Summary:

Researchers built a hamburger from strips of muscle grown from cow stem cells. It was tasted for the first time in London this morning.

Three taste testers bit into the first hamburger made from lab-grown beef Monday morning in London. They labeled it similar in texture and lacking in flavor compared to the real thing, but the bigger surprise came when the team behind the burger revealed their financial backer: Google co-founder Sergey Brin.

Brin’s $325,000 went toward a team of researchers called Cultured Beef, which grew stem cells from cow shoulder muscle into strips of muscle fiber. Around 20,000 strips were mixed with bread crumbs and a binder, plus red beet juice and saffron for coloring, to form the burger tasted Monday — an event Brin said many people would consider science fiction.

“I actually think that’s a good thing. If what you’re doing is not seen by some people as science fiction, it’s probably not transformative enough,” Brin said in a video describing the project. “If it succeeds there, it can be really transformative for the world.”

At the tasting event, which was streamed live online, Maastricht University professor Mark Post revealed his team’s burger patty in a petri dish. Cornwall, U.K., chef Richard McGeown then fried it in a pan with a substantial amount of butter. He said it cooked in about the same time as a regular beef burger.

Nutritional researcher Hanni Rützler was the first to bite into the burger.

“It’s close to meat,” she said. “It’s not that juicy, but the consistency is perfect. It’s not falling apart; it’s really something to bite into.”

The burger had no fat in it, as Cultured Beef has yet to develop a way to grow meat that replicates beef’s natural fat content. Even frying the patty in a substantial amount of butter wasn’t enough to hide that the burger needed fat. The tasters also wished the burger, which was served plain without condiments or other toppings, had salt, pepper and other spices in it.

“The texture, the mouth feel, has a feel like meat,” food writer Josh Schonwald said. “The absence, I feel like, is the fat. It’s a leanness to it.”

Post said he was overall happy with the tasting, which was meant to prove that they could grow meat in a lab.

“It’s a very good start,” Post said. “Tt will take another couple of months before we have [the fat] down. That’s clearly the next step.”

Cultured Beef has pushed hard on the environmental angle for eating lab grown meat. Brin also said he funded the project for its potential to create a sustainable source of meat.

“Quite frankly, vegetarians should remain vegetarians. That’s even better for the environment and for the animals than a cultured beef alternative,” Post said. “We’re basically catering toward letting beef eaters in beef in an environmentally friendly and ethical way.”
