Rob Heater tests the carbonation of Tripel Ale at Allagash Brewing. The company made 2,865,584 gallons of beer in 2016, second in Maine only to Shipyard.
Barrels are labeled with names and dates. Allagash recently added four new fermenters, each with the capacity to make about 16,740 gallons of beer per batch.
Tripel ale is packaged at Allagash's Portland facility. The biggest quantity of beer Allagash sells is a four pack, while most national brewers market 12 and 24 packs.

Shipyard brewer Dan McLean glances out the brewery window during a pause in the process. Shipyard produced 3,658,571 gallons of beer in 2016.
Shipyard, Maine's No. 1 producer of beer by volume, shows a sense of humor with a sign above a vat of fermenting beer.
A conveyor moves empty boxes to be filled with Sea Dog beer on Shipyard Brewing's packaging floor. Shipyard serves as a contract brewery for several local brands.
