Genuinely fascinating. Never thought about where yeast comes from. Let alone specific strains.

[Tuxedoz]

Where it came from was the yeast of my worries, but this raised my interest.

Imagine being the first person who ate leavened bread... Almost as good as being the first person who ate cooked meat, I would imagine.

There's a brewers yeast called "Wild Brew Philly Sour", it's made by Lallemand. It produces alcohol and lactic acid for sour beers, it was found in a graveyard in Philadelphia.

"and after 48 hours you get 1 kilo, and after another 48 hours it will give you 13 AND after another 48 hours it will take over the world lol. Insane growth rate.

I'm SO confused. How did we not know this. How did our ancestors discover it. It makes no sense. 😩🤔😂

Amazing how the Egyptian can found yeast during ancient times!

All though i sped this up, haven't noticed where it explains "What is yeast?".

[alchinov]

What about yeast that just grows on its own when making fermented products without any starter culture?

[chlorone]

good thing they didnt show how to extract the microscopic fungi from the rotten trees n stuff. else people would be raiding the forests for their homemade yeast ;D

Fun fact, if you get lost when searching in the woods, just head yeast to find your way back. 😢😮😂

The professor forgot to mention the yeast in the air.
Most remiss of him.
It's abundant in people's homes, which is why it's so easy to cultivate your own for baking, creating an endless supply at a fraction of shop prices.

[justinscarritt]

Still don't explain where the vial of yeast is collecyed from originally.

[paulwright]

I remember an episode of a yeast on a piece of paper in Poland, where is that episode 🤔
