Seven lines of arithmetic
Change any assumption you disagree with; the answer follows.
| Estimate actual drinkers | 25 guests × 80% drinking rate | 20 drinkers |
| Calculate base consumption | 20 drinkers × 1.5 drinks/hour × 4 hours | 120 base drinks |
| Apply consumption decay | Adjusted for drinking slowdown over time (decay factor: 3.25) | 98 adjusted drinks |
| Apply Thanksgiving modifier | × 1.3 (+30% for wine) | 127 wine servings if served alone |
| Share of the bar | 127 servings × 39.1% | 50 wine servings |
| Convert to bottles | 50 servings ÷ 5 servings per bottle | 10 bottles (raw) |
| Add 15% buffer & round up | 10 × 1.15 = 11.5, rounded up | 12 bottles |
The Knot's wedding guide plans one drink per guest per hour with a 50/25/25 liquor, beer and wine split. This model counts only the guests who drink, slows the pace after the first hour, and keeps a 15 percent margin; read the methodology.

Wine at a Thanksgiving
How much wine do I need for 25 guests?
You need 12 bottles of wine for 25 guests at a Thanksgiving, assuming you are serving a full bar. That is 50 servings with a 15% buffer. If wine is the only alcohol you serve, plan on 30 bottles instead.
How much wine per person for a Thanksgiving?
Plan for 2 servings of wine per person at a Thanksgiving with a full bar. This accounts for the fact that not everyone drinks alcohol, that consumption slows as the event progresses, and that wine is only 39.1 percent of what gets poured.
How many servings are in a bottle of wine?
One bottle of wine contains 5 servings. For 25 guests, you'll need 12 bottles to provide 50 total servings.
What percentage of the bar is wine at a Thanksgiving?
About 39.1 percent of the drinks poured at a Thanksgiving are wine. With 25 guests, roughly 20 will be drinking, and that share works out to 12 bottles.
Should I buy extra wine as a buffer?
Our figure of 12 bottles already includes a 15% buffer (2 extra bottles). That covers guests who drink more than average. It is always better to have leftovers than to run short.
How long will 12 bottles of wine last for 25 guests?
12 bottles of wine will last approximately 4 hours for 25 guests at a Thanksgiving, alongside the other drinks on the bar. This factors in the natural slowdown of consumption as the event progresses.
