Gruesome Brew Coffee, run by Lord Gruesome (James Gillis) and Lady Gruesome (Jenny Gillis), who are small-batch, veteran-owned gourmet coffee roasters based in New Hampshire near Lake Winnipesaukee,

The couple started the business after leaving their post office jobs and spending a long time perfecting their flavors, often using customers as "guinea pigs". Their coffee is known for its themed lines, including **Cryptid**, **Alien**, **Myths and Monsters**, and **True Crime**, with flavors like the unflavored Mothman Mocha and Bigfoot Maple. They emphasize selling the freshest coffee possible, roasting daily and only grinding to order, which they did on-site at their first convention, the Maine Paranormal and Horror Convention. The couple travels to locations associated with their themes, such as planning a trip to Germany and Austria for the Krampus Run to get insight for their Krampus coffee, and they are also looking to expand their offerings into teas and themed candies like hot chocolate and chocolate-covered espresso beans.
