Updates from the Sugarbush

Based on the forecast, it’s hard to tell when our season will launch at the Ohio State Mansfield campus, but we’ve been hard at work readying the woods for whenever Go Time is.

3 years of single tree lateral lines came down from the ACER project that examined differences between sap production in Freeman’s (red x silver or “Rilvers”) maples.

Lateral lines in bad shape from wildlife damage or sanitation issues were replaced.  Some of these issues are pretty small and hard to spot unless you have your vacuum pump running.  Other wildlife damage…guessing raccoon or coyote here, pretty obvious.

Bucked rounds were hauled and split to feed our new demonstration evaporator at the also brand new maple pavilion (more on that later!).

We’re nearly done replacing all of last year’s spouts.

As we find drops and T’s that need replaced, we are shifting to a pin- or peg-style T so that we cut off the old spouts when taps are pulled at the end of season.

New trees that have grown into a minimum tapping size have been added to the system.  Surprisingly, our second main line that originally featured 99 trees when the tubing was installed in 2019 grew by 9 additional taps this year.  This was a good reminder to keep a diameter tape handy when getting your sugarbush ready for the season.  Sure, trees grow slowly, but they are growing and it’s sometimes surprising what just a few years can do when conditions are right.

End-line sensors are out gathering sunlight to keep our monitoring system operational, and we’re adding valves to the end of our main lines to facilitate a more complete and convenient sanitation regiment.

And our invasive species contract to control multiflora rose, particularly where it was worst along main lines 1 and 2, is already paying dividends with increased mobility and ease of access throughout the system.  A chest-rigged brush cutter was used to sever stem clusters in tandem with a timely and targeted application of glyphosate to the cut stem surfaces.  **This is a good reminder that any herbicide treatment in and around a working sugarbush should be done with caution!  Being cognizant of compound half lives, targeted treatment that stays where it belongs, and a well-trained applicator are keys to ensuring these sometimes necessary steps help and don’t hurt.**  Honestly, having the ability to freely negotiate through the woods wherever we please probably contributed to finding 9 additional taps along our second main line.  I also couldn’t help but notice that the majority of our lateral sanitation issues were cropped up around the second main line too.  Certainly trickle down penalties of thorny access because of a nasty invasive thicket infestation in the woods!

You literally could not walk through this area of the forest before, and the stem clumps that are left (and hopefully dead!) are the reason why.

One last major priority for this off-season will be attempting to remedy the long flat (at best!) stretches of main line between our pump house and where the majority of our taps start on main lines 4, 5, and 6.  I’m sure that will be a learning process complete with a couple of bumps in the road, but the goal is to perhaps install a couple lift options to show producers different ways of overcoming this common challenge in Ohio maple woods.  More on this last point later!!

Ohio 2023 Season Summary – “A Tale of Two Halves of Ohio”

I think everyone would agree the 2023 maple season was anything but normal.  It started with a fierce snowstorm in late December and ended with a chaotic mixture of warm and cold days.  If you are an Ohio maple syrup producer, how your season went seems to be a matter of location, location, location.  This winter was either too warm, too cold, or just right.  Depending on where you live and when you tapped, it was either all good or all bad.  Once again, Mother Nature had the final say.

The season kicked off early despite a surge of extremely cold weather at Christmas time, but warm weather arrived shortly after New Year’s.  The one thing Ohio producers have learned, when it looks and feels like tapping weather, you tap.  This year, many producers – I can confidently say more producers than normal – in both Northern and Southern Ohio started tapping in January.  Those tapping in early January experienced strong runs going into February, but many early tappers saw sap flow slow or completely shut off going into March.  The weather in February largely determined the success of your season.

Southern Ohio producers saw sap flow and sap quality end by the first week of March at the latest, many producers didn’t even make it out of February.  The jet stream kept the cold air pushed north, but abnormally warm temperatures plagued the southern part of the state.  More northern producers had strong sap runs into St. Patrick’s Day and beyond.  For the calendar tappers who traditionally waited until mid-February to tap, the season was average at best.  Overall, it was “ A Tale of Two Cities.”  Some northern Ohio producers experienced one of the best seasons in recent decades, but many southern producers experienced one of the worst production seasons in recent memory.

For producers who will associate the 2023 season with more positive memories, syrup quality held up remarkably well despite a season with so much variability.  Ohio made lots of Golden Delicate and Amber grade syrup.  The flavor was excellent for the most part until the warm weather ended the season.  Even then, a lot of lighter grade syrup was made right up until the last boil.  The biggest problem was filtering, excessive niter made it very difficult to filter and that high niter was reported from many producers statewide.  One of the reasons for outstanding yields was the good sugar content of the sap, averaging close to 2%.  Once again, the best yields were achieved on high vacuum tubing systems, but many bucket/bag producers had a good season as well.

Maple syrup is made all over the Buckeye State, but Geauga County is the number one maple syrup producing county in Ohio.  This year, the county lived up to its reputation in a big way, and production records were set across the county.  It was not uncommon to see syrup yields hitting or exceeding a half gallon per tap being produced.

Mid (Late?) Season Update

Chaos and unpredictability are apparently the new normal in the maple woods.  Fool me once, shame on me.  Fool me twice, well…you know the rest.  The past 2 sap seasons and current year’s production continues to highlight a new normal of early spikes in warm temperatures and the importance of being ready and willing to tap earlier than traditionally expected.  Producers wed to a historical norm will likely pay hefty cost this year.  Honestly, given the next few days of warm temperatures, we’re not sure our sap season will even make it to March 1st.

Our red x silver maples are starting to bloom and will likely be at or near full bloom by this weekend.  Though the buds on our sugar maples are still tight, the growing degree days (GDDs) are accumulating fast and tapholes are starting to dry up.  Hopefully those slowing tapholes are a combination effect of not just the warm temperatures but also the dry winter we have experienced.  I am not seeing much hope to erase the warm temperatures, but we are supposed to get drenched with a couple inches of rain tomorrow – that should help.

Here’s a photo I took this morning of the muddiest spot in our entire woods.  It is now bone dry and the used-to-be-mud is starting to crack and split.

The next week or two will tell the season’s tale – will we achieve an average season total, come up short again (maybe that’s the new normal?), or be surprised by a late spurt to make the year memorable in a positive way?  Only time will tell.

Getting Ready for Season

These are exciting and anticipatory times in the sugarbush as last-minute items are checked off the list.  As that list gets shorter by the day, we are turning our attention increasingly to the weather forecast and the all-important decision of “When to tap?”

Smart sensors are installed and grabbing what precious little sunlight has shone this January.  Charge batteries, CHARGE!

Lateral lines are all patched and tight with new spouts on the end of each drop.  These little side pulls, constructed from old, chewed laterals, have been a big help to us in tightening up our system.  First a before photo, second an after photo, and third a zoomed in photo of the side pull rigged with double end line hooks.

Additionally, a small pocket-sized carpenter’s level is worth its weight in gold for ensuring you have continuous drop from spout through lateral to main line to the pumphouse.

After an exceptionally windy and raucous 2022, we revamped and strengthened our sap tank cover.

An old broken valve has been replaced by new hardware (valve with the white handle is the new replacement), and I even took a little hacksaw to knock the end of one handle off to get a bit more clearance.

The next big to-do list item is to get our research canisters sledded out into position.  A fresh 3-5 inches of snow will make that task bunches easier.

Hopefully you are whittling down your checklist, or if you are a producer from southern Ohio or neighboring southerly state, you may already be making some syrup!  Heck, even as far north as Vermont, early tappers are getting a sap run already.  Hopefully this early warm spell is not indicative of yet another roller coaster season, but regardless – Wishing You a GREAT Season!

Ohio 2022 Season Summary – “Better Luck Next Year”

I suppose if you had to select one word that would describe Ohio maple syrup production over the last five years it would be “change.” Traditionally, maple trees are tapped on Presidents Day and the season runs until April. In the last five years, producers have been tapping trees earlier and earlier. In some cases in northeast Ohio, the last week of January. In more southerly portions of Ohio, many are tapping even earlier than that. In some years, producers have boiled a large percentage of their syrup in February. In many years – this year being no exception – by the time the Geauga County Maple Festival arrives, the actual maple season is a distant memory.  Seasons like 2020 will be remembered for excellent production. 2021 was dismal and forgettable for most. 2022 is a more difficult year to generalize.  A “one size fits all” label and commentary would be oversimplifying the season.

The first reports that reached my desk were that the 2022 season in Ohio was a bust. A half crop at best and for some that was true. For others, that was not the case. It all came down to location and timing. In parts of the state where you would expect a poor crop in a bad year, a full crop was produced. In more traditional areas of the Buckeye State, the result was less than favorable. Again, it all depended on the specific location of the sugarbush, when trees were tapped, and when the season stalled to a stop.

In Ohio, the 2022 season turned back the clock to a more traditional start. After a very cold and snowy February, the majority of the producers tapped within a week of President’s Day. The 2022 season was also a very intense season. The majority of the syrup was made over a short window between March 1st and St. Patrick’s Day. Heavy snows in February and heavier rain the first part of March resulted in an abundance of moisture in the woods. Two things happen when you have excessive amounts of precipitation. It translates into large volumes of sap, but it can simultaneously lower the sugar content within the sap. In 2022, that certainly was the case. A 60 to 1 sap to syrup ratio was not uncommon.

In the sugarhouse, producers reported that the niter had an uncharacteristic red cast that was hard to filter. For the majority of Ohio sugarmakers, the season ended on March 17th – St. Patrick’s Day. A few of the more adventuresome producers hung in until the last major freeze of the season on March 25th but the payoff was negligible. 2022 will be remembered as a continuation of the La Nina weather patterns experienced in 2021. Even with a more traditional start date, the season was again short with few big runs and low sap sugar. If you were lucky, you had an average year at best; however, most will chalk up 2022 as a 2nd consecutive disappointing season.

2021 Maple Production: NASS Survey in Review

The 2021 NASS Maple Syrup Production Report was published June 10th.  Production in the United States dropped 700,000 gallons from 4,111,000 in 2020 to 3,424,000 in 2021. Vermont production declined 500,000 gallons from 1,950,00 in 2020 to 1,540,000 in 2021. NY dropped 157,000 gallons from 804,000 in 2020 to 647,000 gallons in 2021. Oddly enough, Maine held steady missing last year’s production by only 5,000 gallons (495,000 gallons total). Maine’s production has been remarkably stable over the last three years. Of the seven states polled only Wisconsin showed an increase in production. The Badger State increased production from 265,000 in 2020 to 300,000 in 2021. Pennsylvania, the closest state to Ohio geographically and often mirroring our production, recorded 165,000 gallons in the 2021 NASS survey, down 13,000 gallons from last year. Ohio is not listed because they and six other states were dropped from NASS’ survey in 2019.

There were many reasons for this year’s decline in maple production. Nationally, sap was collected for 27 days compared to 34 in 2020. In most regions, prolonged cold weather delayed the season start even though this was not reflected in the statistics. The survey actually showed normal start and stop dates; the extended bouts of time when it was too cold for sap to run is obscured in the more general averages and reflected in the total collection days. Many states started around the first of February and then experienced a 3-week shutdown due to abnormally cold weather. This weather pattern was particularly hard on states like Vermont and New York. Once the weather did warm up, temperatures rose quickly and, for the most part, permanently dramatically closing the season by the start of April.

Another statistic worth looking at is number of taps. The number of new taps has not increased dramatically over the last 3 years in the United States. Taps counted 13,400,000 in 2019, declined in 2020, and rebounded back to 13,335,000 in 2021. Only the state of New York has shown a steady increase in number of taps each of the last three years.

Yield per tap is calculated as the amount of syrup (in gallons) produced per tap in any given year, and this measure is determined for each state. The yield per tap declined from 2020 to 2021, hardly a surprise given the shortened season. The United States average declined from 0.314 to 0.257. States like Vermont and New York saw a decline whereas Wisconsin was the only state holding levels above 0.300 gallons per tap.

What goes into a making a good yield per tap? Normally it indicates a higher level of production especially in the well managed sugarbushes. Consider the fact that this is a statewide metric that averages together producers on high vacuum with producers utilizing buckets and bags. A year like 2021 can be especially hard on bucket producers. Anything over 0.300 (roughly 1/3 gallon of syrup per tap) is considered good, and if a state exceeds this level, you can be assured the high vacuum, high volume producers are pushing 0.500 per tap or more. These are all good benchmarks to rank your personal performance as an individual producer. If you are producing just under a half gallon of syrup per tap in an average year you are doing okay. Is there room for improvement? Yes. There are producers in our own state of Ohio pushing one gallon of syrup per tap – a goal to shoot for!

Overall, the NASS 2021 report contained no surprises. Remember this is a domestic United States report only and does not reflect Canadian production. As we all know, north of the border production is what drives the maple market and that is not likely to change anytime soon.  Long story short, United States production fell this year, but syrup in reserve in places like Quebec will likely stabilize the overall market and prevent any large interruptions.

The 2021 Ohio Maple Syrup Production Report

Looking back on Ohio’s maple syrup season, production was lower than last year, but it could have been a lot worse. The season was short for most Ohio producers lasting 30 days or less. Ohio’s crop came in around 70 to 80 percent of normal overall. Because of the warm weather, syrup generally graded out in the Amber to Dark Robust range. However, there was still a fair amount of Golden made in the northern part of the state. If you look at the markets and what customers seem to prefer, this is right in line with the increasing demand for the darker grades of syrup. The earliest start dates were in the last week of January, but early starters were not rewarded this year. A massive cold air invasion that lasted until the 20th of February delayed tapping across the state. Most producers reported their first boil in the last couple days of February or first couple days of March. For nearly everyone, the season ended by March 25th. It is not often that you see seasons this shortened without a total collapse in production. Over the last several years, there seems to be a drop in the percentage of maple sap sugar as well. Percentages of sap sugar were on the lower end again this year averaging around 1.7 percent sugar.

To have a season end because of a combination of too cold, too hot, and too dry conditions is very unusual, but that is exactly what happened in Ohio. Extreme weather once again was the dominant factor in 2021. The end of 2020 and the beginning of 2021 saw a strong La Nina weather pattern take control of the region’s weather. This resulted in one of the warmest Decembers and Januarys on record. Cold and snow dominated the month of February setting up a chance for a good season even though the start was delayed.   When you consider what happened in February, everyone knew this season would be different from the last several. A massive Arctic air mass (Polar Vortex) drove deep into the heartland of America and dominated February, but the prolonged cold did set up some outstanding early sap runs when things finally warmed. Unfortunately, the ideal sugar making weather would be short lived.

Producers soon realized that the dominant warm weather experienced in December and January was not gone. Hello again La Nina! The return of warm weather did kick off a record sap flow that lasted about a week, but Mother Nature teased local maple producers with a very fickle freeze/thaw cycle that showed no signs of sustaining a sap run through the end of March. The final blow came on March 20th. This would be the last freeze followed by 4 days of 70-degree weather.  Most of the producers lamented the shortness of the season, but if we are honest with ourselves, the unique combination and variety of weather conditions could have dealt a worse blow to production.

We had an excellent season in 2020 and the demand for syrup was outstanding despite the pandemic. Now hopefully, the 2021 season was good enough to take care of the demand until the 2022 season arrives in 8 or 9 more months.

What to Expect for the Rest of the 2021 Ohio Maple Season

Just like snowflakes no two maple seasons are exactly alike.  No question about it, this season fooled me. After about 5 years of early tapping, along comes 2021.  During December and January, we experienced above normal temperatures leading to what many believed would be one more in a string of early tapping seasons.  Tapping in January has become almost routine across Ohio.  However, just like a deck of playing cards, every deck has 2 jokers.  This winter season we had two meteorological jokers.

The first was the presence of a strong La Nina with its trademark warmer and wetter weather conditions.  Hidden in the background far to the North was the second joker – the always volatile and never popular polar vortex.  A polar vortex is always a possibility during the winter months.  You never know when the jet streams will line up just right and push Artic air southward into our region.  This year we did not experience the full brunt of the vortex like we did in 2014.  The coldest air stayed well to the west of Ohio.  However, we did experience a cold spell that dominated 20+ days of February.

As result of the persistent polar vortex, the start of the 2021 maple season was pushed back until the last week of February and first couple days of March.  Even southern Ohio producers were forced to tap two to three weeks later than normal.  The first of March is not historically an abnormally late starting time for maple season in Ohio.  The one dominant factor that makes this season different is that our weather is still being somewhat controlled by a strong La Nina weather pattern.  The threat of an early warm-up and above normal temperatures are real.  And the first indication of that was the stretch of 60-70 degree temperatures experienced during the middle of the second week of March.  This was enough to trigger budding in red maples and silver maples of southern Ohio.

At the same time, many sugar camps in northeast Ohio set one day records for syrup production.  Sap flows were exceptional after the long cold spell of February.  As of March 12th, the same camps are reporting a half crop entering the third week of March.  The above normal temperatures experienced at the end of the second week, pushed the season close to the brink.  Conditions also caused a dramatic change in syrup grade, and Dark Robust and even Dark Strong profiles have mostly displaced the Golden grade of early season.

The next two weeks will determine the outcome of the maple season in Ohio.  OSU Climatologist Aaron Wilson is predicting a mixed bag of weather conditions for the rest of the month.  There will be some below freezing temperatures but nothing extreme.  For southern Ohio, the trend is for slightly above normal and for northern Ohio – normal temperatures.  Again, we may or may not see those colder low temperatures needed to reset the trees and delay budding.  What is also troubling is the lack of moisture.  2021’s recent precipitation trend is not typical for a La Nina year, and drier than normal conditions are slowly creeping into Ohio.  We need precipitation, snow preferred, to keep the sap flowing, but that key factor is largely missing in the forecast for northern Ohio.  At this stage, we need a hybrid of the two jokers to keep this season productive.

I will keep my prediction for the rest of March to myself, goodness knows the first two months of 2021 fooled me.  That said, I will be able to confidently predict the outcome the 2021 maple season in Ohio on the 15th of April.  What is it they say about hindsight?

From the Woods: Another ACER Project Update

Personal point of pride to share this photo of my 9 year old daughter Raelyn holding her first ever recorded datasheet.  She persevered for 4 hours of research last Sunday afternoon and evening to help me empty 75 sap chambers during a small sap run.  It has been a true team effort to pull off the ACER research project!  It seems uncertain right now just long the 2021 season will or will not last, but regardless, the 3 years of this project will allow us to answer some interesting and important questions for Ohio maple.
