The many trees you can tap for sap – and syrup

Syrup is usually associated with the sugar maple. The sugar maple and all species of maple can be tapped. Even more surprising is that many other trees can be tapped for sap, which can be turned into delicious syrup.

Sugar maple (Acer saccharum)
The sugar maple yields the highest volume and concentration of sap, making it a superior candidate for tapping. Its sugar content is approximately 2.0%.

Black maple (Acer nigrum)
Black maples produce as much sweet sap as sugar maples. The trees closely resemble sugar maples and can be distinguished by their leaves. Black maples tend to have leaves with three major lobes, while leaves from sugar maples have five lobes.

Red maple (Acer rubrum)
Sap yields from red maples are generally lower than those from sugar maples, although some tapping operations utilize only red maples. The trees bud out earlier in the spring, which may reduce syrup quality near the end of sugaring season.

Silver maple (Acer saccharinum)
Like red maples, silver maples bud out earlier in the spring and have a lower sugar content than sugar maples (1.7% compared to 2.0%).

Norway maple (Acer platanoides)
Native to Europe, Norway maples are now considered invasive throughout much of the United Sates. They are not as sweet as sugar maples, yet can be tapped regardless.

Bigleaf maple (Acer macrophyllum)
Bigleaf maple is the main species of maple growing between central California and British Columbia. Native Americans have tapped these trees for centuries, and although the sugar content and sap flow are less than those from sugar maples, these trees can still provide a commercially viable source of syrup for the Pacific Coast.

Canyon maple, big tooth maple (Acer grandidentatum)
These trees are found primarily throughout the Rocky Mountain states. They also grow in Texas, where they are referred to as Uvalde bigtooth maples. The sugar content is comparable to that of sugar maples, but the volume produced is much less.

Rocky Mountain maple (Acer glabrum)
Rocky Mountain maples are native to western North America, and have been used traditionally by various groups, including the Plateau Natives.

Butternut, white walnut (Juglans cinerea)
The butternut produces a sap that yields roughly 2% sugar – similar to sugar maples. The timing and total volume of sap are also comparable to sugar maples.

Black walnut (Juglans nigra)
The black walnut tree is a valuable timber species, whose sap flows in autumn, winter, and spring. It is more common in the Midwest than in the Northeastern United States.

Heartnut (Juglans ailantifolia)
A cultivar of Japanese walnuts, heartnuts have sugar contents comparable to sugar maples, but produce much less sap.

English walnut (Juglans regia)
These are the walnuts commonly eaten and purchased from supermarkets. They are not typically found in the Eastern United States, but rather are grown most abundantly in California. English walnut trees can be tapped successfully, especially when subjected to a freezing winter and spring.

Butternut, white walnut (Juglans cinerea)
The butternut produces a sap that yields roughly 2% sugar – similar to sugar maples. The timing and total volume of sap are also comparable to sugar maples.

English walnut (Juglans regia)
These are the walnuts commonly eaten and purchased from supermarkets. They are not typically found in the Eastern United States, but rather are grown most abundantly in California. English walnut trees can be tapped successfully, especially when subjected to a freezing winter and spring.

Black birch (Betula lenta)
Native to eastern North America, black birch is most popular for its use in making birch beer. And, as this list suggests, the black birch can be tapped.

River birch (Betula nigra)
Found growing abundantly in the southeastern United States, and planted as an ornamental in the Northeast, the river birch can successfully be tapped.

Gray birch (Betula populifolia)
Gray birch is more of a shrub than a tree, but may be tapped if it grows large enough.

European white birch (Betula pendula)
Native to Europe, and grown as an ornamental in urban and suburban areas of the United States, European white birch can be tapped.

Sycamore (Platanus occidentalis)
Native to North America, the sycamore tree has a lower sugar content than sugar maple, yet is reported to produce a syrup that exudes a butterscotch flavor.

Ironwood, hophornbeam (Ostry

a virginiana)
These trees produce a sap later in the spring, although the sugar content and volume are much less than those from birch trees.
