Mr. Boston Liqueur Blue Curacao

The liqueur has an orange-like flavour with varying degrees of bitterness. It is naturally colourless, but is often given artificial colouring, most commonly blue or orange, which confers an exotic appearance to cocktails and other mixed drinks.
Mr. Boston distillery was founded in the Roxbury, Massachusetts neighborhood of Boston in 1933 by Irwin "Red" Benjamin and Hyman C. Berkowitz. Old Mister Boston was known for its collectible bottles such as the 1953 Presidential Inaugural Bottle.\nOver time, through a series of changes of ownership, the words "Old" and "Mr." were dropped from the name until it was known simply as "Boston."The distillery was a major employer in the Boston area from the 1930s until its closing circa 1986 when the parent company, Glenmore Distillers, shut down operations and the brand vanished. The building that housed Old Mr. Boston's operations is now owned by the City of Boston and is in use appropriately as a City Inspectional Services headquarters.\n
