Special (AQ) Reporting - % area,mg/mL, mg/100g, & Varietal Comparisons


Sample size needed: 5 oz. (150 grams) fresh wet, dried whole, or pellets.


In addition to the hops alpha & beta acids, you will receive the total oil content (mL/100g), and a portion of the distilled oil is analyzed by GC (Gas Chromatography). This will provide results for the relative %, mg/mL, and mg/100g of each of the volatile oils: used to help identify varieties, batch adjustment, fingerprinting, or process preservation of aroma hops. For the Aroma Quaility (AQ) you will receive a special report that will compare the composition of your hop oil to the expected standard for the specific variety. NEW & never before offered!

Determination of the total hops essential oil content & oil profile by GC (Gas Chromatography)

​​(Hops-13)  ASBC method to determine the total amount of essential oil by steam distillation.  Samples are boiled in a 12 liter flask and the distillation apparatus separates and condenses the hops oil.  Results are expressed as mL of total essential oil per 100g of hops.  (mL/100g).

(Hops-17)  ASBC method to determine the relative percent of each major essential oil compound by GC-FID.  Portions of the hops oil are treated and injected into a gas chromatograph, volatilized, and separated.  The response of each compound will be expressed in terms of a % of the total oil.   

(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.
