Guy I bought my used equipment from told me he used maple regularly in his brewing. He had maple trees on his property, which he tapped for sap. Told me he'd reduce 20 gallons of sap down to 5 gallons and use it in place of the water in the brown ale recipe from his local HBS - claims it was AWESOME. Now, if you can find out the normal reduction of sap to syrup, you can figure out how to reconstitute syrup into 5 gallons and replicate this guy's technique. I think for some reason that it takes 20 gallons of sap to make 1 gallon of syrup, but I'm not certain. If that's correct, though, you could buy 1 gallon of syrup and add 4 gallons of water to "get er done"...
