner party, buying wine as a gift, or just trying to figure out how far one bottle will go, this guide covers everything you need to know.
The Quick Answer: Glasses Per Bottle
Here’s the breakdown at a glance:
| Pour Size | Glasses Per 750ml Bottle |
| 3 oz (90ml) — tasting pour | ~8 glasses |
| 4 oz (120ml) — restaurant pour | ~6 glasses |
| 5 oz (150ml) — standard pour | ~5 glasses |
| 6 oz (180ml) — generous pour | ~4 glasses |
The 5oz pour is the standard used by sommeliers, restaurants, and the wine industry worldwide. It’s also what most calorie counts and alcohol measurements are based on.
Why 750ml? The History of the Standard Wine Bottle
The 750ml wine bottle has been the industry standard since the 19th century. The most practical reason? It’s roughly the volume a glassblower could produce in a single breath.
Today, 750ml (about 25.4 oz) remains universal across virtually all still wines — red, white, and rosé. It’s the size you’ll find on restaurant wine lists, at retail stores, and in Amazon wine deals.

How Glass Size Changes Everything
One of the biggest variables isn’t the bottle — it’s your glass.
Modern wine glasses are designed to be filled only one-third to half full. This isn’t stinginess. The empty space allows the wine to breathe and concentrate its aromas, which is essential for tasting wine properly.
Red Wine Glasses
Red wine glasses tend to be larger — often 18-22oz capacity. A 5oz pour in a big Bordeaux glass looks almost empty. Hosts often over-pour as a result, reducing the number of glasses per bottle to 4 or even 3.
White Wine Glasses
White wine glasses are smaller — typically 12-16oz. A standard 5oz pour fills them more visibly, making it easier to stick to the correct portion.
Sparkling Wine / Champagne Flutes
Flutes are narrow by design, which preserves the bubbles. A standard pour in a flute is also around 4-5oz, though the tall shape makes it look like more. From a 750ml bottle of Champagne or Prosecco, you’ll get 5-6 pours.
Wine Bottle Sizes: From Piccolo to Nebuchadnezzar
Not all wine comes in a 750ml bottle. Here’s how many glasses you get from each standard bottle size:
| Bottle Name | Size | Standard Glasses (5oz) |
| Piccolo / Split | 187.5ml | ~1 glass |
| Demi / Half | 375ml | ~2–3 glasses |
| Standard | 750ml | ~5 glasses |
| Magnum | 1.5L | ~10 glasses |
| Jeroboam (Champagne) | 3L | ~20 glasses |
| Double Magnum | 3L | ~20 glasses |
| Rehoboam | 4.5L | ~30 glasses |
| Methuselah / Imperial | 6L | ~40 glasses |
| Salmanazar | 9L | ~60 glasses |
| Balthazar | 12L | ~80 glasses |
| Nebuchadnezzar | 15L | ~100 glasses |
Planning a party? A Magnum (1.5L) is a great choice — it holds the equivalent of two standard bottles, ages slightly better, and makes an impressive centrepiece on the table.
How Many Calories in a Glass of Wine?
Since 5oz is the standard pour, calorie counts are based on this serving size:
| Wine Type | Calories per 5oz Glass |
| Sparkling (Brut) | ~95 kcal |
| Dry white (e.g. Sauvignon Blanc) | ~120 kcal |
| Dry rosé | ~125 kcal |
| Dry red (e.g. Pinot Noir) | ~125 kcal |
| Full-bodied red (e.g. Cabernet Sauvignon) | ~135 kcal |
| Sweet white (e.g. Riesling Spätlese) | ~165 kcal |
| Fortified (e.g. Port) | ~185 kcal |
Alcohol content is the biggest driver of calories in wine. A light-bodied 11% ABV white will always have fewer calories than a big 15% Californian Cabernet.

How Many Units of Alcohol in a Bottle of Wine?
In the UK and many countries, alcohol is measured in units. One unit = 10ml of pure alcohol.
For a standard 750ml bottle at 13% ABV (typical for most table wines):
750ml × 13% ABV = 9.75 units per bottle
Per 5oz (150ml) glass at 13% ABV = ~2 units
The NHS recommends no more than 14 units per week for adults — that’s roughly one and a half standard bottles spread across the week.
How to Calculate Glasses for a Party
Use this simple formula:
Glasses needed = (guests × glasses per person) ÷ 5
Example: Dinner party for 8 people, 3 glasses each
- Total glasses needed: 8 × 3 = 24 glasses
- Bottles needed: 24 ÷ 5 = 4.8 → round up to 5 bottles
General rule of thumb for events:
- Cocktail hour (1 hour): 1 bottle per 3 guests
- Dinner (2 hours): 1 bottle per 2 guests
- Full evening (3+ hours): 1 bottle per 1–1.5 guests
Always buy slightly more than you think you need — an unopened bottle is easy to return or enjoy another night.

FAQ
How many glasses of wine are in a 750ml bottle?
A standard 750ml bottle of wine contains 5 glasses, based on a 5oz (150ml) pour — the industry standard. If you pour more generously (6oz), you’ll get about 4 glasses. A tasting pour (3oz) gives you up to 8 glasses per bottle.
How many ounces are in a bottle of wine?
A standard 750ml wine bottle contains 25.4 fluid ounces of wine.
How many glasses in a bottle of champagne or prosecco?
A 750ml bottle of Champagne, Prosecco, or Cava gives you 5–6 glasses, as sparkling wine is typically poured in slightly smaller amounts (4–4.5oz) to preserve the bubbles.
How many glasses in a Magnum?
A Magnum is 1.5 litres — double the standard bottle — so it contains 10 glasses at a 5oz pour.
How many glasses in a box of wine?
A standard 3-litre wine box (the most common size) contains the equivalent of 4 standard bottles, giving you approximately 20 glasses at a 5oz pour.
Is a glass of wine a day bad for you?
Current guidance from most health organisations is that there is no completely “safe” level of alcohol consumption. Moderate consumption (1 glass per day) is associated with certain health benefits in some studies, but the WHO and many national health bodies emphasise that the safest choice is to drink as little as possible. Always check the latest guidance in your country.
