Isomerised Kettle Extract (IKE) 

In IKE, the α-acids have now been isomerised to IAA, the soluble isomer which makes beer bitter. 

The product is similar in appearance to the original CO2 extract but is slightly more mobile, and still contains the hop oils, waxes and beta-acids present in the original material. This product is well rounded and easy to use in place of whole hops, pellets or CO2 extract.

When we produce IKE we achieve a alpha-acid to ISO-alpha-acid conversion of 97%.

We can manufacture either generic IKE, or varietal specific batches of IKE to preserve the character of the original hop extract. 

At JRM, our process is monitored and quantified using highly accurate and reliable HPLC technology. By investing in our laboratory capabilities, we ensure that we manage and dispense the correct dose, each and every time. 

IKE is typically packaged in our range of tins, 1/2, 1, 2 & 4 kg fills. Bulk containers such as steel drums and IBC’s are also available. Resin-based also have a longer shelf-life, contact us here to find out more & request a PDS / SDS.

  • The product is easy to use in place of whole hops, pellets, or CO2 extract. It is available in various packaging options, from small tins to bulk containers, making it suitable for different brewing scales and simplifying the brewing process.

  • IKE can be manufactured as either a generic or varietal-specific product, preserving the original hop character. The production process is closely monitored using HPLC technology, ensuring accuracy and high-quality standards in every batch.

  • IKE contains isomerized α-acids (IAA), which are highly soluble, providing a consistent bitterness in beer. This solubility ensures a more predictable and uniform flavor profile compared to using whole hops or pellets.
