Real maple syrup costs more because there's very little sugar in maple sap, and turning sap into syrup takes a lot of time and heat. On average, it takes 40 gallons of sap to make one gallon of syrup, and the sap only runs for a few weeks a year, when the weather cooperates.
The Vermont Maple Sugar Makers' Association says it plainly: maple syrup is generally more expensive than other sweeteners. If you're weighing a switch from pancake syrup, here's where that cost comes from.
The short answer
- Sap is mostly water. It takes a lot of sap to make a little syrup, and a tap only gives so much.
- The season is short. Four to six weeks a year, and the weather is in charge.
- Boiling takes time and fuel. The sap has to be boiled down, and the heat isn't free.
- Trees take decades. A maple needs to be about 40 years old before it can be tapped.
Sap is mostly water
Maple sap is mostly clear water with about 2 percent sugar. Turning sap into syrup means nearly all of that water has to go. At the average of 40 gallons of sap to one gallon of syrup, a 16 fl oz tin starts out as about 5 gallons of sap.
Each tap only gives so much. A typical tap yields about 5 to 15 gallons of sap in a season. In 2026, Vermont's taps averaged about 0.38 gallons of syrup each for the whole season, according to the USDA. That's roughly 48 fluid ounces, or about six of our 8 fl oz tins, from one tap in one year. Vermont, the biggest producer, made about 3.1 million gallons that year from about 8.2 million taps.
The season is short, and the weather is in charge
A typical sugaring season lasts four to six weeks. Sap only flows when nights freeze and days warm to at least 40 to 45°F, and sugar makers have that short window to bring in their whole crop for the year.
Nobody gets to pick the weather. Timing can vary a lot from one sugarbush (a grove of maples tapped for sap) to the next, even in a state as small as Vermont. If a sugarbush stays too cold, the thaws might not be enough to get the sap flowing. If it's too warm, the season can end without warning. A USDA Forest Service resource notes that tough conditions can mean low-yield years and an unsteady supply of syrup.
Even last summer counts. The same resource says warmer summers have been linked to less sugar in the next spring's sap, and sweeter sap is what keeps the sap-to-syrup ratio down.
Boiling takes time and fuel
Sap can't wait around. The University of Maine compares it to milk: it sours if it sits in the sun, so it should be kept cold and boiled as soon as possible.
Sugar makers boil sap in an evaporator, a set of stainless steel pans over a firebox. Many producers run their sap through reverse osmosis first, which removes some of the water so it takes less time and energy to boil. The rest is boiled off with heat that has to be paid for: wood, oil, wood chips, wood pellets or electricity.
Ours is boiled over a wood-burning fire, and sugar makers who use wood stay busy splitting and stacking it in the off-season. Finishing takes care, too. Syrup is done at about 7°F above the boiling point of water, and after that it still has to be filtered, graded and packed hot.
It's a long game
You can't plant a maple and tap it next spring. A tree needs to be about 40 years old before it's big enough to tap. If a bad year or a storm takes out trees, a sugar maker can't just grow another row.
The work runs all year, too: managing the forest, pulling spouts, replacing tubing and cleaning equipment. The association lists science, forestry, equipment maintenance, food safety and business management among the skills it takes.
What that means for your tin
That's also why some syrup on the shelf costs less. If a bottle says pancake syrup or table syrup, check what it's made of. Pancake syrup is usually flavored corn syrup, a different product made without the sap, the season or the boil. Our guide to pure maple syrup vs. pancake syrup explains the difference.
Ours has one ingredient. The front of the tin says "100% pure maple syrup," and all of it is from a single Vermont forest, never blended. Pick Amber or Dark, in 8 fl oz or 16 fl oz tins.
