WISCONSIN resident Jean Smith snatches up entire stocks of her beloved Kerrygold Irish butter from stores when visiting family in Nebraska, thanks to an antiquated law in her dairy-obsessed state that bans it and any other butter that hasn’t been graded for quality.

    “We bring back 20 bricks or so,” Smith said, noting she plops a tablespoon of the Ireland-made butter into her tea each morning.

    Tired of trekking across state lines to stock up, she and a handful of other Wisconsin butter aficionados filed a lawsuit this week challenging the law, saying local consumers and businesses “are more than capable of determining whether butter is sufficiently creamy, properly salted, or too crumbly.”

    On the books since 1953, the law is strict: It requires butters to be rated on various measures — including flavor, body and color — by the federal government or people licensed as butter and cheese graders with the Wisconsin Department of Agriculture, Trade and Consumer Protection.
