Since the DF64 grinder came out in 2020 it has quickly become one of the top grinders in the world for the home barista.
While there are a couple variations of the DF64, the DF64 original design is still being made and will continue to be made for the home coffee aficionado and works well for someone that likes to drink a range of coffees. With the grind size adjustment mechanism on the DF64, the adjustment will allow users to adjust for coffees that require a very large particle size, such as French Press, to brewing methods that require a very fine grind size, such as espresso.
The large 64mm flat burrs on this grinder provide a large surface grinding area that produces a high quality, uniform grind size, which has a big impact on the extraction and flavor of the coffee being brewed. The DF64 comes standard with stainless steel burrs that work well for a range of coffees, but the 64mm size allows the burrs to be easily upgrades to one of the many 64mm burr set designs that are available on the market today. Some of these burr sets include Gorilla black burrs, SSP High Uniformity (HU) espresso burrs, SSP unimodal multi purpose (MP) burrs, and SSP cast lab sweet burrs with silver knight coating. Each of these burr sets can produce unique flavor nuances that can get the most out of a given coffee variety and roast level.
Another great attribute of the DF64 grinder is that it is a low retention single dose grinder. Single dosing saves coffee and produces better flavored coffee by only using coffee grinds that have been freshly ground. As soon as coffee is ground it starts aerating and losing optimal extraction potential. With traditional grinders that have hoppers or dosers the amount of coffee that is retained between the burrs between uses can be quite a bit. As an example, in a typical double shot of espresso, the amount of retained coffee could be a third or more of the coffee used to brew a shot. With a DF64, where retention / exchange can be about a tenth of a gram, the flavor is usually quite a bit better due to the much higher percentage of freshly ground coffee.
With the simple design and very minimal electronics, the DF64 is a very reliable grinder. While all products have flaws of some sort, the DF64 has proven to be a very successful design, with minimal issues. If one always adjusts the grind size WITH the grinder on, always pumps the bellows at the end of each grind session to keep the burr chamber clean, and always makes sure to keep the threads clean and lubricated, the DF64 can stay problem free for years to come.
There are different versions of the DF64, starting with the v1, v2, v3, and now the v4. With each variation the manufacturer has made small changes to make the grinder more reliable and better performing.
There are also different variations of the DF64, including the two newly released variations, the DF64P and DF64E, both of which are designed specifically for fine tuning the grind size for espresso only. By limiting the grind size adjustment to just espresso, users have the ability to fine tune the particle size, but it also keeps the burr distance very stable with very little tolerance, making it a very low retention grinder with great particle size distribution. See the main DF64P page for a section comparing the DF64 to the DF64P.
