This is a great coffee.  Its dark but not bitter, a little chocolaty, and it reminds me of an Adirondack lodge.  I can get them for a better price in a Caribou Coffee store, however.

This is one of my favorite water add-ins. I think it has a really crisp, clean taste...with a hint of grassy-ness. The tea particles tend to settle at the bottom of the bottle, if left standing for more than a few minutes, so I have to shake it up periodically. There are times when I feel like I'm drinking something that was squeezed off the blades of a lawnmower, but this seems to be based on my choice of sweetener. It tastes great when I use stevia, but when I use Sweet & Low...I get a bitter-ish grassy taste.
