    Hop Extract

    About BSG CO2 Hop Extracts
    CO2 Hop Extract is a pure resin produced through supercritical CO2 extraction, whereby the essential bittering and aromatic compounds of hops (alpha acids, beta acids, and oils) are separated from the leafy plant material. The extraction process removes solids, while the CO2 is recovered and reused. The final resin is then analyzed for brewing values and packaged in ready-to-use food grade cans.  

    Benefits of CO2 Hop Extracts

    •       Increased kettle and FV yields through reduced trub
    •       Reduced kettle foaming during the boil 
    •       Increased hop utilization from early boil additions
    •       Reduced shipping costs
    •       Variety-specific hop character when used in whirlpool
    •       Reduced polyphenol flavor contribution from plant material
    •       Improved shelf stability vs. pellet & whole cone hops
    •       Reduced storage space requirements

     

    About gma
    The unit of measure for BSG’s CO2 Hop Extracts is grams of alpha acid (gma) – a 150 gma can contains the resin extracted from 2-6 pounds of hops.  

    Brewing with CO2 Hop Extracts
    For ease of use, we recommend formulating recipes to use CO2 Hop Extract in entire can increments. 

    One method for adding extract to wort is to place an open or perforated can in the grant during runoff; another method is to dissolve the extract in hot water or wort in a separate vessel or container, and then add the mixture to the boil or whirlpool. Another common method is to suspend cans in the kettle during the boil using a basket. 

    CO2 Hop Extracts require wort boiling to isomerize their alpha acids. Early kettle additions (~ 60 minutes of boil time) will lead to an alpha acid utilization of approximately 35%. Actual utilization is dependent on equipment, process, and recipe specifics, and bitterness contribution should be confirmed through lab analysis of wort/beer.

    Late kettle or whirlpool additions of CO2 Hop Extracts will yield variety-specific flavor and aroma contribution. 

    Calculating Bitterness 

    The following formula can be used to calculate gma required to achieve a target IBU when using CO2 Hop Extract. IBU contribution is dependent on equipment, process, and recipe specifics, and should be confirmed through lab analysis of wort/beer.

    Please contact your sales manager for more info or assistance.                                     

    Required gma =        (target wort IBU) (hL wort volume @ end of boil)
                                                    (utilization % in decimal form) (10)
