What can you expect?

Please ensure that all samples for testing are delivered to our lab by the days and dates indicated below so that we can ensure a timely response. Hop samples will be processed in the order they are received. During the harvest season, please deliver samples to us by Wednesday each week to ensure results by the following Friday.


Hops samples should be vacuum sealed, cold-packed, and sent overnight to the following address:

Hand-deliver your beverage sample(s):

Drop-off will be at the more protected lower (west) entrance of the Food Research Lab (see map below). We recommend entering from Pre-emption Rd if possible.  As you turn onto Collier Drive, Food Science is the second building on the left.  As you pull into the parking lot, there is an overhang all the way to the left.  Inside, a red cooler will be placed at the top of a set of concrete stairs to receive your sample. Place your sample in the cooler, sanitized if possible. There will be a phone number listed on the top of the cooler. When the drop-off is completed, send a text message to that number letting us know it has arrived. If a text is not possible, email us ASAP.  Hop sample drop off Monday-Wednesday 8am-4pm.

Hops Analyses (Dried Hops)-We are currently unable to analyze fresh (wet) hops samples

Alpha and Beta Acids, Hops Storage Index, Moisture - $30

  • Alpha and beta acids are indicative of harvest maturity and characteristic of hop cultivar.
  • The hops storage index (HSI) is used to estimate alpha and beta acid loss due to storage and handling.
  • Includes: 10% moisture adjusted acids content (%) and moisture/dry matter (%)
  • Sample Size Needed: 10 grams 

Moisture - $15

  • Hops moisture (commonly reported as percent dry matter) is an important value for harvest determination.
  • Drying hops to their ideal moisture content (8-12%) maximizes hops quality.
  • Sample Size Needed: 10 grams

Total Oils - $30

  • Hop oils contribute aroma to beer, and oil content can be a quality indicator of hops samples.
  • Includes: 10% moisture adjusted total oil content (mL/100 g hops) and moisture/dry matter (%)
  • Sample Size Needed: 100 grams

Brewing Quality Package - $60

FOR FINISHED (DRIED/PELLET) HOPS ONLY

  • Includes moisture, alpha and beta acids, & total oils
  • Sample Size Needed: 150 grams

Sampling instructions for dried hops:

  • Representative sample (in “to be sold” condition)
