For a ground coffee we would like you to specify the grind you need for a particular coffee machine. For example:

Drip Grind:
Very distinct particles of coffee. Like heavy-grained kosher salt. Downright chunky. (Used in Drip Machines)

Fine Grind:
Smoother to the touch, a little finer than granular sugar or table salt. (Used in Espresso makers)

Espresso Grind:
Finer than sugar, but not quite powdered. Grains should still be discernable to the touch. (Used in most Espresso Machine for home and commercial use)

Turkish Grind:
Powdered, like flour. Most inexpensive (blade) grinders will be unable to grind this finely. (Used with Ibrik Machines)
