What is the difference between a burr grinder and a blade grinder?

A burr grinder and a blade grinder are two types of coffee grinders with distinct differences. A burr grinder evenly grinds coffee beans by crushing them between two burrs, resulting in a consistent grind size. The burrs can be adjusted to control the coarseness, allowing for a custom coffee experience. On the other hand, a blade grinder uses blades to chop coffee beans, leading to an uneven grind with varying particle sizes. This inconsistency affects the coffee's flavor and brewing process. Blade grinders are often less expensive but lack precision and consistency. In summary, while burr grinders produce a more uniform grind, blade grinders offer a more cost-effective option with convenience at the expense of grind quality.
