How to plan for a party when serving boxed wine

If you're planning to serve boxed wine at your event, take into account the number of guests you anticipate will be drinking. Once you have an estimate of how many attendees will partake, make an informed guess about how many glasses they might consume. For instance, if you expect 10 guests to each enjoy two glasses of wine, a single 3-liter box (which holds 20 glasses) might suffice. Alternatively, you could opt for two 3-liter boxes (40 glasses) or one 5-liter box (34 glasses) to ensure you have enough.
Additionally, consider that you may want to serve larger pours than the standard 5 ounces. If you prefer a more generous serving, be aware that the box may deplete more quickly than you expect. For example, if each guest pours themselves 7 ounces, that would yield only about 14 glasses.
If you're uncertain about how much boxed wine to purchase for your gathering, it’s wise to err on the side of caution and buy an extra box just in case. One advantage of boxed wine is its longevity after opening; you can store an open box in the fridge for up to six weeks, allowing you to enjoy any leftovers well after the event.
