This bill amends New Jersey's winery licensing laws to allow certain winery license holders to sell wine produced by other wineries under specific conditions. It introduces a supplemental wine production facility sublicense, enabling holders of plenary or farm winery licenses to produce wine at an additional facility they own or lease, provided it is operated by them. The bill specifies that wine sold to other wineries will not count towards the seller's production total but will be included in the purchasing winery's annual production calculations. Additionally, it mandates that at least 50% of the wine sold by a winery each year must be produced on their licensed premises.

The legislation also modifies existing definitions and privileges associated with various winery licenses, including plenary and farm winery licenses. It establishes a fee of $750 for obtaining the supplemental wine production facility sublicense and clarifies the requirements for winery license holders, including stipulations about the production of wine and the use of alternating proprietorship agreements. The bill includes various amendments to the language of existing laws, ensuring clarity in the definitions and activities permitted under these licenses.
