I really need to mark the jug better. Thought it was distilled water, doh.! I am guessing this will not turn out well. Tommorrow I was planning to dry hop a different ale, gues I wil dry hop it in a secondary and learn to wash yeast. Or could I just dump the new ale on the old cake?

I've often heard it said that diluted starsan breaks down to be yeast food, however, I've never heard of folks using it to rehydrate. Hopefully, someone with more knowledge can chime in.

Don't know if they will die. What happened after you let them hydrate? Did it foam up like normal? I have used starsan in my mash to lower the ph but I guess thats not quite the same ratio.

I did this once. It turned out perfectly fine. My thinking was " don't want contaminated water. Why not use star Stan? It's a sanitizer and becomes yeast food!". Pitched it and was up and running in less than 5-6 hours. A month later I was listening to brew strong and JZ was talking about how pitching directly into the beer kills half the yeast because of the ph of the wort. star sans ph is definitely more acidic than the beer.

I dunno if that's necessarily true but I'm sure it isn't the best thing for the yeast.
I used about a cup of star San when I did that.
TLDR: you'll be fine.

I thought you shouldn't use distilled water to rehydrate yeast?

I've even nuked 1.5C of tap water for 5 minutes,then stuck it in the freezer till it comes down to a comfortable temp. Then pitched on that. But never used starsan in it. Not sure about that one,since I don't know how fast it breaks down into yeast nutrient.

I just want to be clear, it was not intentional. I thought I had used a jug of pure distilled water, but after dehydrating and pitching, I noticed it was a jug of distilled I had added starsan to. I had not marked as such clear enough it would seem.

I was hoping someone would chime in. This just 'kinda' rings a bell. I think water that is too pure is wrong because of the osmotic pressure or some such.
