In this brief guide, we will answer the question “what is the best way to sanitize beer bottles?” with an in-depth analysis of what is the best way to sanitize beer bottles. Moreover, we will also discuss different methods of sanitizing beer bottles.

What is the best way to sanitize beer bottles?

The best way to sanitize beer bottles thoroughly is by soaking them in a cleaning solution and then sanitizing them. You may use bleach or a commercial cleaner to pre-clean the bottles. Let them soak in the solution for at least 10 minutes. Then sanitize your bottles in the dishwasher, or use a bleach solution.

How can you clean and sanitize beer bottles?


The first time a bottle is used it should be soaked in a cleaning solution (like bleach water), and scrubbed inside and out with a nylon bottle brush. A heavy-duty cleaning is needed to ensure that there are no deposits in which bacteria or mold spores can hide. 

This helps the sanitizing solution reach all areas; you can be assured of sanitized bottles. If you are diligent in rinsing your bottles promptly and thoroughly after each use with your homebrew, only the sanitizing treatment will be necessary before each use in the future.


After the bottles have been cleaned with a brush, soak them in a sanitizing solution or use the dishwasher with the heat cycle on to sanitize them. If you use a heavy-duty bleach solution to sanitize, allow the bottles to drain upside down on a rack, or rinse them with boiled water. 

Do not rinse them out with tap water unless it has been boiled first. Rinsing with unboiled tap water is the number one cause of spoiled batches.

 Also sanitize the priming container, siphon unit, stirring spoon, and bottle caps. But don’t boil or bake the bottle caps, as this may ruin the gaskets.

Can you sanitize beer bottles in the oven?

Bake at 350° F for 90 minutes. Allow bottles to cool naturally, such as overnight. If you will not be filling the bottles immediately, place them back in their cardboard cases. As long as the aluminum foil remains intact, the bottles will remain sterile indefinitely ready to use whenever you are ready to bottle.

How can you sanitize beer bottles using a dishwasher or bottle washer?

Dishwasher sanitizing:

  1. Use a dishwasher for cleaning the outside of the bottles only. Don’t rely on it as the primary cleaning method for the inside.
  2. Use the dishwasher only after cleaning the bottles. The dishwasher should only be used for sanitation, not sterilization. Especially for narrow neck bottles. Using a dishwasher alone will not clean small mouth-opening bottles.
  3. Turn on the temperature to use hot water as it is better in killing germs and bacteria.
  4. Put your bottles in the rack spikes.
  5. Use the dishwasher to rinse the cycle without soap.
  6. Be careful with very hot water and steam as this will warp some plastic tops.
  7. Some dishwashers have sanitizing heat cycles. Which makes them great as heat also kills any pathogens remaining in the bottles. If you don’t have this, a regular rinsing at a high temperature will do.
  8. Do use soap or detergent. Set your timer and leave it for around ten minutes.
  9. Once done, let the bottles drip dry. Place them upside down on a drying rack.
  10. Do not use a towel to dry the bottles. It might get contaminated. Just let it drip dry on the rack. 
  11. When the bottles are dry, you can place them in spaces or containers that are not exposed to dirt or dust. 

Sanitizing with a commercial solution:

  1. Rinse the tub you used to clean the bottles.
  2. Add hot water to the tub.
  3. Use one tablespoon of bleach per gallon of water.
  4. Soak the bottles for 20 minutes.
  5. After soaking, rinse the bottles using boiled water. Some use tap water to thoroughly clean. But just to be on the safe side to kill bacteria and germs, use boiling water.
  6. Dry the bottles once sanitized
  7. Once the bottles are dry, keep them in a place or container where there is no dirt or dust.

What is the bleach-to-water ratio for sanitizing and disinfecting?

1 tablespoon of bleach per 1 gallon of water will give you a 50-200 ppm sanitizing solution. This can be used to sanitize dishes, utensils, food preparation counters, and tables. This will give you a 500-800 ppm disinfecting solution.

Can you sanitize beer bottles by boiling them?

Dropping cool bottles in boiling water may break them or make micro-fractures that will fail under carbonation pressure. Always do temperature changes slowly, submerge bottles, and then apply heat once at 180°-200°F remove from heat. Boiling can make too much movement and bang bottles around.
