An American-style Amber Ale, with maple sap and syrup. Maple sap is the clear liquid that maple syrup is made from. In this recipe, maple sap replaces your brewing liquor. Maple sap contains 2.5% sugar on average. (In contrast, maple syrup contains around 66% sugar.) If you don’t have access to maple sap, use water and add an extra 1.66 pints of maple syrup during the boil. The amount of German smoked malt called for will only yield the faintest whiff of smoke. For a stronger smoked flavor, try replacing it with some home-smoked malt (we’d try hickory smoke.
