Sweet maples
While it is possible to identify sweet trees through sap testing, the reasons why certain trees are sweet may be mostly genetic, and finding those genes may be no easy matter.

Sycamore Sap and Syrup Field Trial
This study showed that sycamore does produce a sweet sap flow that can be boiled down to roduce a syrup. That syrup had a nice taste, that some people say has a butterscotch like flavor. This is a new sap and syrup product, that will need more work to develop taping strategies that could lead to its commercial production. Likewise we need more information on the sap and syrup chemistry before we can provide guidance to potential syrup producers.
Tap Below Lateral
How producers can effectively set taps below the lateral line.
Taphole Injury in Red Maple
Maple tapping guidelines, which specify the number of taps in relation to bole diameter, and the spacing and depth of tapholes, have been devised primarily using sugar maple wounding as a model. With its importance as a present and future resource for maple sap, it is critical that we extend our knowledge about taphole wounds to red maple so that, if necessary, these guidelines can be revised to include the proper and sustainable tapping of this species.
Taphole Staining and Sap Yields
The compartmentalization (walling off) process in maple trees and how it affects how to tap for maple syrup production.
Tapholes in Sugar Maples: What Happens in the Tree
Maple syrup production starts by drilling a taphole in the tree. This process injures the wood, which may become discolored or decayed as a result. If trees are to be tapped, every effort must be made to minimize injury while obtaining the desired amount of sap. Information about tapholes is given here for the benefit of the producer. Some important points discussed are: how trees compartmentalize discolored and decayed wood associated with tapholes, how some tapping procedures lead to cambial dieback around the hole, the problem of overtapping related to increased use of mechanical tappers, and new information on the use of para formaldehyde pills, which can lead to more decay in trees.
Tapholes: Straight or Slanted?
Is there any difference in sap yield when tapping at a slight angle (the historical recommendation) or tapping straight in (the current recommendation)? While there might be other considerations suggesting that tapping straight in is advantageous, from a syrup yield perspective, there is no apparent difference.
