LEARN | Comandante: Nitro Blade vs Ironheart


There are many manual hand grinders to choose from in the specialty coffee industry, but when it comes to grind quality and performance, coffee enthusiasts can’t seem to go past Comandante.

The Comandante C40 Grinder range has a variety of colours, including Wenge and Bamboo, which feature unique patented Nitro Blade burr sets. This collection has been added to recently, with the release of the Comandante C40 Ironheart, which features a brand new Carbon Blade burr set design. But why the new design?


Both burr sets are adjustable for over 60 grind grade selections. This is perfect for all types of brewing methods; from a fine grind size for Turkish coffee, to a courser grind for French Press. However, there are some differences between the Nitro Blade and the Carbon Blade. As their names suggest, the two types of burr sets are made from different materials. The Nitro Blade burrs are is made out of high-alloyed, high-nitrogen stainless steel. Due to these materials, these burrs are completely neutral in chemical taste, because they don’t react with coffee acids. The Carbon Blade burrs are made out of ultra-hard carbonic steel, making it extremely easy to achieve a very fine grind size.


When it comes to visual appearance, the Nitro Blade comes in an array of colours with real wood veneering on the body, while the Carbon Blade Ironheart is available with a brushed stainless steel body. With the Ironheart, you also have a choice of either a sword or a heart design on the body, printed in black. When it comes to the burr frames, both models have been made using BPA-free, Tritan copolyester. These are black in the Nitro Blade and transparent in the Ironheart Carbon Blade.


Choosing between the Nitro Blade and the Ironheart comes down to how you like to drink your coffee. Due to the chemical neutrality of the high-alloyed, high-nitrogen stainless steel, it is recommended that the Nitro Blade burrs are used for brewing methods such as filter or French Press, where the flavours are more delicate. For the bold and acidic flavours of espresso, the Ironheart would be more suitable.
