35 Miss. Code R. § 2-05-02-101
A holder of a Class 3 Native Wine Manufacturer's Permit shall be allowed to import bulk and/or fortified wines into this state for use in blending with native wines. In addition, permit holders shall make available to the Department or its representatives all records required by the Federal Government, showing the volume of bulk and/or fortified wines imported for blending or fortifying purposes. The Department shall satisfy itself that the volume of the wines imported does not exceed the volume the permit holder would reasonably be expected to produce from grapes planted in his vineyard, taking into consideration that fifty-one percent (51%) of the wine must be produced from grapes, fruits, berries, honey or vegetables grown and produced in Mississippi.
