I can't imagine the world without yeast... I love bread

[TheVanillaFaceXD]

But where do baby yeasties come from in the wild?

[youremiasgotthelf]

Best Video so far regarding this topic, thanks!

[juanchavez]

this gave me more questions than answers!!!!

[raystravel]

But what is yeast? You say some yeast cells are added to the liquid. But that doesn't explain what yeast is and where it comes from

[tyson]

But where did it all start from??


Where did the sort of "Master yeast" start?

[realCliffordJones]

But how is the original yeast derived before you make more of it?

[tomastomas]

As a baker who loves beer, i thank you.

[riskirills]

i don't want to know how yeast is made with this modern technology,
i wanted to know how yeast is made in 1000 B.C.

[realrunningdog_]

So I have a question, I made I sort of “ putty” with flour water and oil, is it possible it got yeast? It’s ful of air bubbles.

[the_th_kozmos]

Does anyone know what the culture medium contains? And what are the added minerals?

[comment-section-memes]

What type of nutrient broth is used for the large containers?

[nikhilmore]

Okay so everyone, As everyone is asking hence im answering it, the first yeast or the pure culture, is culture of yeast that is isolated to 99.99 % purity...such first culture is obtained after successive isolations of yeast strains in multiple steps which can be isolated from Air, Soil or water commonly found in nature.

[connorcookbird]

how do the strain banks get the yeast cells. I came here and got every answer I wanted accept for how the yeast was got. the video starts with, getting yeast from the yeast bank

[meetoo]

What are the raw materials used to make yeast

[futureteacher]

If oxygen is provided then it should use aerobic respiration and not fermentation
Please clear my confusion

[elizabethbennet]

i got here from adhd and people are panic buying yeast and flour rn so i was wondering how to make it myself..since the coronavirus apocalypose is apparently coming

[iannalemme]

i still don't understand... you are making yeast out of yeast, but how was the original yeast created?

[shoddyproductions]

I'm doing this with my last pack of dried bread yeast (pandemic style). Is sugar and water enough to feed it ? Are there any tricks to ensure it's only yeast growing ? Can I feed it like a ginger bug, or just give it a giant pool to swim in ? I see in addition to water, air, and molasses, you add nutrients... What sort of treats are you giving the yeast to make it so happy ? Any help is appreciated !

[TaigiTWeseDiplomat--Formosan]

So yeast can live without water just like the instant yeast I bought.
