You'll see that consumption ebb and flow as years go by. When we got married in 1983, we barely needed a quart a week. For the most part, it was only for coffee. We tossed more out than we ever finished.
When the kids were born in 1985 and 1988, and began drinking milk instead of formula, I went through a couple of gallons of 2% per week. It more or less stayed in the one gallon a week camp for about 10 years, until they hit the teens and the idea of eating breakfast went out the window. Then I was down to half a gallon a week. I stayed there for 6 or 7 years. At some point I switched to 1%.
Now that both are home for the summer, and both eat cereal around noon (if they have no classes or work), I'm back up to a gallon a week. Funny, they use it in their coffee, now, too. I've switched to light cream for my coffee.
I suspect that when Coco goes back to school in the fall and Mark gets his first 'wear a suit to work' job, I'll probably be back at a quart a week. More money to spend on wine, I say.
