Dubbed Frankenburger, the engineered meat was eaten in London at a news conference.
The patty was made from the stem cells of cattle and consists of thousands of strips of both lean muscle and fat grown in a lab.
The BBC was there for the tastings at a London restaurant and report that most who tried a bite were impressed with the offering.
Josh Schonwald writes the “Taste of Tomorrow “ in Chicago. He said "the mouth feel is like meat. I miss the fat, there's leanness to it, but the general bite feels like a hamburger. What was consistently different was flavor."
The burger had a little help with texture and flavor.
It was dyed with beetroot juice, and breadcrumbs, caramel, and saffron were all added for flavor.
One of the biggest drawbacks to the new technology is the cost.
Google co-founder Sergey Brin funded the $330,000 it cost to produce the burger.
