The CafeSing GRIZZ-63 is a manual coffee grinder featuring a large,
innovative 63mm conical burr designed to produce high-quality coffee powder for espresso and pour-over, enhancing flavor and body.
This grinder is great value - $200 AUD from Amazon
capacity: Light-roast beans 36g, dark-roast beans 30g
There is a total of 72 clicks in one turn; 16-micron per click
The Burrs rub between setting 0-2
Espresso: setting 3-6 (clicks 24-48) on the first turn.
Pour-Over: setting 1-4 (clicks 80-104) on the second turn
I bought this for espresso.... usually my setting is about 4 (depends on the coffee)
At a setting of 3 my Grind time takes about 1 min for 18g dark roast (if I'm feeling fit).
At a setting of 4, my grind time is about 45 secs
Sometimes I go as low as 2.1.
This is only at settings between 2-4 so there is plenty of "room" to go even finer ....
....so it's really good for espresso.
Usually my setting for Espresso is 4.5. So the grind time is fairly quick ... about 35secs.
I reckon this is pretty quick for a hand grinder. My Comandante c40 takes about 2 mins.
I think the speed is due to the very large 63mm conical burr and its aggressive cutting pattern
The 4-Layer Cutting Pattern burr design helps achieve excellent particle size distribution and shape, reducing bitterness.
It's made of SUS420 stainless steel.
8 core, octagonal burr
According to the manual, the grinder can be easily taken apart and reassembled without tools, simplifying the cleaning process. .... So I guess I'll soon find out.
In comparison, Mazzer produce a 63mm conical burr (191c)
that is used in their Kony S grinders.
Very different design to the Grizz63. The Grizz's cutting pattern looks more aggressive
The Niche zero also uses 63mm conical burrs.
I understand that the Niche also uses the same Mazzer Kony 63mm burrs
Also, according to the manual:
It's Particle Shape: Three-dimensional polyhedrons with microfractures
Particle Size Distribution: Relatively wide distribution.
The Niche has more of a bi-modal distribution pattern.
Main Drawback: At high temp, flavors can become muddled
4-bearing fixed axis for high concentricity
Body Diameter-Height-Handle:
2-7-6.5 in (50-178-165 mm)
Durable Construction:
Features an all-metal construction, including a powder-coated body and stainless steel burrs.
Performance & Benefits
The burr design was previously only found in large electric grinders.

How to open the grinder:
First, adjust the hand grinder to a coarser setting—for example, set it to number 8.
Next, remove the powder cup, then use one hand to push up against the lower-burr while turning the top nut with the other hand.
If it’s a single-layer nut without a ball-bearing washer, turn the top nut clockwise to remove the spindle and lower burr; if it has a ball-bearing washer, turn it counterclockwise.

Grinder adjustments for Espresso:
Many grinders have a 30-micron increment that can be too coarse for dialing in espresso.
In general, the lower the the microns per click, the better your grinder will be for espresso.
By increasing the threads on the adjustment axle, we can increase the number of available adjustment settings thus making it easier to achieve the very precise grind sizes needed for espresso.
A good grinder adjustment for espresso is a step size that's between 5 and 15 microns per click to allow for precise dialing in the shot. Though some grinders are stepless, offering infinite adjustment. The best adjustment size depends on the specific grinder and the sensitivity of your espresso setup, as a single click can significantly affect your shot time and flavor.
Examples of Grinder Adjustments
Kinu M47: each full revolution having 50 divisions,
resulting in a precision of approximately 5 microns per click
1-Zpresso Jmax: 8.8 microns per click
1-Zpresso J-Ultra : 8 microns / click
1-Zpresso JE-Plus & JX-Pro : 12.5 microns / click
Comandante C40: 25-30 microns per click
Comandante C40 with Red Clix: 15 microns per click
HG-1 by Weber Workshops : 13 microns per click
CafeSing Grizz 63 - 16 microns per click
Pietro by Fiorenzato : 15 microns/click
Timemore C3 (standard not the ESP version): 83 microns per click
Timemore C3 ESP: 23 microns per click
Timemore C5: 31 microns per click
Timemore C5 ESP: 15 microns per click
