Cal. Bus. & Prof. Code § 25503.33

(a) Notwithstanding any other provision of this division, a beer manufacturer or winegrower may provide sponsorship funds for or on behalf of a retail on-sale licensee provided each of the following conditions are met:
1. (1) The on-sale licensee is the owner and manager of outdoor fairs in northern and southern California which have a history-based theme and operate for 6 to 12 weekends in either or both venues and, excluding rain-outs, have an average daily attendance exceeding 10,000 persons.
2. (2) The sponsorship funds will be provided and used only in connection with specific programs or activities at the outdoor fairs described in paragraph (1).
3. (3) The sponsorship funds are to sponsor the following programs or activities only:
  1. (i) Signing program for the deaf.
  2. (ii) Docent program for the disabled.
  3. (iii) Public school history program.
  4. (iv) Scholarships and honoraria for the students of the College of Performing Arts.
  5. (v) Contests involving sports, cooking, brewing, costumes, and other skills related to arts and sciences.
  6. (vi) Equestrian exhibits and tournaments.
4. (4) The on-sale licensee serves other brands of beer or wine in addition to the brand manufactured by the beer manufacturer or produced by the winegrower providing sponsorship funds.
(b) Any provision of sponsorship funds pursuant to subdivision (a) shall be conducted pursuant to a written contract entered into by the beer manufacturer or winegrower and the on-sale licensee.
(c) Any beer manufacturer or winegrower who, through coercion or other illegal means, induces a beer or wine wholesaler to fulfill those contractual obligations entered into pursuant to subdivision (a), is guilty of a misdemeanor and is punishable by imprisonment in a county jail not exceeding six months, or by a fine in an amount equal to the entire value of the sponsorship funds involved in the contract, plus ten thousand dollars ($10,000), or by both that imprisonment and fine. This person shall also be subject to license revocation pursuant to Section 24200.
(d) 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 express terms so as not to undermine the general prohibition, and intends that this section be construed accordingly.
