How to Calculate Drinks Per Guest

Formula

Total Drinks = Guests x Hours x Drinks Per Hour

Planning Guidelines

  • First hour: 2 drinks per guest
  • Each subsequent hour: 1 drink per guest
  • Average over a 4-hour event: 1.5 drinks/hour
  • Assume 30% of guests will want non-alcoholic options
  • One bottle of wine = 5 glasses
  • One keg = about 165 glasses of beer

    • Example Calculation

    Calculate drinks for 30 guests at a 4-hour party.

    1. 01Total drinks: 30 x 4 x 1.5 = 180 drinks.
    2. 02Wine bottles: 180 / 5 = 36 bottles.
    3. 03Beer cases: 180 / 24 = 7.5 cases.
    4. 04Plan a mix: perhaps 15 bottles of wine, 3 cases of beer, plus soft drinks.
