How long does it take to grind a full dose on the Royal?

Depending on your personal strength/speed of rotation and the roast and dose being used, grind times will vary. For example, a light roast is typically harder compared to a dark roast, and will therefore take slightly longer to grind finely. 

In general, it will likely take you 45 sec-1.5 min to grind your dose. 

Tip: You can "automate" your Royal by substituting the crank assembly for a power drill and matching bit. Insert the bit where the crank assembly usually goes, and hold the Royal body securely in place to grind "electrified"!
