In the mid-90s, travelling between BUD and LHR on a 757 (my favourite short-haul plane) when there was a full catering service in Y, for several years they served an absolutely delicious NZ sauvignon blanc (in the big little bottles, 25cl, rather than the little little bottles, 18.75cl). Can’t recall the name for the life of me, but I do remember there was never a problem in getting 3 or 4 of them for the two-and-a-half to three-hour journey.
