A St. Patrick’s Day Story by Guinness x Carhartt | Guinness Beer

From Guinness x Carhartt: Ever wonder who runs Chicago’s St. Paddy’s Day Parade? Here’s to the people behind the greatest St. Patrick’s Day Parade on Earth, including the Plumbers from The Chicago Journeyman Plumbers Local Union 130. Made up of over 6,100 members, they’ve been dyeing the Chicago River green since 1962. Note: since 1966, an eco-friendly vegetable-based dye has been used to create the iconic green color of the Chicago River on the day of the St. Patrick’s Day Parade. While the contents of the dye remain a closely guarded secret, it has been approved by the city of Chicago, as it has been thoroughly tested and deemed safe for all aquatic wildlife and plants.
