Why the Jar?

The spark to open Mason Jar occurred back in 2008. At the time, our founder Erin Mason was commuting 33 miles one way into the Warehouse District of Minneapolis, MN. She was neck-deep in food accounts and had just had her third child in three and a half years. Erin found the stop-and-go traffic provided time to think about owning the company she was managing and potential company names that would be memorable yet symbolic of what she wanted the company to stand for.


She wanted a name that would be symbolic of her hard-working mother and grandmothers; it was their generations that paved the path for Erin to confidently own and operate a business. She wanted the company name to symbolize characteristics important to providing an unmatched, creative experience. Transparent, versatile, innovative were just a few that came to mind. And finally, she wanted to make it easy for people to remember her and the name of her company. As a result, Mason Jar was chosen.
