Worthog Posted December 30, 2018 Share Posted December 30, 2018 Today I bottled my first batch clarified using Polyclar pvpp, pitched the second day into my cold crash. I bottle at 0-1c, so I was looking for chill haze. The bottles seemed fairly clear, probably more so than the simple cold crash clarity I have had in the past, but the proof will be in the glass in a few weeks time. An interesting change in the FV trub left behind; The bottom of the trub was more solid like a crepe you could roll up. Never had this before so I'm assuming most of that teaspoon of pre-stirred 'plastic dust' remains there, in that trub. I still swirled the top part and tapped it into a PET as my next US-05 yeast slurry. I'm hoping the Polycar won't affect my yeast harvest. Is that likely to be so? Cheers.

Otto Von Blotto Posted January 4, 2019 Share Posted January 4, 2019 Polyclar has no effect on yeast so it shouldn't cause any issues with harvesting. Interested to see how much effect one teaspoon of it has on the clarity. Link to comment Share on other sites More sharing options...

I figured that a rounded teaspoon of Polyclar would be 5-10gms, which is approximately the suggested dose for 23L of beer. What measure do you use Kelsey?

Otto Von Blotto Posted January 6, 2019 Share Posted January 6, 2019 I weigh it with scales, and 5-10g is a fair bit more than a rounded teaspoon which is about 2-3g. Volumetric measurements are useless for weight because the same volume of different things will weigh different amounts. For instance, a heaped teaspoon of sugar will weigh more than a heaped teaspoon of Polyclar. Link to comment Share on other sites More sharing options...

Interested to see how much effect one teaspoon of it has on the clarity. Result with 1 rounded tsp of Polyclar Pvpp. Definitely an improvement over just kettle Whirlfloc and simple cold crash after fermentation. Estimate 3g of Poly to 23L batch. My next batch will have been treated with 9gms. I will post a pic when beer ready. Cheers Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted January 15, 2019 Share Posted January 15, 2019 Done pretty well there. I just added 9-10g to a 20L batch of pilsner a few days ago. Bit more than I intended but I'm sure it won't do any harm. Will probably keg it this coming weekend and continue its lagering in the kegerator while the next batch ferments and then goes on tap. Should get it at least another 5-6 weeks lagering on top of the 1.5-2 it's had in the fermenter. I expect by then it will be clear as water.

Worthog Posted January 27, 2019 Share Posted January 27, 2019 I'm getting no chill haze using the Polyclar but I still get cloudiness in the second glass poured due to the pouring action stirring up some superfine cloudiness - not any dregs. It seems to improve if the bottles are chilled for several days, but it is still there. Any other ideas for fixing this? Cheers Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted January 27, 2019 Share Posted January 27, 2019 It would be part of the dregs getting stirred up but obviously not very much of them. I use isinglass to drop yeast out before I use polyclar, it seems to result in a really compact sediment in the fermenter, and I get hardly any in the kegs. It may help with reducing that bottle sediment and keeping it compact, however I think time in the fridge is the best way to keep it compacted.

Worthog Posted January 31, 2019 Share Posted January 31, 2019 3 rounded tspns of Polyclar in 150ml of boiling water, cooled and mixed into 22L, is giving me unparalleled clarity. No taste effects that I can tell. (Sorry Lusty). Above is a 4.2% ABV Pale Ale (citra). Cheers Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted January 31, 2019 Share Posted January 31, 2019 That's what I like about polyclar, no effect on flavour that I can tell, but removes chill haze while dropping harmlessly into the trub. Link to comment Share on other sites More sharing options...

Otto Von Blotto Posted January 31, 2019 Share Posted January 31, 2019 I've used polyclar in stouts before. The way it works to improve clarity also helps lengthen shelf life/prevent off flavours developing. Obviously I used it for the latter reason in those beers.

Ha ha yeah, I get that, I was just kidding but the brew today being the red rye, will get the treatment as I’m sending it to a celiac Link to comment Share on other sites More sharing options...
joolbag Posted January 31, 2019 Share Posted January 31, 2019 I've been meaning to try this polyclar for some time. Who sells it? Is it know by another name? My two local brew shops don't have it. My regular online shops don't either! Why is it so hard to find track down for me?! Link to comment Share on other sites More sharing options...

Craftbrewer sells it, that's where I buy it from, though obviously not local to you. It usually does have polyclar in the name though as it's a trademark, sometimes preceded by PVPP. I'll have to check the pack but I think mine is called polyclar VT. Link to comment Share on other sites More sharing options...

Worthog Posted February 13, 2019 Share Posted February 13, 2019 So the actual dose of Polyclar is not specified with the product. The sales doco does say you may require more in a Pale Ale than you would in a dark beer. I have now established that 2 x rounded teaspoons in 150ml of boiled water, cooled and poured around 23L of beer, 3 days into cold crash, will provide the pictured above level of clarification in a 4kg AG Pale Ale. No hint of chill haze. Cheers Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted February 13, 2019 Share Posted February 13, 2019 On the packets I get it says 5-10g per 23 litres. I figure you'd use more in a pale ale as there's probably more polyphenols in them from the hops, but whatever the case I'm also happy with how it performs. Sometimes it doesn't completely clear it up but it's a lot better than without it. Link to comment Share on other sites More sharing options...
Worthog Posted April 11, 2019 Share Posted April 11, 2019 I have just tested 4 batches with Polyclar PVPP, followed by 4 batches without. The PVPP definitely makes the beer look good, per pic above, and eliminates any chill haze. Taste testing may be a little subjective, like the difference in taste between PETs and Glass, but I have decided the non PVPP beers tasted better, with better hop aroma (maybe flavour also) and a more fullness of taste generally. I also thought I could detect a 'texture' associated with dustiness - don't laugh, it seemed real even if cognitive only. So I have dropped Polyclar PVPP for my ales, but may use again in Lagers only. Cheers Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted April 11, 2019 Share Posted April 11, 2019 Fair enough mate. I didn't notice a difference in flavour when I started using it. Maybe my palate is a bit ruined by years of smoking Link to comment Share on other sites More sharing options...
