Skrewball, officially known as Skrewball Peanut Butter Whiskey, is a brand of American whiskey liqueur that has gained widespread popularity for its unique and unconventional flavor. The brand was founded by Steven and Brittany Yeng in Ocean Beach, California. Steven, a Cambodian refugee, developed a love for peanut butter after receiving it in care packages upon his family's arrival in the United States. He later created a peanut butter and whiskey shot at his restaurant, which became a local sensation. His wife, Brittany, a chemist, helped him transform the concoction into a shelf-stable, bottled spirit.

The brand's identity is built on this "screwball" or unconventional idea, celebrating the spirit of being a "black sheep." This ethos is reflected in their logo and their marketing, which encourages consumers to "skrew the usual." The whiskey is praised for its balance of sweet and savory notes, with a rich, creamy peanut butter flavor complemented by the warmth of whiskey.

Skrewball's rapid growth and success led to its acquisition by Pernod Ricard in 2023, a move that brought the brand under the umbrella of one of the world's largest spirits companies. Despite this change in ownership, the brand maintains its rebellious, fun-loving image and continues to appeal to both traditional whiskey drinkers and those new to the category.
