I have 26 attendees who I am accommodating for a champagne toast , to give them all the option, so one glass each.
6 of these attendees are low alcohol or alcohol free because of various things (but may well say yes to the champagne as a one off). For the remaining 20 , how much wine(red and white) should I provide for an evening meal? They have the ability to grab cocktails, beers etc too but I need to make a decision on the wine.
