How much of an impact do yeasts strains have on their [beer] products? Is this a significant game changer?

I want to craft delicious fermented foods. Beer, bread and pizza are a few of my motives.

I have various (German) beers I absolutely love that I would like to propagate a culture of yeast from to make these foods and beverages. With the impression that these tasty beer's yeast cultures could be a factor that would reflect in the tastiness of these products.

My concerns are how much of a difference propagating such yeast strains are VS. other factors of the product's various ingredients. Mainly, Will I notice a big difference in the individual yeast cultures alone, aside from the other ingredient factors? Or does it not matter as much as the other ingredients?

Yeast can change everything in a beer.

The french brewery le père l'amer released 2 beers (or 4) on which they brewed one batch of beer, splitted it in 2 and put one yeast on the first part and an other yeast on the second.

This made 2 beers who looked, smelled and tasted completely differently (and they did not have the same percentage of alcohol too).

Here they are on untappd :

yeast battle #1 verdant VS yeast battle #1 WLP644

yeast battle #2 dry english VS yeast battle #2 london fog

  • Good answer but did you mean to highlight "le père l'amer" or provide a link. A link would be more useful.

    @Eric s this was just an example I know that proved that just changing the yeast cam change everything. I put untappd links so you van see via the photos and the comments how different the beer are with just the yeast being changed.
