When is it Syrup? Tools and techniques for measuring syrup density
One of the most important skills for sugarmakers to master is knowing when what’s boiling in the evaporator has become syrup. Quality control is key, and packaging syrup too dense or not dense enough will ruin the best of any sugarmaker’s efforts.
When is it Syrup? Tools and techniques for measuring syrup density
One of the most important skills for sugarmakers to master is knowing when what’s boiling in the evaporator has become syrup. This guide to mesuring density explains the tools and techniques for accurate measurement.
When to Add a Second Tap Under Vacuum? – Part 1
Determining the proper diameter at which to put a second tap in a maple tree can be difficult. The decision can be affected by numerous factors, including: tree diameter, tree growth rate, previous tapping history, whether vacuum is used and if so, what level, the additional yield of sap, and the cost/benefit ratio (factoring in both time and $), among others. These considerations have factored into the development and use of tapping guidelines. In some cases, guidelines were developed with science-based answers to some of these questions. In other cases, guidelines were more of a “rule-of-thumb”used by producers in broad regions. While tapping guidelines are mostly, as the name implies, non-regulatory suggestions, in other cases such as in organic production or when producers lease taps, neglecting to adhere to guidelines can have undesirable consequences such as revoked organic certification or losing the ability to access leased taps
When to Add a Second Tap Under Vacuum? – Part 2
In a previous article we reviewed previous work and described an approach to determine the amount of syrup gained by adding a second taphole to a tree (Perkins et. al. 2025). This study follows up on that work by determining yields from trees across a wide range of sizes with either a single, or two tapholes, over several seasons.
When to Stop: Some Factors Affecting The Economics of Processing Grade Syrup
Near the end of each sugaring season, producers must make a decision when to stop making maple syrup. Sometimes the decision is an easy call, such as when the onset of bud break and cessation of sap flow coincide. The decision to stop production can also be the result of careful economic analysis of the cost of production versus value of the product. The variable costs (fuel, labor, filters, etc.) of any maple operation are a key component to this sort of analysis.
When Tubing is Tapped Out: Recycling Maple Plastics
As the maple industry has grown, so too has the use of plastic sap tubing. Solutions are needed to help producers dispose of tubing when it is past its useful life, in ways that ensure it is not merely ending up in landfills.
Which side of the tree should you tap?
Thoughts and data on how setting taps on different aspects of a tree can impact sap yield.
Why and How to Check your Hydrometer’s Accuracy
Hydrometers are a critical tool for making high-quality, legal density maple syrup. A $20 to $30 investment in an accurate hydrometer can yield a valuable return in income for the producer. This article explains how to use and test a hydrometer for accuracy.
