The Board may issue a wine license privilege. To qualify for the privilege, an applicant shall be a holder of a Class B (on–sale) beer and wine license or Class B beer, wine, and liquor license for use on a premises that qualifies as a restaurant under § 24–902 of this title. The privilege authorizes the holder to sell wine by the bottle for off–premises consumption without the cost of the wine counting as a part of the average daily receipts of the business required to meet the minimum 60% food sales requirement under § 24–902 of this title. The privilege is not a separate class of license but is part of the existing Class B (on–sale) beer and wine license or Class B beer, wine, and liquor license of the holder of the privilege. The annual fee is $100.
