Mahlkönig originated in Hamburg, Germany, in 1924 and is now owned by Stawert Mühlenbau. Mehdi is a traditional family business that produced industrial electric motors in the early days, and later began to focus on electric grinders, and today is a leader in the high-end market of coffee grinders, with 90% of its production line made up of grinders, mainly commercial grinders, known as the "German mill king". In 2007, Stawert Mühlenbau merged with Ditting, a well-known Swiss grinder brand, and then acquired the famous Italian grinder brand Anfim, and today Stawert Mühlenbau is the number one coffee grinder company, with factories in Milan, Italy, Bachenbilach, Switzerland, and Hamburg, Germany.
 
The key to the professionalism of the grinder is the sharpening of the knife, and the grinding uniformity is the most important criterion for evaluating the grinding performance of a grinder. Mehdi uses a laser particle size analyzer to analyze the grinding uniformity of coffee, and these analysis charts can be found on Mehdi's official website, which directly shows the excellent uniformity with data. While the vast majority of grinders are analysed with a bimodal curve, the Mahdi grinder exhibits a unimodal curve, which means that there are a large number of particles of similar volume.
 
Mehdi's grinding series includes EK, K30, VTA, with a minimum price of about 16,000 yuan, with strong grinding consistency and durability, and taking into account the optimization of use details and functions, it is the preferred grinder brand for many coffee shops. In the early days, the grinding efficiency of the grinder was low, and a powder storage bin was generally set up on the powder outlet to facilitate the grinding of coffee powder in advance, so that the supply would not exceed demand. However, most of Mehdi's grinders are designed for direct powdering, which means that there is a stronger grinding efficiency and a low residual powder rate, which ensures that the powder is fresh enough every time it is produced, so that the coffee taste will not be affected by the "old powder".
 
EK series are all using 98MM alloy steel flat knife, one person can grind coffee beans in a few seconds, can take into account the Italian fine powder grinding and hand-punched coarse powder grinding, the lowest price is 18,000 yuan, with strong compatibility and good grinding performance, it has become the most popular series. The EK43 is the base of the EK series and the star of the coffee grinder, which can be used as a professional-grade home or commercial product, and can be found in many specialty coffee shops. However, the EK43 is designed for direct powder and cannot be ground in advance, so if you want to grind quantitatively, you must pre-weigh the coffee beans you need, which is inefficient for busy coffee shops.
 
If you want more convenient and practical features, you can upgrade to EK43S or EKK43 or EK43S. EK43S optimizes the detailed design on the basis of EK43 and increases grinding accuracy, and is the designated grinder of WBC from 2018 to 2020.
 
K30 series is specially designed for Italian grinding, all of which use 65mm steel alloy flat knives, the grinding speed is about half of EK, the direct grinding knife design effectively reduces the residual powder rate, the grinding degree is infinitely fine-tuned, and the grinding can be regularly and quantitatively grinded, which is more convenient to use. The K30 VARIO is the basic model, and the TWIN is upgraded to a double bean bin on the basis of the VARIO, which is practical, saves the trouble of replacing beans, and is very suitable for café use. AIR adds a blowing cooling system to prevent the cutterhead from overheating. The K30 2.0 is an enhanced version of VARIO.
 
PEAK is also designed for Italian grinding, with a double heat discharge system, a grinding accuracy of 0.1mm, easier to adjust the grind than the K30, and the same can be dodified by timing. The PEAK series is very similar to the K30 in appearance, and can be regarded as a super performance top version of the K30, priced at 25,000 yuan. PEAK's sharpening knives are an improved version of the sister company Ditting's sharpening knives, and the triangular shape of the cutterhead grooves has been changed to a near-oval shape, so the ground coffee is more uniform.
 
What really makes Mehdi the "King of Grinders" is the VTA 6S, a commercial giant grinder. This grinder has a huge 120mm high-carbon tungsten steel cutterhead for high grinding efficiency and super durability, making it the first choice for large coffee houses.
