Seven lines of arithmetic
Change any assumption you disagree with; the answer follows.
| Estimate actual drinkers | 125 guests × 70% drinking rate | 88 drinkers |
| Calculate base consumption | 88 drinkers × 1.5 drinks/hour × 5 hours | 660 base drinks |
| Apply consumption decay | Adjusted for drinking slowdown over time (decay factor: 3.75) | 495 adjusted drinks |
| Apply wedding modifier | × 1.2 (+20% for wine) | 591 wine servings if served alone |
| Share of the bar | 591 servings × 37.5% | 222 wine servings |
| Convert to bottles | 222 servings ÷ 5 servings per bottle | 44.4 bottles (raw) |
| Add 15% buffer & round up | 44.4 × 1.15 = 51.1, rounded up | 52 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 wedding
How much wine do I need for 125 guests?
You need 52 bottles of wine for 125 guests at a wedding, assuming you are serving a full bar. That is 222 servings with a 15% buffer. If wine is the only alcohol you serve, plan on 136 bottles instead.
How much wine per person for a wedding?
Plan for 1.8 servings of wine per person at a wedding 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 37.5 percent of what gets poured.
How many servings are in a bottle of wine?
One bottle of wine contains 5 servings. For 125 guests, you'll need 52 bottles to provide 222 total servings.
What percentage of the bar is wine at a wedding?
About 37.5 percent of the drinks poured at a wedding are wine. With 125 guests, roughly 88 will be drinking, and that share works out to 52 bottles.
Should I buy extra wine as a buffer?
Our figure of 52 bottles already includes a 15% buffer (7 extra bottles). That covers guests who drink more than average. It is always better to have leftovers than to run short.
How long will 52 bottles of wine last for 125 guests?
52 bottles of wine will last approximately 5 hours for 125 guests at a wedding, alongside the other drinks on the bar. This factors in the natural slowdown of consumption as the event progresses.
