Have you ever had a cup of coffee that was made freshly ground? The difference between pre-ground and freshly ground coffee is astounding!
Coffee beans grow with a protective shell that keeps the coffee oils inside of the bean. Once a coffee bean has been cracked, or ground, the flavor, and aroma begins to dissipate, and other issues, such as contamination and dilution become possible. This is why pre-ground coffee usually comes in a sealed package. But, once a sealed bag is opened, and oxygen hits the product, the process of losing flavor and quality starts all over again.
This is why pre-ground and freshly ground coffee is so different in taste and smell.
Why Grind Coffee?
It is estimated that coffee loses 60% of its aroma and taste within minutes of being ground because of oxygen. Grinding your own beans means you keep 100% of the flavor.
What’s more, coffee loves water and moisture. Any moisture that comes into contact with ground coffee is absorbed and begins to dilute the oils. This also makes coffee susceptible to absorbing other flavors around it. Remember that onion you cut last week that is smelling up your refrigerator? Your absorbent beans are taking it all in, and your coffee will taste a lot more like an onion than you’d like.
The solution to issues such as these is simple. Grind fresh coffee every morning.
Are There Different Types of Coffee Grinders?
Coffee grinders come in all shapes, sizes and forms. The three most common types are disc, burr, and blade. In addition to the types of grinding each device can offer, there’s also the way the grinder operates to consider. Electric and hand grinders are often chosen based on preference. The question you have to ask yourself when it comes to how you’ll grind your coffee, aside from the type of blade you’ll be using, is simple. Do you want to hand crank or simply press a button?
Blade grinders are often the most inexpensive form of coffee grinder. They come in a wide range of pricing and functionality. These grinders are also known for their inconsistent grind. They typically have everything from a powder to a course remnant in each batch.
Burr grinders are also typically electric. They often feature the ability to grind the coffee in a wide range of thicknesses. Unlike the blade grinder which delivers and inconsistent grind, burr grinders will do what you ask of them. Your preference can be anything from barely ground to a fine powder based on your choosing. And, because they are almost always electric, the arm work is taken out of the equation.
Disc grinders are the industry favorite due to their ability to grind the coffee evenly. They are also the most expensive coffee grinders on the market. The even grind means you’ll be able to extract the most flavor from your beans when you brew. This feature alone makes the disc grinder a favorite among coffee lovers.
Taking care of your coffee grinder is as simple as wiping them out when you’re done grinding. Since coffee grounds love to collect moisture, it’s important to keep the inside of your grinder clean to avoid mold and other issues.
It’s important to note that coffee beans that have been coated with flavoring will leave residue in your grinder. This residue often sticks to the blades of grinders and can reduce the life of each device. Additionally, these flavorings will most likely attach to the grounds produced in the coffee grinder after their batch, leaving a slight taste in the coffee grounds that follow.
