Sitting in a booth in the lobby of a Brooklyn hotel, I stared down a row of sliders, every on a separate bamboo plate. On the far left was a plant-primarily based burger from Not possible Foods. On the proper, an old-fashioned beef patty. And in the middle, the star of the show: a hamburger produced from lab-grown meat.

I am not vegan or even vegetarian. I drink complete milk in my coffee, and I cannot turn down a hot dog at a summer season cookout. But as a climate reporter, I am acutely conscious of the influence that consuming meat has on the planet. Animal agriculture accounts for practically 15% of international greenhouse gas emissions, and beef is a unique offender, with much more emissions per gram than essentially any other meat.

So I am genuinely intrigued by the guarantee that cultured meat could replicate the knowledge of consuming meat with no all that climate baggage. I had higher hopes for my taste test. Could a lab-grown hamburger be every little thing I dreamed it could be?

From left to proper: Not possible Foods Plant-Primarily based Burger, Ohio Valley Lab Burger, and Beef Patty.


“In this residence, we’re meals secure,” stated Jess Krieger, founder and CEO of the Ohio Valley meat increasing enterprise, as she pulled on a pair of black plastic gloves to lay out the 3 hamburgers I was about to attempt. My tasting would culminate in a sample of her company’s Wagyu burger.

We began with a plant-primarily based burger from Not possible Foods. Founded in 2011, the enterprise produces plant-primarily based meat options. A particular ingredient is heme protein, which is spewed out by genetically engineered microbes and sprinkled in for that meaty flavor. I took a modest bite of the Not possible burger, and if you ask me, the taste was a quite fantastic approximation of the true factor, though the texture was a bit looser and softer than beef. (If you happen to be primarily based in the US, you might have attempted this 1 your self. In Europe, heme hasn’t been authorized by regulators but, so Impossible’s items there do not incorporate it.)

Subsequent on the list was the beef burger. By the way, none of these sliders had any sauces or toppings on them, and Krieger says they had been seasoned identically, for a fair comparison. I genuinely do not have substantially to say about this – it was just a common burger. Even as I chewed, I had a glimpse of the final item on my tasting menu for the day: the lab-grown version.

The future of meat?

Ohio Valley Wagyu burgers start off as a modest muscle biopsy taken from a young cow. The cells from that sample, mainly muscle cells and fibroblasts (which can transform into fat cells as the cow grows), can then be cultured in the lab, increasing and dividing more than and more than once more. The mix of muscle cells, fibroblasts and mature fat cells in the final item is crucial to flavor, says Krieger.

When the cells have proliferated adequate, they are rinsed with salt water to clear the broth they had been grown in and stored in the refrigerator overnight. Then they can go to the hamburger the really subsequent day. Most of Ohay’s operate nevertheless requires location in a modest lab, Krieger stated, so in total it took about 3 weeks to develop all the cells for my slide, along with 4 other people the group planned to serve at an occasion later that day.

The burger on my plate was essentially only about 20% lab-grown material, Krieger explained. The company’s strategy is to mix their cells with a plant-primarily based meat base (she would not inform me substantially about this base, unless it really is Ohio’s recipe). Plants can assist supply structure for the meat option, Krieger says. A different huge benefit of this blending strategy is monetary: lab-grown elements are high-priced, so blending plants can assist retain charges down. My colleague Niall Firth wrote about this approach mixing laboratory and plant meat (and the Ohio Valley) in 2020.

The world’s very first lab-grown hamburger, served at the 2013 conference, expense an estimated $330,000 to make. The field has come a lengthy way given that then, with Singapore becoming the very first nation to enable the industrial sale of lab-grown meat in 2020. And in November 2022, a US enterprise cleared 1 of the final hurdles from the Meals and Drug Administration.

All this context swirled about in my head as I picked up a lab-grown hamburger and took a bite.

It was surely distinct from beef, but perhaps not in a poor way. To me, the lab-grown hamburger bore a sturdy resemblance to the 1 from Not possible Foods. The texture was equivalent, which tends to make sense given that it really is mainly produced from plants.

Taste-smart, I believed the lab-grown meat may be a small closer to a beef burger, but I wondered if I’d really feel the identical way if I did not know which was which. Did my brain trick me into considering it tasted much more like meat, given that I knew it had animal cells in it? I bit into all 3 burgers once more to attempt to figure it out. I am nevertheless not certain.

There are several unanswered inquiries about lab-grown meat, like no matter whether organizations will be capable to generate it on a industrial scale, how high-priced it will turn out to be, what the climate impacts will essentially appear like, and no matter whether anybody will consume this in the very first location.

General, we could likely use much more climate-friendly selections than beef nowadays. I know beans, tofu, and lentils exist, and I have some excellent vegetarian recipes that I turn to occasionally. But I am just not prepared to give up hamburgers totally. And I am not alone—the vast majority of the world’s population nevertheless eats meat.

As the stress of climate alter grows, much more and much more men and women are seeking for compromises: options that can replicate, or at least approximate, the knowledge of consuming meat. I wonder if lab-grown meat can do something to turn us away from the old-fashioned version.
