What Peter's 'special cheese' on 'Succession' reveals about his character, according to the cheesemonger who says he sold it to the show

• A cheesemonger in Jackson Heights, New York, says he sold "Succession" some cheese.
• He believes the cheese used in the series finale was an English cheese called Montgomery's cheddar.

"Don't touch that! That's Peter's cheese," Lady Caroline Collingwood exclaims in the final episode of HBO's hit series "Succession." "For god's sake! I made that mistake myself."

In what quickly became one of the show's most iconic scenes ever, the devilish Caroline reprimands her hungry children and the show's main characters — Kendall, Roman, and Shiv Roy — who are looking for a late-night bite in the kitchen of their mum's Barbados compound.

That's his "special cheese," she explains. "He gets really boring about it."

So what is so special about her husband's cheese? And what does it say about Peter?

"It's one of the more amazing cheddars out there," according to cheesemonger Steffen Kenney.

Kenney, the owner of Stand Alone Cheese in Jackson Heights, New York, told Insider he sold a big chunk of Montgomery's cheddar to a representative for the show earlier this year.

He described the clothbound cheese, made from raw cow's milk in England, as "earthy" and "nutty."

There's "a lot more going on" in this cheese than in a typical American cheddar, he said.

It's also a hard, sturdy cheese that could travel to Barbados easily, he said.

Kenney is pretty sure the cheese featured on "Succession" was from his shop, though the team behind the HBO show could not confirm to Insider where they procured it before press time.

According to Kenney, someone from nearby Astoria Studios reached out to him earlier this year looking for Isle of Mull, a Scottish cheddar that's hard to find in the US.

Peter Munion is something of a mysterious figure in "Succession." In the few appearances he makes, he comes across as a starstruck social climber who is trying to get as close as possible to the Roy family's inner circle. Caroline calls him "awful" just before marrying him in season three.

I was curious why Peter, who is played by English actor Pip Torrens, would have such an affinity for this particular cheese and what the cheddar might reveal about his character. Kenney surmised that perhaps Peter was "trying to impress Logan" with a Scottish cheddar.

Unfortunately, Stand Alone didn't have that particular rare cheese in stock, so the team "settled" for Montgomery's, which is pretty similar, Kenney said.

The cheese isn't cheap at $32.99 per pound.

Kenney would recommend pairing it with a beer or a cider — definitely not the frozen loaf ends that the Roy children are served by their mother.

"That cheese doesn't belong on a knobby," he said. "That cheese belongs on a proper biscuit."
