Weighing pros, cons of producing birch syrup

Michael Farrell |

Although many sugarmakers have heard that you can tap birch trees, very few of us have actually tried to produce birch syrup, and folks who have boiled down some birch sap have mostly had negative experiences. The sugar content of birch is much lower than maple sap (usually between .5-1 brix), so it takes a very long time to boil it down, especially when it’s done on a small scale without efficient processing technologies.

Prior to 2005 there was no research supporting any of the guidelines in use. However, maple producers need to pay careful attention to the caveats mentioned in the article MORE ]

Estimating taps per acre using the angle gauge

Stephen Childs, Cornell University |

Maple producers may wish to estimate the potential number of taps per acre to assess the productive capacity of an area, and to aid in estimating the costs for installing tubing systems or buckets. Once you know the number of taps per acre, you can compare sites and estimate costs using the tapping and tubing cost estimator. MORE ]
