BrauKon HopBack Pellet
Wort aromatization between the whirlpool and wort cooling
Whirlpool hopping can be used to create an even more intense “hot hops aroma” in addition to the hops dosing processes during wort boiling. Here, the bitterness is complemented by aromatic nuances and is perceived as more harmonious by the palate. To achieve this, BrauKon HopBack Pellet is integrated parallel to the whirlpool.
Flexible and effective
Due to the increased volume of hops pellets, classic whirlpool hopping is associated with considerable wort losses when removing spent hops. At the same time, the applicable quantity of hops is limited as otherwise the whirlpool’s separation of spent hops would only partly function. The BrauKon HopBack Pellet can reduce wort losses clearly when dosing large quantities in the whirlpool.
Variable, defined aroma profile
BrauKon HopBack Pellet allows for a defined control of the aroma profile through the extraction outside the whirlpool. Thus, the acquisition of essential oils can mostly be separated from the isomerization and leaching of the hops leaf fibers. The rate of isomerization, the increase of bitterness, can easily be controlled through the heat holding time. To emphasize delicate flavors of hops, BrauKon HopBack Pellet can selectively extract essential hop oils with shorter flow times.
Through the extraction after the Whirlpool, the washed-out Alpha acids are immediately cooled in the wort cooler, so that less iso-alpha acids are formed. Especially with larger quantities, the ratio of aroma and bitterness can be influenced in favor of a more harmonious balance. With this process, the release of undesirable bitter compounds from the hops solids can also be signifi cantly reduced with a shorter extraction time. This closed process prevents the evaporation of hop aroma compounds. This creates delicate aromas without scratchy bitterness. BrauKon HopBack Pellet
is also suitable for orange peels, coriander or other alternative fine-grained aroma sources.

Filling
BrauKon HopBack Pellet is filled with hops pellets or other flavoring sources through a large access-port.
Aroma extraction
In the HopBack Pellet, a special system which controls the flow of the hot wort ensures the quick dissolution and efficient extraction
of aromas. An integrated special sieve holds solids back from the wort.
Removal and cleaning
The leached spent hops are removed with water following aroma
extraction. Optionally, removal can be performed with a floor slide.
Then hop cones can be used, too. The BrauKon HopBack Pellet is suitable for inline CIP cleaning with the brewhouse.
