Had a really good night last night. Lots of sap from the lower bush but very little from the upper bush where temps barely topped freezing. 150' of elevation change can sure make a difference!
Wild cold winds were roaring through the sugarhouse. Kept the cupola doors closed to try and stay warm. Despite having the feed line freeze up I was able to begin drawing syrup within 1/2 hour of startup and continue drawing without stop for the next 3 1/2 hours till I shut down at 11 PM. Didn't check sugar content, but must have been in the 2.5 to 3% range judging by the amount of syrup coming off.
