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.
3 is what I'd do if I were looking for a light roast, though it's only just barely fitting my definition of that, roasted to a point just a tiny bit before the start of 2nd crack. Sweet, has a very subtle lemon flavor that a lot of people would fail to notice. I'm not going to do a production test batch of this one because I don't have the shelf space to add it and if I did try selling all four, this is the one that my customers would buy the least.
6 is firmly in line with what I've done with this lot in the past for a medium roast. It was a toss up between this and 5 for that, and 6 was just generally a nicer roast. Better body and balance, more interesting flavor. Coffees in this range had a very nice caramel fragrance straight out of the roaster.
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.
From lightest to darkest, those would be cups 3, 6, 9, and 12.
