Hiya David,
If re-packaging 750ml bottles into tiny bottles is not your bag :-),
another route you may want to explore are the "Boxed" wines. You might
try Australia's Hardy's Chardonnay or Shiraz,as both are fruity,off-dry
styles and the cool "bladder" that they are in is air-tight and can
last in the 'frig for weeks. This type of packaging is very popular in
Australia, known as "casks", and quite useful when you're on a budget
or a sporadic consumer. Furthermore, Producers of Premium quality
wines ($8-$12 range) are experimenting with this type of packaging so
ask your favorite Wine shop to point you in their direction. Glad that
you are drinking wine!! Keep it up! Slainte
