Re: maple tapping
- Hello All,
As a recently subscribed member I am enjoying the various discussion
threads on this list. Two of these threads on which I wish to comment:
Many years since I attempted to boil down Acer macrophyllum sap
(Bigleaf or "Oregon" maple), but I recall that it took around 30%
more cooking time to produce a stable sugary syrup (i.e., beyond the
point of being likely to ferment) than it does with Acer saccharum
(Sugar maple). Therefore, one would want to consider whether using
A.macrophyllum warrants the amount of fuel involved.

seawater security wall around this site, and the resultant havoc, can
be regarded as a justifiable trade-off for the nuclear power that it
may yield. (And this is just one of dozens of such seacoast nuclear
sites in India and elsewhere.)
Isn't it ironic that the it took the unharnessed geophysical power of
the tsunami to reveal the design flaw in the nuclear power plant?
Rather, we could be tapping the immense power in ocean waves, tides,
and thermal differentials as humanity's primary electrical (and
hydrogen-fuel) power source, instead of the endlessly toxic and
archaic sources of oil, gas and nuclear energies.

There's no denying that Bigleaf Maple sap has less sugar in it, on
average, than does Sugar Maple sap, but the concentrations are
By one account (http://www.island.net/~maple/), the Bigleaf Maple
averages 2% sugar, while the Sugar Maple averages a little under 3% .
This might seem like a lot if one looks at it as the the Bigleaf
having roughly 30% less sugar compared to the Sugar (or the Sugar
having nearly 50% more, compared to the Bigleaf). Taking a broader
view, though, the concentrations are most near to each other within
the same order of magnitude; the Bigleaf's sugar concentration is just
about on par with that of other eastern maples which are tapped back
there besides the more favoured Sugar Maple; and there is even some
overlap, with sweeter samples of Bigleaf Maple sap outdoing weaker
samples of Sugar Maple sap.
So the two species are in the same league, even though the Sugar Maple
is at the top of the standings and the Bigleaf Maple is somewhere in
the middle. It's not as though it took 10 times as much fuel to boil
down Bigleaf Maple sap, or even twice as much. Given that, and given
that the Bigleaf is the one we have on hand here in the west, I don't
think the fuel needs really make a problem.
I don't say much here, but I thought this might be useful to
someone. You can concentrate the sugars not only by evaporation,
which requires a lot of fuel, but also by freezing. If you have a
freezer that you use all the time anyway, you might like to try it.
Here is an article from Mother Earth News that tells how:
- Hi again!
Just a couple more links and ideas.
Also try going to http://www.motherearthnews.com/index.php?
page=archindex and typing "maple" or "syrup" or "sugar" into the
search box at top right (not on the left - that's the book search).
I thought I read about a solar evaporator someone used to make
molasses, but can't seem to find it. What about using the parabolic
solar mechanism (usually used to make a solar stove) to concentrate
heat and boil the syrup? With molasses-making, they use several
metal trays in a line, evaporating the water out more in each tray,
and sometimes maple syrup is made the same way. One could use a
parabolic setup to heat each tray and perhaps speed the operation.
There are many places on the internet to get clear instructions on
making these parabolic setups at home, using cheap and available
materials. I like http://solarcooking.org/ - under "Plans", click
on "Parabolic Cookers".
