What makes certain coffee the way it does? As far as I'm concerned it's from the actual coffee tree (specie, varietal, etc) and it's environment. And then when you roast the coffee, you can sort of control, with temperature, what 'stands out'?

Your right, except for the roasting bit, there's under-roasting, correct roasting, over roasting, destroying. The range of correct roasting is small for most coffees and as you reach the end of that range the roast takes over and varietal specific flavours are subsumed into the roast taste. Under-roasting simply doesn't begin to bring out the flavours.

Yes and let it go a little too long and you have charcoal.
roasting can't bring out flavors that are not there. It is the bean, the soil, shade or sun, mountain or valley, elevation all this and more is what gives coffee its flavor.

roasting until all you taste is charcoal and ash can also provide some real consistency for commerical chain establishments, so they all produce the same swill time after time...even if you try to cover it all up with milk and syrup

You are correct in that the roast can have a lot of effect on the taste. However, the environment...ie climate, soil, amount of shade (or no shade), elevation, and temperature all can have an effect on the notes and flavor. In fact there are some Micro-Lot farms in Costa Rica and Panama that produce only Arabica coffee, but depending on the plants location on the farm, the coffee presents different flavor notes. Some are considered exceptional and score very high when cupping and others from the same lot don't score as well. A lot of the smaller Organic operations have the ability track and evaluate the quality of different lots based on the location of their farms....very interesting!
