Aside from the alcohol content of various beverages, it is worth taking note of the portion size. 5 ounces of wine is not a whole lot–I measured it in the wine glasses I use at home and it’s not what you’d call a generous pour in a bar or restaurant.
I am not much of a drinker myself, although I have recently started to drink a glass of wine (a small glass–around 4 ounces!) at home some evenings. And I don’t go out much where people drink–maybe once or twice a month. Two drinks is really my limit. When I was young and foolish, that was called a cheap date!
