Wine for a birthday: how much to provide and how to choose
For a birthday party, count on 2 glasses per person for the aperitif and 2 to 3 glasses for the meal. For 20 guests with a cocktail hour and dinner, plan for about 15 liters — or 3 x 5L BIBs. For a dance party without a sit-down meal, consumption is lighter: 1.5 to 2 glasses per person per hour.
Aperitif, dinner, or party: it's not the same calculation
A birthday can take a thousand forms. The calculation is not the same depending on whether you are hosting a cocktail dinner, a sit-down meal, or a stand-up party.
Cocktail dinner (2-3 hours): 3 to 4 glasses per person. Guests graze, move around, and conversation flows. Consumption is steady but not excessive if food is provided.
Sit-down meal (starter + main + cheese): 3 glasses per person for the meal + 2 glasses for the aperitif = 5 glasses per adult in total.
Dance party (no meal): 2 to 3 glasses per person over the course of the evening. Dancing and the atmosphere often balance out the consumption.
Quantities by number of guests
10 people, cocktail + dinner: about 7 to 8 liters → 2 x 3L BIBs + 1 x 3L BIB in reserve, or 1 x 5L BIB + 1 x 3L BIB.
20 people, cocktail + dinner: about 14 to 16 liters → 3 x 5L BIBs.
30 people, cocktail + dinner: about 20 to 24 liters → 3 x 10L BIBs or 5 x 5L BIBs.
50 people, party: about 25 to 35 liters → 3 x 10L BIBs.
Which wines should you choose for a birthday?
The golden rule for birthdays is that there should be something for everyone. Avoid overly technical or distinct wines that divide opinions — opt for expressive, accessible vintages that even non-experts will enjoy.
For the aperitif, a fruity white or a Provence rosé rarely disappoints. Natural sparkling wines create a festive mood without the next-day headache. For the meal, a light and fruity Gamay from Beaujolais is a crowd-pleaser that pairs with almost any dish.
BIB or bottles for a birthday?
For a birthday of 20 people or more, a BIB (Bag-in-Box) drastically simplifies logistics. No last-minute uncorking, no half-empty bottles to manage, no empty crates to stack. You plug it in, you pour it, that's it. And leftovers keep for the next occasion.

Frequently asked questions
How many bottles for a 30-person birthday?
For 30 adults (cocktail + dinner), count on about 20 to 25 liters, or 27 to 33 standard bottles. In BIBs, that’s 3 x 10L BIBs or 5 x 5L BIBs — much easier to manage.
Can you mix BIBs and bottles for a birthday?
Yes, it's actually a good strategy. BIBs for the staple wines (red and white that will be poured throughout the meal), and bottles for exceptional wines or curiosities you want to introduce.
