Wedding Drink Calculator
Champagne for the toast, wine for dinner, cocktails for the dance floor, all calculated for your exact guest list.
Wedding
A wedding bar is three bars in one day
A welcome reception (sparkling and light drinks), a seated dinner (wine on the tables, one runner per 20 guests keeping glasses full), and a party (cocktails, spirits and beer until late). Consumption is higher than a normal party in the first hours and stretches across many more.
PourBrief models this with wedding-specific consumption modifiers, adds dinner-service staffing on top of the bar team, and lets you split wine into red, white, rosé and sparkling, so the champagne toast is never the thing you forgot. For 100 guests over 5–6 hours, a professional bar plans roughly 1,600–2,000 serves; the calculator turns that into bottles, cases, kilos of ice and a single consolidated shopping list you can hand to your caterer or take to the store.
Frequently asked questions
How much alcohol do I need for a wedding of 100 guests?
Over 5–6 hours a professional bar plans roughly 1,600–2,000 serves, which is higher than a normal party because the day starts with a reception and runs long. PourBrief splits that total across sparkling, wine, beer, spirits and cocktails and gives you the exact bottles.
How much wine do I need for a wedding dinner?
A 750 ml bottle pours 6 glasses of 125 ml. With a seated dinner, plan 1 glass of white and 1 of rosé per guest plus 1 bottle of red per 25 guests: about 38 bottles for 100 wedding guests.
How much champagne do I need for the toast?
One glass per guest, and a 750 ml bottle pours about 6: around 17 bottles for 100 guests. If you serve sparkling by the glass through the reception instead of a single toast, plan half that per guest and let the bar pour on demand.
Do I need extra staff for a seated dinner?
Yes, on top of the bar team. A seated service needs runners keeping glasses full: roughly one per 25 guests on a mid-size dinner, relaxing to about one per 60 at large events. The calculator adds them automatically when you mark a seated dinner.
