What is the evaporation process used in making maple syrup?

The evaporation process in making maple syrup involves collecting sap from sugar maple trees and then heating it to remove excess water. The sap, which is mostly water, is boiled down in large evaporators until it reaches a specific sugar concentration, typically around 66-67%. This process requires careful monitoring to prevent burning and achieve the desired flavor and consistency. Once the syrup reaches the right density, it is filtered and bottled for consumption.
