Drill into a maple tree, stick a tap in there, hang a bucket, and come back a few hours later, boom, sap.<\/p>\n<p>Now, if you are trying to make a lot of syrup, this is not the most efficient technique.<\/p>\n<p>This is much more efficient. sap from 50 to 150 trees flows down these blue tubes into this black mainline tube, and then collects here in this gigantic bucket.<\/p>\n<p><span id=\"ezoic-pub-ad-placeholder-116\" data-inserter-version=\"2\"\/><span class=\"ezoic-ad leader-2 leader-2116 adtester-container adtester-container-116 ezoic-ad-adaptive\" data-ez-name=\"scitechdaily_com-leader-2\"><span class=\"ezoic-ad leader-2 leader-2-multi-116 adtester-container adtester-container-116\" data-ez-name=\"scitechdaily_com-leader-2\"><span id=\"div-gpt-ad-scitechdaily_com-leader-2-0\" ezaw=\"290\" ezah=\"250\" style=\"position:relative;z-index:0;display:inline-block;padding:0;min-height:250px;min-width:290px\" class=\"ezoic-ad\"\/><\/span><span class=\"ezoic-ad leader-2 leader-2-multi-116 adtester-container adtester-container-116\" data-ez-name=\"scitechdaily_com-leader-2\"><span id=\"div-gpt-ad-scitechdaily_com-leader-2-0_1\" ezaw=\"290\" ezah=\"250\" style=\"position:relative;z-index:0;display:inline-block;padding:0;min-height:250px;min-width:290px\" class=\"ezoic-ad\"\/><\/span><\/span><\/p>\n<p>You can even hook up a vacuum pump to speed up the collection process and pull more sap out of the tree.<\/p>\n<p>Biology break. All plants use photosynthesis to produce glucose, which they then convert to sucrose, table sugar.<\/p>\n<p>They\u2019re not producing it for us. They metabolize it for energy. They turn some of it into cellulose to grow, and they turn some of it into starch to save for later.<\/p>\n<p>Now, photosynthesis generates sugar in the leaves, but plants need to transport it everywhere. And they do that by dissolving it in water, thus generating sap and moving that sap through vessels called phloem and xylem.<\/p>\n<p><span id=\"ezoic-pub-ad-placeholder-117\" data-inserter-version=\"2\"\/><span class=\"ezoic-ad small-square-2 small-square-2117 adtester-container adtester-container-117\" data-ez-name=\"scitechdaily_com-small-square-2\"><span id=\"div-gpt-ad-scitechdaily_com-small-square-2-0\" ezaw=\"336\" ezah=\"280\" style=\"position:relative;z-index:0;display:inline-block;padding:0;width:100%;max-width:1200px;margin-left:auto!important;margin-right:auto!important;min-height:280px;min-width:336px\" class=\"ezoic-ad\"\/><\/span><\/p>\n<p>(bell chiming)<\/p>\n<p>But wait a second. If all plants are doing this, why do we mostly make syrup from maple trees?<\/p>\n<p>Because maples are one of the few species of tree that exudes sap if you poke a hole into the trunk.<\/p>\n<p>Okay, but why do they do that?<\/p>\n<p>It\u2019s complicated. The short version is maples have air bubbles in the cells lining their xylem vessels. Most plants don\u2019t.<\/p>\n<p><span id=\"ezoic-pub-ad-placeholder-118\" data-inserter-version=\"2\"\/><span class=\"ezoic-ad leader-4 leader-4118 adtester-container adtester-container-118\" data-ez-name=\"scitechdaily_com-leader-4\"><span id=\"div-gpt-ad-scitechdaily_com-leader-4-0\" ezaw=\"300\" ezah=\"250\" style=\"position:relative;z-index:0;display:inline-block;padding:0;min-height:250px;min-width:300px\" class=\"ezoic-ad\"\/><\/span><\/p>\n<p>So when the temperature drops below freezing, those bubbles shrink and create negative pressure. When temperatures warm back up, the bubbles grow and you you get positive pressure.<\/p>\n<p>In the spring, when warm days follow below freezing nights, pressures in the xylem at the base of a tall maple tree can exceed 40 pounds per square inch.<\/p>\n<p>Drill a hole, stick a tap in there, and sap comes dripping out.<\/p>\n<p>Bill and I, mostly Bill and Sue, collected about 100 gallons of sap to turn into syrup.<\/p>\n<p>Now, the traditional way to maple syrup is to just take the sap and boil it.<\/p>\n<p><span id=\"ezoic-pub-ad-placeholder-119\" data-inserter-version=\"2\"\/><span class=\"ezoic-ad leader-3 leader-3119 adtester-container adtester-container-119\" data-ez-name=\"scitechdaily_com-leader-3\"><span id=\"div-gpt-ad-scitechdaily_com-leader-3-0\" ezaw=\"300\" ezah=\"250\" style=\"position:relative;z-index:0;display:inline-block;padding:0;min-height:250px;min-width:300px\" class=\"ezoic-ad\"\/><\/span><\/p>\n<p>Sap can be anywhere from one to 5% sugar. Usually, it\u2019s about 2%.<\/p>\n<p>Maple syrup, by law, has to be at least 66% sugar, 66.9 in Vermont and New Hampshire.<\/p>\n<p>Now, what\u2019s so special about 66% or 66.9%? Below 66, the syrup spoils more easily. And above 67%, the sugar starts to crystallize out. 66 to 67% is the Goldilocks Zone.<\/p>\n<p>When you buy maple syrup, you\u2019re expecting a product that won\u2019t spoil and won\u2019t crystallize. And the FDA is here to make sure you get it.<\/p>\n<p>The FDA\u2019s food labeling laws are how you know you\u2019re actually buying what you think you\u2019re buying.<\/p>\n<p><span id=\"ezoic-pub-ad-placeholder-120\" data-inserter-version=\"2\"\/><span class=\"ezoic-ad large-mobile-banner-2 large-mobile-banner-2120 adtester-container adtester-container-120\" data-ez-name=\"scitechdaily_com-large-mobile-banner-2\"><span id=\"div-gpt-ad-scitechdaily_com-large-mobile-banner-2-0\" ezaw=\"300\" ezah=\"250\" style=\"position:relative;z-index:0;display:inline-block;padding:0;min-height:250px;min-width:300px\" class=\"ezoic-ad\"\/><\/span><\/p>\n<p>Without them, anyone could produce a syrup that\u2019s only 50% sugar or 55% sugar for a lot less money, by the way, label it maple syrup, and legally sell it right next to a maple syrup that\u2019s 66% sugar.<\/p>\n<p>And the way you get your sugar content high enough is with the evaporator. This is where 2% sugar or sap becomes 66% sugar syrup.<\/p>\n<p>To get from 2% to 66%, you have to boil away a lot of water.<\/p>\n<p>Now the sap Bill and I collected was 1.8% sugar, which means that to make one gallon of maple syrup, we\u2019ll need 48 gallons of sap.<\/p>\n<p>That\u2019s a pretty wild ratio and explains why you need hundreds of maple trees and an efficient way to process all that sap to be a profitable maple syrup operation.<\/p>\n<p><span id=\"ezoic-pub-ad-placeholder-121\" data-inserter-version=\"2\"\/><\/p>\n<p>Modern evaporators like Bill and Sue\u2019s have multiple pans. All of which are heated by this massive wood stove. Fresh sap flows in here, and pushes the sap that was already in the evaporator forward along this circuitous path.<\/p>\n<p>And the sap becomes more and more concentrated as it flows since it\u2019s in contact with the heat for longer and longer. And like with many foods, heat is why the magic happens.<\/p>\n<p>Now, this is a really important point. Maple syrup, it is not just maple tree sap with a bunch of water removed, okay?<\/p>\n<p>Boiling the sap does way more than just concentrate the sugars.<\/p>\n<p>It drives all kinds of chemical reactions that turn maple syrup brown and give it its characteristic flavor. Specifically caramelization reactions and Maillard reactions.<\/p>\n<p><span id=\"ezoic-pub-ad-placeholder-122\" data-inserter-version=\"2\"\/><span class=\"ezoic-ad mobile-leaderboard-1 mobile-leaderboard-1122 adtester-container adtester-container-122\" data-ez-name=\"scitechdaily_com-mobile-leaderboard-1\"><span id=\"div-gpt-ad-scitechdaily_com-mobile-leaderboard-1-0\" ezaw=\"300\" ezah=\"250\" style=\"position:relative;z-index:0;display:inline-block;padding:0;min-height:250px;min-width:300px\" class=\"ezoic-ad\"\/><\/span><\/p>\n<p>Now, calling these reactions is technically accurate, but each one is really more like a book of reactions or an entire library of reactions or a large seafaring vessel stuffed to the brim with chemical reactions.<\/p>\n<p>I mean, just look at this general scheme of the Maillard reaction. Look at it. It\u2019s shaded, gray bubbles all over the place, shaded bubbles. What is this? Business school?<\/p>\n<p>Let me just tell you something. When chemists start using diagrams that look like a third grader made them in power\u2026<\/p>\n<p>(buzzer buzzes)<\/p>\n<p>Caramelization happens in all kinds of foods.

The denser a liquid is, the heavier it is per unit volume, the more it pushes up on the air-filled hydrometer, the higher it floats in the liquid.<\/p>\n<p>Nope, density is too low. So Bill bumps the temperature setting up a bit.<\/p>\n<p>Remember, the higher the concentration of sugar in water, the higher it\u2019s boiling point. So, by bumping the temperature point upward, Bill is basically saying to this valve, \u201cYou keep your trap shut until you hit a higher temperature,\u201d and thus a higher sugar content.<\/p>\n<p><span id=\"ezoic-pub-ad-placeholder-128\" data-inserter-version=\"2\"\/><span class=\"ezoic-ad netboard-2 netboard-2128 adtester-container adtester-container-128\" data-ez-name=\"scitechdaily_com-netboard-2\"><span id=\"div-gpt-ad-scitechdaily_com-netboard-2-0\" ezaw=\"468\" ezah=\"60\" style=\"position:relative;z-index:0;display:inline-block;padding:0;width:100%;max-width:1200px;margin-left:auto!important;margin-right:auto!important;min-height:90px;min-width:728px\" class=\"ezoic-ad\"\/><\/span><\/p>\n<p>Eventually, he hits a temperature that produces 66.9% maple syrup. And then we just collect.<\/p>\n<p>And by that, I mean, he collects while I watch uselessly and taste from little plastic shot glasses.<\/p>\n<p>Now, these shot glasses are completely optional, but let me tell you, that hot unfiltered maple syrup straight from the evaporator is one of the best things I\u2019ve ever tasted.<\/p>\n<p>Next, you filter the syrup and bottle it. Here\u2019s the three second musical montage of this process because this video is already entirely too long.<\/p>\n<p><span id=\"ezoic-pub-ad-placeholder-129\" data-inserter-version=\"2\"\/><span class=\"ezoic-ad mobile-leaderboard-2 mobile-leaderboard-2129 adtester-container adtester-container-129\" data-ez-name=\"scitechdaily_com-mobile-leaderboard-2\"><span id=\"div-gpt-ad-scitechdaily_com-mobile-leaderboard-2-0\" ezaw=\"250\" ezah=\"250\" style=\"position:relative;z-index:0;display:inline-block;padding:0;width:100%;max-width:1200px;margin-left:auto!important;margin-right:auto!important;min-height:90px;min-width:728px\" class=\"ezoic-ad\"\/><\/span><\/p>\n<p>(upbeat music)<\/p>\n<p>Boiling off 47 gallons of water to make one gallon of syrup, takes a long time and a lot of wood. And you have to do it pretty quickly after you collect all of the tree sap, which means that some seasons, you can be boiling till 3:00 am for days on end.<\/p>\n<p>And last year, my wife and I were in here for seven and straight days boiling.<\/p>\n[Host] That led Bill and Sue to do something they\u2019d been considering, but hesitant to do, buy a reverse osmosis or RO machine.<\/p>\n<p>And it just cuts way down on the boiling time.<\/p>\n<p><span id=\"ezoic-pub-ad-placeholder-130\" data-inserter-version=\"2\"\/><span class=\"ezoic-ad sky-3 sky-3130 adtester-container adtester-container-130 ezoic-ad-adaptive\" data-ez-name=\"scitechdaily_com-sky-3\"><span class=\"ezoic-ad sky-3 sky-3-multi-130 adtester-container adtester-container-130\" data-ez-name=\"scitechdaily_com-sky-3\"><span id=\"div-gpt-ad-scitechdaily_com-sky-3-0\" ezaw=\"290\" ezah=\"250\" style=\"position:relative;z-index:0;display:inline-block;padding:0;min-height:250px;min-width:290px\" class=\"ezoic-ad\"\/><\/span><span class=\"ezoic-ad sky-3 sky-3-multi-130 adtester-container adtester-container-130\" data-ez-name=\"scitechdaily_com-sky-3\"><span id=\"div-gpt-ad-scitechdaily_com-sky-3-0_1\" ezaw=\"290\" ezah=\"250\" style=\"position:relative;z-index:0;display:inline-block;padding:0;min-height:250px;min-width:290px\" class=\"ezoic-ad\"\/><\/span><\/span><\/p>\n<p>RO machines were originally invented to desalinate seawater, and they\u2019re used in chemistry labs around the world to make ultrapure water.<\/p>\n<p>RO systems are basically ultra high-pressure filtration systems.<\/p>\n<p>This line in the middle is a membrane with lots of super, super small holes, barely bigger than a water molecule. Here on the left, you\u2019ve got your tree sap, water with all those dissolved molecules. On the right, pure water.<\/p>\n<p>Then you apply massive amounts of pressure to the left side here, forcing water through the holes in the membrane. All the other molecules are too big to fit, so they stay on the left, which means what you end up with is much more concentrated sap.<\/p>\n<p>Now, in theory, you could concentrate the sap to 66% sugar but that would not produce maple syrup, because the RO barely heats the sap at all.<\/p>\n<p><span id=\"ezoic-pub-ad-placeholder-131\" data-inserter-version=\"2\" data-ezadblocked=\"true\"\/><\/p>\n<p>Bill and Sue use their RO to concentrate sap to about 8% sugar. Then they boil it the rest of the way.<\/p>\n<p>Now, starting with 8% sugar means they only need about 11 gallons of sap to make a gallon of maple syrup instead of 48. And that cuts down dramatically on the amount of wood they need to burn and the time the boil takes.<\/p>\n<p>But some traditional maple syrup producers were concerned that using an RO machine might affect the flavor of the syrup. So, researchers at the University of Vermont did a study in which they asked 46 lucky tasters to taste syrup produced using RO machines against syrup produced without RO machines.<\/p>\n<p>Of course, the tasters did not know which one was which. The tasters liked both syrups equally and rated the RO produced syrups as having characteristic maple syrup flavor.<\/p>\n<p>Essentially, using an RO system didn\u2019t make any discernible difference to the flavor.<\/p>\n<p><span id=\"ezoic-pub-ad-placeholder-132\" data-inserter-version=\"2\"\/><span class=\"ezoic-ad small-square-1 small-square-1132 adtester-container adtester-container-132\" data-ez-name=\"scitechdaily_com-small-square-1\"><span id=\"div-gpt-ad-scitechdaily_com-small-square-1-0\" ezaw=\"250\" ezah=\"250\" style=\"position:relative;z-index:0;display:inline-block;padding:0;width:100%;max-width:1200px;margin-left:auto!important;margin-right:auto!important;min-height:90px;min-width:728px\" class=\"ezoic-ad\"\/><\/span><\/p>\n<p>More studies since then have been done to confirm that result.<\/p>\n<p>But since this is a relatively small batch we\u2019re making here today, we are gonna do it the old-fashioned way.<\/p>\n<p>This is now officially maple syrup. And you can\u2019t see the color too well here, but when Bill eventually grades this, he\u2019ll find that it\u2019s Grade A amber color with a rich taste.<\/p>\n<p>So where\u2019s my Grade B?<\/p>\n<p>While the FDA regulates what can legally be sold as maple syrup, it\u2019s the USDA that provides guidance on grading.<\/p>\n<p><span id=\"ezoic-pub-ad-placeholder-133\" data-inserter-version=\"2\"\/><span class=\"ezoic-ad portrait-1 portrait-1133 adtester-container adtester-container-133\" data-ez-name=\"scitechdaily_com-portrait-1\"><span id=\"div-gpt-ad-scitechdaily_com-portrait-1-0\" ezaw=\"336\" ezah=\"280\" style=\"position:relative;z-index:0;display:inline-block;padding:0;width:100%;max-width:1200px;margin-left:auto!important;margin-right:auto!important;min-height:280px;min-width:336px\" class=\"ezoic-ad\"\/><\/span><\/p>\n<p>Now, grading syrup is actually optional in most states, but in Vermont and a couple other states, you are required to, because Vermont takes their maple syrup seriously.<\/p>\n<p>Grading is partly about darkness of the syrup, or to be more precise, percent transmittance of 560 nanometer wavelength light through a 10 millimeter sample of syrup. Which means, if you shoot a beam of this color light through 10 millimeters of maple syrup, and 75% or more of it makes it through the syrup, then you\u2019ve got yourself the lightest possible grade of syrup.<\/p>\n<p>Which before 2015, was legally allowed to be called Vermont Fancy, Ohio Grade A Light Amber, or Grade A Light Amber.<\/p>\n<p>If a syrup transmits between 27 and 43.9% of this light, then you\u2019ve got yourself a syrup, which before 2015 was legally allowed to be called Grade B in Vermont, Grade B finally, Extra Dark for Cooking in New York or Grade B for Reprocessing in most other states.<\/p>\n<p>Now, imagine you\u2019re a tourist in Vermont and you see two bottles of maple syrup on the shelf. One says, \u201cVermont Fancy.\u201d And the other says, \u201cGrade B,\u201d which are you gonna assume is better?<\/p>\n<p><span id=\"ezoic-pub-ad-placeholder-134\" data-inserter-version=\"2\"\/><span class=\"ezoic-ad small-rectangle-1 small-rectangle-1134 adtester-container adtester-container-134\" data-ez-name=\"scitechdaily_com-small-rectangle-1\"><span id=\"div-gpt-ad-scitechdaily_com-small-rectangle-1-0\" ezaw=\"728\" ezah=\"90\" style=\"position:relative;z-index:0;display:inline-block;padding:0;width:100%;max-width:1200px;margin-left:auto!important;margin-right:auto!important;min-height:90px;min-width:728px\" class=\"ezoic-ad\"\/><\/span><\/p>\n<p>Vermont Fancy, obviously.<\/p>\n<p>But here\u2019s the thing. A lighter color does not mean the syrup is better. Light and dark syrups have different taste profiles. Light syrup has a delicate maple flavor. Darker syrups have more caramel, caramel, toffee and coffee notes, in addition to the characteristic maple flavor.<\/p>\n<p>In 2014, the International Maple Syrup Institute petitioned the USDA to rename the grading standards, partly because of the Grade A, Grade B issue, which they did in 2015.<\/p>\n<p>So these days, there are four types of Grade A syrup, Golden-Delicate, Amber-Rich, Dark-Robust and Very Dark-Strong.<\/p>\n<p>The words before the dash refer to the color, and the words after it refer to the flavor.<\/p>\n<p><span id=\"ezoic-pub-ad-placeholder-135\" data-inserter-version=\"2\"\/><span class=\"ezoic-ad sky-4 sky-4135 adtester-container adtester-container-135\" data-ez-name=\"scitechdaily_com-sky-4\"><span id=\"div-gpt-ad-scitechdaily_com-sky-4-0\" ezaw=\"336\" ezah=\"280\" style=\"position:relative;z-index:0;display:inline-block;padding:0;width:100%;max-width:1200px;margin-left:auto!important;margin-right:auto!important;min-height:280px;min-width:336px\" class=\"ezoic-ad\"\/><\/span><\/p>\n<p>There\u2019s no Grade B anymore.
