You mean the taste is not good? I have only roasted one batch of this quite similar to what you did FC around 11 mins and SC about 16. I let it go into RSC, about 30 sec after first snaps of SC. My roast was also CS10, very even. I only left it for 5 days before drinking and I quite liked it. I tried it as a single origin but I thought it was better in a blend. Ill be roasting some more of this today so I can blend it with some Ethiopian Harrar, Indian Madikery and PNG Wahagi that I roasted yesterday. All the best!
