Clint and Karen Underwood launched Inconceivable Coffee Roasters’s online store in January. The online business offers whole-bean coffee, mugs and apparel for purchase as well as customized grinds. Customers can choose from coffees roasted in Tomball, including three blends and three single-origin coffees, Clint said. The business ships coffee directly, and the couple hopes to open a brick-and-mortar location in the future, he said. www.inconceivablecoffee.com
