A reliable rule of thumb for a party is to plan on about one drink per guest per hour, then adjust for the crowd and occasion. For a typical evening event that often works out to roughly two to three drinks per person for the first couple of hours, tapering after. A standard 750ml wine bottle pours about five to six glasses, and a case of beer covers a small group — so estimate total drinks first, then convert into bottles and cases.
Start with time and headcount. One drink per guest per hour is the standard planning figure, so 20 guests over four hours suggests around 80 drinks before adjusting. People drink more in the first hour or two and less later, and daytime events tend to be lighter than evening ones, so treat the number as a base to flex rather than a fixed order.
Turn drinks into stock with a few conversions. A 750ml bottle of wine pours roughly five to six glasses; a bottle of spirits gives around sixteen standard measures; beer is easiest counted by the can or bottle, with cases making larger orders simple. Split the total across wine, beer and spirits according to your guests’ likely preferences rather than assuming an even divide.
Build in a margin. Running out mid-event is the one outcome worth avoiding, and unopened bottles keep for next time, so rounding up is sensible. Offer some non-alcoholic options too, and remember that in the UAE guests should be 21 or over and the event should be in a private or licensed setting. For larger gatherings, CityDrinks’ case deals and bulk options make it easy to order the volume in one go across Dubai and Abu Dhabi.
