Burr grinders that are cheap are worth investing in. For a coffee lover who's very picky about their coffee, investing in a higher-quality grinder is probably the best choice. The manual grinder performs better than the electric grinder. It will be easier for you to control how your beans are ground. With manual grinders, you can get finer grinds than with electric grinders. To achieve the finest grinds, you will need extra elbow grease, but it will be well worth the effort in the end.
