Will be adding the 1 ouncer to my MoreBeer order to try it in a couple of batches. The quart size will do 64 five gallon batches. $17 for 64 batches is pretty reasonable, not to mention you can just put a TBSP full in a keg and rack onto it. Much less hassle than gelatin.
I'm assuming this would have to be onto cold-crashed beer, right?
From MoreBeer:
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.
So if one doesn't cold crash (I don't), one could either a) add it to the warm beer while racking into a keg and then chill, or b) rack beer into keg, chill, open the keg and then add it.
I guess.
I was thinking the same thing. I do not crash until the beer is in the keg. Adding it to room-temp (ish) beer would probably have
some benefit but I know that a gel solution REALLY does a nice job when it's added to cold beer. I will chill the keg, add the gel solution and walk away. No agitation, no second application, etc. Yes, you have to prepare the gel but I'm used to that. Still, if someone tries this and has a rave review, I will listen. It's clear beer after all.
