This article will tell you how to make sour beer, its different types, and a step-by-step guide on brewing sour beer.

What is Sour Beer?

Before we proceed to the brewing process, let us first introduce what sour beer is!

Based on the way it is called sour beer is one of the types of beer that has a bad taste and acquires sour flavors. It is called sour beer because of the unique process of brewing using yeast and wild bacteria, making the beer taste sour.

In addition, other beers also have yeast in them to produce beer flavors that are familiar to their taste.

History of Sour Beer

History of Sour Beer

Sour beer started around 4,000 B.C. During this time, the beers had natural bacteria, such as lactobacillus or sour milk, present in the beer. But since the technologies evolved in the mid-nineteenth century, sour beer disappeared virtually, and ales became popular.

In 1970, sour beer became popular again among drinkers all over the globe. The first sour beer was brewed in the 18th century in Belgium and still operating for hundreds of years.

German and Belgian people are one of those people who introduced sour Beer to American people during the 1970s.

Brewing Sour Beer

Because of the challenges and struggles of brewing sour beers, not all beer breweries are willing to add Sour Beer to their beer menu. Sour beers have various flavors and intensities. The yeast and bacteria do not usually go with brewing beers making the sour beer unique.

We will show you how to brew sour beers from Kettles or Metal. Before starting the brewing process, you must know the specific type of sour beer you want.

How to Brew Sour Beer in Kettle?

Beer breweries mostly prefer brewing their beers in Kettle Sour since Kettles have a lot of control when it comes to bacteria processing. This type of equipment usually is the safer way of brewing sour beers as long as you meet the proper hygiene testing and practices at your place.


  • Storage Bottles
  • Primary and Secondary bubbler (plastic fermenter)
  • Timer
  • Kettle
  • Long-handle stainless spoon or plastic
  • Thermometer

Step 1: Mashing the grains

Step 1 Mashing the grains

Get your grain, mash it in the barley with the wheat, and run your wort off into the kettle.


Step 2: Bring the temperature up

Bring the temperature up

Instead of adding the wort into your hops and boiling it, it is best if you raise the temperature of your kettle so that the wort will be sterilized.

(Note: Grains have different bacteria on them, and you can use the grain as a sour beer source.)


Step 3: Let it Cool

Let it Cool

After doing step 2, let it cool for at least 40 degrees in the kettle by circulating it again. The challenging process of this brewing process is the oxygen pick-up, which can be a significant factor.


Step 4: Seal your wort with CO2

Seal your wort with CO2

Oxygen can cause the beer to go stale and make the yeast produce unwanted aromas and flavors. So if you are brewing sour beers with lactobacillus combined with oxygen, your sour beer can be considered tinny or vinegary.

To avoid being that sour, it is best to cover your wort with a blanket that has CO2.


Step 5: Add Bacteria

You can now add bacteria with a temperature of 40 Degrees. You can use different bacteria that go well with creating sour beer, but most brewers use the lactobacillus Plantarum bacteria.

This bacteria is active in foods such as yogurt, cheese, sourdough bread, and sauerkraunt.


Step 6: The Souring Process

The Souring Process

In this stage, it is preferable to achieve a P.H. Level of low to middle to low 4 to allow your bacteria to gain a good hold of your wort.

Let your bacteria ferment between 24 to 48 hours and during this process, aim for your P.H. level to go down for at least 3.5 to give your beer a sour base without making it very sour.


Step 7: Boil it Again

Boil the wort again to kill bacteria and stop the souring process. You can add it to the hops and transfer your wort into a fermenter. The bacteria did not have a chance to get much sugar, so the yeast had a lot to consume and ferment.


Step 8: Add the ingredients

Add the ingredients

You can now add your different ingredients to the beer. You can add cucumber and mint as the base or other fruit and spice!
