Alpha Extract 20%

Description

Foam is an important visual representation for quality beer, but some beer styles are decidedly foam-challenged. Some recommended advanced hop products to help meet this challenge are Alpha Extract and Tetra Extract.

Alpha Extract is a concentrated, aqueous solution of α-acids ideal for improving beer foam and lacing post-fermentation without contributing any added sensorial bitterness to the final product.

Advantages

  • Foam stability
  • Foam lacing & cling
  • Anti-microbial

Usage & Methods

  • ≈6 grams of product per bbl. for each ppm
  • >5 ppm of alpha acid can improved beer foam in beers that are 15 IBU’s or less. For beers greater than 15 IBU’s, Tetra should be used
  • Include link for bench-top testing in bottles or kegs
    1. Good – add product to empty vessel and push with nitrogen (NOT CO2) into beer line when starting to fill tank
    2. 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
    3. 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.

Notes & Suggestions

  • 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
  • Perceived bitterness is 0.1x that of Iso-Alpha Acids and very smooth
  • For dry-hopped beers, Tetra Extract is suggested

Packaging & Storage

  • Only use nitrogen to purge container headspace free of air. CO2 will lower the pH of the dilution causing the product to become insoluble.
