My guess was that each tap might produce one liter of sap by the end of the day. That was supposed to be a conservative estimate, I have seen trees smaller than these overflow their buckets on a day with similar temperatures. Admittedly, I was pretty excited to drink some sap straight out of a bucket in January.
By the end of the day the temperature went back down below freezing and I checked my nine buckets. Not a drop in any of them. Boo. I have a few ideas about why there wasn't any sap flowing;
- It was pretty cold the night before, so it might not have been warm enough for long enough to thaw out the trees and get the sap flowing.
- It was overcast. Sunlight would have warmed up the trees faster than cool air.
- There was a chilly breeze. I don't know if trees feel the effect of wind chill, but that gusting wind wasn't helping anything.
- January might just be too early to be making maple syrup.
While I was disappointed that I didn't get to drink any fresh sap, I am satisfied with my little experiment. I know not to get to excited when the weatherman announces one warm day in a mostly cold month. And when the warmer days do show up my front yard will be ready to go!
