In the cold climates of North America, maple trees store starch in their trunks and roots as a way to conserve energy for the long, harsh winter. This stored energy transforms into sugar and sap as spring approaches.

When the seasons shift from winter to spring, locals collect this maple sap. The process involves drilling small holes into the tree trunks and gathering the sap as it flows out. The sap is then heated to evaporate the water, leaving behind concentrated maple syrup. Remarkably, it takes around 30 to 50 liters of sap to produce just 1 liter of syrup—a truly astonishing figure!
