LOL... Indeed. And it proved darned stubborn this morning. I lay my blind exploration bare for all to see...
Day 1 Notes:
- Start off at 9 on grinder and level dose, temp at 200 even.
- Crema of first shot is right there, banana cream pie hints and very good just as per the description but then off to something burnt woody and bitter/uninteresting after the first sips of crema. Perhaps doesn't like to be overextracted? Pulls tons of crema, overflowing the cup compared to previous coffee (Sidamo Dare from Verve), but much too fast. (Oh, and these beans are 5 days out of roast, so shouldn't be an overly fresh issue on the crema volume.)
- Second shot, tighten grind substantially and pull shorter, to 1.8 oz, still fast, but shot is better, sweeter for longer after crema dissipation but not all the way, going to keep going in this direction.
- Third shot, now overdosing substantially rather than just barely over level, and now pulled to 1.5 oz in 20 secs (still fast but better...), now getting more sweetness and fruity tastes after crema is dissipating (or sipped off) but with a bit of loss of the banana and creaminess I had at the beginning and also still mixed with a burnt woody taste I just don't like. Don't know whether to try upping the temp to bring out sweetness or drop it to get rid of burnt taste, guess I'll try both ways...
- Toss most of shot 1 in the sink, remainders of shots 2 and 3 into a sugar and creamy americano for Heidi and this has kicked me in the side of the head, might be a bit of caffeine in this bean, will wait a bit before brewing any more.
Very interesting initial revelation on this one, esp. in the first two, faster pulls, the crema of the shot tasted sweeter and creamy and interesting and then it faded rapidly off into the distance such that 15 seconds after the pull, it tasted completely different (and not as good by far).
Two hours later:
- Shot #4 - Tightened up the grind a bit more and upped temp by half a degree to 200.5, shot pulled a bit short now, but darn it, definitively burnt and bitter tasting. Perhaps too hot...?
- Shots #5 and #6: Lower temp by a degree to 199.5 or so and dropped dose to compensate for slightly too fine a grind, better/not so burnt taste, but still not ideal, I actually think shot #2 might have been the best. Perhaps this one will be better with a faster pull, or just a coarser grind and I can overstuff the basket to compensate...? Will loosen the grind and leave lower temp and return to this tomorrow.
