In recent years, someproducers have seen the benefit of tapping maples below the lateral line for multiple reasons. The main reason is to access a larger area of healthy wood on the trunk. This is because the maple tree produces a compartmentalization zone inside the trunk following tapping, which isolates the wound left by the tap hole.
By opting for a tapping pattern that respects the necessary spacing of taps from year to year based on their size and number, the likelihood of tapping into compartmentalized wood is minimized. If, in addition, the tapping area is expanded by allowing tapping below the lateral line, the exploitation of the trunk surface is further optimized, ensuring the sustainability of sap collection.
