Professor Mark Post of Maastricht University, otherwise known as the ‘Hamburger Professor’, presented the first cultured beef burger back in 2013, it cost over €200,000. In 2019, he claimed it now costs about €9 per burger. Whilst this is still much more expensive than any hamburger you would find in a supermarket, it shows the massive progress that has taken place and the potential for the future.
