13494 Treiso           Discovered 1985 Sept. 14 by E. Bowell at the Anderson Mesa Station of the Lowell Observatory.
Treiso is a village near Alba, Piemonte. Each year, a day is set aside to celebrate both astronomy and the locally produced red wine, Barbaresco. The event is called "Tasting the Universe". The name was suggested by V. Zappalà and A. W. Harris.
