Yes, absolutely. The other thing to note is that you cannot roast two different beans “the same way”. They do not roast the same. You could roast two to the same degree (same final temperature, or final color), but the way that two wildly different beans absorb heat is going to be radically different. Density of the bean and the internal moisture play a huge role in this. Denser, more moist beans will roast slower and require more heat. Likewise, less dense beans will roast more quickly and may be subject to defects relating to essentially scorching if the same amount of heat is applied. I roast coffee at a… semi professional level, and I would say that roasting can only make a coffee worse, it cannot be additive. You only bring out the flavors of the origin beans, and if you do it wrong they will taste bad. You can’t make certain coffee taste like fruit, for instance. It just doesn’t exist in the origin coffee. I am currently drinking three different coffees, and they have three wildly different flavors. One has a very low body, tea like, and earthy flavors. One has a chocolatey cocoa flavor, and one tastes like syrupy rich body with ripe cherry. It’s absolutely unmistakable.
