Skrewball Peanut Butter Whiskey started a few miles from our shop, in Ocean Beach, San Diego, where founders Steven and Brittany Yeng first served a peanut-butter whiskey shot at their bar before bottling it in 2018. It became one of the fastest-growing spirits in the country: a 70-proof blend of whiskey and real peanut butter flavor that tastes like the inside of a peanut butter cup. Take it as a chilled shot, pour it over ice, or mix it with chocolate liqueur, cold brew or a stout. Shop Skrewball at Chips Liquor with fast shipping.
