Hop Acids & HSI
This Basic Test Package includes:
% alpha acids, cohumulone, % beta acids, colupulone
Values given (as is) & at 10% moisture
FREE moisture/dry matter
HSI (Hop Storage Index)
Sample size needed: 1 oz. (30 grams) fresh wet, dried whole or pellets
(full sandwich Zip-Loc)
Sample size needed - Extracts - 1 gram
This is the ASBC preferred International Method for alpha/beta acid analysis. Samples are extracted by solvents, and a portion is analyzed by HPLC (High-Performance Liquid Chromatography). This allows us to separate the acids, use a special qualified standard, and provide the % cohumulone and colupulone content.
Results compare very well to samples previously analyzed by the spec assay (Hops-6A). Works great for all types of hops samples. Fresh, wet, dried, extracts, etc.
Includes: Hops-14, Hops-4C, Hops-12

If you are interested in testing hops for alpha acid content, the International ASBC accepted method works best! Determination of the total hops alpha & beta acids by HPLC (High-Performance Liquid Chromatography)
(Hops-4C) ASBC method for the determination of moisture content utilizing our low temperature drying oven to preserve the volatile essential oil content that is not considered water, providing more accurate results. This value is important as it allows the grower/producer to convert a submitted "wet" sample to a theoretical alpha/beta acid content of the hops at your finished drying moisture content, typically ~10%. Results are provided as % moisture and % dry matter.
