Working out of the house, I just brew a carafe first thing, then have it over the course of the morning.
I like cinnamon which I add to the coffee grounds, so that during the steeping process the beneficial compounds get released into the coffee.
I also add a pinch of salt to knock off some of the bitterness of the dark roast.
K-cups are ridiculously expensive, unless someone else is supplying them for you.
I just hate the waste in the form of the plastic because you just know the majority of them are not being recycled.
