How much syrup do you get from 5 gallons of sap?

Making maple syrup from maple sap is a delicious springtime tradition in many parts of North America. As the weather begins to warm in late winter and early spring, maple sap starts to flow through sugar maple trees. By tapping into maples trees and collecting this sap, it can be boiled down into sweet, golden syrup. But how much maple syrup can you expect to get from the sap you collect? Let’s take a closer look at the maple syrup making process to find out.

How Maple Syrup Is Made

The production of maple syrup begins by tapping sugar maple trees in late winter or early spring. A tap, which is a small hollow tube, is inserted into the tree trunk. The tap allows maple sap to drip out of the tree and into a collection bucket. An average maple tree will yield 10-20 gallons of maple sap per season. Maple sap looks like plain water but contains about 2% sugar content.

Once collected, the maple sap is boiled down. As the water evaporates away, the sugar becomes concentrated. It takes around 40 gallons of sap to produce 1 gallon of maple syrup. The exact ratio can vary depending on the sugar content of the sap. When the sap has boiled down to a sugar content of 66%, it becomes maple syrup. The syrup is filtered to remove any sediment and graded based on color and flavor. Darker syrups have a more intense maple flavor.

Factors That Affect Syrup Yield

Several factors impact how much syrup you can produce from collected maple sap:

  • Sugar content – Higher natural sugar content in the sap means more syrup yield.
  • Tree health and age – Older, healthy trees tend to produce more sap.
  • Weather – Colder nights and warmer days create better sap flow.
  • Regional climate – Colder regions have higher sugar content in sap.
  • Time of season – Early season sap has less sugar than late season.

Skilled maple syrup produces monitor these conditions to maximize their yields.

How Much Syrup Can You Get from 5 Gallons of Sap?

Now let’s look specifically at how much maple syrup you can expect from 5 gallons of collected maple sap.

As we learned above, it takes an average of 40 gallons of maple sap to produce 1 gallon of maple syrup. This equates to a ratio of 40:1.

We can set up a simple ratio calculation:

  • 40 gallons of sap = 1 gallon of syrup
  • X gallons of sap = Y gallons of syrup

With 5 gallons of sap, the calculation would be:

  • 40:1
  • 5:Y
  • Y = 5/40 = 0.125 gallons

So if you collected 5 gallons of maple sap, you could expect to produce approximately 0.125 gallons of maple syrup once boiled down, which is about 1 cup or 8 fluid ounces.

This will vary slightly based on the actual sugar content of your sap. But in general, 5 gallons of maple sap will yield about 1 cup/8oz of delicious maple syrup.

How Many Maple Trees Would You Need to Tap for 5 Gallons of Sap?

To produce 5 gallons of maple sap, you’ll need access to a number of actively producing maple trees. As mentioned earlier, a maple tree yields an average of 10-20 gallons of sap per season.

If we assume an average of 15 gallons of sap per tree, here is how many trees you would need to tap to yield 5 gallons:

  • 15 gallons per tree average sap yield
  • 5 gallons needed
  • 5/15 = 0.33 trees

Obviously tapping a third of a tree is not possible. Since you need a whole number of trees, you would have to round up. So to collect 5 gallons of sap, you need to tap at least 1 maple tree.

However, tapping just one tree may not guarantee 5 full gallons of sap. Given variability in individual trees, it is better to tap multiple trees to increase your overall sap yield.

Here is how many maple trees you should tap to reliably produce 5 gallons of sap:

  • Average 15 gallons sap per tree
  • Target of 5 gallons sap
  • 5/15 = 0.33 trees
  • Round up to 2-3 trees to account for variability

Tapping 2-3 maple trees will help ensure you can gather 5 gallons of sap to boil down into your 1 cup of maple syrup.

How Much Fuel Does It Take to Boil Down 5 Gallons of Sap?

Boiling down sap into syrup takes a lot of energy. It can be done on a kitchen stove top, but it takes a long time. Commercial operations use reverse osmosis, pre-heating, and large boilers to speed up evaporation.

For home tapping, it typically takes about 1.5-2 hours of active boiling over heat to evaporate 1 gallon of water out of maple sap. So how long does it take to boil down 5 gallons?

  • 5 gallons of sap
  • Yields about 0.125 gallons syrup
  • So 4.875 gallons of water needs to evaporate
  • At 1.5 hours per gallon, that’s 4.875 * 1.5 = 7.3 hours

It will take around 7-8 hours of active boiling to evaporate the excess water from 5 gallons of maple sap. This fuel needed will depend on your heating source:

If using an electric stove:

  • Electric range burner: 2,500 watts on high
  • 7 hours boiling at 2,500 watts = 17,500 watt hours
  • 17.5 kWh electricity required

If using a propane burner:

  • Outdoor propane burner: about 37,500 BTU/hour
  • 7 hours boiling at 37,500 BTU/hour = 262,500 BTU
  • Equals about 21 lbs of propane

So you’ll need around 17.5 kWh of electricity or 21 lbs of propane fuel to produce your 1 cup of maple syrup from 5 gallons of sap.

Cost Analysis of Making Syrup from 5 Gallons of Sap

Beyond time and fuel, let’s look at the potential cost of making maple syrup from 5 gallons of collected sap:


  • Taps & buckets: $20-$50 one-time investment
  • Filtering supplies: $10
  • Bottles or jugs: $10-$20
  • Stove or burner: $50-$200 one-time investment if needed


  • Electricity: $2-$3 at average rate of $0.15/kWh
  • Propane: $10-$15 for 20 lbs


  • Tapping trees: 1 hour
  • Collecting sap: 1 hour
  • Boiling sap: 7 hours
  • Filtering & bottling: 1 hour
  • Total: 10 person-hours

At minimum wage of $10/hour, the labor cost would be around $100.

So the total cost to produce 1 cup maple syrup from 5 gallons of sap could range from **$125-$250**. But the majority of costs are one-time equipment purchases that can be spread across many seasons of syrup production.

Increasing Your Maple Syrup Yields

Here are some tips to get the maximum maple syrup production from your tapped trees:

  • Tap high-yielding mature maple trees that are at least 10 inches diameter.
  • Tap trees on sunny south or east facing slopes.
  • Tap your trees early in the maple sugaring season.
  • Use sanitized spouts and collection buckets.
  • Keep sap cool after collecting to prevent spoiling.
  • Consider using reverse osmosis to pre-concentrate sap before boiling.
  • Use flat pans or narrow evaporator pans to speed up boiling time.
  • Filter syrup through tight filter to get clear, high-quality syrup.

Selling Your Maple Syrup

Once you have produced your maple syrup, you may consider selling it. Here are some tips:

  • Ensure your syrup meets grade A standards for flavor and clarity.
  • Bottle in attractive 500mL, 250mL or 100mL containers.
  • Design and affix appealing labels.
  • Sell at local farmers markets, craft fairs and stores.
  • Offer tasting samples to customers.
  • Explore e-commerce or online sales.
  • Price competitively based on your local market.

High quality artisanal maple syrup can often fetch premium pricing, especially if sold directly to end consumers.


Tapping maple trees and boiling down the sap into syrup is a time-honored tradition. While it takes effort, the sweet reward of homemade maple syrup makes it worthwhile. To produce 1 cup of syrup, you’ll need around 5 gallons of sap collected from 2-3 tapped maple trees. It takes 7-8 hours of active boiling to evaporate the excess water, requiring electricity or propane for fuel. Startup costs for equipment can run $125-$250, but these can be spread across many seasons. Employing best practices for tree selection, sap collection, and boiling will maximize your maple syrup yields from the sap you collect.
