Nottingham yeast - hydrate or not ?

[ChessRockwell]

That's not exactly true.

People over and over again, based on their own experiences (including side by side tests) saying that they could tell no difference either way isn't evidence to the contrary?

 

[g-star]

What I find most interesting is that YOU'RE doing exactly this.

No I'm not. Let me help you understand:

If I don't fall off the earth because I believe in gravity, its not because I'm biased towards gravity, its due to the irrefutable fact that gravity exists.

If I continue detrimental behavior despite overwhelming evidence to the contrary, it is due to a personal bias towards that behavior for whatever reason, take your pick.

Get it?

Like we've said before, it may be evidence that pitch rate isn't as significant a variable as some people think it is, but it says nothing about a potential drop in cell count due to pitching dry.

Beer tasting will always be subjecting (and non-scientific), and we can (and do) debate that all day. Whether or not rehydrating affects the flavor of your beer is something we can debate. Whether or not rehydrating affects active cell count isn't something we can debate.

As the OP let me share this with you. When I detect the first symptoms of a cold, I take 10 grams of vitamin C per day. Some folks say that amount will kill you but when I last checked I was alive. My colds tend to last about 4 days but a few years ago one lasted 10 days. I am convinced high dose vitamin C is good, but the only way of proving it is to have an identical clone of myself doing exactly the same as me.. (no rude interjections please...) and this is impossible to arrange. The best evidence I have found is a double blind cross over trial in a private school with 800 pupils. This lasted 2 terms ie 20 weeks. Pupils listed how they felt on a tick sheet. The kids on vit c in term 1 were healthier, and were unhealthier in term 2. So in each half of the trial, the placebo takers were the unhealthiest.

Well said. The actual question here is to what degree the science affects the taste, not if the science is in question. Personally I go out of my way to do everything possible to make my brews the best they can be. After all, I am the one drinking them. That being said I could probably spend less time and cut some things out of my process and make a beer that I couldn't tell didn't have the 105% effort in them. I just don't see the reason to chance it. Plus I enjoy brewing so all of the little stuff is fun to me.

 

[BOBTHEukBREWER]

As a business improvement guru in a former life, I preached you should strive for the very best quality, providing the cost was justified. This is our hobby, the time is free to most of us, so go for the best, AND REHYDRATE THE NOTTY THEN ADD SOME BREWING SUGAR TO THE JUG AND WHEN A 2 INCH MERINGUE HEAD FORMS, PITCH IT ON THE WORT....

Amen to that

hello.
never rehydrate when making wine. And I made wine a lot longer than I've made beer.

I'll restate that: I've yet to meet a commercial winemaker in Napa or Sonoma counties that don't rehydrate. And they all use Go-Ferm or a similar nutrient...it's what the guys who make the yeast say to do. I've had 3 different consultations with Shea Comfort (http://www.yeastwhisperer.com/Background.html) and he has worked the science with Lallemand. It may not be what everybody does, but it is what's best for the yeast.

 

[sj_engr]

So for the first time I noticed a lag regarding airlock bubbling. I believe it was related to sprinkling the dry yeast over the wort that still had starsan foam on some of the surface. Poor yeastie bastards never saw it coming.

Guess that's perhaps one reason to rehydrate....

 

[BOBTHEukBREWER]

I always wash off the starsan or similar with boiling water - call me old fashioned.....

 

[zachattack]

I won't call you old-fashioned, I will call you wasteful, inefficient and paranoid. Starsan doesn't need to be rinsed, doing so makes it pointless to even use the product. Since it's just a weak acid, there's nothing bad that happens if a bit (or more than a bit) of Starsan gets mixed with your beer. It dilutes out to phosphate which the yeast will happily eat...

If you don't "believe" the basic science behind that, then I don't know what to say.

For a "weak Acid" sure can shine the crap out of copper in a dilluted state..........

 

[zachattack]

I was referring to the diluted state, my bad. I've made the point in other posts that Coke will do the same thing, in fact it's a stronger acid than properly diluted Starsan. Household vinegar is also stronger than Starsan.

To be clear, phosphoric acid is a weak acid. At least from an inorganic chemistry standpoint.

What the hell. I'll start it for the OPer again: "Nottingham yeast - hydrate or not ?"

Hydrate with Star San

I hear the secret to great brews is rehydrating in a bit of cloudy urine. Still trying to get mine cloudy.

 

[BOBTHEukBREWER]

you can clean a dirty copper coin with HP sauce...

 

[grimzella]

Right! We're not going to let our yeast debate be settled by silly things like "science"!

Remember "Science" now accepts the big bang theory. 20 years ago, they would have laughed in your face. science changes all the time

That's right. If you want absolute and final answers you'd better turn to the only place you can get them. But God isn't talking about reydrating Notty, to my knowledge. So it's tea leaves or science. I'm sticking with science.

During the cold war the Soviets thought that as long as they had the numbers they could not be defeated. So they built a gigantic army and huge stockpiles of crap that was unreliable, at best.
Fortunately we will never know if 50,000 cheap thin armored tanks can defeat 10,000 well built durable tanks. (point 1}
Point 2: People that quote only a small part of your post in order to make their point are better suited to write campaign adds than comment on beer brewing.

Unicellular reproduction is a bit easier to study and experiment with than purely theoretical universal origin astrophysics. So I would say this is a poor analogy, to put it mildly.

This is a basic, well established concept that isn't up for debate. It's mind boggling how difficult it is for some people to accept it.

your too easy. don't you know.. this is why we have over 12 pages of argument. its fun. and your funny.

 

[whoaru99]

Huh? What's the big argument? The mfg. instructs to rehydrate. Seems pretty clear cut, eh?

You'd think so, but this thread has proven otherwise!
