For those of you who are concerned about the use of chemicals in the decaf process, Mountain Water Process Guatemala is worth your consideration. I’ve discovered that Mountain Water Process (the Mexican plant) is often less bitter and more flavorful than Swiss Water Process (the Canadian plant). This is also one of the few Decafs that is available with Fair Trade and Organic certification (so that's the one we buy every year).
Although I appreciate that you can roast this one on the light side of medium, I've been roasting it on the dark side of medium, just barely into the second cracks. If you go darker than that, you start picking up more bitterness, although with a splash of cream that bitter-baker's chocolate taste can work well. It also lends itself very well to blending. It can make a really nice half-caf blend when you pair it with a sweet light roast.
