I roasted up my 1/2lb of the auction lot last Friday. I reduced wattage from 1150W to 1000W once I got to 1st crack so I could extend the time a bit without roasting it too dark (GeneCafe is 1300W without VariAC on my 20A circuit). Ultimately, I ended up with what I would call a city roast. Had I cut the roast 15 seconds earlier, there probably would have been some green taste left to it.
Saturday I brewed two pots (I busted the vac pot preparing to brew this coffee, so I had to use the Technivorm). In both instances, the results were very good, but that's about it. Somewhat bitter too.
I brewed a pot on Sunday morning and it was exceptional. It was very fruity, but in a soft, citrusy way. This was in complete contrast to the fruitiness of Ethiopia Aricha Selection 7. It almost smelled like a bowl of canned fruit cocktail. This was also a very sweet tasting coffee... sweeter than anything I've had before. The only bad thing was that it was still a bit bitter.
For my second pot Sunday, I stepped the grinder up 1 size to eliminate the bitterness. Sadly, the over the top fruitiness was largely absent. It is possible that my nose just adjusted to some extent though.
Monday, I brewed the last pot back on the smaller grind, and it was bitter again. The fruitiness was there, but it was eclipsed by the bitterness.
I've never had a coffee turn out bitter in the Technivorm before, but this was a roasted lighter than I usually roast, and the acid profile was completely unique.
I think the coffee has incredible potential, but I found it difficult to work with. Perhaps another 30 seconds in the roaster would have made a big difference. I might buy some of the non-auction just to satisfy my curiosity.
