I posted a question about coffee growing, and asked what mechanisms affect the flavor of coffee grown at different altitudes (I was thinking of things like temperature, wind, soil differences, etc. might come up).
At least one person suggested that this second part of the question (about what mechanisms cause flavor differences if altitude does indeed affect the final product) was "too scientific" and suggested that it be closed.
Does this mean all growing questions should be off topic? Or all questions related to the chemistry or biology of coffee? Where do we draw the line?
