That said, as your palate evolves, it will place an ever-greater premium on the consistency and quality of the grinder. Provided your taste buds are sensitive enough, the quality of grind will make ALL the difference, and it's often said that the best investment in coffee gear is always a great grinder.
There are two main families of grinder: blade and burr. Blade grinders, very much like a blender, slice up the beans. They're considered entry-level, but can be an inexpensive path if you're new to coffee. Burr grinders, on the other hand, pulverize beans, and because of that action, produce not only more consistent grounds, but also do a great job of increasing surface area, which leads to richer extraction.
Common "best in class" grinders used in commercial settings include Mahlkonig
. In the home, there's a bewildering array of grinders. I'm personally a fan of the Breville Smart Grinder
and any of the models from Baratza
(a local brand). The Encore
is a great option that's super high quality without breaking the bank.
