How to Use Gelatin to Clarify Your Beer

Directions

  1. 1Add 3/4 cup of water to your measuring cup.
  2. 2Heat the water slightly before adding the gelatin to help it dissolve quicker.
  3. 3Add 1 tsp of gelatin and stir with a thermometer to get a reading.
  4. 4Heat the solution to 150-155F using short 5-10 second bursts in the microwave, avoiding boiling.
  5. 5Once the target temperature is hit, take the lid off of your keg (or fermenter) and pour the solution directly into your beer.
  6. 6If adding gelatin into a keg, reconnect your CO2 line and purge the headspace.
  7. 7If adding gelatin into a fermenter, replace the airlock.
  8. 8Wait 24-48 hours while the gelatin works to clarify the beer.

Tips

  • Ensure your beer is cold, at serving temperature (34-38F), before adding gelatin.
  • If adding to a keg, the first pint or two might be cloudy due to sediment at the bottom where the dip tube draws from.
  • Boiling the water first and then letting it cool to 150-155F before adding gelatin can help with sanitization.
  • Allow the gelatin to 'bloom' in water for about 5 minutes before heating.
