Calculating Your Wine Servings
Calculating the number of drinks in two bottles of wine is a crucial skill for anyone planning a dinner party or enjoying a quiet evening. While a simple calculation might suggest 10 drinks, the reality is more nuanced. Factors like the wine's alcohol by volume (ABV), the size of your pour, and even the type of wine glass you use can all change the final count.
The Standard Calculation
A standard wine bottle holds 750ml, which is approximately 25.4 fluid ounces. The accepted standard serving size for a glass of wine in the United States is 5 fluid ounces. By this math, a single standard bottle yields five servings.
$$(25.4 \text{ oz}) / (5 \text{ oz per glass}) \approx 5 \text{ glasses}$$
Therefore, two standard 750ml bottles would contain roughly 10 standard 5-ounce servings.
Why Your Drink Count Might Differ
1. Alcohol by Volume (ABV)
Not all wines are created equal. The ABV, or alcohol percentage, is printed on the label and can significantly impact how many standard drinks are actually in a bottle. A standard drink in the US is defined as containing 14 grams of pure alcohol.
- Light white wines (9-11% ABV): Wines like Riesling or Moscato might yield closer to 4 to 4.5 standard drinks per bottle. For two bottles, this means 8-9 standard drinks.
- Standard reds and whites (12-13.5% ABV): Most common wines, such as Chardonnay or Merlot, will fall into the typical 5 to 5.5 standard drinks per bottle range. For two bottles, this is about 10-11 standard drinks.
- Bolder reds (14-15% ABV): Robust wines like Zinfandel or Shiraz are more potent, containing closer to 5.8 to 6 standard drinks per bottle. Two bottles could contain up to 12 standard drinks.
- Fortified wines (17-20% ABV): Port or Sherry have a much higher alcohol content. A single 750ml bottle could contain 7 to 8 or more standard drinks. Two bottles of these wines would provide a much higher number of total standard drinks, requiring a smaller pour.
2. The Art of the Pour
While a 5-ounce serving is the standard, personal pouring habits often differ. A generous home pour might easily be 6 or 7 ounces, reducing the total number of glasses from each bottle. Many restaurants also offer different pour sizes, from a small 125ml pour to a large 250ml pour.
3. Glass Shape and Size
The shape of your wine glass can also influence your perceived pour size. Red wine glasses often have a wider bowl to allow for aeration, making a standard 5-ounce pour look smaller. Sparkling wine, on the other hand, is typically served in a tall, narrow flute that holds a smaller volume, sometimes just 4 ounces.
Comparison Table: Standard Drinks in Two Bottles by Wine Type
This table illustrates the difference in the number of standard 5-ounce drinks you can expect from two 750ml bottles, depending on the wine's ABV.
| Wine Type | Typical ABV Range | Standard Drinks per Bottle | Standard Drinks in 2 Bottles | 
|---|---|---|---|
| Light White | 9–11% | ~4–4.5 | ~8–9 | 
| Standard Red/White | 12–13.5% | ~5–5.5 | ~10–11 | 
| Bolder Red | 14–15% | ~5.8–6 | ~11–12 | 
| Fortified | 17–20% | ~7–8+ | ~14–16+ | 
Planning for your event
To accurately plan for your event, consider both the number of guests and their potential consumption habits. For a larger gathering, estimating based on a higher number of servings per person, perhaps 2-3 standard drinks, is a safe approach. For a more formal dinner where smaller, more precise pours are used, you can stick closer to the standard 10-drink estimate for two bottles. This level of planning is essential for ensuring your guests have enough to drink without running out unexpectedly.
Conclusion
While the simple answer to how many drinks are in two bottles of wine is 10, this is only a starting point. The final number of standard drinks depends on several variables, including the wine's alcohol content and the actual serving size. For light wines, you can expect slightly fewer standard drinks, while bolder reds or fortified wines contain significantly more alcohol per bottle, meaning fewer glasses of the same volume are required. Always check the ABV on the label to make the most accurate calculation for your needs. Remembering that a standard 5-ounce pour is the basis for this estimate is key to responsible serving and enjoyment.

What to know before you pour
- Standard Size: Two standard 750ml bottles of wine typically contain 10 drinks based on a 5-ounce (150ml) pour.
- ABV Matters: The wine's alcohol by volume (ABV) affects the number of standard drinks per bottle; higher ABV wines have more.
- Pour Size: Personal and restaurant pour sizes vary, which directly impacts the number of glasses you'll get from two bottles.
- Wine Type: Lighter wines yield fewer standard drinks per bottle than bolder or fortified wines, which are served in smaller portions due to higher alcohol content.
- Planning: For events, always account for varying consumption habits by estimating slightly more wine than the standard calculation suggests.
FAQs
Q: Is a bottle of wine considered 10 drinks? A: No, a standard 750ml bottle of wine is typically considered to be five 5-ounce servings, not 10. Two bottles, however, would be about 10 standard servings. The actual number of standard drinks can vary based on ABV.
Q: What is the average pour size for wine? A: The standard pour size for a glass of wine in the US is 5 fluid ounces (150ml). Some restaurants may offer smaller (125ml) or larger (175ml or 250ml) servings.
Q: Do fortified wines like Port have more drinks? A: Yes, because fortified wines have a higher ABV, they are served in smaller portions, meaning you get more servings out of a 750ml bottle. For example, a 3-ounce pour for Port would yield more servings than a 5-ounce pour of table wine.
Q: Does a magnum bottle contain 10 drinks? A: A magnum bottle is 1.5 liters, which is double the size of a standard 750ml bottle. With a standard 5-ounce pour, a magnum would contain approximately 10 glasses.
Q: How many bottles of wine do I need for a party? A: A common rule of thumb is to estimate about 2-3 standard drinks per person over an evening. For a party with moderate drinkers, planning for two bottles per 3-4 people is a safe starting point, though this should be adjusted for individual group habits.
Q: What is ABV? A: ABV stands for Alcohol by Volume, which is a standard measure of how much alcohol is contained in a given volume of an alcoholic beverage. It is expressed as a percentage and is listed on the wine label.
Q: How can I accurately count my drinks? A: To accurately count your drinks, always check the ABV on the bottle label. Pacing yourself and using a measured pour (e.g., a wine glass with a fill line) can also help you track your consumption more accurately.
Q: How does a higher ABV affect the number of standard drinks? A: Wines with a higher ABV, such as a bold red at 15%, contain more alcohol per ounce. This means that a standard 5-ounce pour of a higher ABV wine is equivalent to more than one standard drink, effectively reducing the number of standard drinks you can get from the bottle before reaching your alcohol limit.
