Coffee, one of the world’s most beloved beverages, has a history that spans centuries. Throughout this rich history, people have devised various methods to grind coffee beans, from the earliest mortars and pestles to hand-cranked grinders and modern electric ones. Regardless of the tools, freshly ground coffee beans have always been the key to brewing a delicious cup. Today, we will focus on a modern portable burr coffee grinder - the Mulli KF-YM-01, which will bring you a whole new coffee experience.

Coffee culture has a profound impact worldwide, with each region and country boasting its own unique coffee traditions and rituals. From Italian espresso to Turkish coffee, Vietnamese drip coffee to American iced coffee, coffee has transcended being a mere beverage and has become a lifestyle and cultural symbol. Coffee grinding, as a crucial step in the coffee brewing process, also plays different roles in different cultures.

In some cultures, coffee grinding is considered a ritual that requires patience and skill. For example, in Turkey, the coffee grinder (kahveci) uses a special hand grinder to grind the coffee beans into a very fine powder, which is then slowly cooked in a copper pot called a cezve. In other cultures, coffee grinding focuses more on efficiency and convenience, leading to the advent of electric grinders.

The Art of Burr Grinding

Burr grinders work by crushing coffee beans between two abrasive surfaces (burrs). Unlike blade grinders, burr grinders do not generate excessive heat, thus preserving the flavor of the coffee beans. Moreover, burr grinders offer more precise control over the grind size to suit different brewing methods.

The Mulli KF-YM-01 uses ceramic burrs, which are known for their durability, sharpness, and resistance to rust. With a hardness second only to diamonds, ceramic burrs maintain their sharpness for a long time, ensuring consistent grinds every time. This is crucial for coffee extraction and flavor.

Grinding Experience

In testing, the Mulli KF-YM-01 Portable Burr Coffee Grinder produced uniform, consistent grinds at all settings. The grounds had minimal fines and maintained an even particle size. It took 2-3 minutes to grind enough for one cup, a reasonable speed for a portable burr grinder. Additionally, the transparent hopper allows you to see the grinding process, ensuring you are satisfied with the grind size. The burrs didn’t overheat during grinding, which is important because excessive heat can degrade the flavor of your coffee.

Besides being battery-powered, the Mulli KF-YM-01 also comes with a manual hand crank in case of low battery. This adds to its versatility, allowing you to enjoy freshly ground coffee even when you don’t have access to a power source.

Burr Grinding Mechanism

The Mulli KF-YM-01 utilizes a burr grinding mechanism instead of traditional blades. This mechanism ensures that the coffee beans are crushed evenly between two burrs rather than being haphazardly chopped by blades. This results in uniform coffee grounds that are essential for optimal flavor extraction. The ceramic burrs are known for their durability and ability to stay sharp, ensuring consistent results with every grind.

Adjustable Grind Settings

The Mulli KF-YM-01 offers 5 grind size settings, ranging from fine for espresso to coarse for French press. This versatility allows users to customize their coffee grind according to their preferences and chosen brewing method. Whether you prefer a strong espresso or a full-bodied French press coffee, this grinder has got you covered.

150W Motor with 78 RPM Speed

The Mulli KF-YM-01 is equipped with a 150W motor that operates at a speed of 78 RPM. This slow grinding speed helps to preserve the flavor of the coffee beans, preventing them from overheating and becoming bitter. Additionally, the lower speed also helps to reduce noise, making the grinding process quieter.

Visual Operation and Auto Stop

The Mulli KF-YM-01 features a transparent design that allows you to monitor the grinding process, giving you better control over the grind size. Additionally, it has an auto-stop feature that automatically stops the grinder once the grinding task is complete, eliminating the need for manual intervention.

Battery Level Light

The Mulli KF-YM-01 is equipped with a battery level light that indicates the remaining power percentage. This allows you to know exactly when you need to recharge, ensuring that your grinder is always ready to use when you need it.

Hopper Capacity

The Mulli KF-YM-01 has a hopper capacity of 150 ml, which can hold 22-33g of coffee beans, enough for 1-2 cups of coffee. This is sufficient for personal use or small households. The transparent hopper allows you to clearly see the remaining amount of coffee beans, making it easy to refill when needed.
