Prince Charles and Camilla, Duchess of Cornwall continued their annual three-day visit to Devon and Cornwall on Wednesday. While joining author Sir Michael Morpurgo at a lunch club for local residents in Iddesleigh, England, Queen Elizabeth's eldest son enjoyed a pint of beer, cheerfully raising the glass before taking a sip. While drinking on the job is usually frowned upon, the royals are known to occasionally sample local drinks while on tour. For example, last year during their visit to Ireland, Kate Middleton and Prince William memorably sipped beers at the Guinness Storehouse to toast the Irish Guards. Royal Bottoms Up!

Earlier this year, Queen Elizabeth, 95, approved the sale of a range of beer brewed from plants grown on her Sandringham estate in Norfolk. Sold at the Sandringham gift shop at $5.50 for a 500-milliliter bottle, the beers come in two varieties: a cold-filtered, traditional English "bitter" and a stronger Golden IPA described by the gift shop as "uniquely natural."
