The Ultra conical burr coffee grinder is a classic grinder for at-home coffee enthusiasts who desire a simple, solid start to make their brews. Its 40mm conical burrs give it an edge in the grinding game, with the capability of producing a more uniform grind quickly so you can enjoy a wider range of brewing styles. Simple grind adjustment and timed dosing make it a fantastic addition to any at-home coffee collection.
This conical burr coffee grinder consists of three main parts: the removable coffee grounds container, the bean hopper, and the unit's main body.
The hopper has a clear plastic body; in the middle of the hopper is a guide cone that directs the beans to go down into the center of the burrs. It can hold up to 300 grams of beans. One noticeable feature is the hopper trap doors underneath; when the hopper is locked, the door is open to allow all the coffee beans to move through the grinder. When you press the button to lift the hopper, the door is closed, and the beans in the hopper will not flow everywhere.
There is a ground collection container. It is translucent, so you can see how much ground you get. It is not completely airtight, do not suggest storing the grounds here for long periods.
This grinder uses 40-millimeter conical shape stainless steel burrs, the cone-shaped center burr with an outer serrated burr helps produce well-ground coffee, and its design is naturally energy-efficient and heat resistant, making it a great option for professional and home baristas. The output speed of the burr at 550 rpm, and an upgraded DC motor with 160 watts, result in a fast grinding of a couple of grams per second and keep the beans cool while pounding. Gear speed reducer decreases noise, adding expanded quality and toughness to the drive transmission. There is also overheating protection inside the unit.
The main body of the grinder is with stainless steel housing. On top, you'll find the conical burrs; you can remove the upper burr for cleaning. There is a locking tab on the side of the bean hopper. To install the bean hopper, align the locking tab to the triangle symbol above the press button on the adjustment ring, then gently turn clockwise to lock.
The grinders use the hopper on top to adjust the grind size. You can twist the hopper to select your grind setting. The gradations for the grind size, from one through thirty around the base of the adjustment ring, and these sections are labeled for different brewing styles, suited for the size of the grinds, from very coarse grounds for the french press to medium grounds for drip or pour-over coffee and fine espresso grounds.
In front of the unit, there is a power symbol button, and the dial points to the dosage or cups of grounds you want. It will end up automatically for the cups you choose. These are set in increments of two ostensibly to tell you how many cups of coffee you can make with the resulting grounds, though it's more of an approximation of quantity based on a set amount of time the grinder runs. If you want to stop it before it finishes, press the power button, and the grinder will not run. The one-touch operation keeps you from having to readjust the timer every time you need some ground coffee.
This grinder measures 12 and 9 inches tall, 5 inches wide, and 7 inches deep; it fits nicely on the counter, not taking up a lot of room. The machine has a simple interface. Just turn a single dial to select the number of seconds you'd like your machine to grind, press the button in the center of that dial to start grinding, and you're good to go. Sure, you need to experiment to figure out exactly how many seconds it takes to grind your ideal amount of coffee, but this process costs way less than getting a fancier grinder with a scale to do the work for you.
Do not suggest making a lot of coffee at once, as it will be fresher to grind before the brew. To store Coffee beans is better to store coffee grounds to keep the aroma. It's all down to your taste to find the exact ideal setting, and results will vary based on your beans, how much water you brew with, and your coffee maker.
The grinder is not noisy, given the motor's power and its grinding hard beans. It'll be a grinding/pulsing sound rather than a high-pitched whine. We recommend using it in an open space where the noise won't reverberate and becomes amplified.
Feed the beans into the grinder's hopper; the two cone-shaped burrs with ridges will grind/crush the coffee. The burr grinder has one stationary burr while the motor turns the other. The beans are drawn between the two burrs and crushed into a uniform size. Then it will automatically drop the ground collection container.
Before changing grind size, for example, from drip coffee to espresso, it's a good practice to empty the grinding chamber first by running it until no more grounds come out. It will prevent you from having inconsistently sized grounds, which could be problematic for some coffee makers.
We recommend cleaning more often to protect your beans' great flavor and ensure a sanitary experience. While your beans may continue to be ground consistently during cleanings, excess oils and grounds can build up and affect the taste of your brew. And it's also good to prevent clogging with the machine. Unplug the unit, remove the upper burrs, then use the included brush to sweep any stray grounds into the center so that they drop through the opening underneath. You can clean the coffee grounds output by gently knocking the side of the grinder and shaking it out the grinder. Your goal here is to dump as many grounds as possible from the grinding chamber. Now remove the grinds bin and dump those out as well. Then use the brush to clean. Never clean your grinder using water, as the metal parts inside can become corroded. Different methods of cleaning exist depending on your particular grinder.
For those seeking the best in freshly made coffee with a unique flavor experience, a burr grinder could be the best idea. The operation and methods are simple but producing a complex flavor of pre-ground coffee cannot match. By creating uniform particles from coffee beans, quality and taste are more apt to be ideal.
We truly hope the above overview on our burr coffee grinder can help you understand the conical burr coffee grinder.
Generally speaking, when we brew coffee, we aim to extract a sufficient amount of desirable soluble molecules from the beans while leaving the undesirable ones behind.
If we don't extract enough of what we want from a bean, the resulting coffee will taste "under-extracted." Under extracted coffee is not necessarily weak coffee. Rather, it's coffee in which an insufficient amount of the desirable soluble molecules have been pulled out of the beans and dissolved into the water. If you brew a high ratio of coffee beans in water but under-extract them, you could end up with both strong and under-extracted coffee, a seemingly contradictory concept. Under extracted coffees taste sourer—and not in a good way.
Over extracted coffees, on the other hand, have pulled too much from the beans, including unpleasant things we don't want in the cup. Those coffees often taste harsh and bitter. And just like the seemingly antithetical possibility of a strong under-extracted coffee, you can have a weak over-extracted coffee, say, by brewing a small amount of coffee relative to the water for too long. It should go without saying that you can also have weak under-extracted coffees, strong over-extracted ones, and everything in between.
A grinder plays an important role in coffee extraction because it determines the grind size of the coffee. Grind size can affect extraction in two ways. The first is perhaps the most obvious: Finely ground coffee has far more surface area than coarsely ground coffee, and that increased surface area makes what's in the beans more immediately accessible to the hot water, speeding up the extraction rate.
The second thing the grind size determines is the flow rate for certain methods of coffee brewing, such as pour-over, which, in turn, affects extraction levels. The smaller the coffee particles, the more slowly water can seep down through them; the larger the coffee particles, the faster. If you imagine two pipes, one of which is packed with sand and one that's packed with marbles, and you poured water through each, the water would pass much more quickly through the marbles than the sand, given all the space around them. With coffee, the water traveling more slowly through the finer grounds has more time to extract coffee molecules, while the water racing through a coarsely ground coffee will have less time.
How coarse or fine to grind coffee depends on complex factors, including the batch size, the brewing method, and the coffee beans themselves. It's a moving target and therefore takes some practice to understand how to use grind size to improve your coffee.
As you are probably starting to see, given how grind size can determine surface area and flow rate, and thus extraction, a grinder that offers a wide range of grind sizes and produces a uniformly sized result at each grind setting is desirable. If a grinder produces coffee grounds with too much variance in size for any given grind setting, results become increasingly difficult to control. A setting meant to produce a medium grind but instead gives that medium grind littered with fine powder and too-big chunks may under- or over-extract, or both. At least, that's the theory.
Exactly how uniform coffee grounds need to be is open for debate, and it's something professionals in the coffee industry continue to explore. If we can say one thing with certainty, we want a grinder that helps us produce a cup of coffee that we consider enjoyable and delicious.
