I live near the New York and Pennsylvania border. I have two flow hives. I was able to extract honey this year from one of the hives. The other hive was weaker and did not produce enough honey for me to take. In the stronger hive, four of the six flow frames had honey that I could extract. It was October 5, 2016 when I extracted two frames at one time.
I have two brood boxes on the bottom, then queen excluder, then the flow hive on top of that. The two bottom brood boxes are being left untouched for overwintering.
The honey was typical of NY Autumn honey; very dark, flavorful, and molasses-like. It seemed to be thicker than normal to me, but its density was actually a seemingly fairly normal 1410 grams per liter. I was able to pull approximately two liters from each flow frame. I did time-lapse photography of the filling up of the glass containers. I left a clock and a thermometer in the image as the video was being made. Approximately 2 liters flowed out of each frame in about 3 hours. I pulled 4 liters total from those two frames. The outdoor air temperature was 70 degrees F (21C). The actual honey temperature was 77 degrees F (25C).
I intentionally left one flow frame in the flow hive super for now. I am waiting for the outdoor air temperature to drop significantly and hold there for a few days so that the honey also chills down. I doubt if anyone would ever be pulling honey in NY when the outdoor air temperature was much less than 40 degrees F (4C), but I am waiting for some temperatures down near there to see how long it will take to get the two liters of honey out of the one remaining flow frame. After I get that data, I will try to remember to re-post the information in here to update anyone who might be interested.
I could not find any good general viscosity data online for honey at temperatures that were below 68 degrees F (20 C). If anyone has that kind of data, could you please share it on here?
