Star San and yeast

[Westermans]

May be a dumb question but will star San kill yeast if diluted properly? I spray everything. When I washed my yeast I sprayed a good amount on top of my jar before sealing. It went into the yeast mixture before I closed it up. Am I ok?

Yep. You are okay. Starsan breaks down into things that yeast like. As long as good amount != 1+ oz then I wouldn't worry.

I liberally use a spray bottle and starsan on pretty much everything. I'll spray the outside of my starter and the aluminum foil that I place on top. I've brewed 40-50 batches and have never had any issues.

Don't worry. I think it's even been stated that it is a yeast nutrient

 

[Westermans]

Great thanks for the reassurance.

Great question. If my brewing area is rife with wild yeast, and I use Star San to sanitize, then the wild yeast will thrive and "infect" my beer. Good to know.

HA! It is not a yeast nutrient in its "sanitizer" form. It breaks down to a yeast nutrient. If you coat your brewing area with starsan you should be pretty safe. Best bet is to take a quick bath in it prior to working with yeast. I also recommend a face mask to keep you from breathing into the wort at any time!

The "Take Some Advice" guy shows how it's done. Work in a well lit underground bunker where you can see the little buggers flying around. Hold your breath while working.

Haha that was an awesome episode

I too have hearts star an breaks down into a yeast nutrient and one shouldn't fear the foam, but does anyone know what exactly it breaks down into?

Here are too hearts for you ♥♥!!

But I don't think that's what you heard.

From another thread on this site:

It's all about the concentration. At the prescribed dose, it destroys bacteria cell walls. At dilute concentrations, it mostly dissociates, freeing phosphate for yeast to use. Yeast nutrient that you buy in the store is primarily nitrogen compounds and phosphates- the breakdown products of StarSan are phosphate.

Thanks

Read the label; it's phosphoric acid with a surfactant included. You will get a pH=2 solution, which if not diluted will kill yeast. Once diluted and becomes part of the ferment it will probably act as a nutrient, phosphate. Don't get it your eyes!
