A coffee grinder is one of the most important coffee gears you need for making great coffee at home. There are two main types of coffee grinders: blade grinders and burr grinders. While blade grinders are commonly found in households, burr grinders are known for producing a more consistent grind size and are preferred by coffee professionals.
The main difference between the two types of grinders is the way they grind the coffee beans. Blade grinders use a spinning blade to chop the beans into small pieces, while burr grinders use two abrasive surfaces to crush the beans. This difference in grinding method affects the consistency of the grind size.
Blade grinders produce a mix of coarse and fine particles, which can result in uneven extraction during brewing. This uneven extraction can lead to a sour or bitter taste in the coffee. Burr grinders, on the other hand, produce a consistent grind size, resulting in a more even extraction and a better-tasting cup of coffee.
There are two types of burr grinders: conical and flat. Conical burr grinders are more common in households and are generally less expensive. They produce a consistent grind size and are suitable for most brewing methods. Flat burr grinders are found in more expensive models and are known for producing an even more consistent grind size.
When choosing a coffee grinder, it’s important to consider the consistency of the grind size and how it affects the flavor of the coffee. Burr grinders may be more expensive, but they are worth the investment for coffee lovers who want the best possible cup of coffee.
