LOWELL, Mich. (WZZM) -- Local land owners are welcoming the cold weather a little more than most this spring.

Ned Stoller, who's been making maple syrup since his childhood explained; "When everybody else is wishing spring would get here in April, and we get a snowstorm, we're all happy about that because it means another cold snap."

Slightly above freezing days and below freezing nights mean the sap of trees runs slowly. But decades of study have shed little light on the mystery of maple syrup.

Stoller said, "Essentially the trees are pulling moisture up to bud and produce leaves and have another growing season and that's what we're tapping into."

But most trees don't feed their leaves by this method. The Acer species (more commonly known as maples) is one of the very few in the world that can produce the sugary staple.

Stoller's happy about the yield so far. "This has been a good year, not because we've had a lot of sap. But because the sap is so sweet! On a typical year, we figure it takes 40 gallons of sap to make one gallon of maple syrup. And this year, it's only taken 27 to 30."

But, production is expected to wind down with the next warm spell...

"When the trees bud, the sap gets bitter and you can't make syrup. Well, you can but it tastes horrible," Stoller commented.
