How to Plan It
Notes for
the host.
Note per l’Ospite
Bella Principessa Social Club
Just a toast
One glass each, poured a little short. A bottle covers six guests.
Brunch, reception or party
Most guests drink two or three glasses. Use three if the evening runs long.
Mimosas and spritzes
Juice and Aperol stretch each bottle, so you can scale back by about a third.
Count drinkers, not invitations
Leave out the designated drivers and anyone under 21, and have good alcohol‑free options on hand.
Chill more than you need
Serve at 43 to 46°F. Running out of bubbly is the one party detail everyone remembers.
Salute.

The Gold and the Rosé, both Brut, in ceramic‑painted bottles that look like a gift before anyone wraps them.
Please enjoy responsibly. Guests must be 21 or over, and everyone needs a safe way home.

The Bottle
Dressed for the table
before anyone pours.
Every Bella Principessa bottle is ceramic‑painted, with no paper label, so it looks like part of the party from the moment it’s in the ice. Gold and Rosé, both Prosecco DOC Brut.
Before the party.
How many bottles of Prosecco per guest?
Plan on five 5‑ounce glasses a bottle. Two or three glasses a guest covers most parties, so a bottle serves about two guests; for a single toast, one bottle covers six.
The formula for bottles, guests and poursHow much is in a standard bottle of Prosecco?
A standard bottle holds 750 mL, about 25.4 U.S. fluid ounces: five 5‑ounce glasses, or six 4‑ounce toast pours.
Glasses per bottle, in mL and fluid ouncesWhat is the ideal serving temperature for Prosecco?
Around 6–8°C (43–46°F). Keep the bottles cold between pours.
6 to 8°C, rosé, and keeping the second pour coldHow long does Prosecco last once opened?
Keep an opened bottle cold with a proper sparkling‑wine stopper and finish it soon; the bubbles fade a little every hour.
