The University of Vermont launched a new website last month for all things maple:
Maple Syrup
A quote from the website: "This website is a comprehensive subject guide in the field of maple syrup, touching on all aspects of maple syrup and sugar maples: maple syrup history, collection and production, marketing, nutrition and recipes, sugar maple cultivation, environmental issues and pests and diseases."
The website does seem comprehensive, but I did not find a recipe for Haymakers Tea (see the 7/24/09 issue of Agriview, p. 12). This maple drink has a number of names. When I was growing up, we called it switchel, and we did indeed drink lots of it when we were making hay. I think it would make a great sports drink!
UPDATE 4/09/10: Another good maple reference is the North American Maple Syrup Producers Manual published by Ohio State University Extension. One of the editors of this 329-page publication is UVM's Tim Perkins.
UPDATE 4/25/10: About 70% of the world's maple syrup is produced in Quebec. Maple syrup production in Quebec is controlled by quotas under the direction of the Federation of Quebec Maple Syrup Producers. Statistics on Canadian maple syrup production are available at Statistics Canada. Statistics on U.S. production are available from the NASS.
