Not even the 100-degree temperatures can deter hot sauce lovers from gathering at Fiesta Gardens each August for the Austin Chronicle Hot Sauce Festival.

This year is no different. We're in the middle of a major heat wave that will likely take us into September without a break, but 11 a.m. to 5 p.m. on Sunday, thousands of hot sauce lovers will gather at Fiesta Gardens, 2101 Jesse E. Segovia St., to try dozens of hot sauces, listen to live music and enjoy one of the longest-running food events in Austin.

This is the 29th year for the Hot Sauce Festival, which started as a small gathering in 1990. The event is free to attend with a $5 suggested donation to the Central Texas Food Bank. The event has raised more than 875,000 meals for the food bank since it started. This year's musical guests include Bruce Robison and Kelly Willis, Harry Edohoukwa, Mariachi Capitál and Batty jr.

Food trucks including Amy's Ice Creams, Garbo's Lobster Truck ATX, Johnny Joe’s Concessions, Sauce Odyssey, Sun Garden Shaved Ice, Torchy's Tacos and Ze Wurst will serve food for sale, but attendees can also sample and buy hot sauce from dozens of vendors.
