Drink planning depends on guest count, event length, season and audience style. A formal dinner with strong wine preference behaves differently from a warm-weather party with cocktails and beer.
Start with total drinks per guest and then split by beverage profile. That gives you a cleaner estimate than buying random numbers of bottles with no category logic.
It is smarter to buy with a buffer than to guess aggressively low. But that buffer should be measured, not emotional. A clean drinks list makes service and hosting feel more polished.

Common questions
How much buffer should I add?
A modest margin helps, especially with warm weather or longer receptions.
Should I plan by bottles or servings?
Start with servings. Convert to bottles only after you know the mix.
