(a) Each winery in this state shall keep records to establish the quantity of grapes, berries, fruits, or vegetables grown in this state which are purchased and used for the making of wine in this state.
(b) The records shall include weight receipts for fruits and vegetables, together with proof of purchase of the fruits and vegetables from Arkansas producers, a copy of which shall accompany requests for a tax subsidy payment.
