In the woods

Three calculators for what a bush makes, and what your tanks and lines hold.

The In the woods chapter

What a bush should make#

A season's sap and syrup for a whole woods. Type the taps, the sap per tap for a season, and the Brix.

The What a bush should make calculator

Sap per tap is a season, not a day: roughly 10 gallons on gravity and 20 or more on good vacuum. Below the season, type an average day per tap to see what a run brings in.

What a tank holds#

How much a tank or a trough holds, square or round. Pick the shape and measure the inside.

The What a tank holds calculator

Use the depth you fill to, not the height of the wall: the last two inches of a tank are freeboard, not sap.

What a line is holding#

The sap standing in a full pipe, such as a sap pump-out line, that has not reached the tank yet. Pick the line size and type the length of the run.

The What a line is holding calculator

The size on the coil is the bore the sap runs in. It is what you lose at a freeze, or what an air purge pushes out.

FAQs

The Area tool in Map My Woods asks the same question: 50 is conservative, 70 a good stand, 100 optimistic. Count the trees in a circle if you are not sure.
