Common Questions About Commercial Coffee Grinders
What are the differences between blade grinders and burr grinders?
Blade grinders are economical because they use a spinning blade to pulverize beans and provide no control over the grind. In contrast, the more expensive burr grinders provide precise control over the grind's texture. Blade grinders don't require much maintenance, but burr grinders need to be sharpened by a professional periodically.
Burr coffee grinders produce three main grinds: fine, medium, and coarse. Finely ground beans are powdery and are typically used in espresso and Turkish blends. A medium grind has the texture of table salt, perfect for pourover brews and automatic drip machines. With the texture of granulated sugar, a coarse grind works well with percolators and French presses.
Which coffee bean grinder is best for my application?
Most often used in grocery store aisles, bulk coffee grinders grind beans directly into containers or bags. These units are best if you want to grind several pounds of beans ahead of time.
Portion control grinders grind beans into coffee filter baskets. If you brew drip coffee, this is the best option, but you'll need to ensure that the grinder is compatible with the brewer's basket.
Made to grind beans for an espresso machine, dosing grinders dispense ground beans in 5-ounce and 10-ounce doses. They are typically operated with a lever and dispense into the espresso machine's portafilter.
How do I clean my coffee grinder?
If you don't clean your grinder, impurities can cause oil buildup and leave a stale taste and smell in the coffee.
Most grinders have a hopper that can be removed from the machine. While you clean the hopper, pour the remaining beans into an airtight container. You can then wash the hopper in warm, soapy water. Let it air dry completely or water spots and corrosion may develop on the grinding burrs. After the hopper is clean, brush the grinder until the burrs and chamber are clean and dry. If you want your commercial coffee grinder to be shiny and spotless, you can buff it with paper towels.
