The beer, which will be made at Brewdog's Aberdeenshire brewery, is part of a collaboration between the craft producers that will also see the Scottish firm host a series of meet the brewer events with Oskar at its bars around the country.
The tour will call in at Brewdog's bar on Aberdeen's Gallowgate on Monday, before moving on to Newcastle on Wednesday, Leeds on Thursday and Shoreditch, London on Friday.
The events will see Brewdog introduce its followers to key figures from its US counterpart, including chief brewer Dave Chichura, Stephen Houck and Chad Melis, and give them the chance to ask questions about Oskar and other craft beer matters.
Guests will also have the opportunity to sample its beers.
Oskar is said to have had a big impact on the burgeoning craft beer scene in the US since its inception in 1999, and recently saw its Dark Pale Ale named the best in the pale ale category by the New York Times.
The Oskar tie-up comes after Brewdog announced in July that it expects to close its £4 million crowdfunding drive early due to the strong take up of investors.
