Rehydrated Yeast Question

[andy6026]

My wort chiller failed, putting hose water into my brew. I realized the malfunction in time such that I only added about 20% extra water. I'll probably boil a bit of extract to get my numbers where I want them. While this obviously isn't ideal, the brew is salvageable.

However, my question pertains to the rehydrated yeast I prepared while the brew day was underway. The kettle is currently cooling via the 'no-chill' method, and I bunged the rehydrated yeast into the fridge about 3 hours after rehydrating it. The wort should be cool enough for me to pitch the yeast tonight (about 8 hours after rehydrating).

Should I use this already rehydrated yeast or should I get fresh yeast tomorrow? Thanks!

dry yeast pack they cost what....2 dollars. I would pitch a new pack better safe than sorry compared to a 40-50 dollar brew.

I'm in Canada and this one cost me $8. I'll also need to take a second trip to the brew supply store.

I would add a little wort to the yeast, wait 30 mins and then pitch into the full batch. Unless you are afraid that you did something to contaminate the yeast, the worst that could happen in 8 hours is that the yeast have used a portion of their glycogen stores and need a little nutrient before being put to their task.

Take a pint of your wort ina sanitized vessel and put in thefreezer to chill it to ~70F

Pitch your rehydrated yeast into this

Tomorrow when the batch is cooled. pitch the makeshift starter into the brew.

All will be well.

If you trust your sanitation, your jar/measuring jug of rehydrated yeast was covered with sanitized plastic wrap, and you know nothing has dropped into since, it should be as good as mixing it up fresh, don't you think?

Just take it out of the fridge a few hours before pitching so it can get to your wort's pitching temp. Spray the outside of the jug with Starsan right before pitching. You know the drill...

Astonishingly, a sachet of Safale runs $4-4.50 here, not $2.

+1 to adding some wort to the yeast slurry before pitching.
And don't forget to aerate!

Here's what I would do, safely house the yeast in a small starter for the night, pitch in the morning.

Thanks for the advice, everyone! I boiled up a pound of extract with some spare hops, transferred the original brew to the fermenter and pitched the yeast I already had. The recommendation to house the yeast in a starter was the best idea and I would have done that had the wort not been cool enough when I got home.
