Polyclar

[Ross]

I've been having real problems with chill haze from Bairds Maris Otter. The last 3 sacks have gone from producing beer like Brisbane River water (muddy), to clear, & now back to a strong haze. Other local brewers using the same malt, have had exactly the same results. I've included a protien rest, but to no avail...

This last sack caught me off guard, as after the 2nd one being fine, I just put it down to a rouge sack & filtered/carbonated the last brew without checking for clarity.

Anyway, the main reason for the post - on reading up more on Polyclar http://www.ispcorp.com/products/beverage/ I've found that my hbs had not properly explained it's use to me - I was under the impression that it needed to be added to a brew for several days to work, where infact, all it needs is 10 minutes, as long as you have the ability to filter your beer. The 1 micron filter removes it perfectly - so if you have identified your beer as having chill haze & wish to remove it, the process is quick & easy - I removed all haze from my Summer ale on tap last night, in under 1 hr & back to drinking it.

Apart from the aesthetic appeal, chill haze is not good for the long term stability of your beer & IMO is best removed...

Edit: Polyclar benefits your brew in many ways - the link above will explain for those interested...

cheers Ross...

Here is the extract from the site, it is a bit hard to find.

Single Use Stabilizers -
Polyclar 10 and Polyclar Plus 730
1. Ensure drum contents are thoroughly mixed, eg, by rolling the drum.
2. If utilizing less than a full drum, weigh out the required quantity of Polyclar PVPP powder, avoiding dusting.
3. Slurry the powder into softened de-aerated water in the dosing tank with continuous stirring.
4. Continue stirring for at least 15 minutes, preferably 60 minutes, to swell and hydrate the stabilizer. The slurry should then be kept under constant agitation.
5. An inert blanket of CO2 or nitrogen may be used in the dosing vessel to minimize oxygen pick-up. One of two methods can be used to do this:

Dosing by Continuous In-Line Method
6. Inject the Polyclar slurry into the beer stream using a proportioning pump. To ensure homogeneous, uniform contact with the beer, inject the slurry over 90% of the run.
7. A contact time of 5 - 10 minutes is required from point of injection to point of removal of the spent Polyclar PVPP on the filter.

Dosing by Batch Method
6. At the beginning of the filling cycle, inject the Polyclar slurry into the beer stream en route to the finishing tank.
7. A contact time of 5 - 10 minutes is desirable, however there is no negative impact on the beer with extended contact times, ie. several days or more in the storage tank.
8. If the Polyclar slurry is added to a full beer tank, the contents should be thoroughly mixed, eg, by recirculation, to ensure thorough dispersion into the beer being treated.
9. The spent Polyclar PVPP is removed mainly by settling in the finishing tank followed by complete removal on the DE filter.

Hoops,

From QHB at Underwood, but I think they are out of it now. I need to find somewhere else until they restock...
Anyone find some in Brizzy, please advise...

tut tut
Bairds Maris Otter must have quality control problems again :blink:

Time you swithed too some Powells malt Ross

Batz h34r:

 

[AndrewQLD]

there can't possibly be anything wrong with the Bairds product Batz, they have very strict quality control unlike some others :lol: and their product is ALWAYS perfect .

Ross can't help you with the polyclar, sorry.

Cheers
Andrew

Makes you lament the loss of Thomas Fawcett's Marris Otter. That was particularly well-behaved stuff. :beerbang:

Have to agree with you there Warren - Never had a touch of haze in over 50 brews using it -

Never really given the Aussie pale a fair go, time to do so I guess...

Ross, thank you for the excellent write up as usuall. A cuple of months ago I got some Polyclar from my club (BABBS) and I am very happy with the results. Unfortunately they also ran out of stock...

Cheers,

Is long term stability really important in your brews, Ross?

In some beers yes & in others no... But anything that helps keep the beer at its peak has to be welcomed...

I use almost solely JW malt but have never used the ale as I just use the pilsner as a base. The last apa I did (and the only ag APA, i am a dark beer drinker) ended a little light in 'maltyness' and I was thinking of splitting my base grain orders between the pilsner and the ale to allow for apa's. I have had no problems in pilsners or dark beers and so hadn't thought I would have trouble with the trad ale. I would be interested in any problems people have had with this grain as I will probably buy a few bags in the near future.

Just filtered an American Ale this morning made with MO (chill haze problem) as the base, that had been dry hopped with 50gms of pellets for 5 days - 3 days at room temp & 2 days CC - polyclar added last night...

Picture tells all...
