gelatin finings?

[TimpanogosSlim]

My friend the chemistry professor assures me that gelatin (and agar, etc) will bloom at any temperature above freezing - it's just much faster at 170f.

If you are lazy or just don't want to bother with reading the temp of the water you can mix it room temperature and let it sit overnight or whatever.

I did it in a small flask on my stir plate overnight once when i forgot that you cannot just dump gelatin grains in water - took a long time for the lump to dissolve. But it worked fine.

Today was my first time using gelatin to clear a beer. I have a pumpkin ale brewed about 3 weeks ago that is still very cloudy. As I was searching for a way to clear it I came across this thread. I used 1 tbs gelatin in 1 cup filtered water. Dissovled gelatin at 110 F for 12 minutes until clear. Heated to 170 F and held for 12 minutes. Cooled in a cold water bath for a few minutes then mixed into the pumpkin beer in primary. Hopefully this works. Thanks for all the great advice posted here!

Cheers!

Will gelatin clear cider as well?

I'd assume so, gelatin, I think, bonds with yeast cells or something and makes them fall out. But if it doesn't the gelatin doesn't impact flavor or anything so you could always try it and see what happens.

In about three days it should be pretty clear and good to go.

It's already very clear after 24 hours. I'm bottling this on Sunday to get the most from that gelatin.

...I took the recommended amount of gelatin (cant remember the amount but its on the package) and poured about 17 oz of water onto it. Then I heated it until it dissolved, then I added it to the keg, stirred with my plastic aerator/stir stick that fits on the end of my drill. I did this after crashing the keg for about 18 hours or so at about 35 or 40 degrees (guessing). This was done on Monday and after pouring small amounts every day to see the clarity of the beer, I can say that its still cloudy.
...

In order for gelatin to bind with the particulates, it needs to be thoroughly blended (become one with) with the beer. This can only be done if added to room temperature beer. Adding to a chilled keg, the gelatin simply jellied up and floated.

I use one heaping tablespoon for each five-gallon batch, mixed with 6 ounces of water. (heated to dissolved and then cooled slightly).

Depends what is making it cloudy.

If it's pectin, you should have used pectic enzyme 24hrs before fermentation. It doesn't work so well post fermentation.

If it only became cloudy after fermentation, probably. Or maybe it's not finished fermenting. Depends on the yeast really. my apfelwein started and ended clear. i used premier cuvee yeast.

I'm just in the pre-planning stages. Ran across a few recipes in the Cider forum I'm thinking about trying using Apple juice. So I presume that starting with bottled apple juice that is clear to begin with, the gelatin should clear it of yeast after fermentation. Pectic enzyme would be used for pressed or raw cider?

well, you may want to use pectic enzyme for any cider - but if you buy cloudy apple juice/cider, pectic enzyme should un-cloud it.

Hard to say, though. I've heard that the cloudy cider is due to set pectins, which would result from heat-pasteurized cider. but the one time i made cider out of unfiltered unpasteurized cider, that stuff went in dark and very cloudy, i added pectic enzyme and k-meta 24 hours before fermentation, and when fermentation was done it was as clear and bright as champagne.

Unfortunately i should have used more k-meta and waited longer. It turned into vinegar pretty fast after it was cider, even in the fridge. I hear that the cool kids are buying UV sterilized unfiltered these days.

There are some who suggest that a lot of pectin present at fermentation contributes to methanol production, and many who say that is nonsense.

it won't hurt, at any rate.

If your cider is finished (hydrometer readings over a few days remain stable) and it is still cloudy, gelatin will probably drop the yeast out of suspension. Depending on how anxious you are to drink it, time might do that for you too.

When you add it, do you just gently dump it in - or try to give it a stir?

I slowly poured the gelatin water mixture into the fermentor. And gently rocked the fermentor to mix it up. I'm brewing with 6 gallon carboys so rocking the carboy works well for mixing.

Cheers!

Hello, I just added Gelatin to my pumpkin beer last night and due to time constraints I will have to bottle this evening. Do you think bottling this soon after adding the gelatin will make adding the gelatin for clarifying puposes pointless? Thanks

 

[mirogster]

2 or few more days would really make big difference. But if you cant't wait Most probably it will clear in the bottles, and you'll finish with jelly sediment. And yeah, bottle carb will take a little bit longer, than usual

I tried adding a heated (per BM's instructions) gelatin/water mixture directly to the keg and then racking an IPA on top of it, hit the keg with co2 and then let it sit for a few days at room temp.

Not only did it not clear the beer, but it stripped all the hop aroma from the beer. Only thing I can guess is that A) the beer should have been cold B) the gelatin mix cooled down too much as the beer was racking. If it's normal for gelatin to strip off hop aroma, I doubt I'll use it again as I lean towards hoppy beers.

Gelatin does not affect aroma. It is not an "aroma scrubber". It is totally flavor and aroma neutral and has no capacity to neutralize aroma.

No doubt your beer became substantially less aromatic when chilled, compared to room temperature. (Ice cold beer never has the same flavor or aroma profile as a beer served at temps appropriate for the style.)

With a proper pour and if allowed to sit for a few minutes (to warm slightly), the aroma should come back.

 

[Matteo57]

Is there any reason I couldn't throw the bit of water and disolved geletin into the primary, stir that up a tad and let sit a few days and then rack off there? I normally don't do a secondary unless it's a big beer I want to age!

Thanks!

BM, I wouldn't have thought gelatin would effect aroma, however this IPA had that awesome massive hop aroma as I racked it to the keg, and absolutely nothing now. Gelatin is the only change to the process I've made.

I keep my kegerator at 40F and let half a pint sit to room temp last night. It still had zero hop aroma, and actually smelled malty. At this point I'll probably pop the keg and toss a few more oz of hops in to re-dry hop it.

Seriously, Knox gelatin is the way to go.

Add it to a keg along with priming sugar and sit back and wait. Crystal clear and carbonated to my liking everytime.

 

[msa8967]

I read through the first dozen pages of this thread but could not find an answer to my particular question regarding adding gelatin to kegged beer. I have 6 kegs that I naturally carbonated with corn sugar several months ago. I placed the kegs in my attached garage that stays around 40F. I am wanting to know if adding gelatin to the kegs after they have been chilled for 24 hours will do any thing at this point in the process to clear the beer. Any thoughts?

 

[bcryan]

You want the beer to be cold when you add the gelatin. Chill haze will form when it's cold. Adding the gelatin with remove the haze and drop the yeast. You should have crystal clear beer in a few days.

 

[msa8967]

Not sure where in the thread it suggested adding gelatin to chilled beer...but doing so will result in instantaneous coagulation of the gelatine. It needs to be mixed into room temperature beer, prior to chilling.

Think about it...liquid gelatin turns to..."jello" in the fridge.

Seems like I may have made a big error in reading the previous entries and I added the mixed gelatin/water solution to my already cold beer that has been chilled, carbonated and kegged. How big of a screw up will this be? I don't think I can safely remove the dip tubes to bend them slightly upward.

@msa8967
That is how I normally do it and it turns out fine. Let it sit for 5 days or so and then test it. Your first pint my be a little cloudy but it should be clear from then on.

Thanks for letting me know that this method will be OK. Not too sure that I would be a fan of jello flavored beer pieces.

I've only used gelatin in already chilled kegs and it's worked every time.

I'm about a dry-hop a beer with 3oz+ of leaf hops. I suspect that this will prevent the gelatin that I pour into the carboy 3 days before bottling from getting through. Does anyone have any experience with this? I'd much prefer not to secondary just to add in the finings.

I wouldn't leave gelatin in the fermenter for 3 days before boiling the wort!!! Probably wont work too well.

Add the gelatin before the hops; same day is OK.

Sorry, I meant "bottling," not "boiling." You don't foresee a problem adding the gelatin at the same time as adding the dry hops? Can one therefore add gelatin any time after fermentation, regardless of the dry-hopping schedule?

Thanks

I keep seeing posts quoted in this thread where some are saying that you MUST add the gelatin at room temperature. This is not true. Adding at room temperature may work but you don't have to warm up the beer to add gelatin.

In fact, in the book New Lager Brewing, Greg Noonan says it is best to add gelatin at a temperature UNDER 50 degrees and that closer to freezing is even better.

I have always done it this way and the beer clears up incredibly well. The Gelatin does NOT turn to Jello as some here have been warning. Perhaps people have had issues because they added the gelatin at cooler temperatures but didn't follow the other instructions. Here is what Greg Noonan says:

For a 5 gallon batch of beer, add 5 grams of gelatin to 10 ounces of water, cover it, and let it sit for an hour (to bloom). Then, gently heat it up and stir to dissolve the gelatin. Heat to 150 - 160. Do not go over 160 degrees. Then, do not let the gelatin cool to under 120 degrees before adding it to your beer. In other words, the gelatin solution should be between 120 and 160 degrees when you add it to your beer and mix it in. Mix it into the beer gently for 2 to 3 minutes.

I stir mine into the carboy with a sanitized racking cane. You can also gently rock the carboy. I keep saying gently because you don't want to add oxygen to your beer.

Like I said, this works extremely well. I've done it with a cloudy Kolsch yeast and it cleared it right up. No floating Jello. Just beautiful, clear beer.

I used to do this, it works great. I believe it is preferable to add gelatin to already cooled beer. You will lose some CO2 because you have to blow off the pressue to open the corny and dump in the gelatin.
