Foodies celebrate all things fizzy and foamy at the inaugural Ferment Fest. Local vendors sell and offer samples of their lip-smackingly sour wares, including coffee, wine, beer, yogurt, sauerkraut, cheese, kimchi, mead and kombucha. Attendees learn more about the art and science of fermentation from a lineup of speakers; exchange sourdough starters, kombucha SCOBYs, vinegar mothers and kefir grains at the community swap; and enjoy the tangy, briny tunes of the Dirty Forks while snacking on cheese boards and sourdough doughnuts.
