The FUNKIN brand gave people a chortle this April Fool’s Day.

Consumers were invited to visit the FUNKIN Fruit Farm, the only farm to grow the rare blue raspberry, at a two-hectare farm in the English countryside.

The blue raspberry is the only fruit in the world belonging to the GLUM (Growth Labour Under Melancholia) vegetation family, meaning they have a different growth cycle to traditional raspberries, and are instead known to thrive in colder, darker environments.

While their unique blue hue can come and go in a seasonal pattern, it’s typically more apparent during the gloomier winter months.

The farmers at the fruit farm have been known to adopt alternative methods to ensure that each blue raspberry, which is grown as the key ingredient in FUNKIN Cocktails’ Blue Raspberry Martini, receives the individual love and care it requires to reach the optimum level of winter blues for a guaranteed bountiful crop.

According to the growers, these methods include Sally Rooney readings and serenading their seeds with pop music playlists, including Olivia Rodrigo and Lana Del Rey.

A day's picking will then finish off with a complimentary tasting of FUNKIN cocktail’s new Blue Raspberry Martini.
