Tapping & Tubing
Producers encouraged to find their 20-day 'money window'
Peter Gregg | January 16, 2024
THOMASTON, Conn.—When to tap?
That’s always the sugarmaker dilemma every season but this year it seems more pronounced than others.
Wild weather and big temperature swings across the Maple Belt has had producers excited one minute and hesitant the next.
Contributing to the matter are Facebook posts from big producers who are forced to tap early because of the size of their operations, and capture early sap runs in December and January.
When to tap was the big topic of conversation this weekend at the annual meeting of the Maple Syrup Producers Association of Connecticut.
“I’m not sure when I’m going to start this season,” said Mat Wilkinson of 800-tap Wilkinson Maple Farm in Columbia, Conn.
Offering some perspective was the keynote speaker at the meeting Bradley Gillilan of Gillilan Family Maple in Fletcher, Vt. who is a tubing installer and consultant to sugarmakers across the nation.

Vermont sugarmaker offers tips on tubing cleaning
Peter Gregg | November 3, 2023
SOUTH WOODSTOCK, Vt.—One of the biggest debates in maple is over the best method for cleaning tubing, or even bothering to clean it at all.
At 1,200-tap Top Acres Farm in South Woodstock, Vt. sugarmaker Mary McCuaig has developed what she says is a tried and true method.
"We use a weaker chlorine solution and begin cleaning as soon as the season ends," she told The Maple News.
"This method has allowed us to avoid replacing spouts and droplines annually and still keep yields high," McCuaig said.
"We average over half gallon of syrup per tap, and our sap is clean, starting with the first sap run."
McCuaig has posted three YouTube videos explaining her method under her YouTube channel- marymccuaig3249. [ MORE ]
Proctor reports on 2023 season barb-spout results
By Timothy D. Perkins & Wade T. Bosley | May 18, 2023
UNDERHILL, Vt.—The outermost rings of wood in maple trees have the highest sap flow rates and have sweeter sap than the wood found deeper in the tree.
In addition, during the early part of each season there are several periods when thawing is too brief and shallow to allow sap to be collected.
This is because typical maple spouts have elongated barrels that are inserted well into the wood to anchor them in place. While this design feature of spouts reduces the tendency of sap to dislodge during deep freeze periods, it doesn’t permit sap collection during brief thaws.
Taken together, these factors reduce the amount of sap that can flow from tapholes.
Over the past five years researchers at the UVM Proctor Maple Research Center have explored different approaches to reducing these limitations in order to maximize sap yields.
One obvious solution would be to shorten the spout barrel to permit sap to flow more readily from shallower wood tissue. A consequence of this is reduced spout stability and an increased probability of spout heaving during deep freeze periods. [ MORE ]
Farmblox to host open house this weekend in St. Albans

Raging debate on 3/4 pipe
Peter Gregg | April 10, 2023
PLYMOUTH, N.H.—Love it or rip it out?
A debate is starting to swirl between expert installers on the effectiveness of three quarter inch mainline. Some experts are advising that the narrow mainline does not do well transferring sap on vacuum.
“Regardless of the situation, airtight or not, there are always downsides to using 3/4 in. tubing,” said expert Joel Boutin, an advisor for the Quebec Maple Cooperative. Boutin was a guest speaker at the Vermont Maple School in December who emphasized his dislike of 3/4 inch pipe.
Boutin said that 3/4 inch mainline often acts like 5/16ths lateral lines, overfilling with sap and taking up too much space for air. He said big bubbles will form in the tube and decrease vacuum the further away from the pump.
“3/4 tubing can only carry sap from very few taps with the new yields people can get now,” Boutin told The Maple News. “In fact, it is less than 100 taps if you do more than 6 lbs per tap." [ MORE ]
Many sugarmakers sticking with 3/16 tubing
Peter Gregg | March 29, 2023
BOW, N.H.—The reputation of 3/16ths tubing has taken a beating the past couple of years, with sugarmakers gloriously ripping it out of their woods and declaring it a short lived fad.
But there are plenty of sugarmakers that have stuck with the natural vacuum technology, and say that it works for them, and is effective in getting high vacuum from gravity instead of a pump.
The key? Lots and lots of slope.
“Yes it seems the better the slope the better it works and less likely it is to plug up,” said Brandon Daniels of Daniels Pure Maple Syrup in Grassy Meadows, W.V.
Daniels is something of a 3/16ths guru in the Mountain State, where the narrow tubing still rules.
“We are blessed to be able to tap trees on eight properties and we have 2,500 taps on CDL 3/16 natural flow vacuum,” he said.
West Virginia has some of the steepest slope in the Maple Belt, which is why, anecdotally, the technology seems to work there.

Tips from Glenn: Goodrich shares his secrets
Peter Gregg | February 14, 2023
PLYMOUTH, N.H.—Sugarmaking legend Glenn Goodrich was the featured speaker at the NHMPA annual meeting on Jan. 21, offering advice on tapping, vacuum and boiling.
“Getting a true round hole in the trees is essential,” Goodrich told producers on his tapping methods. Goodrich has a 160,000-tap operation in Eden, Vt. and Cabot, Vt. and is recognized as one of the U.S.’s premier sugarmakers, winning countless awards.
Goodrich says as he and his crew of tappers march from tree to tree, he estimates he taps a tree in 35 seconds before moving to the next one.
“I fire the drill to the highest speed the drill can spin,” he said, before sinking it into the tree at a maximum depth of no more than 2 inches, or sometimes just one inch on marginal trees.
After the hole is drilled, he uses a nylon-headed tapping mallet to knock in a spout, but with not too much force.
“It’s all in the wrist,” he said. “We’re not knocking in the spout with a 24-ounce Estwing hammer as hard as we can. Don’t do that.”
He said most taps usually get “six hits,” with the mallet.
Once he’s tapped, the vacuum generally runs continuously at the farm.
“I will shut off the pumps only if I know the trees will be frozen for at least 10 hours,” he said. [ MORE ]
What to do about weepy tapholes?
Peter Gregg | February 10, 2023
FAIRFIELD, Vt.—What to do about weepy tapholes?
As sugarmakers across the U.S. race into the woods this week during an unusual warm-up, some are scratching their heads over a common phenomena—sap leaking out of the taphole and spreading around the trunk.
Expert tappers generally agree that the leaks are caused by poorly drilled holes.
“Wobbly or oval holes, I would say is the cause,” said Evan Branon of 80,000-tap Branon Family Maple Orchards in Fairfield, Vt. Branon is the inventor of the Precision Tapper, a drill attachment sold by CDL that helps the sugarmaker drill consistent and straight holes in the tree.
Still, for those who don’t own that equipment, sugarmakers can ensure proper holes by using good technique.
“We always want to use two hands to steady the drill,” said 160,000-tap sugarmaker Glenn Goodrich of Goodrich Maple Farms in Cabot, Vt. who led a seminar on tapping at the New Hampshire maple school last month.
Goodrich said that if a sugarmaker finds a weepy hole after drilling, he/she should not go back and pound the tap in harder with the mallet.
“Just leave it alone and check back on it in a few days,” he said, suggesting that the hole oftentimes will seal up on its own.

Maxed out sap? Trees can handle it, say researchers
Peter Gregg | January 5, 2023
UNDERHILL CENTER, Vt.—Are the trees maxed out on sap production? Not yet, say experts.
With several sugarmakers starting a season in November or December and pulling sap from the same trees and same tapholes all the way to late April with high vacuum running every single day, questions are being asked about the ultimate sap capacity of a tree.
“Are we at the limits of extraction? No, I don’t think we are there yet,” said Dr. Timothy Perkins, director of the UVM Proctor Maple Research Center, during an online Q&A session last month.
Dr. Abby van den Berg, also of the Proctor Center, concurred.
“There is a question of the reservoir—we don't know what is there,” she told sugarmakers.
“We think we are taking a reasonably small percentage of the tree’s reserves.” [ MORE ]
Sugarmaker endorses “pattern tapping”
Peter Gregg | December 22, 2022
DUNMORE, W.V.—Adam Taylor of Frostmore Farm in Dunmore, W.V. practices sequential or “pattern” tapping by marking the tapholes from year to year with colored paint.
“We tend to move in the same direction every year, always to the right, so we dont get partitioned wood,” he said.
Taylor says he also likes to tap “really high in the air” to avoid tapholes from long ago where buckets were once hung from this tree.
“We get good sap quality every year,” Taylor said. [ MORE ]
Early spout deployment ok'd by Proctor researchers
T.D. Perkins, W.T. Bosley, A.K. Van Den Berg, S.J. Abair | September 12, 2022
UNDERHILL CTR.—It is well recognized that spout and dropline sanitation heavily influence sap yields in maple tubing systems.
The drop, including both the tubing and spout collectively, accounts for almost 90% of the sanitation effectiveness in terms of sap production, while the lateral line and mainline have only a small influence on yield in terms of sanitation.
Of this, the spout is by far the most important component, although annual replacement of the spout alone is not enough to achieve maximum production on used droplines.

From Pails to Pipelines:
Paul Post | June 26, 2022
BURLINGTON, Vt.—If the maple world ever creates its own version of Mount Rushmore, the tubing pioneers from the 1950s would make excellent candidates.
Nelson S. Griggs and George B. Breen of Vermont, and Robert M. Lamb of Central New York, led the way with development of plastic tubing for sap collection, which laid the foundation for today's highly-efficient, modern production systems.
Historian Matthew M. Thomas, PhD, discussed their work and the evolution of sap gathering in a fascinating online presentation, "From Pails to Pipelines: The Origins of Plastic Tubing in the Maple Syrup Industry."
Thomas created the website MapleSyrupHistory.com and has authored two books, "A Sugarbush Like None Other" and "Maple King: The Making of a Maple Syrup Empire."

Maple 101: Expanding through tapping tenure agreements
Mike Rechlin | June 1, 2022
FRANKLIN, W.V.—The issue of tree access can be problematic for many maple producers.
Just like leasing pasture to support a growing herd of cows, many maple producers lease trees to support increased production.
This allows syrup producers to expand production beyond the forest resource they have available on their own lands.
Depending on the demand for trees to lease, a landowner can expect from $0.50 to $1.00 per tree.
A good sugarbush can have 70 taps per acre, realizing an annual income to the landowner of between $35 to $70/acre.

Tapping tip: Cornell experts recommend 'Pattern Tapping'
Peter Gregg | February 3, 2022
LAKE PLACID, N.Y.—Tappers this season should try pattern tapping and marking old holes with paint.
That was the advice from Adam Wild of the Cornell Maple Program, who led a discussion on tapping during the annual meeting of the Massachusetts Maple Producers Association last week.
Pattern tapping is recommended so sugarmakers avoid hitting old tapholes.
“The reason we use pattern tapping is it helps eliminate hitting non-conductive wood,” he said. [ MORE ]
Experts offer pre-season sugarbush tips
Peter Gregg | January 5, 2022
HEBRON, Ct.—Straight, tight and downhill.
That was the simple advice to sugarmakers from retired Leader Evaporator legend Bruce Gillilan.
Gillilan led a tubing demonstration this fall in sugarmaker Ron Wenzel’s spectacular 412-tap bush in Hebron, Ct.
Gillilan said when determining what trees to tie into laterals, outstretch one’s arms up the hill and only connect trees that fall in between.
Other tips? Laterals should only connect between three and five taps per run, he said. Sometimes more if using 3/16ths.
Experts also say to use 36 inch droplines to reach more surface area of the tree, avoiding non-conductive wood. [ MORE ]

Sugarmaker shares experiences with 3/16 sanitation
Art Krueger | September 3, 2020
SHREWSBURY, Vt.—My family’s sugarhouse finally made some significant breakthroughs using 3/16 tubing.
We managed to completely empty our woodshed of 30 cords and needed to scrounge several cords more to finish up. Certainly a measure of success since, after all, emptying the woodshed is the real objective.
Additionally, we’ve had our best year ever reversing the disappointing trend of the past several years.
We’ve even had to sell over 5000 gallons of sap to a neighbor as we were not able to boil it down fast enough.

Avoid stained wood when tapping
Peter Gregg | August 6, 2020
NEW CASTLE, Ind.—Sugarmakers are encouraged to use longer drops, shallower tapholes and spend more time looking for good tapping surface when they begin tapping for the 2021 season.
That's the message from University of Vermont Extension maple specialist Mark Isselhardt when he spoke to Indiana producers during the annual meeting of the Indiana Maple Syrup Producers Association in New Castle, Ind. last winter.
“You will get 75 percent less sap if you tap into stained wood,” Isselhardt said.
Indiana sugarmakers who tend to use sap bags or buckets rather than pipeline in their flat woods are better suited to spend time seeing how each tree is producing.
“On buckets you know what each tree is doing whereas on tubing it all blends,” he said. [ MORE ]
Sugarmaker shares experiences with 3/16 tubing sanitation
Brandon Daniels, CDL West Virginia & Virginia | July 22, 2020
DAWSON, W.V.—There has been much discussion and some research given to 3/16” and the reduction in flows that most see after the first season.
The information in this article will not be referred to as research, but it will be presented to help maximize your production on 3/16” tubing in seasons two through ten.
Before we jump into that, I will provide a little more information on our facilities and my background.
I started producing maple syrup over thirty years ago with a 2x3 stainless pan in the back yard and ten taps as a young teenager.
This has grown to a modern state of the art operation.
I am running 2,400 taps +/- 10 on 3/16” tubing in five different areas. These taps run into round bottom stainless tanks produced for maple sap.
In all of the areas we have taps, they are within approximately 1.5 miles of each other.
In all five of these locations, there are taps on slopes that face more than one direction and on the 2,400 taps, we have taps that face every direction on the compass. [ MORE ]
Sapline and spout recycling program in Northern Vermont
Richard Backer, Northwest Vermont Solid Waste District | May 26, 2020
GEORGIA, Vt.—Sugarmakers can recycle old tubing this spring instead of throwing it out with the trash.
The Northwest Vermont Solid Waste District (NWSWD) operates a small Material Recovery Facility (MRF) located at its administrative office adjacent to the Interstate 89 - Exit 18 interchange in Georgia, Vt.
The district is a municipally chartered organization fully serving 19 towns in Grand Isle and Franklin counties. NWSWD has an ongoing modest program to recover and recycle HDPE sapline.
Small and large syrup producers and county associations are encouraged to call NWSWD with inquiries or questions on recovery and recycling HDPE sapline.
Please call NWSWD at 802.524.5986.
If the sapline is clean, without contaminate plastics including spouts, tees or PVC we will take tubing from anyone in the state.
Sugarmakers in other states are welcome to bring their tubing to us as well, as long as it's clean.

UVM compares 3/16” and 5/16” tubing sanitation
T.D. Perkins and A.K. van den Berg, University of Vermont Proctor Maple Research Center | January 3, 2020
UNDERHILL, Vt.—It is well recognized that microbial contamination of tubing systems can result in a substantial loss in sap yield if untreated.
Over a decade of research and maple industry experience has produced a range of possible strategies to address sanitation-related issues in 5/16” tubing systems (Perkins et. al. 2019).
Although rapidly adopted by many maple producers, due to the relatively short time period in which it has been in widespread use, there is far less understanding of sanitation in 3/16” tubing systems (Wilmot 2018).
To address this knowledge deficit, we conducted a multi-year study at the UVM Proctor Maple Research Center to examine sanitation-related losses in 3/16” tubing systems to determine which approach(es) might best mitigate sap losses due to sanitation. [ MORE ]
Sugarmaker weighs in on cleaning 3/16 tubing
Arthur Krueger | August 4, 2019
SHREWSBURY, Vt.—He are my 2019 observations on Calcium Hypochlorite bleach for cleaning 3/16” sap tubing at our sugarbush in Central Vermont.
After the 2018 season we cleaned our 3/16” tubing system with calcium hypochlorite bleach. This bleaching solution is made by adding 1 pound of “Zappit” Cal-Shock 65 to 200 gallons of water.
On 80 percent of the sugarbush we cleaned the system by pumping up air and the bleach solution through the laterals. Later we cleaned the drops by squirting bleach solution into the spouts using wash bottles.
These spouts were either replaced with new spouts or used bleached spouts for 2019.
(I found that it is possible to easily reuse a 3/16” fitting by boiling it and removing the bit of attached tubing with pliers. The fitting is not damaged by this treatment and is able to maintain high vacuum. We found no difference in performance between these used bleached spouts and brand new spouts.) [ MORE ]
November tappers might go again
Peter Gregg | October 25, 2018
HOBART, N.Y.—With the calendar turning to November, some sugarmakers are getting ready to start their season.
“We might do about 2500 next week,” said Ben Holscher of Roxbury Mountain Maple in the Catskills region of New York.
Last year the Holschers tapped November 15.
Their effort was not necessarily part of a “fall tapping” experiment, but rather to get a very early start on the 2018 sugaring season.
“We’ve been tapping earlier and earlier in January anyway,” said Ben Holscher, 28, one of eight siblings in the Holscher family. “So what’s it going to hurt going a month or so earlier than that? Might as well.”
“Yeah, it’s been weird,” said Dave Holscher, family patriarch, during a boil last Dec. 6. “We’ve had better sap weather the past three weeks then we did all last year during sugaring season.”
In their valley, November and early December gave them a long three week stretch of perfect freezing nights in the 20s and daytime highs in the 40s.
Trees were gushing.

Spout color – Does it matter?
Dr. Timothy D. Perkins, Abby van den Berg, Mark Isselhardt, Brian Stowe and Wade Bosley | Sept. 28, 2018
UNDERHILL CENTER, Vt.—Among the many things that are debated in the maple industry, the effects of spout color on sap yield seem to have as many opinions as there are colors in the rainbow.
Spouts from maple equipment manufacturers are now available in a wide range of colors. Often this selection of color is simply a tool for large-scale producers to keep track of different tappers by assigning them a color, but producers also want to know if spout color has any effect on sap yield.
There has not been a lot of recent research on the subject. Centre Acer conducted a study a few years ago, which concluded that white spouts produced 7% more sap than black spouts (as reported by CDL in their 2018 equipment catalog, page 10).
However, there is likely to be variation from one year to the next depending upon the weather regime experienced during each season. Other factors such as spout design, manufacture, and overall spout/tubing sanitation levels are also likely to slightly affect the results.

Strategies for maintaining high sap yields with 3/16 tubing
Tim Wilmot | August 3, 2018
Sap yields from 3/16” tubing on a slope compared to yields from 5/16” tubing are generally very good in the first year, particularly with gravity tubing, but also in many cases when using a pump—as described in two recent articles in The Maple News.
However, yields reported by many users begin to decline, usually by a moderate amount, after the first year. This is particularly true if the tubing is not cleaned at the end of the season.
In part, this is due to the nature of the tubing, which holds onto sap much more tightly than 5/16” tubing, generating natural vacuum in this manner; in some cases it also holds onto sap containing bacteria and yeasts. [ MORE ]
3/16ths guru Tim Wilmot: Using 3/16th tubing with a pump
Timothy Wilmot Researcher, Dominion & Grimm Inc. Retired, University of Vermont Extension Maple Specialist | Jan. 25, 2018
In addition to the advantages that 3/16” tubing provides in creating natural (gravity) vacuum on a slope, there is also an advantage that small diameter tubing can provide in some pumped systems. As is true with an all gravity system, the goal is to maximize vacuum at each taphole. Research has shown that an increase in vacuum at the taphole is accompanied by a steady increase in sap production—the relationship is about 5% more sap for every additional inch of mercury. In many pumped systems, because of friction loss and the capabilities of the pump itself, the vacuum at the taphole is less, sometimes much less, than the maximum that is possible at that elevation.
On a slope, the vacuum that can develop in 3/16” lines can increase what is achieved in the mainline by the pump, and this increase may boost production. The vacuum in the small lines is developed by the weight of the sap, while the vacuum in the mainline comes from the steady removal of air by the pump; together they form what I call a hybrid. This type of system is somewhat newer than the all gravity 3/16” system, and its design, for example the optimum number of taps per line, is less straightforward.
This article summarizes the research that I have conducted on 3/16” hybrid systems; unless otherwise noted, all of the results reported here are my own.

3/16ths guru Tim Wilmot. The gravity of it all.
Tim Wilmot, University of Vermont Ext. Maple Specialist (retired) Researcher for Dominion and Grimm Inc. | Jan. 13, 2018
The use of 3/16” tubing for sap collection began as a series of experiments that I conducted while working at the University of Vermont Proctor Maple Research Center.
The goal was to devise a gravity sap collection method that would improve production for sugarmakers with small operations who typically collected much less sap than producers using vacuum pumps.
Over the past 8 years I have continued to conduct research with this tubing in an effort to learn more about its potential uses and possible shortcomings, both for gravity and pumped sap collection.

3/16 tubing thoughts and observations
Arthur G. Krueger, P.E. |
In the December 2015 issue of Maple News, a person discussing 3’16” tubing said that one needed 10’ of fall for the system to work. At best, 10’ would only give a vacuum of 9” of mercury (9” hg on your vacuum guage). Not exactly a high vacuum system. 40’ or 50’ of fall is required for high vacuum. If set up right, these systems will develop a high vacuum in the tubing itself without a pump or releaser. [ MORE ]
