I've made many a gallon of maple syrup and I have to agree with Nate. 219 (corrected for barometric pressure) says it's done. Sap pretty much starts at 212, which, contrary to the OP is where water boils. I expect cider boils higher than that, but way under 219. Has the OP ever heard of a candy thermometer?
