The new Netflix series House of Guinness officially premiered on the streaming platform on September 25, 2025.
The period drama is “inspired by true stories” and includes real-life historic figures, like Sir Benjamin Guinness’ four children.
However, series creator Steven Knight admits that he took creative license in the project and “fill[ed] in the gaps” himself while writing the script.
If you love a scandalous historical drama and/or splitting the G, boy, do I have a show for you. The creator of Peaky Blinders, Steven Knight, is reuniting with Netflix for another gritty period saga packed with sibling rivalry, secrets, and perfectly poured pints.
ICYMI, the streaming platform dropped all eight episodes of House of Guinness on Thursday—and yes, if you haven’t picked up on my hints already, it is indeed about that Guinness family. The series follows the aftermath of patriarch Sir Benjamin Lee Guinness’ death, his four children, and the feud that erupts between them after the reading of his will. And while I’m sat for the show nonetheless (and canceling all weekend plans to binge every single episode), the premiere begs the question: How true is the story?
Is ‘House Of Guinness’ A True Story?
The series opens with a quick disclaimer that the plot is “inspired by true stories,” but what exactly does that mean? Well, the characters in the show—specifically, Guinness’ four adult children—are all real historical figures and part of the family dynasty. Some “remarkable” (and very real!) events from the family’s history also play out on the show, but according to Knight himself, there was definitely a bit of creative license to come up with the rest of the script.
“There’s no Facebook, no Instagram pages,” he told Netflix’s Tudum of his research for the project. “What I had to do is take things that these family members did, things that they said, achievements they made, mistakes that they made, and use them as stepping stones. Then I had to fill in the gaps myself.”
So the answer is…sorta! While the premise, characters, and some of the key events are very much real, not everything from the series is 100% true. However, that’s pretty much the case with every historical drama.
“[The scripts] are rich, full of brilliant characters—a piece of history. Tonally, it’s playful, funny, smoky, hot, and at the heart of it is a great story with a great family dynamic,” series star James Norton said. “The show has everything—rich characters, brilliant relationships, and a hot, textured world to learn about.”
Which ‘House Of Guinness’ Plot Lines Are Real?
While there is plenty to unpack, let’s start with a few of the key storylines that were very much part of the family’s history. For starters, Sir Benjamin Lee Guinness was indeed the grandson of brewery founder Arthur Guinness. He took over in 1839 and left it to his sons, Arthur and Edward, in his will, People Magazine reports. Yet the dynasty would later be shadowed by scandal, with heirs dying young or falling into addiction—tragedies that fueled whispers of a “Guinness curse.”
Arthur was also involved in the political scene in Ireland. He was elected Conservative MP for Dublin in 1868. His election was voided due to his election agent’s bribery, though Arthur himself was not personally found guilty of the unlawful efforts. And while he did receive a death threat in 1872, it wasn’t actually related to his second Parliament run. Decades later, the family’s name would resurface in darker headlines, from the assassination of Walter Guinness in 1944 to the Guinness share-trading scandal of the 1980s.
Which Plot Lines Are Fake?
Like Knight pointed out, there are plenty of exaggerated (and straight-up fictional) moments in the series. But…what were the fictional plot lines? In the series, Benjamin forces Arthur and Edward to take on brewery leadership or lose their inheritance altogether. However, that wasn’t the case. In reality, they could have bought each other out for £30,000 plus half the stock value.
Edward is also shown in the series as the mastermind behind Guinness moving into the American market in the 1870s, but the beer was first shipped to America long before Edward took over, the outlet reports.
And while much of the cast is based on real people, there were a few fictional adds, like Edward’s illegitimate cousin and business partner, Byron Hedges, as well as Irish Republican Brotherhood leaders Patrick and Ellen Cochrane. Though it is important to note that the revolutionary group was very much real in Ireland at the time.
