One of our four properties ran a little harder than the others last night! Of course it’s the only one without a webcam on it. The sap is starting to turn blue and the syrup is foaming hard, the end is near…
Hiw come the sap turns blue?
Pure water naturally has a slight blue tint to it, but I believe this is due to the immediate deterioration of sap once it leaves the tree. Inside the tree the sap is completely sterile, but as it is exposed to the environment natural bacteria and yeast starts to consume it, often changing the colors. No worries though this sap made excellent syrup!
