In this blog post, we will guide you through the process of brewing your own Blood Orange Rattler, using a helles lager as the base and adding a splash of blood orange soda for a burst of fruity flavor. Let’s get started.

Brewing Process:

1. Heat approximately 5.25 gallons of distilled water to 155 degrees Fahrenheit.
2. Add salts to adjust the water profile according to your preference.
3. Add the grains (German Pilsner Malt, German Wheat Malt, and Vienna Malt) to the water.
4. Mash the grains at 150 degrees Fahrenheit for 30 minutes.
5. After the mash, remove the grains and bring the mixture to a boil.
6. Boil the wort for 15 minutes, adding Warrior hops for bitterness.
7. Chill the wort to around 70 degrees Fahrenheit using a wort chiller.
8. Transfer the cooled wort to a sanitized keg, leaving about a gallon of headspace for fermentation.
9. Pitch the yeast into the keg and close it up.
10. Ferment under pressure by attaching a spunding valve to control the pressure (10-12 psi is recommended).
11. Allow the beer to ferment under pressure for one week.
12. Check the progress by pulling a sample using a picnic tap attached to a beverage connect.
13. Once fermentation is complete (final gravity around 1.010), transfer the beer to a new keg, leaving some headspace.
14. Stabilize the beer in the new keg by adding potassium sorbate and a Camden tablet.
15. After one day, add blood orange soda (or your preferred citrus soda or juice) to the keg, aiming for a 50/50 mix of beer and soda.
16. Close the keg and carbonate it by adding pressure.
17. After a few days, your Blood Orange Rattler is ready to be enjoyed!


Brewing your own Blood Orange Rattler is a fun and rewarding experience. This light and citrusy beverage is perfect for warm days and makes a great gift for your loved ones.

Whether you choose to brew the helles lager separately and mix it with the soda on demand or pre-mix it in a keg, the result is a delicious and refreshing drink that is sure to impress.

So grab your ingredients and get brewing! Cheers and happy brewing!
