Ever since reading this article from Prima Coffee comparing Kalita Wave recipes, I've been using the George Howell method. This recipe calls for 25-28g of coffee for 390g of water.
I find this to be fairly strong and I wonder why the recipe calls for this large amount of coffee. In the past I had done ~18g of coffee for my pour overs and thought it brewed a decent cup. I understand I'm free to change the amount per my own tastes/roast, but I want to know if there's specific reason why 25/390g seems to be the chosen ratio.
Thanks
