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 up to 80% 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.

To achieve a different aroma profile, the BrauKon HopBack Pellet can be integrated either at
the bypass to the whirlpool or at the bypass to the wort cooler. Isomerization of the washed-out
alpha acids can occur due to recirculation in the whirlpool, increasing overall bitterness. To emphasize the delicate flavors of hops, the washed-out alpha acids are immediately cooled down
in the wort cooler, resulting in a minimum of iso-alpha-acids being formed. 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.

  • Procedure

    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. Flavor or bitterness can be emphasized depending on how
    the wort is controlled with the dissolved aroma compounds.

    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.
