Hello!
So after I chilled my wort I forgot to add White Labs Clarity Ferm. Of course its directions state:

Quote:

Add to cooled wort at the beginning of fermentation

So does anyone have any experience with adding this after a week into primary? Or any advice, thoughts.. anything

I'm not broken up about it but it is a kolsch and when someone wants to try one of my beers, I do like it to be clear.
Thanks!

I would save it for the next batch. Doesn't that thing break down sugars?

the brewing network had a sunday session a while back and they talked alot about clarity ferm with the whites.

its my understanding if I remember correctly, it works best if added prior to fermentation but will have positive effects as long as you add prior to cold crashing or chilling.

Maybe too late for clarity ferm, but you're right on schedule for some gelatin finings...

Clarity ferm will work post fermentation it just takes a lot longer because it's not being churned around by the fermentation process. The trick for post fermentation is to keep the fermentor warm. I had a slightly hazy tripel two weeks ago in my coldish garage, I added a brewbelt to it and the beer was brilliantly clear when I bottled on sunday. So you can add it post ferm it just takes a little longer and needs some warmth. This is my experience at least.

Remember it's a protease enzyme that breaks down haze forming proteins which happens to include gluten to an extent. It doesn't need fermentation to work but it sure helps out because of the exothermic nature of the ferment making it easier for the enzyme to do it's thing.

hmmm... ok, so here's what is going on... I was out of town and just got back last night, the airlock was percolating slowly (a week in) but my place was a little chilly so I turned the heat up to 70F... the next morning I woke up to a see that the krausen had gotten so big it was blowing into my airlock and clogging it... of course i replaced it so I'm going to go ahead and add some clarity ferm as I am going to leave it in primary for 3 more weeks.....

Just make sure the beer is nice and clear looking before you bottle because it will clear in the bottle otherwise depositing all that chewed up protein at the bottom of the bottle.

To several batches, I added Clarity Ferm 7days after adding to the fermentor and got excellent results. The batch passes the gluten tester.

A couple of the batches were a mix of sorghum malt and barley malt and grains. The beer was very clear esp'ly considering that it is a Sorghum malt with roasted rice for flavoring. Normally these things are as cloudy as mud. I typically ferment for ~3weeks total and then bottle.
