  • Q04: Why do the flat burrs get stuck after installation?
  • A04: The Orca grinder is compatible with both flat burr and ghost burr. If you're installing a flat burr, adjust the grinding dial to the smallest setting clicks-1, tighten the bottom knob of the lower burr, and loosen it just 2-3 notches - that way, the upper and lower flat burrs won't get stuck together.
  • Q05: Why does the GRIZZ grinder use 38mm not 48mm conical burr?
  • A05: The 38mm conical burr is more labor-saving than the 48mm one, and labor-saving is one of the essential considerations in a hand grinder.
  • Q06: If ORCA grinder can use 64mm SSP flat burr?
  • A06: Please refer to this design review: https://cafesing.com/blogs/user-manual/orca-flat-burr-design-review
  • Q07: Why is ORCA’s grinding adjustment 18 microns per click, not 8 microns?
  • A07: Guess what the grinding adjustment of the C40/Omega grinder is? The core of a hand coffee grinder is the burr, and different burrs are different chefs.
  • Q08: I am a coffee rookie, plan to make my coffee at home. Is ORCA suitable for me?
  • A08: Not a good choice. Beginners should buy entry-level conical burr hand grinders and entry-level espresso electric grinders. After you make and drink more than 6 kinds of high-quality beans, you will establish some taste appreciation; using ORCA at this time, you will discover a new world of taste.
  • Q09: Shouldn’t I use an electric grinder to make espresso?
  • A09: If you don’t operate a cafe, if you home make 2 cups of coffee a day like me, it’s best to use a hand grinder. good electric grinder is 10 times the price of a good hand grinder, X times the size, X times the difficulty of cleaning, and X times the difficulty of maintenance.
  • Q10: Why need to make coffee at home? Isn’t takeaway coffee good?
  • A10: I drink 4 cups of takeout but only 1 to 2 cups of homemade coffee daily. I have to tip for some takeout, but at home I can choose the beans and no tip.
  • Q11: Will ORCA release a new burr?
  • A11: We are designing and expect to release a new ORCA burr in 2024
  • Q13: What equipment do you use to make coffee at home?
  • A13: 
  • Espresso machine: Flair58 electric version, electric preheating, manual pressure change;
  • Pour-over coffee maker: V60 plastic version, fast flow rate, fast heating;
  • Hand Coffee Grinder: ORCA;
  • Coffee Scale: OWL;
  • Temp Kettle: Fellow or Timemore, Fellow has a small water flow, Timemore has a large one;
  • Coffee Beans: Not recommended; even reputable roasters can have bad batches.
  • Q14: Can ORCA Ghost Burr to make espresso?
  • A14: No. If you insist on using it in a semi-automatic espresso machine, ORCA can produce a taste similar to the Aeropress.
  • Q15: Why OWL scale no Bluetooth? Will it be available in future versions?
  • A15: OWL no Bluetooth, and not in the future; why do you need Bluetooth in a coffee scale?
  • Q16: Will ORCA upgrade the magnetic powder cup?
  • A16: Will not. The magnetic cup will increase the cost, and It will be a disaster if you accidentally force touch it and falls off during grinding. The threaded cup is a more straightforward and lower-cost design, allowing us to avoid some of the most infuriating moments.
