Champagne - Veuve Clicquot
1 Bottle should be sufficient for 5 People
The first question people tend to ask is, how much Champagne should I get? 150ml is the standard amount that fills a Champagne flute. So that is just about 5 glasses of Champagne in a given bottle. Remember, that is just enough for a toast itself. If you want people to be able to ask for a second glass, make sure you plan appropriately and get a few more bottles than that. Also, you have to assume some people will spill their glasses by accident and need more before the toast happens. You don't want to have to tell them "sorry you had your chance, now you can't toast".
