I understand. I don’t get exactly the same degree of roasting each time. The roasted beans themselves are not as consistently roasted as ideal, either; after I grind them, I notice some lighter and darker grounds mixed in. But that doesn’t seem to affect the taste, as least as far as I can tell.

Anyway, it’s for my consumption only. I’m enjoying the manual roasting process, and I think I am gradually getting better at it.
