Making Maple Syrup: Tapping, Processing, & Canning

Have you ever wanted to make maple syrup but don’t know where to begin? We were in that same position several years ago. We knew syrup was pricey but we had maple trees on the property. While it seemed daunting at first, the process of making syrup is actually quite simple. It just takes time and a few supplies.

Today, I am hoping to give you a brief overview of how to make maple syrup, or, as it’s often called, “sugaring.” It takes a bit to fall into a rhythm that fits with the rest of your life schedule, but the sticky, sweet, delicious results are well worth the effort.

Making Maple Syrup(Color and flavor variation in homemade syrup is quite normal! We actually prefer the darker, stronger stuff.)

First thing’s first: identify the sugar maples on your property. Next, you can read my beginner’s checklist for making maple syrup to see what supplies, if any, you might need to purchase for the job.

Step one: Tapping

First, you have to access all that delicious sap. You’ll need spiles, tubing, and a corresponding wood drill bit. The spile is what goes into the tree, and the tubing is what carries the sap down to the bucket.

You want a drill bit that’s just slightly smaller than the spile is at its wide point, so that the spile fits snugly into the tree. Measure accordingly. (Ours was 5/8″.) Drill your hole & insert your spile, perhaps with a little gentle tapping to help it fit securely. Disclaimer: my hubby always does this part each year, so you’ll have to direct any questions about it to him. 😉March 2015 060

Here’s our spile sitting snugly in our maple tree.

This whole set up is referred to as a “tap.” Small trees should only have one tap, larger ones may have two or three.

Step Two: Collecting

You can use any number of different collection containers. Last year, we used well-washed milk jugs, and this year, we switched to plastic five-gallon buckets with lids so we wouldn’t have so much overflow. Whatever container you use, make sure the sap will flow into it without spillage. We use inexpensive tubing to channel the sap from spile to bucket. Some spiles have hooks to hang the bucket on directly so you don’t need the tubing. You can get a starter spile and tubing set here.

Here’s what our current set-up looks like:

March 2015 069Two taps headed to one bucket for easier collection. If you have enough tubing, you can connect multiple trees this way. (Note also this bucket is on the ground, so we avoid nailing into the tree.)


Step Three: Boiling

Each day, we go collect whatever sap is in the buckets and bring it up to the house for boiling down into syrup. We have a couple of different methods for doing this:

1) Crock pots- While crock pots don’t boil the sap very efficiently, they DO allow you to begin cooking the sap without needing to watch it carefully. We put a couple of large crock pots on our porch (without the lids) to begin slowly cooking the sap. This is also a good holding place for the sap until we can get to boiling it down further.

2) Indoor boiling- Definitely not the preferred method. Last year we boiled most of our sap in a roasting pan over two burners. It turns your house into a rainforest. The walls don’t like that much moisture, nor does the furniture. But if you don’t have any other options, it will do- just open the windows, turn on the fans, and hope for the best. 🙂 (Note: we DO bring our sap indoors to finish it when it’s close to the end. I just don’t recommend doing it for hours on end for weeks at a time.)

3) Wood stove boiling- The second year we made maple syrup, my husband put together a makeshift evaporator from an old, rusty wood stove, a bit of chimney, and a big tin can for a cap. We purchased two large steam pans to place directly on top of the stove to hold the syrup. This was MUCH better than indoor boiling, but still not extremely efficient.

4) Cinder block evaporator- This is by far the best method we’ve used so far. My husband made a simple rectangle out of cinder blocks on our driveway, built a fire inside of it, and hung our steam trays on the edges so they are directly over the flames. We’ve been able to boil down 25 gallons of sap in an afternoon this way- not too bad for not having a real evaporator!

Here’s the set up- my hubby builds a fire underneath, then closes the two front cinder blocks.

Whatever your method, you’ve got to boil the sap down til it develops a golden/amber color and gets nice and bubbly. We usually bring it inside for finishing on the stove top at this point. We make sure to filter out any bugs or dirt that may have been in the sap as we pour it into the pot inside.

This stage is when you really need to watch the sap. It will boil over on you if you’re not careful! If the bubbles keep trying to escape from the pot, throw in a pat of butter. It will keep it from the party to a reasonable level of wild.

Start checking the temperature with a candy thermometer frequently. It must reach 219 F, or 7 degrees above boiling if you live at high altitudes. Once it is 219, it’s done! (It might not look very syrupy right now, but it will thicken some as it cools.)

What happens if you overcook your maple syrup? You get maple candy. Or taffy. Or sugar. Or burnt blackness. It’s worth paying attention at the end to make sure you get what you looking for!

Step four: Canning

The nicest part of maple syrup canning is that you don’t have to process the jars in a water bath canner at all. Phew, one less step! When your maple syrup is getting towards the end, sanitize your canning jars, lids, and rings. To sanitize, put the clean jars in your oven at 200 F for 20 mins, and put the lids and rings in very hot/simmering water for the same time.

Once the syrup reaches 219, take it off the heat. Filter the syrup again as you ladle it into the hot and sterilized jars, leaving 1/4″ head space at the top. Place lids and rings securely, and turn your jars upside down for 30 seconds to make sure the lid is quite hot. Turn right side up and let cool. The jars will seal themselves without processing! Thanks to my awesome master food preserver cousin for confirming this miracle for me.

Step Five: Eat it.

Admittedly, the easiest step. Maple sugaring is a lot of work, but it’s such a fun project! It’s less expensive than purchasing real maple syrup, and MUCH tastier and healthier than the corn syrup “maple” flavored products in the store.

If you’ve got maple trees, give maple sugaring a shot! Let me know if you have any questions along the way- we are still learning each year we do it, but we’ll do our best to answer!

    How much syrup, on average, do you get each year? I would love to do this one day. We live in FL though and Maple trees don;t really do well here, lol.

      Last year, we had 16 taps and got over 4 gallons of syrup during the season. (We might have had more, but accidentally burned a couple batches!) It’s definitely enough to keep our family in syrup all year, plus some to give away too. If you ever move north you’ll have to try it! 🙂

    This is my second year in making my own maple syrup. Last year sap was given to me and my finished product was great. This year I’m tapping trees myself and have run into a couple of issues. First is my sap this year is much lighter than last years. Unfortunately I do not know for certain what kind of maples I’m tapping. Best guess is silver maple and possibly box elder. Don’t know if maple type has an effect on color. Second issue is my syrup is crystalizing in my jars. I’m canning right away after final boil while syrup is still hot. Jars are sealing nicely. Just looking for any answers or help. Thank you in advance and I look forward to hearing from you.

      Hi Dan! It’s great that you’re trying to tap yourself this year! We are just backyard tappers so perhaps a commercial sugarer could answer you more thoroughly, but here are my best answers from our experience and research.

      1. The type of maple does affect what kind of syrup you will end up with, because different trees have different sugar content. However, silver and box elder maples are still common trees that can be tapped for syrup. While it’s hard to perfectly ID trees in the winter, try checking them out when the leaves start coming out. That way you will know for next year exactly what kinds of trees you have.
      2. We talked to some folks at a local sugar shack, and they told us that the color of the syrup is largely due to what kinds of natural (unharmful) bacteria are in the tree that year, so that may be what’s affecting the lightness for you.
      3. We had one year with a lot of crystallization too! I’m pretty certain that’s just a matter of sugar concentration. It could be that you boiled it just past the syrup point (219 degrees F), or it could just be the particular batch. Regardless, it won’t hurt at all. Just scoop it out and call it maple rock candy. 🙂

      Hope this is somewhat helpful! Thanks for coming by!
