Butter interests in the state of Wisconsin are forcing out the competition with a “butter grading” law, and Kerrygold consumers are fuming all over social media. A Kerrygold butter seller in Wisconsin can be subject to a fine of $1,000 or 6 months in jail.
The issue here is an obscure state law from the 1970s that requires all butter sold in Wisconsin to be tested by a panel of experts and issued a letter grade for quality.
As a butter made in Ireland, Kerrygold is not graded in the U.S.
