FrontStreet Coffee - Electric vs. Manual Coffee Grinder Selection

Coffee grinders can be classified by power source into manual and electric types. Common blade types include flat burrs, conical burrs, and ghost tooth burrs. Different blades affect the flavor of ground coffee beans, so you can choose different blades based on your requirements for coffee flavor.

A high-quality coffee grinder should possess three key characteristics: uniform grinding, fast speed, and excellent heat control. A coffee grinder grinds coffee beans into uniformly sized coffee particles to allow hot water to extract flavor components from the coffee grounds as it passes through. Basically, the finer the coffee beans are ground, the greater the contact area between coffee grounds and hot water during brewing, resulting in more complete extraction of coffee aroma. Conversely, when your coffee beans are ground coarser, the contact area between coffee grounds and hot water becomes smaller, leading to lighter coffee extraction.

This principle can be understood by comparing one coffee bean cut into 100 fragments versus 1000 fragments - the 1000 fragments have a larger contact area with the external environment. After understanding the impact of coffee grind size on extraction, you can adjust the grind coarseness based on your preferred taste and brewing method. So, with coffee grinders available at various price points on the market, how should you choose the right grinder for your needs?

Manual Coffee Grinders

The advantages of manual coffee grinders include their small size, portability, easy disassembly and assembly, no electricity requirement (generating less heat), and reduced loss of aromatic compounds. The disadvantages are the time and effort required for manual grinding, and limited grind size options. Coffee grounds from manual grinders are more suitable for brewing methods like pour-over, siphon, and French press. They may not perform well for espresso.

Common materials for coffee grinders include wooden boxes, iron, plastic, and glass. Wooden box grinders have the disadvantage of not being washable, leading to oil residue from coffee beans, which can develop an oily smell over time and affect the quality of ground coffee. For iron materials, attention should be paid to cleaning and checking for rust after long-term use. Rust can affect taste, and iron filings may also pose health concerns. There are also many grinders made from glass and plastic combinations on the market, which can be rinsed to avoid oil residue and are recommended for beginners.
