When to Tap

Experts say the best time to tap your tree is at the start of spring, which falls on March 20, 2023. However, because sap and syrup production in Michigan are weather-dependent you may need to wait longer.

The best times to tap your trees are when nighttime temperatures are below freezing but daytime temperatures are above freezing. The range of 20-40 degrees seems to be about perfect for production.

According to Pure Michigan,

This see-saw effect of warm days and cold nights causes pressure changes within the trees. If the tree’s internal pressure is greater than the external barometric pressure, sap will be pushed out of a hole drilled into the tree

Which Trees Produce Syrup?

Maple syrup is only made in North America where the preferred syrup tree, the Sugar Maple, thrives. This tree, which is the preferred tree for this type of sap collection, is found mainly in the Northeastern portion of the country and in southeastern parts of Canada which range from Ontario to Quebec.

The Michigan DNR says black, red, and silver Maple trees can also be tapped for syrup production, but the Sugar maple has the highest sugar to water ratio of 40:1 which is why it's often used in commercial syrup production.

How to Tap

The Michigan DNR has certain guidelines when it comes to tapping a tree for syrup production. For example, a tree must be at least 10 inches in diameter before it can be tapped.

Sap should also be kept cool and be processed as soon as possible to avoid spoilage. One tree can be expected to put out between 6-10 gallons of sap a season but be advised, it takes about 40 gallons of sap to make one gallon of syrup!


You'll know syrup-making season is over when your tree buds begin to open. You'll want to be sure to pull your taps at this time as the flow of sap will slow down and it will turn a yellow-ish color with a bitter taste. Bitter syrup? No thank you!

Back in February when we had that rare warm-up I saw a few trees along my commute that had already been tapped! It was short-lived now that the cold is back, but it's a sign that maple syrup making season is right around the corner.
