How to Calculate Wine for an Event

Formula

Total Glasses = Guests x Hours x Glasses per Hour

Glasses per Bottle = floor(25.4 oz / Serving Size)

Bottles = ceil(Total Glasses / Glasses per Bottle)

A standard wine bottle is 750 mL (25.4 oz). At a 5 oz pour, that yields 5 glasses per bottle.

Planning Tips

  • Budget 1 glass per guest per hour as a starting point
  • Reduce to 0.5-0.75 for afternoon events or events with other drink options
  • Increase to 1.25-1.5 for cocktail parties or wine-focused events
  • Buy extra and return unopened bottles if the retailer allows

    • Example Calculation

    20 guests at a 3-hour dinner party, 1 glass per hour, 5 oz servings.

    1. 01Total glasses = 20 x 3 x 1 = 60 glasses
    2. 02Glasses per bottle = floor(25.4 / 5) = 5 glasses
    3. 03Bottles needed = ceil(60 / 5) = 12 bottles
    4. 04That is 1 case of wine.
