Test batch on the new coffee from Guatemala had some really nice flavors at some points, some really boring flavors on others. Nothing offensive, but four of the twelve cups were distinct expressions of that coffee which I could potentially sell if I had the shelf space for that. The next step is production test batches which I'll taste (this time out of 3L airpots instead of cupping bowls) before deciding if those are what I want to sell.
9 is representative of what I'm looking for in a dark roast for this coffee, while 12 is just perfect for something that you'd sell not as Guatemala Antigua but as French Roast, and since my Brazilian coffee isn't here yet I think I'll try that.
