If you’re not keyed into the local food and beverage industries, you might not have heard about this weekend’s biggest event celebrating all things comestible: Slow Food Nations, a three-day food festival that takes over Larimer Square July 19-21. Slow Food USA, which has chapters in cities across the U.S. and beyond, wants to “inspire individuals and communities to change the world through food that is good, clean and fair for all,” according to the organization’s website.
