We’ve all been at a beach club in Ibiza or Mykonos when a neighbouring table orders a supersized bottle of booze, complete with sparklers and a sense of occasion that makes yours pale into insignificance. Shameless showboatery? Probably. But there's a method to the madness as well.
Magnums – that is, bottles double the size of the standard – don’t just bring the party; they offer a raft of surprising benefits for the wine itself, while being more economical (yes, really).
