Waucoma Bookstore and Gorge Grown are hosting author Tara Whitsitt for a book signing on Saturday, Sept. 30 from 9 a.m. to 1 p.m. at the Hood River Farmers’ Market, Fifth and Columbia streets in downtown Hood River.

Whitsitt will be signing her new book, “Fermentation on Wheels: Road Stories, Food Ramblings, and 50 Do-It-Yourself Recipes from Sauerkraut, Kombucha, and Yogurt to Miso, Tempeh, and Mead.” Whitsitt will also have her bus-turned-fermentation lab at the event. The public is invited on the bus for tours, tastings, and fermentation talk. Bring starter cultures of your own for exchange and discussion, added a press release. (If you would like to take a starter culture home with you, please bring something to trade or $10 per starter culture.)
