gelatin finings?

[serum67]

Adding gelatin to my kegs has changed my life.

Do you still get those off flavors?

 

[Daparish]

Will gelatin get rid of chill haze?

 

[cylered16]

Daparish: Yes. Adding the gelatin in a secondary will crash out proteins that are responsible for forming chill haze.

Only if the beer is cold enough to form the proteins that are responsible for causing chill haze

How does this work? Aren't the proteins already present in the beer before it's cooled?

 

[Rhoobarb]

[FONT=Verdana, Arial, Helvetica, sans-serif] Lack of cold break causes chill haze. When a beer is chilled, the proteins partially precipitate and form a haze. As the beer warms up, the proteins re-dissolve.

I use gelatin quite often. The proteins are attracted to it and attach t the gel. As it (the gel) falls, it drags the proteins with it. Good, long chilling helps, too.

Polyphenols and proteins form to make a larger particles in cold beer and I know you have heard the saying “The bigger they are the harder they fall”

 

[Daparish]

Hmmm, I currently have no way of cold crashing any of my beer after I add gelatin. If I can't get good cold break after brewing, am I just stuck with chill haze, gelatin or not?

To cut back on the chill haze without any crash cooling available use Irish Moss. I use SuperMoss from LDCarlson. I use only a heaping teaspoon of this in 4oz of pre-cooled wort and add with about 10 minutes left in the boil and I have some really great results with it. However, the first time I used it I got really careless and used about 2 tablespoons of it. Yeah, the beer was clear, but a lot of the important non-fermentables were gone too, which left me with a really flat-flavored beer.

Not sure about this but +1 on Irish Moss...it helps form the cold break

 

[neuron555]

The Irish Moss won't change the flavor. It, and other fining agents, act by attracting the charged particles and dropping them out. The nonfermentables are sugars that the yeast can't eat, but they are in solution, so will stay put. It can cause yeast to drop out, but this is only a problem with a hefe where you want the yeast. Even if bottle conditioning, there will be enough to carbonate - may take a little longer, but longer conditioning makes it better anyway.

If I have my beer already cold crashed is it too late to add gelatin?

Nope....works better cold

 

[crlova2]

So the dissolved gelatin in the warm water won't turn right into jello when I add it to the already cold beer in the secondary ~35F?

 

[neuron555]

It gets too diluted to make a lump of beer jello.

My grocery store was out of Knox but there was a store brand unflavored gelatin (kroger) I am assuming it will work the same?

AFAIK, gelatin is gelatin...Kroger brand should be fine.

My current all grain strong Belgian is cloudy as miso soup. I am planning on adding gelatin. I am summarizing what I have been reading, and please correct me if I am wrong (or give me a thumbs up if I am right!) so I can do this correctly. I am adding it to my secondary, the beer is already racked in there.

-Any unflavored gelatin should do, just Knox is the cheapest.
-1 tablespoon per 5 gallons, put in 2 cups of water, bring to 170F for 10 minutes and then cooled down to 95F to be pitched.
-Stir it up so the gelatin mixes good.
-I can add it to my secondary (which is already racked) 2 days before bottling and it should be clear by then.
-There should still be plenty of yeast to allow for carbonation, just add the normal amount of priming sugar when bottling.

Am I corerct in the thought that once the fermentation is complete my risk of contamination goes down? Need to be certain I can open that lid up to stir in the gelatin a week after the fermentation has completed, adding some oxygen and such without messing up my brew.

Thanks!

 

[neuron555]

Gentle stirring without splashing around won't introduce any significant oxygen to be noticeable. If you want to boil the water first then let it cool to 170 to be safe, you can, but by the time the fermentation is done, there's enough alcohol in there to finish off a few bugs. You should be all set.

 

[Wayoff]

Great thread.. I read the whole thing.. It should be Stickied .. pretty much covers anything about the use of Gelatin

 

[RM-MN]

-I can add it to my secondary (which is already racked) 2 days before bottling and it should be clear by then.

This may not work out for you. I've seen it take 4 or more days to settle out all the cloudiness.

It doesn't have to be that cold for the proteins to precipitate out in the presence of gelatin. You can (and I do) get beautifully clear beers after adding gelatin for a few days at fermentation temps. No chill haze.

Here's another gelatin/crash cool question I couldn't find an answer to.

I just added gelatin finings and am crash cooling a friends Raspberry Blonde Ale recipe.

Anyway, when it comes time to bottle, do I have to let the beer warm back up to room temperature before adding the priming sugar & bottling? Or can I just rack it to the bottling bucket/sugar while its still cold and immediately bottle?

Thanks all!

you can bottle cold. let it condition at room temp.

I'm going to tr this for my pumpkin ale I have in the secondary. I racked from the primary after two weeks and found a 4 inch layer of trub, but it wasn't really compacted since there was pumpkin stuff in there. When I racked to the secondary it sucked up some of the trub/pumpkin stuff and probbaly some yeast. I'll post pictures of the before and after when I get a chance/remember.

Update: So I've added the recommended 1 tablespoon to 2 cups of water and dissolved the gelatin at ~180 degrees for about 10 minutes. I let the mixture cool to about 150F, and poured it down the side of the carboy to avoid aeration. I gave it a quick swirl and here's the starting picture....

I just turned on my crash fridge and will place it in there tomorrow. I'll follow up with additional photos for those interested.

I have a question about dry-hopping and gelatin.
I have two kegs force carbing @ 12psi - 39F. Each keg has 2oz of pellet hops in a fine nylon mesh bag hanging from dental floss. I want to add the gelatin to clear this beer for Christmas, but do not want to remove the dry-hops because the aroma is not there yet.

Can I add the bloomed gelatin to these kegs while dry hopping?
My concern is the gelatin will form some sort of skin over my mesh bag (its a pretty big bag 6"x12").

Thanks so much.

 

[serum67]

As per several conversations with Mike McDole (Tasty) from the BN. These are his words exactly:

"I dry hop in the secondary warm. Rack to kegs after 5-7 days. Chill to 33-40F and add the gelatin in the keg. The gelatin works best if the beer is cold. You can also chill the secondary and add the gelatin there. That's more akin to what the pros do."

This has worked great for me. Beers like Mike's Janet's Brown w/ Russian River used gelatin in a production environment.

Sorry for the lack of updates. After chilling in the fridge for about a week there was noticeable clearing in the secondary. However, the beer wasn't perfectly clear and had some haze to it. My guess is that it was starch haze from boiling with the pumpkin instead of mashing. I was still doing extract batches at that point so I didn't have the option. I will say that the gelatin does do wonders for clearing hazy beers in general. I'll be using for clearing from now on since its minimal effort and doesn't add much cost to a batch. I'm hoping that doing all grain and full boils will enhance the effects.
