Seven lines of arithmetic
Change any assumption you disagree with; the answer follows.
| Estimate actual drinkers | 50 guests × 75% drinking rate | 38 drinkers |
| Calculate base consumption | 38 drinkers × 1.5 drinks/hour × 4 hours | 228 base drinks |
| Apply consumption decay | Adjusted for drinking slowdown over time (decay factor: 3.25) | 185 adjusted drinks |
| Apply March Madness party modifier | × 0.5 (-50% for wine) | 91 wine servings if served alone |
| Share of the bar | 91 servings × 13% | 12 wine servings |
| Convert to bottles | 12 servings ÷ 5 servings per bottle | 2.4 bottles (raw) |
| Add 15% buffer & round up | 2.4 × 1.15 = 2.8, rounded up | 3 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 March Madness party
How much wine do I need for 50 guests?
You need 3 bottles of wine for 50 guests at a March Madness party, assuming you are serving a full bar. That is 12 servings with a 15% buffer. If wine is the only alcohol you serve, plan on 21 bottles instead.
How much wine per person for a March Madness party?
Plan for 0.2 servings of wine per person at a March Madness party 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 13 percent of what gets poured.
How many servings are in a bottle of wine?
One bottle of wine contains 5 servings. For 50 guests, you'll need 3 bottles to provide 12 total servings.
What percentage of the bar is wine at a March Madness party?
About 13 percent of the drinks poured at a March Madness party are wine. With 50 guests, roughly 38 will be drinking, and that share works out to 3 bottles.
Should I buy extra wine as a buffer?
Our figure of 3 bottles already includes a 15% buffer (0 extra bottles). That covers guests who drink more than average. It is always better to have leftovers than to run short.
How long will 3 bottles of wine last for 50 guests?
3 bottles of wine will last approximately 4 hours for 50 guests at a March Madness party, alongside the other drinks on the bar. This factors in the natural slowdown of consumption as the event progresses.
