How far in advance can you make a mixed drink?

Pre-mixing cocktails is a great idea for serving a large party, or even just to help you save time throughout the week. How far in advance you can make a mixed drink depends on the drink’s individual ingredients. Something spirit-forward, like a martini cocktail, will last longer than something with perishable ingredients, like a fruity drink. Figure out the amount of time all ingredients will last and then consider the shortest one your answer.
