How To Make Pure Maple Syrup

When to Harvest Maple Syrup

There are two very important factors that determine when you can harvest sap from maple trees.

1. Maturity of the Trees: The maple trees should be at least 8" in diameter in order to take sap from them. If the diameter is 20" or more, the tree can handle 2 spiles, one one each side of the trunk.

2. Time of Year (Maple Syrup Season): The time the sap starts running from maple trees is in the spring when it’s above 32ºF (0ºC) in the day and below 32ºF (0ºC) at night. This is the only time to harvest maple syrup each year. Stop harvesting the sap when you notice the leaf buds start to swell. The spiles can then be removed.

How Much Syrup Can You Expect?

Maple Sap (Water) Amount: The amount of sap you get from one tree is going to depend on each season and each tree. If it was a dry summer, you will get less sap the following spring.

Maple Syrup Amount: One 5 gallon pail is going to get you about 2 cups of maple syrup once it's cooked down. This is approximate and it's based on my own experience.

Our Best Year: In our best year yet, we collected 320 liters of sap, which resulted in 8 liters of syrup. This is what you can expect in a good year for a hobby farm like ours with about 20 trees.

Equipment and Supplies Needed:

Spiles (taps) with hooks:

Hose (drop line):

Mesh or Screening

Elastics

Note: There are different types of taps. One type is a spile with a hook attached to hang a pail (pictured). Another type is a spile that you slide a hose on to.

If using the spile with a hook, you need a mesh or screening and elastic to cover the pail to avoid debris and flies getting into the pail.

Drill with 7/16” Drill Bit, Hammer, Stock Pots, Pails & Lids

I use a 2.5 gallon pail to hang on the trees, 5 gallon when using a hose and then 5 gallon pails to collect the sap. You can also use purpose-built buckets for hanging.

Tip: You can usually get these pails from a restaurant or deli for a good deal. The 5 gallon ones are available at hardware stores or online.

Cheesecloth

Syrup Jars with Lids

Candy Thermometer

There are kits available as well that supply you with filters, spiles and drop lines.

Step #1. Drill a Hole

Drill a hole into a maple tree with a 7/16" bit, approximately 1.25" deep. When drilling, drill the hole slightly upward into the tree. Hammer the spile into the hole snugly.

Step #2. Set up the Pails

Whether you are using a hose or hanging a pail, I will show you both options because we do it both ways.

1) Use a Hose: Attach a hose to the spile that leads into pails on the ground.

Or...

2) Hang a Pail: Hang your pail directly onto the spile hook and secure it with wire so that it doesn't blow around or take off in the wind.

Step #3. Cover the Pails

Put some mesh screening over the top of the hanging pail and secure it with large elastics. This helps keep debris and bugs out.

If using the hose method, you can put the lid on the pail. Drill a hole into the pail lid and stick the hose into it.

Now you just wait and let the pails collect the sap as it drips out of the spiles.

PRO TIP: If using the pails with a lid, I drilled 2 holes into it so that I can place the hoses from 2 trees into it and still keep the pail covered.

Step #4. Check the Pails

Check the pails every day or every other day until they're full. It depends on how fast the maple water is running (during good years we could get up to a couple of inches in a day).

Maple water is simply the sap from the maple tree. It is formed when groundwater mixes with the sugar from the trees. It is approximately 98% water and 2% sugar.

Step #5. Collect the Water

Once you have enough maple water (the sap) in each pail, start collecting the maple water in separate pails. I fill 5 gallon pails. Return the pails to the trees for more maple water.

Step #6. Transfer to Pot

Remove the lid or mesh from the pail and place cheesecloth over top. Secure it with an elastic. Carefully pour the maple water through the cheesecloth into a large stock pot. (This will remove any debris that has found its way into the pail--I always end up with a little debris so this will make sure it doesn’t get into the pot.)

Step #7. Prepare the Heating Source

Now you will start getting ready to cook down the maple water. I use a wood furnace that we took out of our house. Start the fire and place the stock pot on top of the stove/grate.

PRO TIP: If you do not have an outdoor wood furnace like us, you can use a fire pit with a screen/grate on top for cooking (in order to place the stockpots on).

Step #8. Cook

Cover the pot with the lid as this will cut down the cooking time. You will need to keep the fire going for quite a while so make sure you have enough wood on hand. Keep cooking. No mixing is required.

Step #9. Transfer

Once the maple water boils down to approximately 1.5″ to 2“ deep in the pot, it is time to remove it from the outside fire. (This time will vary greatly but it takes me around 6 to 8 hours. Watch carefully because if you go over this, it can quickly burn and become black.) Bring it into the house.

Step #10. Strain

Place some cheesecloth in a mesh strainer and on top of a bowl or measuring cup. Pour the liquid through the strainer and let it settle. There will be sediment on the bottom. Again with a strainer and cheesecloth, slowly pour it into a large pot.

Step #11. Sterilize Jars

Have your bottles or jars and lids ready before the maple syrup is completely ready. Sterilize each jar and lid.

Step #12. Boil

Start boiling the sap again until it reaches the soft ball stage (235°F/112°C). Be careful, this can easily boil over so you need to watch it once it starts bubbling. Turn your stove down enough so that it keeps boiling but not rising over the pot. Once it gets to a soft ball stage, it is ready to put into syrup jars. You will notice the syrup getting thicker as you go.

Step #13. Pour into Jars

Carefully pour the syrup into your jars, wipe the edges clean and seal with the lids.

Storage

• My jars usually seal after I transfer the hot syrup to the jars and cover them with the lids. It's important that you wipe the rim of the jar clean before covering. Store sealed maple syrup in a cool, dark cupboard or in a cold storage for up to a year.
• Once opened, it can be stored in the refrigerator for up to one year or in the freezer indefinitely.
• Maple syrup can mold, and I know because I've experienced it myself, both with homemade and commercial syrups. If you see any mold, discard it.

Tips

• Hanging Method: If you are hanging a pail on the tree, I recommend using a 2.5 gallon pail so that it doesn't get too heavy as it fills up.
• Hose Method: If you are attaching a hose to a pail on the ground, I recommend 5 gallon pails.
• Boiling: I don’t recommend boiling down the sap inside the house as it will take a very long time and the steam can ruin your cupboards.
• Sterilizing the Jars: I usually use a sterilizing powder from a wine-making store, but you can use other options like the dishwasher or submerge them in boiling water for 10 minutes.
• How to Check for Soft Ball Stage Without Thermometer: If you don’t have a candy thermometer for this step, put cold water into a glass cup. Drop a few drops of the syrup into the cold water. If you can form a soft ball with the syrup using your fingers, it is ready.
• Drilling: The following year, you shouldn't drill a hole in the same spot. Drill a new hole elsewhere on the tree.
• Festivals: be sure to check out maple syrup festivals in your area!
