For the traditional Czech lager, it will use a Triple decoction mashing. What is the decoction mashing? How many types Decoction mashing methods are usually used in a micro brewery? Decoction mashing is a traditional mashing technique used in some beer styles, including certain lagers like Märzen and Bock. This method involves removing a portion of the mash, boiling it, and then returning it to the main mash to raise the temperature and achieve different steps in the mashing process. Decoction mashing can add complexity and depth to the beer's flavor profile. There are three primary types of decoction mashing methods:

Single Decoction:

In a single decoction, a portion of the thickest part of the mash (the mash with the highest concentration of sugars) is removed and heated to a boil.
After boiling for a short period, the decoction is returned to the main mash, raising the overall temperature of the mash to achieve the next rest temperature.
Single decoction mashing is a simplified version of the decoction process and is often used for less complex beer styles.

Double Decoction:

In a double decoction, two separate decoctions are taken from the main mash.
The first decoction is usually a thicker portion of the mash, and it is boiled to achieve the protein rest temperature. After boiling, it's returned to the main mash to raise its temperature.
The second decoction is taken from the main mash after the first rest (e.g., saccharification rest) and is boiled to achieve the next rest temperature. Again, it's returned to the main mash.
Double decoction mashing provides more control over the mash profile and can help develop complex malt flavors.

Triple Decoction:

The triple decoction is the most complex and time-consuming method.
It involves three separate decoctions, each boiled and returned to the main mash to achieve specific rest temperatures.
This method was historically used for beers that required a well-defined malt profile and rich flavors.
The triple decoction process can lead to intensified malt flavors and improved overall beer quality.
Each type of decoction mashing introduces a boiling step, which can lead to Maillard reactions and caramelization of sugars, contributing to the beer's color and flavor complexity. Decoction mashing is labor-intensive and time-consuming compared to modern single-step infusion mashing, but it can result in unique and authentic flavors that are appreciated in certain traditional beer styles. It's important to note that many modern breweries use alternative methods to achieve similar results, such as using specialty malts and controlled fermentation conditions. We can customize the brewery equipment according to the request.
