Here's the big idea - tap the neighbor's massive maple tree and harvest the sap. Then use the sap INSTEAD of water to make beer. The beer needs to be a slight thing to get some of the maple character to come through. Soooo how about a cream ale? I used Pearle hops and an all-grain recipe with all malt rather than using corn or rice adjuncts.
When you make beer with maple sap, you don't get pancake maple syrup, instead you get a slightly woody spicy character. So this beer was a success and failure. We did get some extra alcohol from the maple sap, but the taste was not what people expected.
