Flounder Brewing Company is a microbrewery in Hillsborough in Somerset County, New Jersey.

[1][2] Started by Jeremy Lees as a homebrewing hobby, it grew to encompass other members of the family including his brothers, Daniel and Michael, and his cousin William.

The expansion included adding a 15 barrel brewhouse and now features a 100 person capacity tasting barn with mezzanine as well as two outdoor beer gardens.

There are currently two seasonal releases in the rotation – Floundering Pumpkin in the fall based, a spiced pumpkin amber ale, and the Gingerbread Brown, a spiced brown winter ale.

[3][5] Flounder has a limited brewery license from the New Jersey Division of Alcoholic Beverage Control, which allows it to produce up to 300,000 barrels of beer per year, to sell on-premises as part of a tour, and to distribute to wholesalers and at festivals.
