History
Ipswich Brewing Company, founded in 1991 by Paul Sylva and Jim Beauvais, encompassed an initial product line of Ipswich Ale and Dark Ale, introduced on draft, in 64 fl oz growlers, and in 1-liter swing tops. Rob Martin takes Ipswich’s Mercury Brewing Company to the next level with some sweat equity and a love for beer. The product line was extended in 1995 with the addition of Ipswich IPA and Oatmeal Stout. All styles were introduced in 12 fl oz bottles. Ipswich 1722 Commemorative Porter was introduced in 1996.In 1997, Ipswich Brewing Co. formed an alliance with United States Beverage for sales and marketing support and introduced Ipswich Winter Ale. Ipswich Brand was purchased by United States Beverage in 1999 but kept the brewery separately owned and operated.The product line was further extended in 1998 with Porter, Nut Brown, and Ipswich Ale Mustard. All packaged product was contracted by Clipper City Brewing Co., in Baltimore, MD.
