While drinking tree sap does not immediately sound appealing, Canadian producers are hoping that it will be the next must-try soft drink around the world. We have all heard of maple syrup, which is made by boiling down the sap of maple trees to produce a thick, sweet, golden-to-brown coloured syrup that is typically poured over pancakes. What is far less well known is that you can drink the sap itself, which is called maple water. Clear in colour, it contains just 2% natural sugars, so it is only slightly sweet. A small but growing number of producers in Canada are now selling this maple water in bottles or cartons, after first giving it a filter and pasteurisation to kill off any microbes. Advocates point to the fact it is a natural drink, and makers hope that it can steal some sales from the existing similar product – coconut water. The latter is made from water that naturally forms inside coconuts. As Canada is far and away the world's largest producer of maple syrup – accounting for more than 80% of production – it is understandable that the nascent maple water sector is also Canadian. For the maple water industry as a whole, one recent report predicts big growth. It estimated that global sales in 2024 totalled $506m (£409m).
