My single member club has a continuous stock of 4 or 5 bottles. As one bottle is emptied then another is bought to replace it, from a flavour point of view there's little worse in the spirits world as 1cm of good drink oxidising into dregs* ** *** . Loads of near empty bottles looks more depressing than impressive to me .
*Except 12yr old Glenfiddich of course.
** Not woowoo , it's knowledge gained from comparing dregs to a freshly opened bottle.
*** You can use miniature bottles to keep the last bits of a bottle relatively fresh for comparison
