She is estimated to be worth around £370m - so it comes as little surprise that the Queen's favourite bottle of red wine is a tad pricey.
The wine costs a cool £970 a bottle, according to Wine Searcher.
But, while the monarch has some expensive tastes, she is famously frugal.
In Buckingham Palace, which has 775 rooms, she has been known to switch off unnecessary lights, according to the Financial Times.
In 2011, in a drive to cut household costs, she posted signs around the palace that read: "The attention is drawn of all members of staff to the need to switch off unwanted lights. By Order of The Master of The Household."
The Queen was revealed by a documentary in 2013 to use a £20 electric convection heater in her private sitting room at Balmoral Castle in Scotland.
According to the Daily Express, palace insiders have opened up about other ways she cuts budgets where she can.
Old newspapers are used for horse bedding, string from parcels is re-used and sheets and dusters are darned.
There are also water displacement devices placed in toilet cisterns to reduce the water used for each flush.
The Queen is also thrifty when it comes to her wardrobe.
She has used the same £7.99 nail varnish for decades, according to the Evening Standard, and regularly re-wears her trademark colourful coats and hats.
Earlier this week, it was revealed that the Malta home she shared with Prince Philip is now on the market for £5m.
