on average my wife and I will have 2 bottles a day. some days 2-1/2 some days not much. depends on how we are feeling. we belong to several winery wine clubs so we can drink at discount and of course collect bottles for our new winemaking hobbie.
Oh and add in a small cordial of Port before bed to top off the evening.
We really aren't lushes, even if it sounds like it compared to Joan.
