Seven lines of arithmetic
Change any assumption you disagree with; the answer follows.
| Estimate actual drinkers | 30 guests × 80% drinking rate | 24 drinkers |
| Calculate base consumption | 24 drinkers × 1.5 drinks/hour × 3 hours | 108 base drinks |
| Apply consumption decay | Adjusted for drinking slowdown over time (decay factor: 2.65) | 95 adjusted drinks |
| Apply wedding shower modifier | × 1.4 (+40% for wine) | 134 wine servings if served alone |
| Share of the bar | 134 servings × 33.9% | 45 wine servings |
| Convert to bottles | 45 servings ÷ 5 servings per bottle | 9 bottles (raw) |
| Add 15% buffer & round up | 9 × 1.15 = 10.3, rounded up | 11 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 shower
How much wine do I need for 30 guests?
You need 11 bottles of wine for 30 guests at a wedding shower, assuming you are serving a full bar. That is 45 servings with a 15% buffer. If wine is the only alcohol you serve, plan on 31 bottles instead.
How much wine per person for a wedding shower?
Plan for 1.5 servings of wine per person at a wedding shower 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 33.9 percent of what gets poured.
How many servings are in a bottle of wine?
One bottle of wine contains 5 servings. For 30 guests, you'll need 11 bottles to provide 45 total servings.
What percentage of the bar is wine at a wedding shower?
About 33.9 percent of the drinks poured at a wedding shower are wine. With 30 guests, roughly 24 will be drinking, and that share works out to 11 bottles.
Should I buy extra wine as a buffer?
Our figure of 11 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 11 bottles of wine last for 30 guests?
11 bottles of wine will last approximately 3 hours for 30 guests at a wedding shower, alongside the other drinks on the bar. This factors in the natural slowdown of consumption as the event progresses.
