The process of making syrup is an easy one: Tap trees, collect sap, boil it down to evaporate the water content and concentrate the naturally occurring sugars in the sap. But if you’re a homesteader new to sugaring, how do you evaporate gallons of sap effectively and efficiently? In this post I’m going to help you choose the right evaporator for backyard sugaring by sharing the pros and cons of a few methods that have worked for us, from DIY set ups, to investing in equipment that makes the job easier and more fun.
Choosing the Right Evaporator for Backyard Sugaring
The DIY Evaporator
We were brand new to this whole sugaring experience, and wanted to dive in with little investment. We bought a dozen or so metal spiles (taps) from Leader Evaporator (here is a less expensive plastic tapping spile), used clean milk containers and food grade buckets to collect sap, and boiled down the sap over an open fire.
The results were delicious.
One taste of the black walnut syrup, and we knew we’d be tapping trees every spring to come! (An aside: I’m often asked about the flavor of black walnut syrup. My assessment is that it is more earthy and nutty than maple syrup. If the two syrups were members of a string quartet, maple would be the violin, and black walnut would be the cello).
The pros of the DIY evaporator:
- Easy to set up with equipment you likely already have on the homestead
- Very little upfront investment cost
- A great use of scrap wood. We save branches from firewood collection to burn
- The canning pot does not offer much surface area, so evaporation takes longer
- A lot of wood smoke in the eyes!
*I should note that the process of finishing maple syrup can be done indoors on your stovetop or wood stove, but I do NOT recommend boiling your sap indoors – you will end up with a steamy, sticky finish on your walls (ask me how I know).
The Evaporator Upgrade
Once we committed to sugaring as a ritual of late winter/early spring, we wanted to upgrade our equipment just a bit. The solution: Taking that same open-fire canning pot idea but building a more sturdy concrete block base, and adding hotel pans to our equipment list.
You can see the set up in the photo above: Two long metal pieces (my husband is an artist blacksmith, so there is always metal lying around!) balanced on concrete blocks over an open fire. We still have our friend the canning pot in use, but have added a full-sized hotel pan.
My friend Abigail has a nice cinder block evaporator on her blog, if you would like to upgrade to a slightly more fancy version!
The pros of the evaporator upgrade:
- We were able to cook down more sap at once, making the process much more efficient
- We were able to use larger pieces of wood for a longer-lasting fire
- The hotel pans provide a greater surface area-to-volume ratio, speeding up the evaporation process
- We could have easily fit two more hotel pans on this set up, had we the equipment on hand
- It is challenging to lift and pour a hotel pan full of syrup!
- Still breathing in a lot of wood smoke each time you tend the fire
Investing in an Evaporator for Backyard Sugaring
Okay, this is where sugaring starts to get real. If you are committed to the process of making syrup, and tapping at least 20 trees, I recommend investing in some infrastructure to make the sugaring process more efficient and fun.
This can range from a full-on sugar house and permanent infrastructure, to a homemade evaporator, to anywhere in between.
We needed an evaporator that:
- Would allow us to boil down a larger quantity of sap more efficiently and safely
- Was not fixed in place (since we are currently renting a homestead)
- Poured off syrup easily
Have you ever gotten a thrill from a new tool – one that you can tell is so well designed and built that you know it is going to give you years of pleasurable use? That’s how I feel about the Sapling Evaporator.
The Sapling unit is a continuous flow evaporator, which means that one can simultaneously draw off syrup and add new sap without having to completely empty the pan in between boils.
I also really love that the steel barrel design, coupled with an exhaust stack, means that you can stand around the evaporator, smelling the sweet steam and not inhaling wood smoke.
Of course, there are more technical details about why it’s a great option for backyard sugaring, and I’ll let you read more about those here.
The pros of the Vermont Evaporator Sapling unit:
- An efficient, easy to use design that allows for more syrup made in less time
- An exhaust stack leads wood smoke up and away from your eyes and lungs
- The draw-off valve allows you to remove syrup from the evaporator pan without the sketchiness of trying to lift and maneuver a hotel pan
- This is an investment that will last for years (or decades!)
- This is a larger, heavier piece of infrastructure that needs to be stored and cared for properly. If you’re still dabbling, you may want to stick to the previous options
- The upfront cost is significantly higher than any of the options listed, but well worth it, in my opinion, for such a well-crafted, locally made piece of equipment
If you are not quite ready to invest in an evaporator, Kate Whelley McCabe, VT Evaporator’s CEO suggested an in-between option: Keep your homemade firebox or open fire, and invest in one of their Seedling or Sapling evaporator pans.
You’ll get the benefit of the continuous flow and easy pour off, with a lower price point.
In summary, choosing the right evaporator for backyard sugaring comes down to your level of commitment, number of taps, and ability to invest in infrastructure.
If you’re just getting started, or if you only have a few trees to tap, a DIY set up is going to work just fine for you. But once your passion for sugaring grows (as mine certainly did!) there are benefits to investing in some equipment that is going to make the process much more efficient and fun.
