What kind of grinder is better, blade or burr?
The main difference between the two types of grinder is consistency. Blade grinders are a great and affordable way to get coffee ground quickly, but the grind tends to be inconsistent. Burr grinders crush the beans at a high speed through spinning wheels (burrs) resulting in a uniform, more consistent grind. A uniform, even grind is important because it allows a more even extraction during brewing resulting in better tasting coffee.
