Formula and method
Twenty wine drinkers give ten bottles split five red and five white. Twelve beer drinkers over three hours give 36 modeled beer units.
Wine = 2 × ceil(ceil(drinkers/2.15)/2); beer units = ceil(drinkers × hours)

Assumptions and limitations
- These are fixed shopping allowances, not recommended consumption or alcohol safety limits. Wine is split equally into rounded red and white bottle counts; the wine and vodka estimates do not scale with event duration. Offer nonalcoholic choices and adjust stock to your event.
- Beer stock is modeled in 500 mL units before changing the container selector. Some customary-volume options retain rounded captured conversion factors; whole-container shopping may need rounding upward.
