Hi everyone! I’m getting married soon and I’m looking for advice on which champagne(s) to buy for my guests.
We will be serving champagne during the cocktail/reception (with savory appetizers, and there will also be mojito cocktails). Then champagne again will be served with dessert (tiramisu and cream puffs).
We’re looking for something around €20 a bottle. Something easy to drink, not bitter. (I’m also open to buying two different champagnes.)
A colleague suggested the “Duménil Brut Premier Cru” champagne, apparently 1/3 Chardonnay, 1/3 Pinot Noir, 1/3 Pinot Meunier. What do you think? Do you have any other champagnes in mind to recommend?
P.S. I live in France, but I don’t know anything about alcohol!
Thank you!
