ShareThis California Campus Culinary Demonstrations Calendar Public cooking demonstrations take place at 1:30 p.m. on most weekends throughout the year. Tastings of the recipe prepared will be paired with a taste of Greystone Cellars wine (served to guests 21 years of age or older). A non-alcoholic option will be provided as well. Tickets are $25 and are available for purchase in advance online and in the Spice Islands Marketplace on the day of the demonstration. Two children under the age of 12 are admitted at no charge when accompanied by a paying adult. Learn more about CIA's weekend cooking demonstrations.
