The Quick Sap to Syrup Ratio Answer

In general, the sap to syrup ration when boiling sap to make maple syrup is 40 to 1. You can expect an average of 1 gallon of maple syrup for every 40 gallons of sap.

This is an average and depends on the sugar content of the sap. Most time you will get somewhere between 60:1 and 20:1 (sap:syrup). Below we will go into more details of how to much syrup you will get from your maple trees as well as how much sap to expect from a maple tree.

We've been collecting sap and boiling it into maple syrup for over 10 years on our backyard farm in New Hampshire.  Over the years we've tried different equipment and perfected our system for making delicious syrup.  You can find more resources on our page to help you get started making your own syrup, but if you are brand new here, I recommend starting with our Complete Guide to Making Maple Syrup.

What Factors Contribute to the Sap to Syrup Ratio?

How much sap to make maple syrup depends on the sugar content of your sap.

The amount of sugar in your sap depends on several factors and changes based on yearly fluctuations, your location and even the specific tree. You have very little control over the amount of sugar you will start with in your sap. Below you can see some of the specific factors:

Maple Tree Species: This is the biggest factor for the amount of sugar you will start with in your sap. Sugar maple trees have the highest sugar content and are the prefered trees for making syrup. The sugar maple (Acer saccharum) ranges from 2% to 3% sugar content or even higher under ideal conditions. Other species, such as the red maple (Acer rubrum) and silver maple (Acer saccharinum), generally have lower sugar content in their sap.

Tree Health and Age: Healthy, mature trees are more likely to produce sap with higher sugar content. Young or stressed trees may have lower sugar concentrations in their sap. Even maple trees of the same age may produce sap with different sugar contents.

Environmental Conditions: Weather conditions play a significant role in the sugar content of maple sap. You will find sap flowing when nights are cold nights followed by warm, sunny days in late winter or early spring. These temperature fluctuations are essential for the sap to have higher sugar content. The freezing and thawing cycles cause changes in pressure within the tree, pushing sap out of the taps.

Time of Season: The sugar content of maple sap tends to increase as the sap flow season progresses. Early in the season, the sap may have lower sugar concentrations, but as the weeks go by, the sugar content typically rises. Sap collected later in the season is often sweeter.

Geographic Location: The geographical location of maple trees can also influence sugar content. Trees in some regions may produce sap with consistently higher sugar concentrations than those in other areas. This is related to overall climate conditions.

Using the Rule of 86

One of the easiest ways to determine how much syrup you will get from your sap is to use the Rule of 86. To use this role, you will need to test the sugar content of your sap. You can test the sugar content of the sap using a hyrdometer or refractometer.

Once you have the number, you divide 86 by the sugar content. This will give you the amount of syrup you can expect. So imagine that your sugar content is 2%. If you divide 86 by 2 you will get 43. This means you will need 43 gallons ot sap to make 1 gallon of syrup.

Other Questions about Making Maple Syrup

Below you can see a few of the other common questions we get asked about making maple syrup.

How much maple syrup per tree can you expect?

The exact amount of syrup (and sap) you will get from your tree depends on many things, including the size and age of your tree. A general rule is you can expect 10 to 20 gallons from a single sugar maple tree.

How much sugar in maple syrup?

The standard sugar content for pure maple syrup ranges from about 66% to 68%. In other words, approximately two-thirds of the total content of maple syrup is sugar, primarily in the form of sucrose.
