Well, what you say about quality being expensive is totally true, since doing something worthwhile will be something expensive.
By the way, what you say that depending on the place where the coffee is grown will influence a lot in its flavor, you are right, for example where I live coffee is grown in different parts, in some temperate areas and in other warm, and the flavor is very different, also influences the way it is roasted, for example roasted with the sun like cocoa is very different from roasted with fire.
That's interesting. I don't know much about the different roasting processes. I assumed they were all done in large oven like machines. Sun roasted sounds very interesting though. I don't think I've ever tried sun roasted coffee but I would like to 😁
