Maple syrup dominates when it comes to pancake toppings, but the sap of other trees like birch and walnut can also be tapped. New Leaf Tree Syrups, a brand under the company the Forest Farmers, located in Mount Lyon, N.Y., and Marshfield, Vt., now bottles woodsy, organic American beech syrup; viscous and fruity sweet birch syrup; thick, tart and tangy birch; earthy maple-walnut; and light, nutty maple-birch. The syrups come from trees in upstate New York and Vermont. Michael Farrell, a founder who runs the company and started an organization called Forest Farmers, was the director of Cornell University’s Uihlein Maple Research Forest.

New Leaf Tree Syrups, in 375 milliliter (12.7 ounce) bottles, $15 to $36, newleaftreesyrups.com.
