CellarScience® SilaFine | Beer Fining Agent

Please select from the following option(s) to see pricing and availability.

SilaFine is an easy-to-use, vegan friendly fining agent that quickly creates crystal clear beer by removing yeast and haze-forming particles. This highly effective clarifier will eliminate or greatly reduce the need for filtration without affecting flavor. SilaFine is a unique, negatively charged silica sol fining agent that binds with positively charged haze active proteins and polyphenols to create an electrostatic net that also drags down yeast cells. SilaFine does not target foam active head forming proteins, so the beer foam in glass is unaffected.

Add 10ml or 1 tbsp per 5 gallons of finished beer. Gently rouse the beer to fully disperse the clarifier. SilaFine will work to drop out yeast at fermentation temperatures, but for full effectiveness on haze-inducing particles, we recommend adding it to beer that has been chilled below 39°F. If the beer has not cleared after 24 hours, a second dose can be added. SilaFine should be stored cool, but do not freeze.

Unitanks & Brites:
If you are using a brite tank, SilaFine is best added to the beer stream inline when pumping from fermenter to brite. If you are using a Unitank and no brite tank, add to the top of the Unitank while rousing with CO2 for 5-10 minutes from the bottom. Or you can use a pump loop to recirculate the beer in a Unitank, instead of rousing with CO2. If added at ideal temperatures below 39°F, and well dispersed into the tank, clarification can take as little 8-12 hours. Otherwise clarification may take up to 48 hours. We advise against using more than the recommended amount, as overdosing can actually increase haze temporarily and cause a longer settling period. 

Dosage Rate in Whirlpool:
SilaFine can also be used in the whirlpool at a rate of 0.5-1ml per gallon to achieve a quicker and more compact sedimentation in the kettle.
Additional Notes:
SilaFine is based on a special selection of commercial grade amorphous silicon dioxide, also known as silica sol, at a concentration of 30%. Silica sol is known by a few names in brewing including colloidal silica, acidified silicates, silicon dioxide, and silicic acid. Unlike some other silica sols, SilaFine is not treated with aluminum oxide. SilaFine is a pure mineral and complies with Reinheitsgebot German beer purity law. Do not freeze. Store in a cool, dry place away from direct sunlight and heat.
The recommended shelf life is 12 months from the date the package is opened.

Need to fix a hazy beer I made.
James J on Feb 7, 2023
Can this be used in the keg that the beer will be served from, or does it need to be done before transfer to a keg?
Rodney Weaver on Jul 15, 2020
BEST ANSWER: This can be used inside the serving keg of the beer. If all that is settling out is a bit of haze from yeast and some light hops there should be no issues whatsoever. With heavy sediments you may get clogging in the small parts of the keg diptube or poppets. When clearing in the keg you will notice that the first pour of each day will spit out a little sediment then your beer will come out clear. More sediment will slowly work its way down to the diptube overnight until it has all been pushed out and the rest of your keg will be crystal clear.
I bottle condition my beer. If I use SilaFine will there be enough yeast left in the beer to carbonate?
David E. Durr on Jul 31, 2020
BEST ANSWER: I don't bottle condition, so I don't know from my own experience. I would expect yes, but with more time required to fully carbonate in the bottle. If you had a pressurized fermenter (e.g., Fermzilla), and the beer was carbonated at attenuation, you could use SliaFine to speed up the crash for clarity and then bottle directly from the pressurized fermenter.
Could you add fresh wort to the yeast cake from a batch of beer that has been cleared with Silafine or Biofine?

Biofine Clear Clarifier - 1 kg
BEST ANSWER: Yes that is possible. The trouble is you will be adding far too much yeast to the new batch at that point. The yeast in the vessel at the end of a fermentation can be used to pitch a batch 3-5x the size of the initial batch.
SilaFine accidentally got frozen. Will it be any good when thawed?
David Shields on Jun 5, 2023
BEST ANSWER: I'm afraid not, SilaFine hardens when stored cold; chances are once it thaw it will remain crystallized.
How does this compare to Biofine? I've never used either and am looking for a vegan alternative to gelatin.
Matthew Brazell on Jan 8, 2021
BEST ANSWER: I assume you mean Biofine CLEAR not Biofine. Biofine Clear is vegan, regular Biofine is not. Silifine is silicic acid and so is Biofine Clear. This product is vegan and compares to Biofine Clear. It’s important to understand the difference. This product Silifine works great, both as post fermentation clarifier as well as in the whirlpool for protein drop out. Highly recommend

Vegan Clarifier Works Fast
Just don't freeze it (like I did the first bottle, it does not go back into solution once crystallized). By far the best clarifying agent I have used.

So far not doing better than others
Bought this as a try for clearing my beers/musts/washes. So far I am on the second dose with no real results in a adjunct heavy wash. Did OK in a beer, but I used most all of the the vial between the two.

This stuff rocks.
Pretty effective! Best added inline but I found that I could get a good mix by either adding it to the keg, purging, and racking the beer on tap. If you have a conical fermenter, you can add it via your favorite oxygen-free method and rouse with CO2 to fully incorporate.

SilaFine? SilaMeh
Biofine it is not.

Was hoping this would be a more cost-effective alternative to Biofine but it just doesn't clear things up as quickly. In my experience SilaFine requires multiple doses to achieve the same clarity as a single doe of Biofine.

Your mileage may vary.

Great product
Recently discovered this clarifier and started trying it in my recent brews. Cleared up a lager over night and had NO affect on the flavor. A little pricier than using gelatin BUT saves you time as you dont have to go through the process of preparing the gelatin.

I use about 10ML in my keg with about .25g of sodium metabisulfate. This with a closed transfer to minimize oxygen and my IPAs are so happy. Crystal clear and they hold up over time.

I do use Brewtan now in my brewing, especially with the hoppy beers. Pressure fermentation, closed transfer into a keg with the Silafine and metabisulfate and a floating dip tube. This combo gives me a clean, clear crisp hoppy IPA that STILL taste fresh even after a month in the keg.

I do recommend this product.

It Works!
When I read the product info I wasn't sure. However, I love making the grain to glass process more streamlined. I've used it on two batches (an American Brown and American Pilsner) and both cleared quickly after using this product. There has been no negative impact on flavor or head retention.I would say the results are very similar to gelatin, without investing the time of making gelatin. I'll order more when I run out.
