Some Kansas winery owners are concerned about a new state law that cuts the percentage of Kansas-grown ingredients that wineries are required to have in their products.

The new law went into effect in May and cuts the amount of Kansas products required in Kansas wine from 60 percent to 30 percent. The new provision applies to a winery’s overall products, rather than each bottle. Under the law it would be acceptable, for example, for a winery to make one type of wine using 100 percent Kansas grapes and two other types with no Kansas grapes.

The Lawrence Journal-World reports supporters say lessening restrictions promotes growth of Kansas wineries.

Opponents say fostering regionality in the wine is more important than spurring large numbers of new wineries.
