Do coffee grinders get dull? Yes, they do. As often mentioned, coffee grinders begin to experience subtle changes over time.
One of these changes is the blade grinder becoming dull. This happens because coffee beans tend to lose their distinct flavors as time goes on. Ideally, this change is gradual and slow but sometimes, you could pick up on it’s odd taste. Dull blade grinders simply cannot properly grind the coffee beans into powder, thus, hindering all of the wonderful flavors and distinctive aromas that come with the drink.
Another common complaint about some coffee grinders is that the coffee grinders tend to become unbalanced. You grind and then the beans fall out of the grinder. This is actually balanced by a counterweight system to keep the grinding plates from sticking together. However, when the plate becomes unbalanced, the grinding will stop and then the beans will be ground flat. The result? A bitter tasting cup of Joe.
Many people don’t realize that the smaller the particle size of the beans, the more flavorful they will be. These larger particles, or beans, are easier to grind into fine particles for proper brewing. As a rule of thumb, if you want a bright and robust cup of coffee, start off with coarse (larger in particle size) beans. If you like a smooth consistency, go with finer grained coffee. When brewing espresso you should always use very fine grounds to achieve the best results.
Many coffee grinders also tend to be less durable than some other types of grinders. It’s not that they don’t last long but that they don’t hold up as well. Some of the cheaper grinders tend to have plastic parts and plastic grips which can easily warp and wear. Other types of grinders come with metal parts and plastic handles. While these types are less likely to warp, over time they can start to look rusted and old.
Conical burr grinders tend to last longer and are generally made from solid steel. These grinders can produce a finer grind and produce more aroma from the grounds. Some conical burr grinders can even be used to replace standard grinding stones. These grinders can work with coffee grounds of varying sizes and produce a better-tasting cup of Joe.
Dull coffee grinders or damaged grinders can affect a coffee maker’s overall taste. When a coffee maker is used regularly, it can be a deciding factor as to whether or not a person drinks coffee. Grinding stones are designed to sharpen coffee grinders blades so they can produce a higher quality of grind. The sharper the blade, the more coffee flavor will be extracted. Even though this might not seem like much of a factor when choosing a coffee grinder, it can make a world of difference in the final taste of a coffee drink.
If a coffee maker needs to be maintained then it’s important to look for specific parts that may need to be replaced or repaired. Some of these include switches, drive belts and glass covers. The switches on most grinders are meant to automatically switch the grinding unit to the correct speed. Drive belts are designed to reduce the amount of friction that can shorten the life of both the grinding unit and the coffee beans. These parts can be expensive to repair but it can often be worth the extra expense to have a good grinder.
Another important part of coffee making that can contribute to the quality of the final brew is the quality of the coffee grounds. Most coffee grounds sold in stores are generally low in acidity. This makes them ideal for brewing strong coffee, like espresso. However, when coffee grounds are overly acidic they can actually alter the taste of the coffee.
The last major component in coffee grinder blades is the type of rice to be used in the grinder. The rice must be a finer grain so it retains more of the oils produced during the grinding process. It is also best if the rice is unsalted, since the oils from the ground rice will evaporate and leave behind residue. To test how your coffee tastes, it is best to brew a cup of coffee and add a small amount of water. If the coffee tastes bland, adding a teaspoon of sugar or other natural sweetener to the water will bring out a more pleasing flavor.
In general burr grinder machines work better than blade grinders. These types of grinders produce smaller particles with each hit. Blade grinders can create very large particles that can clog filters or other parts of the grinder. While both type of grinders can produce top-quality results, many coffee enthusiasts prefer the smoother consistency produced by burr machines. When deciding which type of grinder is best for you, it is best to read coffee shop reviews to find out what type of grinders have been found to work best for other consumers.
