See It Made:

We place roughly 5,000 taps in nearly 3,000 maple trees each winter.  Each tap is connected to a system of tubing that runs into our sap house.  Once collected, the sap is processed in our reverse osmosis machine which removes about 75% of the water from the sap.  We then boil the concentrated sap in our sugarhouse evaporator until it reaches the right level of sugar content of pure maple syrup.
