Iso-Extract 30%

Description

Iso-Extract 30%

is an aqueous solution of the potassium salts of iso-alpha acids. ISO 30% can be used post fermentation to top-up bitterness or to partially replace traditional forms of bittering. ISO 30% is typically added before filtration for best yield results.

Advantages

  • Bitterness
  • Foam
  • Anti-microbial

Usage & Methods

  • Dose anytime during kettle boil as a partial replacement for kettle hopping
  • Post fermentation for touching up IBU’s
    • Post fermentation utilization 85% – 90%
    • Good – add product to empty vessel and push with nitrogen (NOT CO2) into beer line when starting to fill tank
    • Better – add product to empty beer keg and fill with pH 8-9 adjusted de-aerated, de-ionized water and push with nitrogen (NOT CO2) into beer line when starting to fill tank
    • Best – meter the concentrated product into transfer stream using a diaphragm pump. Attempt to delivery evenly throughout 80% of the transfer of beer. Dispense solution into the beer transfer stream pre filtration
  • Inject on suction side of beer transfer pump
  • Link to methods for bench-top testing in bottles or kegs.

Notes & Suggestions

  • Limit use of product to 30% – 40% of total bitterness to avoid a noticeable change in the bitter quality
  • Post fermentation for best utilization and efficiency (85%-90%)
  • Inject on suction side of beer transfer pump
  • Do not add to DE slurry tanks
  • Make sure introduced at least 5 Meters upstream of filter
  • Diluting with beer lowers utilization and can result in precipitation of resins.
  • Product will freeze – must ship next day air during winter months

Package & Storage

  • 1 kg. containers
  • 20 kg. pails
  • Open containers should be used within 3-4 weeks and headspace purged using nitrogen (avoid using CO2)
