An Introduction To Coffee Grinders

When it comes to coffee grinders, there are two main types: blade grinders and burr grinders. Blade grinders are the less expensive option and work by using blades to chop up the coffee beans. Burr grinders, on the other hand, use two revolving abrasive surfaces (called burrs) to crush and grind the beans. Burr grinders produce a more uniform particle size, which results in a better-tasting cup of coffee.

There are also manual and automatic coffee grinders. Manual coffee grinders require you to do all the work yourself, but usually produce a better quality Grind than their electric counterparts. Electric coffee grinds tend to be more expensive but save you time and effort.

The best way to select a coffee grinder is to think about how you will be using it. If you want something quick and easy for making small batches of coffee at home, then an electric blade grinder might be your best bet. But if you’re looking for a grinder that will give you consistent results for large quantities of coffee or for specialty brewing methods like espresso or Turkish Coffee, then you’ll need to invest in a good quality burr grinder.

When it comes time to actually grind the beans, there are several factors that will affect the quality of your final product: coarseness, contact time, dose, distribution, and fines.

Coarseness

How fine or coarse your grind is will have a big impact on both extraction yield as well as taste. A very fine grind can result in over-extraction and bitterness while a too coarse grind may under-extract causing weak flavorless coffee. The ideal grind depends on both your brewing method as well as a personal preference so it’s important to experiment until you find what works best for you. In general, darker roasts do better with coarser grinding while lighter roasts benefit from finer ones.

Contact time

This refers to how long hot water is in contact with grounds during brewing. Longer contact times usually result in more extraction (and thus stronger flavor) while shorter ones produce weaker drinks.

Dose

The number of grounds used also affects extraction yield: using more grounds will lead to a greater extracted beverage while too little may under-extract causing weak coffee.

Distribution

This has mostly to do with commercial Espresso machines where an even tamping pressure is crucial for producing evenly extracted shots. For home brewers, just make sure not To compress your grounds too much or pack them too loosely into whatever filter basket or device you’re using.

Fines

These are tiny bits of ground coffee that can end up over-extracting and making your beverage bitter. Most high-quality grinders should have few if any fines but if yours does create them, simply give your grounds an extra shake before brewing so they settle at the bottom of whatever container they’re in.

Now that we know all about different types of factors influencing the final cup of coffee.
