(a) This section applies to a Class 7 micro–brewery license in the City. (b) The license may be issued only to the holder of: (1) a Class B beer, wine, and liquor (on–sale) license that is issued for use on the premises of a restaurant located in the City; or (2) a Class D alcoholic beverages license that is issued for use on the premises of the existing Class D license located in the 40th alcoholic beverages district of the City. (c) (1) Subject to paragraphs (2), (3), and (4) of this subsection, the holder of a Class 7 micro–brewery license may: (i) brew in two locations using the same Class 7 micro–brewery license; and (ii) obtain a Class 2 rectifying license for the premises at the two locations authorized under item (i) of this paragraph. (2) The holder of a Class 7 micro–brewery license may brew in two locations using the same Class 7 micro–brewery license if the license holder: (i) requests permission by submitting a written application to the Executive Director; and (ii) obtains written approval from the Executive Director. (3) Before authorizing a holder of a Class 7 micro–brewery license to brew in two locations using the same Class 7 micro–brewery license, the Executive Director shall: (i) make a determination that a second location to brew additional capacity is necessary due to insufficient space at the existing Class 7 license location; and (ii) consider any other factor relevant to approval of the application. (4) Notwithstanding any other provision of this article, a holder of a Class 7 micro–brewery license may not serve or sell beer for on– or off–premises consumption at the second brewing location authorized under this subsection.
