Birch syrup

Birch syrup is a savory mineral tasting syrup made from the sap of birch trees, and produced in much the same way as maple syrup. It is seldom used for pancake or waffle syrup, more often it is used as an ingredient paired with pork or salmon dishes in sauces, glazes, and dressings, and as a flavoring in ice cream, beer, wine, and soft drinks. It is condensed from the sap, which has about 0.5-2% percent sugar content, depending on the species of birch, location, weather, and season. The finished syrup is 66% sugar or more to be classified as a syrup. Birch sap sugar is about 42–54% fructose and 45% glucose, with a small amount of sucrose and trace amounts of galactose. The flavor of birch syrup has a distinctive and mineral-rich caramel-like taste that is not unlike molasses or balsamic condiment or some types of soy, with a hint of spiciness. Different types of birch will produce slightly different flavour profiles; some more copper, others with hints of wildflower honey. Many people remark that while Birch syrup has the same sugar content of maple it is far more savory than sweet.

Making birch syrup is more difficult than making maple syrup, requiring about 100-150 liters of sap to produce one liter of syrup (more than twice that needed for maple syrup). The tapping window for birch is generally shorter than for maple, primarily because birches live in more northerly climates. It also happens later in the year than maple tapping. The trees are tapped and their sap collected in the spring (generally mid- to late April, about two to three weeks before the leaves appear on the trees). The common belief is that while birches have a lower trunk and root pressure than maples, pipeline or tubing method of sap collection used in large maple sugaring operations is not as useful in birch sap collection. However Rocky Lake Birchworks in The Pas, Manitoba is successfully using the tubing method along with a vacuum system for collection of birch sap.
