Coffee is an absolute essential in my house. Growing up, every day after school, my Grandmother would give me what she called "Little boy coffee", which was an ounce or so of coffee in a cup of milk. This started when I was about 6 or 7 years old, she said it was the way she grew up, sort of a "German" thing.
Anyway, for many years my wife and I used a Mr. Coffee brewer and Dunkin' Doughnuts coffee. A couple of years ago we started using a Keurig brewer, mainly because I broke the carafe on the Mr. Coffee, and I had the Keurig sitting there as a backup. My wife still uses Dunkin' Doughnuts French Vanilla pods, while I like the Newman's Own, Organics Special Blend.
I normally drink 1 cup before I leave for work, 1 cup for the road, and 1 or 2 more at work, (there's a Keurig in the office). Then 1 or 2 cups at home, after work. This may seem like a lot, but it's actually a drastic reduction from times gone bye. In the mid 90s, when I worked in a Special Housing Unit, the Sergeant and I would go through 4 pots over the course of a shift, just to have enough energy to keep up with the work load. Interestingly enough, my two adult sons hardly drink coffee at all.
Just as an aside, I was in Victoria B.C. last week, and had the opportunity to stop at a Tim Horton's coffee shop. Very tasty coffee, and nice muffins too!
