I guess i just enjoy the finer things in life pun intended
I think it’s really just about knowing your setup and creating the balance for the extraction you prefer. In the Ikawa SCA video I posted someone said that you roast for your grinder and the majority of my thought is that is simply untrue and IMPO a cope out, they were just not able to balance the brewing method (espresso) in order to extract for that flavor. This can be tested by smelling the fresh ground coffee, no matter the grind size. Whether French Press, Aero, V60 or turkish, if I smell berry in one I smell it in all. Now roasting for the water has IMPO scientific merit where the level of calcium and other things will affect the solubility and thus the chemicals extracted from the grounds and the water definitely can mute or express flavor.
