    Could labs replace your natural chocolate?

    Listened

    In progress

    Chocolate may fill grocery store shelves around the world, but the raw product that powers chocolate is far more selective. The majority of chocolate farms are found in West Africa and South America – just 20 degrees north or south of the equator. Each farm produces chocolate of a different flavor. Some cocoa tastes fruitier; others, more floral. Nutty. Earthy. Spicy. But what drives these different flavor profiles? And can it be recreated in a lab?

    Chocolate may fill grocery store shelves around the world, but the raw product that powers chocolate is far more selective. The majority of chocolate farms are found in West Africa and South America – just 20 degrees north or south of the equator. Each farm produces chocolate of a different flavor. Some cocoa tastes fruitier; others, more floral. Nutty. Earthy. Spicy. But what drives these different flavor profiles? And can it be recreated in a lab? A team led by scientists at the University of Nottingham in the UK sought to find out and published their results in the journal Nature Microbiology this week.
