Really depends on my mood and the food being served. Low brow home cooked meal about $16-20. When were serving something special, I'd say more in the $26-34 range.
I have just a few $10 bottles at home. Usually keep a few around to bring to friends houses that think "two buck chuck [$2.49 now]" is adequate.
Took inventory a few weeks back, and realized based upon our normal consumption rate, we probably have a three year supply of wines in this price range stored.
