Last Sunday March 13 I installed my usual three test taps.  Today March 16 the first tree is running sap.  I will tap all my trees today.

I am posting this in Growies because collecting maple tree sap for maple syrup is always my first food harvest of the year.  By the time I finish the sugaring season I will be into early spring planting season and my growing season starts up again.

Most of the trees I tap were planted by my grandfather in the 1940s and 1950s, some were planted by my father in the 1970s and 1980s, and for the last three years or so I have been tapping some trees that I planted back in the 1990s.  Trees I planted in the 2000s are still too young to tap.

Last year I made 16 gallons of finished maple syrup.  I turned 10 gallons into granulated sugar which filled two 5 gallon buckets.  That inventory is all gone, people know the season is upon us so they are already asking for it.  Processing maple syrup into granulated sugar is the very last and most tricky step in the entire process so I will not have any until three weeks from now.  Granulated maple sugar is by far my most valuable barter item.

By the way, granulated maple sugar is a one to one replacement for refined white sugar in recipes...

I do make maple cream but only by request because it is a royal pain to make and I charge accordingly.  Cash only, no barter.  When it turns out properly it is pure ambrosia, food of the gods.  It is incredible shmeared on fresh, homemade cinnamon raisin rolls just out of the oven.  I have eaten so much of the stuff I got sick of it and do not eat it anymore.

Sample jars of maple syrup from the 2019 harvest.  The three small jars on the right were boxelder syrup.


Photo shows my complete maple syrup harvest from 2019.  I stopped putting maple syrup into canning jars beginning 2020 due to the ongoing and seemingly perpetual canning lid shortage.  Now I put my maple syrup in gallon and half gallon jugs and only sell or barter it in bulk, if at all, because I turn most of my maple syrup into granulated sugar.


Photo shows the final screening process of a batch of granulated maple sugar.  It must be screened to get the candy nuggets out that form during the finishing process.


Photo shows a finished batch of pure, screened, granulated maple sugar.  This is $100US worth of granulated maple sugar and worth every penny for the amount of work I put into it.


Photo shows a two quart jar of maple candy nuggets and a two quart jar of granulated maple sugar.  I vacuum sealed these jars for long term storage.  People love the candy nuggets and always request them, I give them away as a treat and they go fast.

I tapped twelve trees today for a total of fifteen trees and thirty taps.  Six trees are already running sap.   I think fifteen trees is enough though I can always tap more if the sap run is poor this year.  Time will tell.  

The frost is deep this year...

such different worlds, tom! we tapped our few maples and more walnuts earlier, ended up pulling the taps probably a month ago down here. i have to admit one of the few points of envy from me towards you northerners is a decent sap season!

How did your season go?  Do you keep track of the sap to syrup ratio?

I am hoping for 30:1 or better which is typical.  My worst season was 34:1, my best season was 24:1.  My goal is to collect and process 500 gallons of sap with the hopes I can get to 600 gallons.  At 30:1 600 gallons should get me to 20 gallons of finished syrup, which would be a personal best and a nice round number to peak at.  I plan on cutting the entire project down by half next year, just too much physical work for a single person who is feeling his years.

I've made sugar before and I've also made a sugary tar that was a total fail.  I assumed that the "invert sugar" level of the syrup dictated if you can make sugar from it but your post makes it sound like you can make sugar from any maple syrup.  Am I misreading or optimistically assuming something?

Would you mind sharing your process for turning syrup into sugar?

it went well enough. the idea of a sugaring season in this area is generally laughable. it warms up too quick and rarely stays in a good temperature fluctuation for long enough to feel worthwhile. the ‘season’ lasted longer than usual this year, and our measly 8 taps ended up giving us somewhere around 70oz. of finished syrup. not much compared to your 20 gallons, but a nice little amount to be able to produce from the trees i have relatively easy access to.

i did not keep track of the ratio. since i’m tapping black walnuts and red maples (no sugar maples here) i’d expect a 60:1 or worse, but my record keeping was non-existent on this project.

You are correct, invert sugar ratio dictates whether you can successfully make granulated sugar or not for that season.  If the ratio of sucrose, glucose, and fructose are off it will never granulate no matter what you try to do.  For that season you have to be happy with just making a fresh batch of syrup.  I have made my share of tar thinking I was doing something wrong.  Once I understood the issue then I tried doctoring the syrup with the correct sugars to try to rebalance,  I also tried cutting it with syrup I had remaining from previous years that I knew made good sugar.  Waste of time all of it.  I learned to understand that Mother Nature was in control, and sometimes I simply do not get what I want.  Makes me appreciate it more.

Every year when I am done finishing all the maple syrup to temp I then get ready for sugaring.  I process a pint of syrup as a test batch on the stove to see if it granulates.  If it turns to tar then I only wasted a pint, and I end my season.  I learned to always keep a five gallon pail of granulated sugar as a backup supply against a failed year.  I do not consume much sugar so I am still willing to barter some off, but I double its value.  I have been making granulated maple sugar for nine years now, this year will be number ten.  I discount the first three years due to the steep learning curve.  Out of six years I have had two years where the syrup did not turn into sugar properly.  The last two years I made the best sugar I have ever made, it was wonderful.  I am curious how it will turn out this year.  Hoping for the best, I have impatient people bugging me that they need more sugar and I have not even begun collecting sap yet.  

There are some decent videos of the process online.  I learned how to do it all by myself with no such aids so I had a steep learning curve.  Now I have the experience to see all the stages and know how things are going just by appearance.  I never use a thermometer anymore, turned out to be just an unnecessary distraction.  Now I can easily get sugar by taking a batch from start to finish in a pan on the stove if I want to, it is fun to show visitors how it works and they are always amazed.  Still fascinates me as well.

My "secrets" are simple:  

1.) Most Important Part 1:  DO NOT OVERHEAT.  No matter what size batch I do I never have the stove setting higher than medium, and when the final stages begin I gradually take the dial down.  At the end there is so much heat built up in the product that you can turn the heat completely off.  

2.) Most Important Part 2:  BE PATIENT.  Do not rush any step of the process.  Rush, cut corners, you will fail.

3.) Most Important Part 3:  BE SAFE.  Should not need explaining.  I wear eye protection.  I wear long sleeves now.  Once I happened to spill a glob of the superheated maple goo onto my arm.  It was a truly amazing experience of pain and I prefer to avoid that ever happening again.

4.) Do not overthink the process.  It is a simple process once you know how to do it and have some experience under your belt, but it never stops being potentially tricky and dangerous.  It requires full focus and attention.  And never have children around that batch of superheated boiling goo.  Be smart about things.

5.) Do not use a thermometer as it is more of a distraction than an aid.  It really does not tell you anything you need to know because the point of the whole exercise is simply to heat up the syrup enough to take the remaining water out of it as steam.  Contrary to what many people say there is no final finish temperature, every batch is finished when all the water is boiled/steamed out of the syrup.  If you are patient and do not overheat I guarantee you will succeed every time (assuming the invert sugar ratio is correct).  

Overheating will set syrup on to the bottom of the pan, the syrup will scorch and the batch will be either be ruined or the finished sugar will be off color and taste bad.  Gentle stir occasionally, increase stirring as the batch progresses.  When the the batch turns to the consistency of wet sand then remove from heat and stir and fold continuously until it releases the last of the water as a burst of steam.   (Just before this stage is when people will put the batch into a mixer to final finish.  This will strain and possibly burn out the motor of the average home kitchen mixer, so good luck.  I burned out my KitchenAide.)  When it is nice granulated sugar and you think it is finished then screen out the candy nuggets.  Let the sugar cool to room temperature, then place the cool finished sugar into a sealed container as soon as possible because the sugar immediately begins to absorb humidity from the air.  In storage the sugar will always harden, but it breaks up easily and can be easily rescreened.  This is because it is all natural, while store bought refined sugars have chemical or silicon dioxide anticlumping agents in them, which a person then consumes when using the sugar.  Personally I have no problem dealing with my clumpy but pure maple sugar.

I have photos of my entire process but I do not have time to deal with resizing and uploading images at this time.

By the way, anyone can try to make their own maple sugar by purchasing a pint or quart of maple syrup from the store.  Does not need to be top shelf brands but needs to be PURE.  They do not always work due to the invert sugar issue.  I have had success doing this as an experiment using several different brands from different stores, but I also had a few failures.

Update:  

I had five days of collecting sap then the weather turned for the worse and the sap stopped running.  Around here we call this a false sap run, a fairly common situation so no worries but it tends to make the less experienced folks panic a little bit.  The trees will do their thing in their own time.  Sap amounts collected have varied greatly from tree to tree, two trees were not even running yet while a few trees have produced ten gallons and the rest of the trees somewhere inbetween.  We had a deep frost this winter.  The ground was still mostly frozen up even with the warm weather we had, thawing ground triggers trees to awaken and start pumping sap.  Two days ago the temperature reached 60F, now the extended forecast is for 30s to low 40s F for daily highs and low to mid 20s F for nightly lows, which means sap will be running slowly if at all.

I did one day of processing, my shakedown day, so I worked out all the bugs and everything is ready to go for when the big push begins. I worked through 65 gallons of sap but was a short day of processing due to some unexpected equipment repairs.

I have 60 gallons in cold dark storage ready to use when I start up processing again.  I do not know when that processing day will be because of the weather.  Sap can keep for a while if stored properly, but if that stored sap gets cloudy or off-tasting then I will dump it all and resanitize the buckets.  I do not make crappy product and quality product always starts with nice fresh sap.

Yesterday was not a day for outdoor processing due to wind, rain, and snow, so I finished off that first batch of concentrate indoors.  Ended up with around 2 gallons of decent but not excellent finished maple syrup, I expect better when the trees finally get going.  No exact numbers yet but I estimate around 30:1 sap to syrup ratio (meaning I have to boil off 30 gallons of sap to get one gallon of finished syrup).  That ratio often changes throughout the sugaring season as the sugar content in the sap varies from day to day and tree to tree.

An interesting note:  This year my first processing day happened to be on the exact same day as my final processing day last year.  The sugaring season is different every year...

Update:

I processed sap on the arch on Saturday and Sunday.  Processed the concentrate down to finished syrup today.  My total for this season so far is 6.5 gallons of finished syrup from 158 gallons of sap, for a sap to syrup ratio of 24:1.  That is an excellent ratio and tied for my best.  The last, most recent 2 gallon batch of syrup is excellent quality.  I am going to set this good stuff aside for a couple of folks with whom I barter, as they requested.

I have a long way to go to get to 20 gallons of finished syrup.  I admit I am having my doubts that I will get anywhere near this goal, but it is just a goal.  I will take whatever Mother Nature gives me.

The maple sugaring season is unusual and sporadic this year due to deep winter frost that still has not been broken, and lingering cold, windy weather.  Sap is barely running on some trees, not at all on others.  I have not collected sap for four days, small amounts of sap that remained in buckets has frozen solid.  Forecast is for more cold weather, with luck I hope to be processing again this coming Sunday or next Monday.  All depends on the weather and what the trees want to do.

This project is behind the norm but not totally unusual.  In the past I have processed sap as late as April 16.  We have had heavy winter snowstorms as late as the second half of April.  It is Minnesota after all, our highly variable weather in springtime has always been the norm.  It either makes you strong or kills you off...

Update:

I had a busy week collecting and processing sap.  Very busy days inbetween the rains, freezing rains, snow, and unusually frigid temperatures.  When the weather keeps me indoors then I process concentrate down to finished syrup and try to get other chores done that are getting neglected.

Tough maple season this year but I am working through it.  Worked a twelve hour day yesterday and boiled off 80 gallons of sap, my personal best for one day of processing.  Windy, rainy day kept me inside today, and more rainy weather will stop me from processing outside on the arch for the next two days but Friday and Saturday look good.  

Yesterday and today trees have begun to shut off so the season is finally winding down.  I am fine with that.  So far I have processed 450 gallons of sap and gotten approximately 15 gallons of finished syrup, for a 30:1 ratio.  Nice flavor overall, dark syrup.  I have approximately 200 gallons of sap remaining in stock.  I am willing to process sap for two more days and that is it for me, I am worn out and my interest and ambition is fading fast (I know I am getting into trouble when I forget what day of the week it is).  My goal this year was to beat my previous record of 16 gallons of finished syrup.  I am almost there and will push through to achieve that goal if at all possible.  

After this year I am winding down my operation due to physical issues.  I will reduce down to just 4-5 gallons of finished syrup every year, which is a realistic amount that will make the project more fun for me once again, which was kinda the whole point originally.  Somewhere over the years I lost sight of that...

I tapped birch trees last year and made some stuff. At that time, I thought my maples weren't suitable because they aren't sugar maples. Since then, I've read several accounts of people tapping a wide variety of maples, so I figured I'd try. I tapped five trees on the 8th. Two failed to produce, so I've removed the taps and buckets, but I got eight gallons from the three other trees. I don't have a proper boiler set up (or an RO filter, which seems to be the big thing) so I'm boiling on the stove and running our vent-hood. I don't expect to get anything resembling production quantities, but instead I'm pursuing this as a proof of concept for future years. It would be great to end up with a quart of syrup, to be honest. But the real draw for the future is being able to produce my own granulated sugar and stop buying it in.

I do not use an RO for various reasons:  I prefer to put in the time needed to do the work the way it has always been done.  I am also very leery of taking shortcuts with anything I do in life, I always seem to pay a price when I take shortcuts.  The cost of setting up an RO is another issue for me, though it is not too expensive for homebuilt units I prefer to do maple sugaring using minimal investment.  A person is then also reliant on having to acquire maintenance and consumable RO parts that might not be readily available someday (a very realistic possibility these days).  For me I can harvest sap from the buckets, light a fire using my own cut and stacked firewood, and just start boiling.  Don't get me wrong, my methods take a heckuva lot of time and physical labor, but I pretty much do the process the way it has always been done (with some exceptions).  I could partner up now that it is getting hard for me to do this project alone but I do not want to open up that can of worms because I know I can outwork most people due to my mindset, stubborness, and refusal to quit when things get tough.  Instead of having a partner and splitting the finished product I would rather just cut my production goals in half, and reduce further as I get older.

It is good to hear you are doing some testing this year, I think it is worth checking out and going small initially is always best.  That is how most people start this hobby.  Years ago I started with one tap in one tree and processed on a shielded firepit and got one pint of smoky but edible syrup.  Even though it was not that great it was the best maple syrup I ever tasted because I made it.  That was all it took to get me hooked.  Some day I will have to go back into my records and add up all the production numbers.

I very much agree with you regarding having the ability to produce, on site, an all natural sugar product that happens to be a one-to-one substitute for refined white sugar.  Around here I am the only person who makes it and though it has taken time to get the word out I now have regular customers who either purchase outright or barter to acquire this product.  In tough times people will always need/want/crave sugar, salt, caffeine, alcohol, tobacco, chocolate, and other similar stuff so granulated maple sugar will always be in demand if there are shortages of refined white sugar (another very realistic scenario these days).

Season Update:

The trees are finished here.  I pulled my taps yesterday while I did my last day of processing.  My season total was 600 gallons of sap processed, I tossed away 30 gallons because I reached my goal plus I was physically and mentally burned out and didn't want to do any more.  Was a tough season but I have had worse, I feel I earned what I got this year.  Still had plenty of firewood remaining.

I processed concentrate all day today and finished off approximately 5.5 gallons of syrup.  I have one more batch to finish off tomorrow, then I have to spend a day cleaning up and putting away equipment.  I do not have the total yet but I expect around 19-21 gallons of finished syrup for the season.  The syrup is stored temporarily in sealed five gallon pails in a cold, secured outbuilding.  The next step will be testing to see if the syrup makes decent granulated sugar.  If it does then I will process most of the syrup into sugar and will bottle the remaining syrup into half gallon jugs.  With Easter causing some delays I expect to be finishing up sometime next week.  Just in time to get focused on early garden planting...
