The seventh annual event, celebrating brewers and cuisine and with a line-up of entertainers and activities for children, will be held in Forsyth Barr Stadium, on Friday and Saturday, November 8 and 9.
OUSA events and venues operations manager Jason Schroeder said in 2018 there were more than 90 food and beverage stalls.
"This year we obviously are focused on quality across craft beer and food offerings and ensuring we cater for public demand, as well as raising the event bar," he said.
"The decision to extend the festival to two days was made to ensure that as many people as possible got to experience the event."
Friday would be R18 from 3pm to 9pm, while on Saturday families would be welcome.
Mr Schroeder would not divulge any details of the entertainment, but said it would be "in line with the demographic and sure to please".
Last year's event featured headline acts Bic Runga, and Elemeno P. Tickets to last year's event sold out in a matter of minutes and 6200 ticket-holders attended.
A cheque for $9000 raised from last year's event was presented to Youthline Otago.
Tickets for this year's event will go on sale in July.
