The taps have been in for two weeks, but hardly a drop of sap has been collected. As soon as we got everything ready for the first sap runs, spring reverted back into winter. Things look great for this week:
Ideal sap flow occurs when the day time and night time temperatures fluctuate around the freezing point. The change of pressure inside the tree due to the freezing/thawing causes the sap to flow. Hopefully the predictions will be accurate, providing strong early flows that typically produce light syrup, which is great for making maple cream.
