Why is maples syrup different colors?
Pure maple syrup ranges in color
from light golden amber to dark reddish-brown.
Over the course of the maple production season,
the color of maple syrup produced
in an individual maple operation
will gradually progress from lighter to darker.
This progression has many causes,
but is primarily due to gradual changes
in the composition of the maple sap.
The changes occur as a result of warming temperatures
and the production of accompanying metabolic changes
in the trees.
Many people feel like dark syrup is thicker,
but by law, they all need to be the same density.
