Some Maine maple syrup producers are starting their tree tapping season over a month ahead of schedule due to warmer temperatures this winter, according to CBS 13.

Maine was the third largest producer of maple syrup in the U.S. last year and is expected to maintain that position as the past decade of warmer temperatures have pushed Maine’s tapping seasons earlier and earlier.

While tapping trees earlier in the year doesn’t appear to have any adverse effects, a maple tree can only create so much sap before it starts budding, causing some producers to hold off on production until the usual tapping season. The sap being produced currently will likely have a lower sugar content than it normally would in March, when big temperature swings create higher sugar content.

Higher sugar content will have no effect on maple syrup’s taste; however, it will take more than the usual 40 gallons of sap to boil down to a gallon of syrup.
