There are several factors to consider when purchasing a coffee grinder for use at home. They include: - Consistency: A good quality grinder should produce consistent results whether you have it set for fine or coarse grinds. - Capacity: Consider how much coffee you usually make at a time and try to match the right size grinder for your needs. - Speed: If you're in a hurry, you'll want a grinder that can move as fast as you. Or maybe you are not in a hurry and the speed of the grinder won’t matter. But it is something you may want to factor into your purchase. - Noise: Some grinders are louder than others. If you're making coffee in a quiet setting, or do not wish to disturb anyone, be sure to check the noise level before purchasing your grinder. - Ease of Use and Cleaning: The easier it is to operate and keep clean, the more likely you will use it. Plus, a grinder that has simple operation and can be cleaned easily will cut down the time and effort you must put into maintenance. - Budget: Coffee grinders can cost anywhere between $20 and $500. Set a budget in advance and see if you can find one to fit it that does everything you expect from a coffee grinder. - Grinder Type: There are two basic types of coffee grinders: blade and burr. Blade grinders are less expensive and less precise. Burr grinders cost more but are more consistent and better at grinding coffee beans.
