Bethesda owner ZeniMax recently filed a trademark application for "Nuka Dark," which is the in-game drink introduced to the Fallout universe in Fallout 4's Nuka-World expansion. The trademark, filed on August 15 with the United States Patent & Trademark Office, covers all manner of boozy items. The Goods & Services line of the application covers, "liquor; bourbon; spirits; wine; beer, ale, lager, stout; beverages containing alcohol; whisky, vodka, gin, rum; liqueurs; aperitifs; digestives."

As the Fallout Wikia explains, Nuka-Cola Dark is an alcoholic version of Nuka-Cola. It is really strong, carrying a 35 percent (!!!!) ABV in the game.

In 2015, Bethesda partnered with beer giant Carlsberg for Fallout 4-inspired beer that was simply called "Fallout Beer." The new trademark filing suggests Bethesda is making a real version of Nuka-Cola Dark, and my oh my it would be strong if really has a 35 percent alcohol by volume.

Beer company Sam Adams recently launched a new beer called Sam '76, and it would be a real shame if Bethesda doesn't partner with the company for a Fallout 76 beer.
