Testing the viscosity of honey?

It depends on the viscosity of your honey, many honeys are too high viscosity for a typical Zahn test.

average honey has a viscosity of about 2000 centistokes and the biggest zahn cup, number 5 goes up to 1800 centistokes @ 80 seconds, if you buy cup number 5, you may find a few will go through it, so you have to find a higher viscosity method.

quote: When measured at 25 deg C viscosity of honey samples came within the range from 18169 to 2560 cP

there are lists of viscosity tests like dropping a sphere of a specific weight & density and see the time it takes the sphere to reach designated junctures or something.
