Gelatin Fining

Directions for Gelatin Fining

Get some unflavored gelatin.  You can find it in the jell-o aisle and, perhaps, with nail care products.  All I’ve been able to find comes in little packages with about two teaspoons of gelatin in them – expensive packaging!  If you can find it in bulk, buy it that way.  Most homebrew shops have it.

Cool your beer as cold as possible.  Gelatin works cold so colder is better.

Dissolve 1 tsp unflavored gelatin in 1 cup water for five gallons of beer.  Any decent-tasting water will do.

Heat the water and gelatin to 150 degres Fahrenheit.  You can do this in the microwave or on the stovetop.  You need to get the solution to at least 150 degrees to dissolve the gelatin and sanitize the mixture, a bit warmer won’t hurt but keep it below 170 – you don’t want it gelling.  A good way to get to the proper temperature without overheating is to stir with your thermometer or digital thermometer probe.

When the mixture is warm and everything is dissolved, add it directly to the cold beer.  Swirl the fermentor or keg a bit to mix, let the beer stand cold for 24-48 hours.

Package as usual.  The beer will benefit from longer cold storage and if you’ve been fermenting at room temperature, bring the beer back to room temperature before packaging to keep your priming sugar calculations accurate.

Gelatin is an easy, inexpensive way to clear a hazy beer.  Using it will make your beers prettier.
