Three Centuries of Molasses in Massachusetts

The molasses trade has a long and sticky history in Massachusetts. Though sugar is far more common in the kitchen cupboard today, molasses lingers in the cultural lore of Boston. Looking back over that tradition one sees how far back those roots go. In a letter to Judge William Tudor on 11 August 1818 John Adams credited molasses as helping usher in American independence:

Witts may laugh at our fondness for Molasses & we ought all join in the laugh with as much good humour as General Lincoln did, Genal Washington however always asserted & proved that Virginians loved Molasses as well as New Englandmen did. I know not why we should blush to confess that Molasses was an essential Ingredient in American Independence. Many great Events have proceeded from much smaller causes.

How could the secret ingredient in pot roasts have influenced the course of history in Massachusetts and the nation? In the 18th century, the Sugar Islands experienced an exponential demand for sugar from European colonizers. There was profit not only in sugar but in distilling the by-product of sugar production, molasses, into rum. The abundance of molasses gave rise in part to the ‘Triangle Trade’ exchange: New England rum to West Africa and Europe, West African slaves to the Sugar Islands, and Sugar Islands’ molasses to New England rum distilleries. With the Molasses Act of 1733 Great Britain imposed a tax on molasses imported from foreign colonies, such as the French or Dutch West Indies. Some point to this act as the stirrings of the beginning of the American Revolution, as the tax struck fear in the northern colonies by affecting their rum trade.

Oh, the rum! With incoming shipments of Sugar Islands’ molasses, Massachusetts entertained a booming rum industry. There were over 25 distilleries in Boston alone by the mid-eighteenth century. The surrounding cities, including Watertown, Haverhill, Charlestown, and Medford soon followed the “city upon a hill” into rum distillation.

Then, nearly a century after Adams wrote to Judge Tudor molasses literally engulfed part of Boston. Yesterday marked the 94th anniversary of the great Boston molasses flood, affecting Commercial Street in the North End on 15 January 1919. It was on this unusually warm day that the US Industrial Alcohol/Purity Distilling Company tank filled with 2,300,000 gallons of molasses spilled into the streets and harbor. The flood killed 21 individuals and injured more than 150 others while damaging an estimated $100,000,000 of property. The 1919 tragedy inundated the newpapers with conspiracies and conjecture about how the tank had failed so epically. It is said that even now it is not uncommon to hear that on a hot summer day there is a lingering scent of molasses in the North End.

Thank you for this great informative article on molasses and its importance in our trade history! Have you read The Dark Tide by Stephen Puleo? It is about the great molasses flood-a good read.
