Fans of the traditional English brew will soon be able to make their cuppas even more British by adding a royal splash. Milk from the Queen's dairy herd, which grazes in the fields around Windsor Castle, is about to hit the supermarket.
Dairy produce from the estate has already become a big seller at the Queen's farm shop in Windsor. And Royal Farms manager Mark Gibbs is confident it will prove just as popular around the country.
"We are starting with 70 stores and, if it takes off, we'll expand to more Sainsbury's," he reveals. "It's not our policy to deal exclusively with one retailer so we will be open for negotiation with others."
The aristocratic version will, of course, be a little more pricey than other brands. A litre will set you back 89p, making it about 20p more expensive than normal milk. But Mark says it's a small price to pay to give breakfast time a royal flavour.
