If you love Horehound candy, then you know all about Claelys! Claeys Candy was founded in 1919 in a garage by Jerome C. Claeys, grandfather of the current president, Gregg Claeys. The original location was a small building on Blaine Ave. As sales increased, larger buildings were required. The current plant on S. Taylor is the 4th plant that Claeys Candy has built.
