Title: Polyclar Brewbrite
Post by: narcout on October 19, 2016, 04:19:03 pm
To anyone here using this stuff, how are you using it?  What do you think?  Does it require downstream filtration to remove?
Title: Re: Polyclar Brewbrite
Post by: zwiller on October 20, 2016, 03:18:07 pm
15g/hL (or about 3 grams per 5G) rehydated in cool water added at 10m to KO or halfway in whirlpool.  Love the stuff.  I personally think it will wipe the floor with brewtan.  No need to filter as it is not harmful: PVPP is the stuff pill coating is made of.  The reference to filtering is only to comply with RHB.

Thanks, I may have to give it a try. 

It might work well in conjunction with Brewtan since, as I understand it, one works mostly on proteins and the other on polyphenols. 

Is there a US source, or do I need to order it from Australia?

Is polyclar more for clarity or does it help to drop tannins too?

It works quite well on it's own, but you're correct that Polyclar attacks PP.  No retail outlets for it here but my rep told me most breweries would hand out a little to the adventurous homebrewer.  Myself, I got the real deal but I spent a year using what I reverse engineered: 2.4g LHBS polyclar plus 1/2 tab whirlfloc.  I really think it's the same.  I have a few buddies that ran tests of their own on this and agree.

Yeah, I spoke too soon on getting some. Hadn't checked my email for several days and ibrew had sent me a message saying that they discontinued Brewbrite in favor of Brewtan. So they'll just send me extra Brewtan instead evidently. All good.

The reason it improves clarity is that it removes tannins/PP.  To be "clear"  ::)  Polyclar Brewbrite is a mix of whirlfloc and polyclar(PVPP), polyclar is just PVPP.

I might try that blend, but there are different grades of Polyclar. I've used Polyclar VT, the coarse stuff that settles out nicely in the fermenter. I assume this is the one you use?

I use actual PBB now but not 100% sure what polyclar I used previously.  It was LHBS Crosby Baker "polyclar".  Honestly, I don't think it matters as the lower weight stuff is probably not available to homebrewer.  That said, the various formulae of polyclar is confusing.  RDWHAH

I don't think Brewtan and PBB are similar AT ALL http://community.mbaa.com/HigherLogic/System/DownloadDocumentFile.ashx?DocumentFileKey=1785a2cf-0d9e-4a58-b298-7df3965f3e67&forceDialog=0 (http://community.mbaa.com/HigherLogic/System/DownloadDocumentFile.ashx?DocumentFileKey=1785a2cf-0d9e-4a58-b298-7df3965f3e67&forceDialog=0)

Thanks. Yeah, I was kind of thrown that ibrew would discontinue Brewbrite in favor of Brewtan - Brewtan is great but, as far as I can see, bears no resemblance to Brewbrite. They would seem to coexist nicely. Who knows, I may make some.

Coexist > very true: I would have to dig for a cite but you already posted "The Ultimate" and this parallels studies.  Brewtan in mash and PPB in boil FTW but like I said, I think PPB will wipe the floor with Brewtan in terms of overall results/impact.

NICE PAPER!  I will have to read later.  There are many ways to skin the cat…  The key is to find out what works best for you.  Remember, nearly all these studies are on megaswill. 
This reminds me to point out 2 things: First, PPB dosing is beer dependent.  Higher ABV/Higher IBU gets more.  Secondly, do not use PPB within 5m of any hop addition.

Title: Re: Polyclar Brewbrite

Brewing literature claims excess potassium in the mash is detrimental. Thats how sodium was chosen. Potassium is fine for cold side.

In your post on colloidal stability in the last highlighted section it says the use of vitamin C used on it's own at packaging can be detrimental. I just bottled a batch with Vitamin C only, so we should add some SMB with the V-C at packaging, what do you do? And what is dhydro -asorbic acid, and what are it's affect?
Title: Re: Polyclar Brewbrite
Post by: zwiller on October 27, 2016, 08:27:21 am
+1;  I plan to fool with SMB/PMB but have not yet so no personal experience.  I have been using ascrobic acid at kegging along with PPB in boil and I have really good stability but the real test would be IPA where there is dry hopping but have not brewed one yet to test.  In my experience, PPB alone works great so long as no dry hop.  A buddy of mine tested a PA where PPB was added halfway in whirlpool and said no hop fade after 6mo.  I agree but never had a keg last that long.  An interesting side note: on another forum someone sent HT/NEIPA to Ward and the K was off the charts!  While K is normally present in beers, a few knowledgeable folks thought it was out of range and I am now seeing a correlation to higher level of K, LO brewing, and dry hopping: PMB or maybe AntioxC which has PMB.

Antiox-c for the win there. ;)

In the packaging phase, SMB, and Ascorbic acid(AA), react differently. SMB is a fast reactant, where at AA is slow. SMB will try to quickly eat up o2, and use itself up first, once that happens and the smb is all used( say dry hopping or beer transfer), AA will hang out and try to mop up any slow ingress(say impure co2). I think the problem lies with AA alone trying to combat a large fast ingress, it will basically super oxidize itself. BUT I am by no means a chemist, so you may want to fact check that!
Title: Re: Polyclar Brewbrite
Post by: zwiller on October 27, 2016, 10:09:20 am
Matches what I've learned.  To get us back to PPB, none of these O2 scavengers remove polyphenols (PP).  Only polyclar does and if your beers are a bit harsh and you think PP are the culprit, PPB will help.  In my brewing, I found a noticeable difference using PPB.  Dare I say it gives a "polish" to the beer.  While there is a reduction in bitterness, it is a reduction in the harshness of the bitterness.  The clarity is also a whole other level.  Honestly, I care less if the beer lasts longer using it (but it does).

I can honestly say that I haven't experienced any super oxidation with AA. But I've used it mostly in an attempt to protect hop aromas from oxidation in hoppy styles and feel that it definitely helps. So I'm assuming that time is the X factor as these beers obviously get consumed young and quickly. I am curious about its potential in tandem with SMB as was mentioned.

 As a plug for Brewtan, I will say that there definitely seems to be a connection to improved shelf life (just anecdotal, no triangles). I medaled with a Marzen in a fairly big comp recently where I used Brewtan, and the beer was over 3 months old when judged. Granted, not over the hill by any means, but past what I would normally consider to be its absolute peak flavor. Except it tasted very fresh at that age. Gonna keep using it in tandem with some of these methods.

I'm going to try this today, methinks. It sounds like an avenue to cram more hop flavor into a beer before it starts to get harsh.

Does this sound like a reasonable approach to this?

3 gallon batch, 6 ounces of whirlpool hops added at 170F for 60 minutes

30 min into whirlpool: add 3g Polyclar VT (rehydrated) and 1/4 tab of whirlfloc

Or should I consider more Polyclar because of the amount of hops? Is there harm in overdoing the polyclar?

I just used some Polyclar in tandem with 1/2 whirfloc tab over the weekend (10 mins) at a rate of .5 g/gallon, ie., 2.5g for my recipe. It's at the low end of the range, so I want to start there. I used Polyclar years ago at the LHBS recommended amount which was higher (don't remember the exact dose unfortunately) and felt that it stripped away some flavor. So I want to start out at the low end and assess gradually.  I'm curious to see how it comes out.

Finally, someone gets it...  Your plan sounds good since a 3G batch.  Not sure if it was mentioned but polyclar's effect is physical, so be sure and stir plenty.  I deliberately used much more a few times and found no ill effects.  I think there is a point of diminishing returns after a certain point you are just wasting it.  Best of luck! 

I too also found polyclar "stripped" flavor years ago but have come to realize I now like the effect.  To me, it removes the grassiness/vegetal/harshness of the hops.  Some could argue it takes some of the "freshness" but I digress.   Notice any better clarity in cast out wort?  Mine was substantial.

Not yet, it was mentioned over at GBF that one could possibly reverse engineer using sulfite test strips.  Personally, I hope AA gets me a another week or 2 on it's own.  I am apprehensive about adding something that creates sulfur (at kegging) even tho the science is good.

There's  a similar product called Aromax: http://www.aebafrica.co.za/antioxy/AROMAX_depliant_inglese.pdf

The Super version contains:
50% potassium pyrosulphate
35% ascorbic acid
15% gallotannins

For wine, utilization is 20 g/hl. This increases  SO2 by 54 mg/l. If we cut this in half for beer, the SMB and BTB amounts match low oxygen and BTB recommendations. So we get to 10g/hl SMB, 7g/hl AA, and 3g/hl BTB.

The regular version contains 50% SMB and 50% AA, also 20 g/hl.

That's not good.  I am a little concerned about adding SO2 causing compounds post boil.  On the other hand, wine uses much higher doses and generally has no sulfur flavor, so will probably do my own trials.

I'm looking at this mostly for dry hopped IPAs, and possibly for bottling them as well.

Spunding makes great sense but not for IPA/dry hopping.  Cold crashing and DH on bright beer has been the largest improvement I've made in a long time to my IPA and kinda nixes it.  As of now my thoughts are basically, MAYBE adding KMB/SMB at dry hop giving it time to dissipate and AA at kegging.  Might consider sugar carbonation too.

Definitely clearer wort today, but there was also a lot more big, fluffy trub as well - way more than Whirlfloc alone. I probably lost an extra quart more than usual to trub. No biggie, but I'll definitely plan for it next time.

The theory is that when using PPB the break should settle and compact much more than typical so there is actually a gain but I am not sure that scales to us homebrewers.  I don't rack off trub and just dump it all in fermentor and never really noticed any gain or loss.  Also interesting, they have proven fermentation time is reduced (faster) when using PPB.  Main thing I notice is that it seems there is rapid maturation and beer gets in the tasty zone fairly quick.  IE usually there a period of time where an IPA is grassy...  Since the grassy polyphenols are removed via polyclar, there is no wait.  I think this also dramatically affects lagering times too.

While this isn't PPVP related I have employed a hot trub separation and a cold trub separation for quite some time now and my beer going into the fermenter is crystal clear. I  have found this dramatically accelerates conditioning times, like by weeks. So I will agree with break materials and polyphenol removal as well..

Ascorbic acid alone is basically poo-pooed by every technical source I have seen it in. Here are some quick references.

Yeah, the wort was very clear. Looking forward to the end result. I should've posted - I used .5g/gallon Polyclar 10 (the low end) and 1/2 tab whirlfloc for 5.5 gallons wort.

All I'm finding are Polyclar VT and Polyclar 10 (not even sure if they are different).

The directions for both are to add post-fermentation, which I have no interest in.  Can either of these be used successfully in the boil?

IIRC zwiller posted that he has made his own Brewbrite using typical LHBS Polyclar. I did the same using Polyclar 10 and 1/2 tab whirlfloc and added the mixture @ 10 mins left in the boil.

Correct, however I have the real stuff now.  No difference, really.  I researched polyclar VT vs 10 in the day and was equally confused but I will say if you go to the MFR site (Ashland) there is no mention of VT just 10 if that helps.  Honestly, don't think it matters.  I think I've posted enough papers to confirm adding polyclar to boil is a non issue.

Some data for you guys.  PBB is 60:40 polyclar:WF.  I use 8g PPB for IPA.  For DIYBB, that is 4.8g polyclar and 3.2g WF.  Like you guys we started low and worked up.  My buddy did the extended aging testing and I did the higher dosing testing  ;D  Do recall dosing is gravity and IBU dependent also the recommended dosing is likely for megaswill.

Bringing this back from the dead.  How were your results with the homemade Polyclar Brew Brite mix?  Was there a noticeable difference in hop harshness with a big (pellet) dry hop?

I like the mix for producing very clear wort and beers that don't have young, 'green' character, not so much for effects on hop character. Since it's added late boil, it wouldn't have much effect on dry hop character. It does reduce hop intensity a bit on beers where I whirlpool hop heavily. Some would say makes a smoother hop flavor, I say reduces the flavor a tad. I hop IPA heavily enough to not feel it's a negative.

I know this a very old post, but I've been interested in giving Polyclar Brewbrite a try and I'm having exactly zero luck in locating a source for it. Anyone have a source for buying it in non-industrial quantities?

I did not have any luck procuring actual Polyclar BrewBrite so I went the DIY way using Polyclar VT (PVPP) and Whirlfloc.  I use a 74% PVPP / 26% Whirlfloc, and aim for 2.3-5.7 grams per 6 gallons at 10 minutes left in the boil.  The dosage is dependent on recipe formulation (to some extent), and I haven't yet determined what kinds of beers need what size dose so I've opted for a middle-of-the-road dose of 3.6gr in most beers.  Finally, in all honesty, I cannot confidently say that it's doing much.  It may be, but it may not be also - I just can't determine but I continue to use it  :o.  My hope is that it's binding up some polyphenols in the fermenter and/or keg, and dropping them out of solution so that they don't have downstream staling/oxidative effects.

Ok, I just got some ployclar 10 ordered. When you used it, did you crush up the whirlfloc and make a combined powder with it, or did you keep and add them separately?

Thanks for the guidance!

I've recently been using Super Moss HB and haven't been particularly impressed with it.

I break up the whirlfloc into smaller bits and powder, and then I put the PVPP on top of that in my bowl.  I don't try to mix those two together though because the PVPP is super light and almost wants to take flight.  At about 12 minutes to end of boil I mix in about 1/2 cup of boiling wort in the bowl and stir it into a slurry, then add it all back at 10min.

I also have a container of SuperMossHB that basically goes unused because it SUCKS! ;D  I swear that it somehow makes wort MORE cloudy and helps to keep stuff in suspension.  I don't know how it could be so drastically different than whirlfloc but it is.  The only time I've used it recently was once when I wanted some kind of kettle fining and I was out of whirlfloc and irish moss.

Pretty much the same thing I do.

Well, can't wait to give it a shot when the polyclar shows up.

Funny, PBB acts just like starch and clumps up bad when using hot liquid.  I use room temp distilled.  Haha, the stuff IS super light!  Do NOT try and measure it outside  ;D

Supermoss never worked well for me either. 

Very interesting not many really are impressed it.  Myself and buds were quite blown away.  In the day I almost approached a friend who owns my LHBS to get him to be the first homebrewer retailer.  He is an amazon reseller.

I've been really impressed with diy brewbrite. I've been doing what Hoosierbrew suggested above .5 g per gallon pvpp and 1/2 wf tab for 5.5 gallons. My wort has never been clearer leaving the kettle and my beers have also ended cleared in gereral. Not sure id use on every beer style but I think it gives me positive results for lagers. I've noticed my post boil gravity sample has a smoother flavor, less of a typical pre fermentation harshness. I haven't compared batches with and without but for my lagers I am going to continue using it.

I've noticed similar results myself, although again no side-by-side comparisons on my part either. I'm a stovetop small-batch brewer, and I just pour from my kettle into my fermenter. I've noticed that I have a lot more clear wort on top before I start hitting the fluffy stuff as I pour.

Well, I finally picked up some PVPP and am going to try it out tomorrow.  Think I will go with 3 grams of PVPP and 1/2 tab of whirlfloc.
