Birch water tastes like a super fresh and delicious glass of crystal clear water with only a rare hint of sweet if you look for it. When the sap is running, the tree is actually pulling the sap from its roots all the way up to the top of the tree to feed its leaf buds which is an amazing anti-gravitational feat in itself. Birch water goes bad within a couple of days, even in the fridge, so it needs to be consumed fresh. Alternatively, you can freeze it (even in ice cube trays) and save some frozen birch water to consume later in the year.
The tapping of one tree will produce a lot of birch water, so be careful not to tap more than you can consume. Very few of us will boil down the sap we collect to make birch syrup. We leave that to Sylvia Frisch and Berwyn Larson and their crew who are currently very busy, working around the clock, collecting sap from about 1500 trees and preparing Uncle Berwyn’s Yukon Birch Syrup to supply us all with the sweet stuff for the upcoming year.
My birch syrup supply is down to the last cupful. We are consuming about 1 litre of birch syrup per week! So I decided to boil down some sap and see if I could supplement our supply until the end of syrup season when we can get our next 12 L bucket from Sylvia and Berwyn’s birch camp. Birch syrup and maple syrup, although both sweet, are quite different in both taste and components.
Birch syrup contains fructose, the sugar in fruit, and it does not crystallize like maple syrup does. Maple syrup contains sucrose, the sugar in table sugar. One of the major differences between the two is the sugar content of the sap. It takes twice as much birch sap to make a litre of birch syrup, compared to making maple syrup. In fact the ration of birch sap to syrup is an astounding 80:1! What does that look like in real life? I took my two largest pots and boiled down 14 litres of birch water. All that sap produced a scant ¾ cup of syrup!
A big thank you to the birch trees for sharing some your sap and to Sylvia Frisch and Berwyn Larson and crew for all the hard work that goes into turning it into syrup! If you haven’t yet tasted birch syrup, you really must. It is delicious! When using birch syrup in recipes, I find I don’t miss the absence of other spices such as cinnamon or allspice.
