My first choice would be black coffee. 5 to 10 cups a day. But I've cut way back.
In the category of alcohol, my favorite would be Kahula, added to coffee. While I enjoy it, I may drink this combination less than 1 cup per month.
By volume, the most alcohol I drink is wine. A glass with dinner 3 or 4 nights a week is common.
But after physical labor, yard work, etc, a good cold beer hits the spot. I tend to drink beer more in the warmer times of the year, or at social gatherings any time of the year.
