I’m thinking of getting a big champagne or Prosecco for my parents golden wedding party but I don’t know how big you have to go for it to be impressive - it’s hard to tell scale online. Is jeroboam (4 bottles worth) enough? I want it more for the grandeur than to actually have to make sure it serves everyone as there will be plenty of other booze.
Also how do you know if it’s going to taste ok and where to shop that isn’t too pricey?
