Duchess Catherine admits she's never been able to master the art of pulling a pint.

Prince William and Duchess Catherine

The 34-year-old royal and her husband, the Duke of Cambridge, visited Healey's Cornish Cider Farm on Thursday (01.09.18) and the brunette beauty quipped that she's a terrible barmaid whilst pouring a brew for William.

She joked: "I've never mastered this!"

However, after tasting the boozy concoction, William assured Catherine, also 34, that it was just as good as the stuff served at a pub and it tasted "just like it does in the pub."

And the royal couple's boozy visit didn't stop there, they then downed 120-proof whisky.

The owner of the establishment, Joe Healey, showed William and Catherine bottles of cider that had matured into different spirits including brandy and rum and whisky.

A panicked William said: "Rum?! This is where the engagement really goes downhill!"

However, Catherine seemed to enjoy it and said it was "delicious".

Lightweight William said if he'd end up falling over if he drank the whole glass.

He added: "I'll fall over if I drink that!"

The cider farm was just one stop on the couple's two-day visit to Cornwall and the Scilly Isles.
