Bus. & Prof. Code, § 25503.41

(a) Notwithstanding any other provision of this division, any person that both operates a winery in another state and produces distilled spirits in another state may hold an interest in no more than 12 brewpub-restaurant licenses, provided that all of the following conditions are met:

(1) The out-of-state distilling operations occur only on premises where the licensee also conducts brewpub-restaurant operations, and do not exceed 12,000 gallons of distilled spirits annually at any licensed location.

(2) The out-of-state winery operations occur only on premises where the licensee also conducts brewpub-restaurant operations.

(3) The distilled spirits and wine that are manufactured out of state by the licensee are not imported into or sold in this state. If the licensee imports beer into this state that is produced in its out-of-state brewpub, it shall do so only through a licensed beer and wine wholesaler.

(b) The Legislature finds that it is necessary and proper to require a separation between manufacturing interests, wholesale interests, and retail interests in the production and distribution of alcoholic beverages in order to prevent suppliers from dominating local markets through vertical integration and to prevent excessive sales of alcoholic beverages produced by overly aggressive marketing techniques. The Legislature further finds that the exception established by this section to the general prohibition against tied interests must be limited to its expressed terms so as not to undermine the general prohibition, and intends that this section be construed accordingly.
