Had a pourover of the Kenya Kieni at lunchtime, not quite 48hrs post-roast. Gotta say I'm really liking what I tasted in the cup, of course this is not a fair comparison against pre-mod Kieni as I didn't have a side by side pre and post-mod cup at lunchtime. But, based on what I tasted it seems like the cup had more 'transparency', 'clarity' and better stage presence vs. pre-mod.
It's going to take quite a few roasts to nail it down for a definitive opinion but so far so good.
All hail GC7!
