Every devoted java fan knows that getting the perfect cup requires a lot of steps--and the incentive to tackle them during a bleary-eyed morning is often low. Coffee makers that have built-in grinders make it easier to understand the process, removing the need for measuring and grinding beans in advance.
How to Grind Coffee
If you're trying to create the most delicious coffee, it's important to grind your beans prior to the coffee is brewed. Grinding your coffee beans can increase the surface area as well as alters the size of the particle, making it easier for the water to mix with the coffee and extract its flavors. The time between grinding and brewing can influence the quality of your coffee. If you grind your beans before time, they will rapidly become oxidized, which will ruin their flavor.
The kind of grinder you choose can affect how coffee is ground. Blade grinders and Burr grinders are the two primary types. Burr grinders are made up of rotating burrs which grind beans into small, uniform particles. They generally are quieter and more consistent than blade grinders.
Blade grinders, made up of propellor-like blades that cut beans into smaller pieces. They're typically louder and less reliable than burr grinders. However, they can be a cost-effective alternative.
It is crucial to only grind the amount of coffee you need at any given moment. Certain grinders have hoppers with various capacities, which impact how many cups or shots can be ground simultaneously. Different grinder models may also require different amounts of effort to adjust the size of the grind.
If you have a burr grinder, you can adjust particle size by turning the collar on top of the grinder. This will allow the burrs to be moved closer or further apart. You can also play around with the settings until you find one that works for your brewing method.
Depending on your brew method it's likely that you'll need to experiment with various grind sizes before you find one that is delicious. Manufacturers and coffee experts might have suggestions but ultimately it's your choice to choose a blend that suits your taste. You might have read that a French Press works best coffee bean grinders with coarsely-ground coffee, or that espresso requires fine-ground coffee. However, those recommendations aren't necessarily accurate: Different brewers require different amounts of heat and water to extract the flavors they create.
Burr Grinders
A burr mill is made up of two components that lock two parts, one stationary and the other rotating. The sharp surfaces on both parts crush beans as they pass through. This gives you a very precise control over the size of your beans, a crucial factor for a variety of methods of brewing. It also produces less heat than blade grinders and preserves the coffee's flavor.
There are two kinds of burr grinders: conical and flat. Conical burrs are conical rings that have serrated edges. They grind against each other to produce a fine-to-medium grind. They are found in the majority of home grinders. Flat burr grinders feature two identical rings that are serrated and grind against each other, producing a medium to coarse grind. These can be found on a number of larger commercial grinder grinding machines.
The two kinds of burr grinders differ in their geometry, which ultimately affects the distribution of grind sizes produced. They also run at different speeds, which may alter the taste of your coffee. A top burr grinder is designed to spin at a lower RPM that means it produces less heat and static. A lower-quality grinder will spin at a much faster speed, which can cause the burrs stuck together and leave an odour that can alter future batches of coffee.
The two types of burr grinders are constructed from ceramic, metal or a mixture of both. Metal burrs tend to be more durable and less susceptible to damage, while ceramic is more fragile and can crack or chip when it comes into contact with small stones or other particles.
Most people select the burr grinder because of its ability to create an even, consistent grind. It can take a while to get the perfect consistency, and you may have to adjust the settings of your grinder as it operates. After each use, wash the grinder to remove any uncooked beans or overly roast ones that may have gotten stuck between the burrs.
It is important to keep in mind that the granules in your coffee will be affected by the temperature of the water used to brew. If the water is too hot, it will burn the granules and change their taste. The ideal temperature for brewing is around 195 degrees Fahrenheit.
Blade Grinders
Like the name suggests, these grinders use a blade that spins to chop the beans. They resemble miniature blenders and are popular because they tend to be cheaper and take up less space than burr grinders. They also work well for those who don't intend to drink their coffee black and prefer to add sugar or other flavors.
The blade grinders don't produce a consistent size of grind. The blades' chopping motion chops some coffee beans into smaller pieces, while others are cut into larger pieces, resulting an uneven mix that could vary in size from fine to coarse. The uneven distribution of size can result in over- or under-extraction, which can affect the flavor of the cup.
In addition the whirling motion of the blades creates heat that can cause the beans to become burned during the grinding process. This can alter the flavor of the coffee since the beans that have burned less surface area that hot water can interact with and extract.
Blade grinders also generate more dust when they are in use. This can be an issue in kitchens that are packed. This dust could pose dangerous to health as it may contain harmful microbes, which can contaminate the final coffee. The sticky residue that blade grinders leave behind could make them difficult to clean.
Contrary to this, burr grinders depend on two rotating surface abrasives to crush the beans into an even, uniformly-sized ground size. They do this without the requirement for adjustable settings, allowing the user to choose the right grind size based on their brewing method. The uniform grind permits water to pass smoothly through the grounds, resulting in an even extraction of the coffee's flavor. Burr grinders can be more expensive and require more maintenance however, they are more durable. Before you make a decision take into consideration your budget, brewing techniques and the counter space available. It may be worth it to invest in a burr mill.
Dosing Grinders
A dosing coffee mill is one type of coffee mill designed to only grind the amount of beans needed for brewing. This is a very popular type of grinder for home use because it eliminates the need to store ground coffee in between uses, and ensures the beans are freshest when they are brewed. This can aid in achieving optimal flavor extraction and decrease the amount of waste.
To do this, the grinder comes with a built-in chamber that is designed to catch and hold the coffee ground before it is dispensing into your portafilter. This chamber is usually located near the top and is comprised of six sections that are equal in size. As the coffee leaves the burrs that grind it falls into one of the sections. A handle can be pulled that controls the speed at which the sections move. As the sections rotate the ground coffee is dispensed to your portafilter.
There are a few grinders available on the market that can do this well and tend to be at the top of the line in terms of consistency and quality (Titan class). There are a lot of grinders that aren't good at this and can produce inconsistent results or overfill your portafilter. This is why we recommend using a dedicated espresso grinder that only makes one dose. For other types of brewing, it's recommended to simply count the amount needed.
Rancilio Rocky and Gaggia MDF are among the most well-known dosing grinders that are available. They are all excellent options for espresso lovers who live at home. There is also a dedicated single dosing model made by Ceado known as the E37SD that has been getting attention in recent years and was recently described as potentially an "Niche Zero Killer". The E37SD is a massive 83mm OpalGlide coated burr that creates constant grinds and virtually zero retention. It can be adjusted for any brewing method.
