I wondered how maple syrup is made, so I looked to
TapMyTrees.com.
I
found out that sugar maples are the best trees to tap, but black, red, or
silver maples also work. The sap starts
to flow in February or March, and the best weather is alternating warm and
cold—it gets the sap flowing. Trees
should be 12” in diameter or more, and bigger trees can have multiple
taps. The sap typically flows for four
to six weeks, and tapping stops when the temperatures remain above freezing and
the leaves start to come out.
The basics are simple:
Drill a upwards-slanting hole 2 to 2.5 inches deep, then hammer in the metal
tap and hang a clean bucket from the hook on the tap. (The photo below uses a different kind of
taps.) Sap starts to flow immediately,
and it looks like water. It may drip
slowly, or it may fill a bucket in a day or two.
Then it’s just a matter of collecting the sap buckets,
filtering out the impurities, then boiling off the excess water, which turns
the maple sap into maple syrup. The
syrup is done when it’s thick and golden.
The sap-to-syrup ratio varies, depending on who you ask—some sources say
as little as 10-to-1, but most say much more.
Someone at our church makes a few gallons of maple syrup every year, and
he gave us a pint the other day. I asked
him how many gallons of sap it took to make a gallon of syrup, and he said it
took forty!
One caution—don’t try this in the kitchen! This warning comes from Rink Mann on
MotherEarthNews.com:
The main thing about
making maple syrup is you have to boil off about 32 quarts of water in the form
of steam to end up with one quart of maple syrup. That means that if you’re boiling down a batch
some Saturday afternoon on the kitchen stove and are aiming for three quarts of
syrup, you’re going to put about 24 gallons of water into the air before the
boiling’s done. Unless you’ve got one
powerful exhaust fan, you’ll end up with water streaming down the walls and
enough steam to impair visibility across the room. And, when things finally do clear, you’re apt
to find the wallpaper lying on the floor. Then, too, even if the batch doesn’t boil
over, which it can, the sugar spray from all that furious boiling gets all over
the stove and is harder than blazes to get off. So, if you want to maintain a measure of
domestic tranquility, it’s best to do your boiling outside, or in a handy
garage or shed.
Rink also has a great step-by-step guide to making maple
syrup in your own back yard (see the above link).
