How Much Wine Do I Need for a Party?
Calculate total wine servings first. Only then split the bottles between red, white, rosé or sparkling wine according to the people and food at your event.
A transparent method
Estimate the number of wine drinkers, choose an average glasses-per-hour assumption, multiply by serving time, then convert the resulting millilitres into bottles using your intended pour size.
Why pour size matters
A bottle does not contain a fixed number of glasses unless the pour is fixed too. Smaller pours produce more servings; larger pours produce fewer. Enter both values rather than relying on a universal “glasses per bottle” claim.
Do not let a default wine split create waste
A summer garden party, dinner and birthday can have very different preferences. Calculate the total requirement, then choose the mix based on what guests are likely to drink.
Example
Twenty wine drinkers × four hours × 0.8 glasses/hour = 64 glasses. Add 10% and use 125ml pours from 750ml bottles: the estimate rounds up to 12 bottles.
