It really depends on how discerning of a coffee drinker you are. Because it produces a more even, consistent grind, a burr grinder typically produces better-tasting coffee. It also doesn’t generate any heat, so you don’t have to worry about the beans possibly having a burnt flavor. Due to the coarse, uneven grind with a blade grinder, you may wind up with grounds in your coffee cup if you opt for a model with that type of grinder.
