As of May 2015, KetchupWorld.com, MyBrands.com, and Amazon.com sell Brooks Rich & Tangy Ketchup. A product locator from Pinnacle Foods, which owns the Brooks brand, shows the ketchup available in one Chicago store but in none within 30 miles of several other major cities.
CatsupBottle.com sells Brooks Rich & Tangy Ketchup and offers some history of the product. The ketchup brand originated in Collinsville, Illinois, now home of the world's largest catsup bottle. The largest ketchup bottle is actually a water tower standing 170 feet, built for the plant that once bottled Brooks ketchup and designed to look like a bottle of the product.
