UC Davis threw a party last week for the campus's very own olive oils, vintage 2007. The oil is made from the fruit of the campus's 1,500 olive trees. They have been around for years, but it was not until 2006 that the Buildings and Grounds Division decided to make oil and sell it. Sal Genito, right, director of Buildings and Grounds, introduced this year's varieties to a crowd of 500 people at the Silo Cafe & Pub. Katie Hetrick, communications manager for Buildings and Grounds, said launch party sales totaled more than 1,200 bottles -- twice the number of last year's initial sales. There is still some left, Hetrick said, available while supplies last at the campus bookstore. This year's inaugural batch of vinegar is sold out.
