But how much do you really know about this famous brand?
Before he went onto become famous in Game of Thrones, the Hound (aka Rory McCann) was the face of Scott's Porage Oats.
We are guessing it's the secret as to how both he (and his brother the Mountain) grew to be so big!
Setting many hearts aflutter across the UK as he reached for the top shelf box of the famous Scottish porridge, Rory brought the kilted mascot to life for a new generation.
6ft 2in Jay Scott enjoyed worldwide fame in the 1950s and 1960s as a Highland Games heavyweight champion, his prodigious talents even attracted the attention of Hollywood bombshell Jayne Mansfield.
Rumour has it, though, that he didn't know his image was being used by the porridge company.
According to son Rob, the first his dad knew about his picture being on the cereal packet was when a friend spotted it in a shop.
And, at the time, there were rumours that he didn't receive any payment from the oats company for the use of his image. "I think he only got a one-off payment when he approached them," says Rob.
If you’re wondering about the company’s unique spelling of porridge, then that’s a marketing trick: to distinguish themselves from their rivals, they combined the spellings of “porridge” and “potage” – a French word for a thick soup – and ran with it from 1914 onwards.
They even made an advertising campaign based on the fact with the slogan "spell it either way and it means a delicious hot breakfast, but there is a difference. There's something special about Porage because Scott's Porage is made from genuine Scottish oats, the real stuff".
One of Scotland's oldest men, former greyhound breeder and racer Neil McNeil, who recently celebrated his 105th birthday, believes the Porage Oats are the secret to his long life.
Insisting on a daily bowl of the traditional Scottish breakfast cereal, and often requesting a second bowl as a midnight snack, his daughter, Sheila, 72, says he is almost fanatical in his love for the brand, she said: "I have never known anyone to be such a big fan of porridge – he swears by having a bowl every morning to stay in good health and I’m sure he would have it for every meal if he could."
Two brothers, A & R Scott, began the company in 1880 when they started making Scott's Midlothian Oat Flour in the Kingston Dock area of Glasgow.
Even the brand know little of their founders though with their earliest records attributing the running of the business to partners Robert Lauder, who looked after the technical aspects, and William Allen, who controlled the finances.
Since 1984, scientists at Harvard University’s School of Public Health have been following the dietary habits of around 100,000 people and have now come to the conclusion that those of us who regularly eat whole grains, such as porridge oats, can expect to live longer and healthier lives.
Just one small bowl of porridge a day can increase life expectancy by 5 per cent, and reduce the risk of death by heart disease by 9 per cent.
Scott's Porage Oats were so successful that they forced their biggest rivals, Quaker porridge oats (who are owned by Pepsico) to buy them over in 1982.
In 1971, the company drew a lot of attention for their use of a Tartan 1934 Rolls Royce (pictured here in George Square in Glasgow) to promote the brand across Scotland.
