Would you share your recipe? I tried to make maple wine from maple syrup this spring and it came out almost tasteless. It's good to blend with other, sharper wines I've made, but not to drink on its own. I'd love to make a good maple wine.
You should be able to swap maple syrup for honey in mead recipes. I'd use grade B or C if available. At least use the darkest you can find.
I used to live in north central PA. During the spring you could buy fresh maple syrup all over the place for about $45 / gallon. That's enough to do a 5 gallon batch at 12% alcohol.
I miss living there. Off the top of my head I can think of 3 orchards and 4 sugar shacks within 20 miles of my house. And about 20 places where they'd let you pcik all the apples off their trees for the asking. Seriously 20. <sighs>
I made maple sap wine 2 years ago that came out excellent. Jack Keller's recipe. It didn't taste anything like maple syrup, rather a spiced wine. If I recall, it took cloves and lemon zest. I wanted to make it again last spring but couldn't get any sap - it was a bad spring for the maple sugar makers around here.
