For the first time since the Roman empire, wine could now be stored and aged in bottles. Throughout the Middle Ages wine had been kept in casks which had presented a dual handicap: first, too long kept in wood could rob a wine of all its fruit; second, once the cask was opened the wine inevitably deteriorated unless drunk within a few days.
