About the manual coffee grinder, which is better: ceramic or stainless steel burr?
We clearly know that the coarseness of the coffee bean grind affects the extraction of coffee, so now let’s explore how to choose a manual coffee grinder, understand the advantages and disadvantages of stainless steel and ceramic burr, and prepare the ground for brewing a perfect cup of coffee!
Manual coffee grinder with ceramic burr
Advantages
Temperature: high speed rotation heating up slowly, the temperature is relatively stable
Deformation: Ceramic is not easily deformed after heating up, and the shape is relatively normal
Cost-effectiveness: in general, the grinder with stainless steel core is cheaper than the grinder with ceramic core.
Manual coffee grinder with ceramic burr temperature is relatively low, will not be the second heating of the coffee powder; the price is also relatively cheap, suitable for beginners to use.
Disadvantages
Noise: compared to ceramic core coffee bean grinder, the noise is relatively larger
Hardness: the inner core is ceramic, a little less hard than stainless steel blades, with a certain degree of flexibility.
Fragile: coffee bean grinder with a very high breakage rate. Especially when the coffee beans have foreign objects (stones, nails, etc.)
Grindability: uneven grinding
The ceramic core coffee bean grinder is only suitable for home use, not for commercial use.
Manual coffee grinder with stainless steel burr
Advantages
Noise: relatively low noise, relatively more quiet
Hardness: the burr is stainless steel, relatively hard, not easy to wear.
Grinding degree: stainless steel burr has a knife edge, coffee bean grinding coarser and finer relatively more uniform
Coffee bean grinder with stainless steel burr is sharper and quieter to use, but relatively expensive and more suitable for daimler and commercial use.
Disadvantages
Temperature: high speed grinding coffee beans, heating up relatively quickly, the second heating of the coffee powder
Deformation: coffee bean grinder with stainless steel burr heats up faster, which can easily lead to core deformation
Cost-effectiveness: in general, grinders with stainless steel burr are more expensive than grinders with ceramic burr.
