The beer - a chocolate stout which incorporates cacao nibs supplied by Whittaker's - is being developed as the ''festival brew'' for the Dunedin Craft Beer and Food Festival in September.
Otago University Student's Association and festival communications co-ordinator Alasdair Johnston said it wanted a top-quality festival brew for its inaugural year and Emerson's was the natural choice to make it.
''Next year the official festival brew will actually be the [festival's] home brew competition champion's brew,'' he said.
The beer being developed by Emerson's represented an ''adult version'' of the recent L&P and Whittaker's collaboration. It would most likely be available only at the festival.
Emerson's spokeswoman Jane Hyde said the beer would be a ''fantastic blend'' of two ''quality New Zealand products''.
The brewery was keen to contribute to the festival, an event which Dunedin had been lacking, Ms Hyde said.
''Beer festivals are a hugely popular phenomenon now ... and it's pretty exciting that Otago is going to have one of its own.''
