Each 22-oz bottle of Bacardi will make 11 Mojitos at 2 ounces of rum per drink. Assume only a third of those attending will be having Mojitos, so that’s maybe 50 drinks total. Five bottles will do.

You’ll also need 25 fresh limes, a bottle of simple syrup, 50 sprigs of fresh mint, a couple bottles of mineral water to top, and don’t forget the ice and a muddler.

PupnTaco, nice answer! If it’s going to be hot, though, you might up the supplies. Mojitos are sure to be popular!

I would say about 6 Bottles just to be one the safe side. You never know….But Pupn…Has a great answer.

15 bottles worth and what you have left over take it with you on thx honeymoon.

I guess all depends on how hammered everyone will get.

With the same glassware, you could also offer a Tom Collins. Great hot-weather drink. You’d need the same amounts of gin, lemons, simple syrup, and mineral water, plus maraschino cherries for a garnish… and a lime wedge if you’re West Coast, orange wheel otherwise.

RecipeZaar has a great mojito recipe at http://www.recipezaar.com/66947. I made these for a party a few weeks ago and I’m not sure we got 10 drinks out of each pitcher, maybe more like 6 or 8 (we were using 8-oz plastic glasses). If you add more club soda, the rum will stretch farther. I would say buy more rum than you think you’ll need—most liquor stores will let you return any unopened bottles. Fresh limes are really the key but if you don’t have a juicer, be prepared to use some elbow grease!

Thanks a lot – this is a huge help!
