If you make with maple syrup instead of honey, it isn't mead. Doesn't mean it can't be good. If he can get ahold of it, I'd recommend he uses a Grade B or C syrup. The grading system was put in place when maple syrup was used mainly as a cooking sweetner, so the LESS flavor the syrup has the higher the grade. Vermonters defend this system by calling the lack of flavor "delicate". I used to date one. "You can tell a Vermonter, but you can't tell them much."
Remember one unassailable statistic, as explained by the late, great George Carlin: "Just think of how stupid the average person is, and then realize half of them are even stupider!"
