Admiral's Old Antisocial

 was a beer sold by the Witch and Whirlwind bar on Dellah. Benny Summerfield loved this beer. (PROSE: Dry Pilgrimage)

Arielle tried to order some Antisocial from the Il-Erik when she got a little lost in the Pierhaven section of Yendip, capitol of the planet Yquatine on Treaty Day. Unfortunately, the Izrekt bartender was out of it. It disappointed Arielle, since the budding xenobiologist had wanted to try the favourite beer of one of her heroines. (PROSE: The Fall of Yquatine)

Behind the scenes
Benny's name is not directly mentioned in The Fall of Yquatine, but the heavy implication is that Arielle's heroine was Benny.
