No need to buy anything more expensive. Knox works great.
You don’t have to be kegging, either. You can add it to the fermenter before bottling or kegging and wait a day for it to clear, plus there’s another thread here (search gelatin) where somebody was adding it to the bottling bucket.
When adding to the keg or fermenter it helps if the beer is much colder than the gelatin. This way is starts on top and slowly sinks to the bottom taking all the haze with it.
• Fill liquid measuring cup with 1 cup water
• Microwave on high until very hot, but NOT boiling (around 150-160 F)
• Add 1 tsp gelatin to hot water and mix thoroughly until completely dissolved (it will take about 10 minutes)
• Add gelatin/water solution directly to keg
• Put keg top back on, purge O2, and shake to mix in gelatin solution
• Wait 3-4 days
• Pour clear beer
edit: make sure your beer is cold before adding the gelatin
Is it bad to start force carbonating before letting it settle 24 hours? I add it to the keg, rack on top of it, seal and pressurize the lid, shake a bit, then hook it up to start carbonating.
From my experience… I’ve had alot of success with using gelatin immediatey upon kegging and force carbonating. I should add that my beer has already been cold crashed in the primary so it is chilled going into the keg.
Nah… I usually rack into the keg and put it on pressure to start carbing, but don’t add the gelatin until a day later once the beer is cold. Then I just continue carbing until it’s done, blow out all the crud with the first pint or two, and have nice, clear beer.
However I may add that if the beer has been cold crashed it can be fined immediately after racking into the keg and force carbonated. This is my current SOP.
