MADISON, Wis. (AP) -- A new state law affecting Wisconsin wineries takes effect on Wednesday.
The law requires all wineries to use wholesalers unless they sell directly to a consumer or make less than 25,000 gallons a year and go through a cooperative.
Some small wineries are forming cooperatives to keep their wines on the shelves of grocery and liquor stores.
The Legislature passed the law earlier this year.
It was in reaction to a 2005 U.S. Supreme Court ruling that said states can't discriminate between in-state and out-of-state wineries.
Currently, Wisconsin requires wineries to sell through wholesalers only if they are based outside of Wisconsin.
