They produced beer and ales under the Holihan's and Diamond Spring labels.
Their firm carried a general line of liquors, including two brands they claimed as proprietary, “Banquet Pure Rye” and “Old 56,” the latter presumably for the year their father and his brother had founded the business.
In 1912, the three Holihan sons, James, Joseph and Charles, opened a brewery on land purchased near the corner of Andover and Beacon Streets in South Lawrence.
In 1917, they branched into soft drinks using the spring water as a base.
