Grinding freshly roasted whole bean coffee is a crucial step for brewing a delicious cup of coffee. Here's some tips to help you master your coffee game at home!
1. Never, ever, ever pre-grind your coffee. Coffee stales and deteriorates in quality much faster once ground. To ensure the highest quality cup of coffee, always buy freshly roasted whole bean coffee and grind it just before brewing. It is also ideal to store your whole bean coffee in an airtight container to help maintain the quality even longer.
2. Grinding and grind consistency is key. Consistent and uniform grind size is essential for brewing great tasting coffee. Each brewing method and/or type of coffee requires a different grind. Here is a simple quick reference for grinding according to your brew method:
- Coarse Grind: Chemex Coffeemaker, French Press, Percolator
- Medium Grind: Flat-bottom brewer, Auto-drip brewer, Pour Over
- Fine Grind: V60 AeroPress, Espresso
3. It helps to measure and weigh your coffee. For the best results each time you brew your coffee, start measuring out your coffee beans prior to grinding. If you add more beans than necessary you can alter the flavor of the brewed coffee by causing it to over or under extract. This will also help with ensuring a consistent grind size each time.
4. Buy the right grinder. For at home coffee brewing and grinding your own beans at home there's really only two main factors to decide between: burr or blade and automatic or manual. We highly recommend using a burr grinder over a blade grinder. A blade grinder works much like a blender where there are two actual blades at the bottom of the container that spin. These grinders are much less expensive but also much less consistent and less effective. Burr grinders have either a disk burr, two donut shaped rings with razor sharp edges facing each other, or conical burr, a cone shaped burr that feeds into a serrated outer ring. Conical burrs transfer less heat, are much quieter, and deliver more body and richer flavor. Flat burrs are often found on espresso grinders as the allow for a higher percentage of extraction. However, flat burr grinders tend to be more expensive, very noisy, and transfer much more heat. All-in-all, for most home baristas or entry home brewers, a conical burr grinder is the way to go.
