 March begins. It's been really cold and maple producers are gearing up and will do their best to provide wonderful maple sugar production. Latest conditions will be given for many of the sites below and conditions vary from area to area.
Spring fever warms the air and also brings another kind of March madness. Before sugar maple buds open, the tree needs nutrients found in sap. Below-freezing nights and sunny, warm (40 degrees F) days provide optimal conditions for sap to start moving up the tree, possibly draining into a bucket or through a network of tubes to a sugarhouse, where it is evaporated over roaring fires and transformed into a regional delicacy sought round the world--Maple Sugar.
Begin your maple excursion with the annual Maple Weekend in New York, (March 16-17 & 23-24, 2013 10 a.m.-4 p.m.) sponsored
by the New
York State Maple Producers Association (a consortium of
550+ maple producers throughout
the state) in an area nearby. Maple sugar producers host special open houses to demonstrate the art
of making maple syrup. This site provides nice starting points
for learning more about the production of maple syrup: its history, the collecting,
the processing,
and a list of FAQs about maple sugaring and syrup production. Another great site to visit is from the University of Vermont. It offers a comprehensive collection of resources on the entire maple syrup industry and includes history, science, agriculture, and economic materials.
Sugar maple (Acer saccharum) is the most common maple species in New York. Maples provide the brilliant red autumn leaves, and in spring  further stimulate our senses with maple syrup derived from their sap. This leaves little wonder why the sugar maple is New York's official state tree and appears in the center of the Canadian flag.
What's News...
- New York's Maple Industry Has Untapped Resources. (Feb. 27, 2013 Democrat & Chronicle (Roch. N.Y.)). Article and video on the potential volume of maple sugar production by New Yorkers (food for thought).
- Maple-inspired music: View fiddler Ward Allen playing Maple Sugar, and then listen to the Maple Sugar Polka.
 Maple Sugaring Tour for UB Students. The University at Buffalo International Student and Scholar Services schedules trips throughout the year. The maple sugaring adventure is on March 23, 2013; 8:00 am to 2:00 pm. The trip is to a local sugarbush, to watch maple syrup being made, followed by pancakes with fresh syrup. - Maple Sugar Festival. Saturdays & Sundays, March 16-17 & 23-24. Genesee Country Village & Museum. Sugaring program 9:30 a.m.-4 p.m. /
Breakfast 9 a.m.- 1 p.m. "Celebrate this special time at the museum in March with a Pancake Breakfast, self-guided walks to the sugar bush, 19th-century and modern syrup-making demos and tastings.
The entire museum will be alive with activities—including hands-on crafts, games, food tastings, dancing, open-hearth cooking in our historic village, a maple cooking contest, a maple sugar history trail and even brewing up some maple beer.
Maple-sugaring activities including log hewing, spile carving, tree tapping, sap collection and boiling down the sap to syrup and sugar. Visit the cooper and tinsmith as they make buckets for collecting sap.

  Obtaining
the raw material for maple syrup results of physiological processes
that turn each tree into an osmotic pump. Steve Vogel ("Nature's Pumps" American Scientist 82,
September-October 1994) describes the movement of ions across cell
membranes allowing a concentration gradient to be maintained where, "a
mere one-molar concentration difference generates over one million pascals, so an osmotic pump can easily work against quite a high
resistance."
As the daytime temperature begins to rise, starch accumulated during the previous summer and stored over the winter in the tree's zylem parenchyma is hydrolyzed by special "contact cells." Hydrolyzed starch products include the sugar, sucrose, which can reach concentrations of 3-5%. The osmotic pump is "primed" with the high concentration of sugars dissolved in the maple tree's large plumbing network of phloem. Water drawn into the trees by its root system provides the sugary sap that can travel at the rate of 1m/hr. The maple tree is "tapped" to
capture the flow and provide the sap for maple syrup.
The sap obtained from the maple tree is a clear, colorless, sterile liquid providing the water and nutrients for the tree's buds. The North American Maple Syrup Producers Manual "Appendix 2: Chemistry and Quality"
provides a chemical analysis of sap: 98+% sucrose, < 2.0%
glucose, phenolic compounds, amines, peptides, amino acids, proteins,
and organic acids. It takes about 40 gallons of sap to produce one
gallon of maple syrup, which weighs about 11 pounds and has a 66.5% sugar content.
 Maple sugaring (producing syrup from sap) was shown to the first European settlers to the Americas by native Indian tribes and involves a variety of scientific and technical concepts: levers (splitting firewood), heat transfer, viscosity, boiling point, and depression of freezing points are among the concepts of physics involved in transforming the watery sap to a thick, rich, amber syrup. Larry R. Yoder's The Physics of
Maple Syrup Making
is a good starting point for learning the science behind the process.
