How do you use gelatin finings?
 
I currently have 15 gallons :rockin: of a light ale that was all brewed together as one batch. I split the fifteen gallons into three 5 gallon batches in order to experiment with some different yeasts as well as some different primary vs secondary times and clarification techniques so I could compare the results. I want to add gelatin finings to one of the 5 gallon batches so I can compare to the other ten gallons which will not have had the gelatin finings added.

My beer was in the primary for 7 days and I just transferred it to a secondary (plastic bucket) about 4 days ago. My plan is 7 days in the primary and 14 in the secondary and then bottle.

At what point do I add the gelatin finings? Also, what process do I use to prepare and add the finings. How much gelatin & water do I need to prepare?

Gelatin works when the beer is already COLD, best done in bulk (carboy/keg)

1/4 cup per packet of gelatin, stir into 120 degree water let sit 10 minutes or so and dump into COLD beer.
Give it a little shake/swirl and wait 3-5 days for clear beer

I usually only use gelatin when I crash cool (for kegging). I use half a packet for 5 gallons. Dump the gelatin cyrstals in 2 cups of warm water for about 15 minutes (so it can "bloom"). Then heat mixture to almost boiling, then cool. Dump the concoction into my carboy of beer that's been chillin in the fridge.). Wait about 3 days and keg....easy as that. I've used gelatin when bottling (and crash cooling too), and it works...just takes longer to carb.

How much extra time is required to carbonate bottles after you have been fined your beer with gelatin?

Hammy71 08-09-2009 01:18 PM

It's varied.... but I'd say at least a couple more weeks.

Hammy's got it right. Warm water to dissolve then heat it up and cool.

But it should be pointed out...do not let the gelatin come to a boil
If it does, it breaks down the structure and will not work.

I think this is so true. I've been using gelatin for beers being served at parties and BBQs etc... The only time the gelatin trick failed on me was when I let it boil.....I wrote to knox and was told pretty much the same as ghack pointed out. Don't boil it.

So how much is 1/2 packet or 1/4 packet? I forgot the whirlfloc for a recent batch and I picked up an oz of gelatin at my LHBS for a buck because I didn't wanna bother with an extra stop.

The batch is ready to bottle and is sitting at 34F in my ferm fridge right now.

I've currently got two kegs with gelatin in them (added on 8/23) and I'm going out of town until 9/8. Does anyone know if there could be any problems if I keep letting them cold condition until then (it'd probably be almost 20 days by the time I am ready to rack them to serving kegs). I'd just guess that another week or two would be a good thing, but who knows?

The only problem with letting them cold condition that long is your beer will be even more clear.
