There goes another wild pregnancy rumor.
Princess Kate tasted gin and whisky in Scotland Thursday during the royal couple’s first visit to the region that gives them their Scottish titles – the Earl and Countess of Strathearn.
Touring a village fair with Prince William, Kate sampled oatcakes and ice cream and admired flowers. And at a booth run by a local distillery, she was tempted by some heather and rose-flavored gin mixed with tonic.
“I shouldn’t really try the gin because of the whiskey I had at Glenturret,” she told David Lang, one of the founders of Strathearn distillery.
“She said it was absolutely delicious,” Lang tells PEOPLE.
The drink came from a $92 limited-edition bottle produced by the one-and-half-year-old company.
Earlier, the pair had toured the Glenturret distillery, known for its Famous Grouse whiskey, where Prince William, 31, was challenged to have a “wee dram” of 68.9 proof alcohol, straight from the still.
“I’ll give anything a go, [but] I will probably regret it later!” William said.
“I’m definitely going for that one,” he said, while Kate, 32, added, “You do like a peaty whiskey, don’t you?”
Kate looked on as William took the first taste of The Black Grouse Alpha.
The Duchess of Cambridge was persuaded to try a couple of sips of whiskey she called the “girlie one” – two blends called The Snow Grouse and The Naked Grouse, both around 80 proof.
“Nice, I like them,” she declared.
Then William was handed a shot of 68.9 proof clear alcohol, and he couldn’t resist the challenge. Shaking his head, he winced and said, “That’s pretty busy,” before offering it to his wife.
“I’ll stick with that girlie one,” she said.
