Wine Calculator — Bottles Per Guest

A standard 75cl bottle pours 5-6 glasses at 125ml (6 exactly, but with slight spillage 5 is safer to budget for), about 4 glasses at 175ml, or 3 glasses at 250ml. Most UK restaurants serve 175ml as a standard glass, but 125ml is the standard measure for party planning.

Plan for about half a bottle per wine-drinking guest for a 3-4 hour party, or a full bottle for longer events. Not all guests will drink wine — typically 40-60% choose wine over beer or spirits.

A 50/50 split works well for most events. In summer, shift to 40% red and 60% white/rosé. In winter, go 60% red and 40% white. If you know your guests well, adjust to their preferences.

Rosé is increasingly popular in the UK, especially for summer events. Plan for about 20% of your wine to be rosé at warm-weather parties, less in winter.
