Finnish scientists create 'sustainable' lab-grown coffee

"It's really , because there is nothing else than coffee material in the product," Heiko Rischer tells AFP, pointing to a dish of light brown powder.

His team of researchers at the Finnish technical research institute VTT believe their coffee would avoid many of the environmental pitfalls associated with the mass production of one of the world's favourite drinks.

The coffee is not ground from beans, but instead grown from a cluster of coffee plant cells under closely controlled temperature, light and oxygen conditions in a bioreactor.

Once roasted, the powder can be brewed in exactly the same way as conventional coffee.

Rischer's team used the same principles of cellular agriculture that are used to produce lab-grown meat, which does not involve the slaughter of livestock and which last year was given approval by Singapore authorities to go on sale for the first time.

"Coffee is of course a problematic product," Rischer said, in part because rising are making existing plantations less productive, driving farmers to clear ever larger areas of rainforest for new crops.

"It's really coffee, because there is nothing else than coffee material in the product," Heiko Rischer tells AFP, pointing to a dish of light brown powder.

For the time being, they are only allowed "to taste and spit, but not swallow it," said research scientist Heikki Aisala.

Rischer estimates it will be a minimum of four years before the team's lab-grown coffee gains the regulatory approval and commercial backing to enable it to sit alongside its conventional cousin on the shelves.
