No Chill Experiment

[brewt00l]

Well, with beer as clear as seen in the photo, I am not sure that there are more protiens existing in my no chill beers than there are in traditionally chilled beers. I mean, if there were, youd be able to see signs that they actually existed at 34F. Wouldnt you?

I'd suspect as such but would still be curious. From what I understand, chill haze is the result of numerous factors and not just your chilling process...made up of proteins and tannis extracted in the mash, impacted by your boil intensity & chilling method, that bind together at lower temps to be visible.

Course, if your kegging and have your keg in the fridge for a period of time to carb/condition, those proteins and tannis are going to bind and drop, you've already precipitated the haze out of the beer & keg with those first couple pulls.

Is that a kegged sample?

Yes it is a kegged sample... but a bottle sample would be the same, of course unless you pour all of the dregs out into the glass too, wouldnt it? I mean I used to bottle beer, and it still came out this clear, as long as I didnt pour all of the dregs out.

TW states that if you do not have a good cold break, these protiens will NOT drop out later when the beer is cooled, leading to chill haze.

Since there is no chill haze, the protiens went somewhere, and TW sayes that it shouldnt. Even my traditionally chilled beers, are hazy for a week or two in the keg until the crud drops out, it is inevitable. The no chill beers cleared the same, that is all I am saying...

Depends...When many people bottle, they keep them in a room temp place to carb and condition for a couple weeks. A handful of bottles hit the fridge at a time for consumption while the rest sit at room temp. How long are these beers generally hanging out in the fridge at temp? Many brewers who don't keg do not have the fridge space to keep entire multiple batches chilled from the time the beer is packaged through consumption.

We have a radically different takes on this TW stuff. My first AG beer had chill haze (mash technique issues and no kettle finings). If the bottles were kept in the fridge for a few weeks before opening, they didn't exhibit the chill haze.

...not trying to invalidate this method, just trying to understand it fully.

 

[The Pol]

Keg has been in the fridge for 4 weeks...

Takes time to carb. and condition.

My point is... so it takes 4 weeks to clear in the keg... it took just as long for my traditionally chilled beers to do the same, even when they were bottled.

 

[brewt00l]

Here's some departure with TW from BYO:

The clumps are slightly heavier than beer, so if the beer is kept undisturbed at refrigerator temperature for a few weeks, it will become clear again as the protein settles to the bottom of the bottle.

But what I'm saying is that your results don't necessarily prove that your no-chill beer didn't result in no chill haze since it had the opportunity to precipitate in those 4 weeks.

If someone bottles and doesn't keep them in the fridge for weeks before consumption, their results may be different.

Okay... I have time to say this one more time, as I have things to do.

The concern has been that any HAZE will not precipitate out, that the final product will be HAZY because there was no cold break.

My point is, the end product, looks and tastes the same.

If there is extra "haze"... it never makes it to the glass, because like all haze, it still precipitates out. The end product, for those that like crystal clear beer, is the same.

I used to chill my wort, so I am fully aware of the clearing process with chilled wort. My point is, this stuff takes no longer to clear, and is ultimately just as clear... as the chilled worts. Whether it STARTS OFF with more haze, would be hard to quantify. The concern for many who do not no chill thier wort, is that the beer will remain hazy... but it only remains hazy as long as a traditionally chilled beer will.

Again, the point is that the proof you offer with that glass that no-chill brewing results in crystal clear beer w/o chill haze is invalid.

How is it not? Does that glass have haze? The concern, again... since I have repeated it like 4x... is that the beer will not clear. Apparently, it does. I never said that it NEVER had chill haze, and if you thought that was the point... well, I cannot help you. All HB has chill haze, the myth is that no chill, wont clear as others do. Apparently you missed the other debates? This thread never said that "no chill beer results in crystal clear beer", that is laughable. It stated numerous times that "no chill" beer DO clear, contrary to popular belief.

All normally chilled beers have haze, until they are chilled for a period. No chill, is no different. People have been told that no chill beers will NOT clear... apparently the 80's paperbacks are wrong.

It may begin with more protiens than normally chilled beers, again, that cannot be quantified. But the end product can be... because they both end up clear. The myth that no chill beers will not clear in the same time/temp frame that chilled beers will, is false.... wholly false.

Again, point to where I EVER stated that "no chill resutls in crystal clear beer"... I challenge you.

I agree - and before anyone accuses me of being cynical, let me put that to bed right now.

I appreciate that there is lots of experimentation with no-chill, but the contributing factors to chill haze are complex and often compounding, much like those regarding DMS formation. While cold storage does encourage the precipitation of proteins in ridding chill haze, rarely do bottlers store an entire batch in such a manner. The bottles are warm-conditioned, then popped into the fridge a few days or week before consumption. If there's chill haze to be had, it's going to show up in those circumstances. Under that scenario, a kegger has a bit of an edge in combating chill haze.

I'm more interested in the long-term stability of no-chill beers, as chill haze isn't just an aesthetic issue; unprecipitated tannins and proteins can also contribute to premature staling. Now, I'm not suggesting that all no-chill beers will suffer but it may be a worthy experiment for someone to undertake.

 

[The Pol]

Dude, I am still reading my posts...

Cant find where I said "no chill results in crystal clear beer".

I think the only statement that I DID make was that the end product, looked the same.

This is why I spend less and less time on this board. You write one thing, and people decide to make it into something else that they can bi## about.

Keyboard commandos, you have the stage.

 

[flyangler18]

Cant find where I said "no chill results in crystal clear beer".

The picture you posted of a 'typical' no-chill beer suggests that.

I'm not taking anything you said out of context, and I don't believe brewtool is either. I'm just interested in having a thoughtful discussion.

 

[ohiobrewtus]

I want to know why you're drinking your beer at BMC temps!

 

[brewt00l]

I think we all agree that chill haze participates out with cold storage, end, and can move on.

 

[The Pol]

Um, well if saying...

"typical no chill beer" translates into... NO CHILL "creates" haze free beer. Then I am guilty of making hanus claims... you are right. Although, I think that you are inferring MUCH more than I did. Still, I am guilty, my bad.

I was simply answering a question that has been posted in numerous no chill threads, where brewers were under the assumption that no chill beers WILL NOT clear. The actual concern was that the no chill beer would could not finish as clear, and therefore not be aesthetically pleasing. I posted this photo in that thread as well. There I go, trying to answer questions again with practical useage of technique.

Read from post #250 on... this is where the whole issue of the aesthetic properties of no chill began. Thus leading to my post here as well, since there are two major "no chill" threads running concurrently.

 

[The Pol]

As far as the science behind this sort of thing. Well, I am no scientist... but if I were my facts would not be based on theory alone. There would have to be experiments and data sets of course to justify any assumptions that were made prior.

Like I said in the other thread. I began this "no chill" thing just to test it... to see if it was viable. I have been doing it for 4 months, so that is as far as my experience goes. If anyone here has more time doing it than I, Id welcome thier input.

I have done charts for hop addition compensation. And I post only my own physical findings. I am no scientist, never claimed to be. I have read the books, I know what they say... and would have NEVER imagined doing this with my HB two years ago.

Long term stability... good question. Until there is a test run off the same batch, half chilled and half no chill, there will not be any physical proof either way. Most of my kegs are kicked within 4 months of the brew date, so that is as far as they get.

Is long term stability an issue if he protiens and such drop out, as they do in normally chilled beer? Is it more of an issue in bottled beer than in kegged... since the keg get cleared of these compounds when tapping the keg?

Good questions. There are just not enough people actively trying to find answers to them. If there are questions asked, and I have practical experience with them, then I will answer. I dont get on these boards and claim that anything is a fact, unless I have tried it. There is a lot of mis-information on this board, and plenty of "repeating what the other guy told me". I do not want to get into that... I only want to discuss facts. Anyone can specualte and be a "pro" speculator... but that doesnt yield results, because there is no physical evidence, otherwise it wouldnt be speculation.

JMHO

 

[yeoldebrewer]

The proof is in the pudding.

If no-chill turns out to work, everyone will be asking why it wasn't done years sooner.

Well, it is like a lot of things, I suppose. Incomplete understanding of a process, which leads to mis-information, which is then perpetuated because you know, if it is in a book, it HAS to be true.

Legitimacy is given to things in print and such. Why people are not more skeptical of what they read and hear, I dont know. My neighbor swears he was an expert landscaper, why would I take his word for it? His lawn looks like hell. See what I mean... anyone can talk, but few have the physical evidence to back it up. Read the threads, you will see.

 

[roylee]

I'd submit that no chill was done years ago. Anyone wanting to read a lot more about it can do so on the Aussie Home Brew forum. And thanks, Pol. I had a glass (OK, two) of no chill last night . . . . the timing of hops additions you suggested worked quite well.

 

[flyangler18]

For purposes of discussion, what styles (and relatedly, the grist) have been successfully brewed utilizing the no-chill method?

It seems that everyone is fixated on clarity, but what about long-term stability (for beers that continue to mature like barleywines)? Given that the vast majority of HB is consumed quickly (say, within 2-3 months of brew date), I suspect that we're not getting a complete picture.

 

[The Pol]

I think two guys asked about clarity... I dont know that anyone is fixated on it. It was like the concern about botulism, the DMS scare... etc. Basically everything one could be concerned about, people are concerned about.

Id submit that if you really want an answer on long term stability and historically what no chill does to different beer types, you are better off on the Aussie threads. Unless someone wants to start making unsubstantiated statements (no not on HBT... never) I dont know of anyone here with that sort of experience with no chill.

I dont think anyone here has been using it more than a few months... since that is when it first hit these boards.

 

[The Pol]

I can submit that I have used no chill on an APA, IPA and Blonde ale...

I am personally disgusted by dark beers, so I never brew them, someone else would have to chime in there.

I also rarely brew anything over 1.070, so again... I dont have that expeience, nor will I ever.

This being said, my beers last 3-4 months.

 

[bakins]

I did a brown ale - is good.

I did a strong saison @ 1.083. it's still in primary, but will know in several weeks.

My oldest no chill I'm still drinking is a red wheat, but it has lots of the wheat beer taste that tends to cover up some issues, so it's not a good judge.

 

[The Pol]

Should I brew my haus ale and let it sit for a year or so?

 

[flyangler18]

Your haus is, what, around 1.040? I don't think that is the right beer for the job. I think you need something considerably higher gravity that will age gracefully - a barleywine, RIS, Quad, BGSA, etc.

Im not looking for graceful, I am looking for something that wont cover flaws with strong characteristics. If I brewed a BIG beer and let it sit a year, I can hear it now... "that is invalid because that beer has such a strong character that it could cover up changes in the stability etc..."

This is why my first no chill was my huas ale... because something simple and clean is much easier to find flaws in.

 

[flyangler18]

But how could you attribute any potential degradation in flavor or character simply to the no-chilling part of your process? There's too many variables unaccounted for. A year-old 1.040 ale isn't going to age well, regardless of whether you chilled or not.

The more I think about this, I'd say a lager would be the best backdrop for this kind of testing - maybe a Pilsner.

But wouldn't you have the same problems with a pilsner? I am under the impression that any lighter beer would not age well, Lager or Ale. Anything that is kept refrigerated is not likely to exhibit the flaws expected.

What would be nice, is a split batch, one chilled and the other not. THat way you have a direct comparison.

 

[flyangler18]

I think if you brewed a Pilsner to a slightly higher gravity, say 1.060 -1.070, it would have better potential to age well without severe flavor degradation, though any hop flavor and aroma would be greatly diminished as expected. A low-gravity session beer would suffer greatly from extended aging; doing a split batch would be the only way to truly test this hypothesis.

This is an interesting dilemma to try and reason through!

 

[The Pol]

This defies all reason, we need experimentation... sweat equity.
