I have people ask me all the time about how to estimate drink quantities. My first response is usually 2 drinks per person, per hour, which might seem high for most people. But lets face it, I could drink 2 glasses of wine in 1 hour. I’d always rather have more than less. I just found a cool document for those of you trying to plan out beverage quantities for a party. Thanks BEVMO!!
(also, both Bevmo and Costco will buy back your unopened bottles as long as they are able to resell it. so you should always buy more and then you can return any extra)
