What is it called when you make maple syrup?

The process of making maple syrup from maple tree sap is known as maple sugaring or maple syrup production. Some key questions about maple syrup production include:

How is Maple Syrup Made?

Maple syrup is made by collecting sap from sugar maple trees, then boiling it down to turn the watery sap into delicious syrup. Here’s an overview of the basic process:

1. Tap the Trees

The first step is tapping the sugar maple trees in late winter or early spring when daytime temperatures are above freezing and nighttime temperatures below freezing. A hole about 2-4 inches deep is drilled into the trunk of the tree. Then a metal spout called a spile is inserted into the hole to direct the sap out of the tree and into a bucket or tubing system.

2. Collect the Sap

Once tapped, the maple trees will start dripping sap – up to 10-20 gallons per tree. The sap is about 2% sugar water, with a slightly sweet taste. Collecting enough sap requires a large number of tapped maple trees and collection containers. The sap is gathered daily.

3. Boil the Sap

The watery sap needs to be concentrated into syrup. This is done by boiling it down in large, flat pans over a wood fire. As the sap boils, the water evaporates away leaving the sugar and other components behind. It takes about 40 gallons of sap to make 1 gallon of maple syrup.

4. Filter and Grade

Once boiled down to the target sugar concentration (66-67%), the maple syrup is filtered to remove any sediment or impurities. It is graded based on color and flavor – lighter syrup has a more delicate taste while darker syrup is richer. Common grades are Golden, Amber, Dark, and Very Dark.

When is Maple Syrup Season?

Maple syrup season takes place in late winter and early spring when conditions are right for sap flow. The season usually lasts 4-8 weeks, starting in late February or March and ending in April or early May. The timing depends on the weather in a given year and location.

Colder nighttime temperatures below freezing coupled with warm sunny days above freezing create pressure changes inside the maple trees, causing the sap to start flowing up from the roots. The sap flows best on days when the temperatures swing more extremely between night and day.

Where is Maple Syrup Produced?

Maple syrup production is concentrated in the northeastern United States and southeastern Canada where sugar maple trees grow. The species of maple matters – sugar maple is preferred, while red maple produces sap with lower sugar content. Other trees like walnut and birch can also be tapped for syrup.

The leading maple syrup producing states are Vermont, New York, Maine, Wisconsin, Michigan, Pennsylvania, New Hampshire, Ohio and Massachusetts. Canada is the world’s top producer, with about 70% of global supply.

How is Maple Syrup Used?

Maple syrup is commonly used as a pancake and waffle topping, added to oatmeal or yogurt, and used as an ingredient in baking, salad dressings, marinades and more. The flavor is sweet with notes of caramel and vanilla. Maple syrup grades affect the taste – lighter is more delicate, while darker is robust.

Maple syrup can be substituted 1:1 for white sugar, but it adds moisture so you may need to reduce other liquids slightly. It can replace up to half the sugar in baked goods recipes. Maple syrup is also delicious drizzled over ice cream, fresh fruit or roasted vegetables.

Maple Syrup Production Statistics

Year Total Maple Syrup Production (gallons)
2020 4,200,000
2019 3,900,000
2018 4,100,000

Maple syrup production varies year to year based on weather conditions during tapping season. In 2020, favorable weather helped yield 4.2 million gallons of syrup in the United States. Vermont is the top producing state, with over 2 million gallons annually.

History of Maple Sugaring

The practice of tapping maple trees for sap has been around for centuries. Native American tribes like the Algonquin and Iroquois were the first maple tappers, using sap as a sweetener and preservative. They carved v-shapes into tree trunks and let sap drip into birch bark buckets.

Early European settlers learned the art of maple sugaring from Native people. It became an annual tradition and backyard enterprise in the northern colonies. Innovations like metal spouts and buckets made collecting larger volumes of sap possible.

Maple sugaring was crucial for early frontier families. Syrup provided a badly needed sweetener and maple sugar could be stored or transported more easily than syrup. The maple spout became a common symbol of rural life.

In the 1900s, technological advances like plastic tubing systems, reverse osmosis machines, and vacuum pumps helped increase sap yields and efficiency. Modern maple operations use both old and new methods to produce maple syrup on a large scale.

Unique Aspects of Maple Syrup Production

Limited Season

Maple syrup can only be produced during the 4-8 week window when winter turns to spring. This short season and reliance on weather creates challenges for producers.

Labor Intensive

From tapping trees to collecting sap to boiling, filtering and bottling, maple syrup production requires significant hands-on labor. Automation helps, but much work is still done by hand.

weather dependence

Ideal conditions are needed for sap to run each season – freezing nights and warmer days with temperatures above freezing. Climate variability makes consistent yields difficult.

Mapped Trees

Producers tap the same trees year after year. Healthy mature maples with higher sugar content are selected and tracked to optimize sap yields.


Maple syrup production follows regulated standards on grading. Only 100% pure maple syrup can be labeled as such in the U.S. Artificial flavors are not permitted.

Modern Maple Syrup Production

While traditional methods are still used, maple syrup producers today have many technological advantages:

  • Tubing – A network of plastic tubes collects sap from multiple trees and transports it to a central collection tank.
  • Reverse osmosis – Removes some of the water from sap before boiling to increase efficiency.
  • Evaporators – Steam-heated pans rapidly boil and concentrate sap with precision.
  • Vacuum systems – Improve sap flow by equalizing pressure.
  • Bulk containers – Large stainless steel containers store syrup in bulk.

Technology allows maple operations to work on a larger scale. But personal monitoring, observation and adjustments are still crucial to make the best quality syrup.

Grades of Maple Syrup

Maple syrup is graded by color and flavor:

Grade A Light Amber

Delicate taste, light color

Grade A Medium Amber

Richer taste, darker color

Grade A Dark Amber

Robust taste, dark color

Grade A Very Dark Amber

Strongest taste, very dark color

Processing Grade

Used commercially instead of table syrup

Lighter syrup comes from sap tapped earlier in the season. Darker syrup comes from sap tapped later as temperatures increase. The grade selected is a matter of taste preference.

Fake or Artificial Maple Syrup

True maple syrup comes straight from maple sap and contains no artificial ingredients. Some cheap imitation syrups are made from corn syrup with artificial flavoring and coloring added. Read labels closely.

One sign of an artificial syrup is a very light color and weak flavor. Pure maple syrup gets darker and richer as more caramelization occurs during the boiling process. Maple-flavored syrup also lacks the nutrients found in real maple syrup.

Maple Syrup vs. Honey

Both maple syrup and honey are natural sweeteners with some similarities and differences:


Maple syrup comes from maple tree sap. Honey comes from flower nectar collected by bees.


Maple syrup production has a very short season. Honey can be produced year-round as long as bees have access to food.


Maple syrup has caramel and vanilla notes. Honey takes on the floral flavors of the nectar’s botanical sources.


Maple syrup has a smooth, pourable consistency. Honey can crystallize or turn solid over time.


Maple syrup has more than 20 minerals and antioxidants. Honey contains enzymes, amino acids and vitamins like riboflavin.

Both can be substituted for sugar, but honey is slightly sweeter so you may need less. Maple syrup works especially well in baking.

Maple Syrup Storage Tips

To retain the best flavor and quality:

  • Refrigerate after opening. Keep maple syrup chilled in the fridge.
  • Store in smaller containers to limit air exposure. Transfer to smaller jars.
  • Use within 1 year. Fresh syrup has better taste.
  • Check for signs like mold, crystals or bubbles which indicate spoilage.
  • Buy pure maple syrup. Look for words like “Grade A” or “100% pure”.

With proper storage, maple syrup can last over a year sealed and refrigerated. Commercial producers use preservatives and techniques like vacuum sealing to prolong shelf life.

Maple Syrup Production Process Summary

Maple sugaring involves multiple steps:

  1. Tap maple trees by drilling holes and inserting spouts.
  2. Hang buckets to collect dripping sap as temperatures fluctuate.
  3. Empty sap from buckets regularly and boil down over a heat source into syrup.
  4. Filter syrup through cloth or press filters to remove sediment.
  5. Grade and bottle the finished maple syrup while hot.
  6. Store in containers and refrigerate after opening.

It’s a traditional art passed down for generations. Taking maple sap to syrup is a sticky process but yields sweet, golden results loved by many.
