I'm researching the difference between premium manual grinders and cheap manual grinders. In simple language, what is the 'technology' that allows for consistent grounds on premium grinders that the cheaper ones lack?

  • Are we talking about all kinds of grinders or just burr grinders?

  • To elaborate on Stephie's question, grinders marketed as coffee grinders are sold in three main variants: blade grinder, conical burr grinders, and flat burr grinders. Among these, all higher end variants are burr grinders (for good reason). Are you asking about why some burr grinders are more capable than others, or are you asking about why the cheapest coffee grinders (blade grinders) are inferior to burr grinders?

The biggest "technology" that can affect a coffee grinder is the burr set (Aka the bit that actually grinds the coffee). With the burr set, there's a lot of factors like

  • The material of the burr set (Different types of Steel, Ceramic etc)
  • The pattern of the cutting teeth is usually specific to each burr set maker.
  • How fine/coarse you can adjust the grind size and the level of adjustability between these two points (stepless / stepped)

While these are the "main" factors, there are other secondary factors like the driving mechanism that makes the actual burr set turn and even just how well the entire coffee grinder is built-in general (like the materials used and body).
