Planning notes for a graduation party

Set up a visible '21+ only' bar area and a killer mocktail station so younger guests feel included.
Parents of graduates usually drink less than the graduate's friends, so plan your ratios accordingly.
Keep champagne cold but corked until group photo time - pop bottles for the shot!

Graduation parties typically skew toward beer and lighter drinks. Stock up on popular light beers and have a good selection of non-alcoholic options since many guests will be under 21. Sparkling cider is a great champagne alternative for toasts that includes everyone.
