Durchstossen

Durchstossen is a traditional Bavarian beer brewing technique that involves the addition of a small amount of beer to a wort (unfermented beer) during the brewing process. This technique is primarily used to enhance the flavor and aroma of the final beer. The added beer is typically a dark, malty beer, such as a doppelbock or a dark lager, which contributes a rich, complex flavor profile to the wort.

The process of durchstossen involves heating the wort to a specific temperature, usually between 68-72 degrees Fahrenheit (20-22 degrees Celsius), and then adding the beer. The mixture is held at this temperature for a short period, typically 15-30 minutes, to allow the flavors to meld together. After the durchstossen process, the wort is cooled and fermented to produce the final beer.

The durchstossen technique is often used in the brewing of traditional Bavarian beers, such as doppelbocks and weissbiers. It is believed to contribute to the unique flavor and aroma of these beers, which are characterized by their rich, malty taste and complex aroma profile. The durchstossen process is also used in the brewing of some modern craft beers, where it is employed to add depth and complexity to the flavor profile.

In summary, durchstossen is a traditional Bavarian beer brewing technique that involves the addition of a small amount of beer to a wort during the brewing process. This technique is used to enhance the flavor and aroma of the final beer, and is often employed in the brewing of traditional Bavarian beers and some modern craft beers.
