PLAINFIELD, MASS. >> Massachusetts maple syrup producers have had a second consecutive record-breaking year.

The Massachusetts Maple Producers Association announced Tuesday that according to federal statistics the state produced 77,000 gallons of syrup in 2016, 2,000 gallons more than 2015's record-setting yield.

Massachusetts ranks eighth among 13 maple syrup-producing states. Vermont led the nation with nearly 2 million gallons produced.

The primary reasons for the production increase were a long season and a relatively warm winter punctuated by deep freezes in February and March that kept the sap running.

Also, Massachusetts producers added 5,000 taps in 2016 and many have increased efficiency by installing modern equipment and adopting sustainable practices that help boost yield.

The state has more than 250 producers who tap more than 300,000 trees.
