The bill establishes a Winery Co-marketing Grant Program under the Department of Agriculture, aimed at reimbursing New Jersey wineries for eligible marketing campaign costs. The program is designed to promote agricultural tourism and support local businesses by allowing wineries to engage in co-marketing efforts with other entities, such as restaurants, hotels, and roadside markets. Eligible applicants must hold a plenary or farm winery license and can apply for grants once a year, with awards of up to $25,000 based on the number of entities involved in the marketing campaign.

Additionally, the bill mandates the Secretary of Agriculture to submit annual reports to the Governor and Legislature regarding the program's implementation and effectiveness. These reports must detail the total number and dollar amount of grants awarded, provide recommendations for the program's continuation, and identify any unspent funds available for future grants. The bill appropriates $500,000 from the General Fund to finance these reimbursement grants and requires the Department of Agriculture to adopt necessary regulations for the program's implementation.
