Thank you for your email.
Yes, indeed there is a powder on them, that is cinnamon.
We have Guji Grade 1 and Guji Grade 1 with a hint of cinnamon, and by looking at your most recent order I can see the second one was selected on this occasion.
This is very popular among customers, so we would recommend giving it a try as it makes for a lovely cup :).
So they decided to send me a cinnamon coated beans even though this wasn’t my order! Funnily enough how did I not pick up on it?! They had a real spicy aroma but that’s what roasters description was so thought it’s a good match…
Also wondering about the grinder as cinnamon fines will be stuck all over it so most likely clean required.
I enjoyed coffee and service from them previously but having doubts on placing more orders now.
