Hop Analysis #1: Alpha and Beta Acids

This spectrophotometic analysis will determine the percent (%) alpha and beta acid content in a dried whole cone or pellet hop sample. It uses the ASBC's Hops 6A Method of Analysis. Sample size required: minimum 15 grams of a representative dried whole cone or pellet hop sample. Please note, whole cone hops must be at a moisture content between 8-11% or else to analysis cannot be performed.
$60.00

International Bitterness Units (IBUs)

This analysis determines the International Bitterness Units (IBUs) of your beer product. It uses the ASBC's Beer 23A Method of Analysis. Sample size required: two duplicate 12 oz. containers per analysis.
$55.00

Grist Analysis

Diagnose and prevent brewhouse problems with a grist analysis. This service includes an analysis with the following sieve sizes: #10, 14, 18, 30, 60, 100. Sample size requirement: 1 pound of grist in a zip-lock bag.
$75.00

Nutritional Analysis of Beverages for Labeling

This service option is perfect for the individual looking for a nutritional label for their beverage product (beer, cider, kombucha, juice, etc.). Results meet labeling requirements set by the FDA and include the following analyses: Ash, Moisture, ABV, Calories, Calories from Fat, Total Fat, Saturated Fat, Trans Fat, Cholesterol, Sodium, Total Carbohydrates, Dietary Fiber, Sugars, and Protein. Sample size required: two duplicate 12 oz. containers per analysis.
$630.00

Total Plate Counts

This analysis is for the customer looking to assess cell count numbers only or total plate counts (TPCs). Results reported are the total number of organisms in a 100mL sample. Samples are sterile membrane filtered and then grown on UBA (or another media upon request) under aerobic and anaerobic conditions. If the sample is unable to move through the filter then spread plate methods are utilized. Sample size requirements: Two 12 oz. duplicate containers per samples needing analyzed.
$40.00

Lactobacillus/Pediococcus Detection in Beer

This analysis detects Lactobacillus and Pediococcus species in beer samples using Hsu's Lactobacillus and Pediococcus (HLP) media. Presence/absence results are provided for in-process and finished product samples. Sample size requirements: two duplicate 12oz. container per sample needing analyzed.
$30.00

Beer Contamination Detection by Sterile Filtration

This comprehensive microbiological analysis utilizes sterile filtration and a variety of selective media in order to detect and quantify potential yeast and bacterial beer spoilers. A 100mL sample is filtered and grown on UBA, WLD, MRS (with cycloheximide), Lysine, and LWYM under aerobic and anaerobic conditions. Any growth is then catalase tested and gram stained. Results include total Colony Forming Units (CFUs) per 100mL sample, CFUs per growth formation and microscopic pictures of the growth. If samples have a high biological load or are unable to move through the filters, spread plate methods will be utilized. Sample requirements: three 12oz. duplicate containers per sample being analyzed.

MALDI-TOF Microbial Identification Analysis for Bacterial Isolates

Do you have an isolated bacterial culture that you'd like to know the identity of? If so than this analysis may be of interest to you. The MALDI Biotyper uses MALDI-TOF (Matrix Assisted Laser Desorption Ionization-Time of Flight) mass spectrometry to identify microorganisms by analyzing ribosomal proteins that create a unique fingerprint. Identification to the species level is achieved by comparing the sample fingerprint to a library of more than 5000 fingerprints. This analysis is for isolated bacterial cultures only due to the current limited yeast library. Isolated samples may be submitted on plate media or in broth media and must be shipped overnight on ice. Sample size requirements: One isolated sample shipped overnight.
$50.00

Beer Contamination Detection by PCR

This lab analysis utilizes the Pall Genedisc Cycler V3 Unit and Ultra-Lyser. Finished beer, yeast slurries, or any samples taken during fermentation can be analyzed. Pasteurization samples will need an additional enrichment step to increase sensitivity. See below for a list of species identified through this PCR analysis. Sample size required: four 12 oz. containers of finished product per analysis.
