Guinness is trialling a new Black Lager in Northern Ireland.
The lager, which is being tested in the on and off-trade, is cold filtered and uses Guinness roasted barley to give it a distinctive black colour.
It is fermented using a special Guinness lager yeast.
Michael McCann, head of Diageo Northern Ireland said: "I am delighted that Northern Ireland consumers will be able to experience Guinness Black Lager. Like all lagers, it is characterised by its refreshing taste. The addition of Guinness expertise, roasted barley and a late hopping imparts a taste that is unique among lagers."
McCann added that the launch of the 330ml bottles will be supported by a heavyweight advertising campaign as well as in-bar promotions.
It has not yet been confirmed how long the trial will last before a decision is made as to whether to make the lager available in the rest of the UK.
