US-05 Need some very fast advice

[djonesax]

I got moving to fast I guess and I hydrated my US-05 yeast with plain tap water and forgot to boil it. I am chilling now and the rehydrated yeast has a thick layer of foam on top which I havent seen before. Any way think it will be ok to pitch it or wait and buy more tomorrow, 20 hours from now?

Thanks,

David

I just found a leak on my chiller, it was running a slight stream into my cooling wort for 5+ minutes.
I wish us both luck...

Do you live in Sweet Water, Texas. Must be the sugar in the water that proofed your yeast. (That's a joke.)

I never boil my well water for rehydrating yeast, just bring it to 90°F. I don't boil my top off water either. Never had an infection.

An infection could not present itself that fast. Your okay.

Your OG will be slightly lower than planned. Chlorinated water?

I know it wont be infected so quick, heck the foam was probably from swirling. I just worries because I always boil the water and forgot this ime. I guess I'll just pitch it and have a home brew.

 

[signpost]

A homebrew or two will definitely solve any issues that might arise.

But really, it'll be fine. I never boil my water for hydrating yeast. And I've never had an issue.

That's the spirit, bud.

It's important to keep in mind that you can clean and sanitize the hell out of everything, but you're never going to brew in a 100% sterile environment. The goal is to give the yeast the best chance to overtake any invaders.

If your cleaning regimen was good, you did a reasonable job with your sanitizer, and you pitched a healthy amount of yeast, you'll probably be just fine.

just for interest.... my rehydrated yeast always foams up good, tap water. Relax friend, crack a cooly pop

 

[Gnomebrewer]

US-05 always foams up heaps for me as well (with no sugar).

I do boil my water to hydrate yeast, but a mate I often brew with never does (he uses straight tap water).

Also, think about the number of kit beers (cans of hopped wort) that are nearly always made up with straight tap water. They taste like alcoholic toilet water, but they virtually never get infections (not unless there was another source of infection).

You'll be fine with good, clean tap water.

Chlorinated city water. It was a minuscule amount. Not a stream of water, and no real change in volume, just a little tiny stream from the hose connection.
The gravity and chlorine don't worry me much. The risk of infection from hose water is a concern, but it is what it is at this point...

 

[Owly055]

I wouldn't worry a bit...... the foam is normal. Fermentis yeasts are extremely dynamic, and take off fast in my experience. I personally don't obsess about sanitation nearly as much as I did early on. None of my fermenters has a bubbler anymore for example, and I've never had an infection in almost 100 batches. (today was brew 95) All are Walmart ice tea dispensers, and all get a rubber band which is 2" wide and 15" long around them... and manage to breath. I've had leaks of tap water into the wort from the chiller, found a dead fly in one brew, and various other things, and never had a problem. I plan to brew a batch with guppies in it next ;-) Note that I have extremely high quality well water.............

Thanks for the replies. It was just weird because I have used us-05 a few times and it has never poofed up like that when re-hydrating. Figured it was likely normal but then remembered I didn't sterilize the water. I'm not going to sweat it, thanks.

Worry about an infection from chlorinated water? UHH, isn't the function of chlorine to dis-infect? Shouldn't the worry be about the chlorine killing the yeast or adding unwanted flavors?

I have used a charcoal filter for city water for the last 10 years, but we have that other chlorine here so it doesn't do much. Never bought other water.

Why the huge worries about infection? I have thrown away less than 10 batches in 20 years, that includes many batches brewed in a dirt floored basement, with a sump pump. I was brewing 20-30 batches a year then.

RDWHAHB! It is beer!

 

[Subdivisions]

The chlorine is your friend since it will kill micro-organisms. Many people top off their extract batches with multiple gallons of unboiled tap water and don't have a problem. Chlorination can be a problem since it can cause a band-aid taste but for the amount you're using I wouldn't worry about it.

 

[chisena]

Pitch it. Infection is so unlikely...

 

[kh54s10]

In most cases rehydrating dry yeast will create some foam. I would worry more if there was no foam.
I never boil my rehydrating water. No infections thus far. I usually use a Brita filter though.

There should be no issues for either of you.

 

[andysim]

All is good. I never boil my hydration water

 

[kombat]

Like the others, I also never boil my rehydration water. I take it straight from the tap, mixing hot/cold water until I get it to 85° F, then pour out the excess until it's down to 115 mL. Never had a problem.
