sap has been collected from a sugar bush, it is transported to the
sugar house and boiled down to create maple syrup. A sugar house contains
a storage tank, an evaporator, and a fuel supply.
Fresh sap contains
approximately 1-6% sugar, while maple syrup contains about 66-67%.
To increase the sugar concentration of sap - and create syrup - many
gallons of water need to be removed from the sap. The evaporator is
the device that heats the sap and boils off this excess water. Did
you know that to produce one gallon of syrup, producers have to boil
off 32 to 40 gallons of water?
The storage tanks houses
the sap until the producer is ready to use it, and the fuel supply
- oil, wood, electricity, or natural gas - provides the heat source
for the evaporator. Most
sugar houses also contain facilities to store and package their syrup
or produce other products such as maple sugar. Many producers give
tours or market their products in their sugar houses.
