Grinding Coffee

The Grinders

Blade Grinders

The word “blade grinder” is sort of a misnomer since there really is no actual grinding going on. This type of grinder is more like a blender for coffee beans. Blade grinders are very popular because they are cheap, readily available, and easy to use. However, blade grinders have serious drawbacks. First and foremost, they offer very little control. Basically, you are guessing how long you want the blades to hack the beans apart. Instead of a consistent, even grind, you can easily get chopped chunks mixed with powder. Also, blade grinders produce a lot of friction which produces heat. Heat actually starts to rob your coffee of its aroma and essences before it’s even brewed. Grind your coffee with a blade for long enough, and you may even be able to detect a “burnt” taste.

Burr Grinders

The best and most common burr grinder is a conical burr grinder. These devices actually crush the beans between a moving surface and a non-moving surface. The positioning on the burr is what regulates the ground size, which allows for a more consistent grind. Since the beans are being crushed rather than sliced, there is not a noticeable increase in heat when using a burr grinder, so there will not be a burnt taste or a loss in flavor.

Coffee roasters and commercial coffee companies use burr grinders, and they are available in all sizes from large commercial grinders to counter top models. While you could get away with using a blade grinder for brewing coffee in a drip machine using paper filters, you should certainly only use a burr grinder if you are brewing coffee with a French press or using a permanent filter.

Life has taken me in a direction I would have never picked for myself. I was born in a land that they described today as a war zone and raised by the strongest baby boomers of their generation. Graduated from a school of hard knocks a year early and fell into the arms of a transformed man. Found God then turned my back and crawled back when I realized I couldn’t do it by myself. Married a man who pulled out my gifts and helped me strengthen my talents and we introduced our version of ole blue eyes. We started selling coffee but this time without the siren on our backs and created our own brand of coffee that we occasionally sale at our community events. My life story is a secret but if you follow closely you just may see me.
