I'm kinda amused at how much "casual drinker" definitions vary, as well as alcohol tolerances. like for people it takes couple of bottles to get to tipsy stage, while for me it takes couple of ounces :P usually when I do drink, I'm either splitting a bottle of cider or something (one of those personal bottles) with hubs, or have like half a glass of wine. we haven't been buying much wine lately though, as its hard to find in smaller bottles and regular size bottle will end up sitting in a fridge too long, to the point where it doesn't even taste good anymore.
P.S. cheap wine is... not the taste I have ever learned to aquire >_>
