In 1872
, John Ewald Siebel opened the Siebel Institute of Technology to meet the analytical needs of brewers in the United States. Since that time, Siebel Institute has grown into a world leader in brewing industry laboratory services.

Located in north-suburban Chicago, our Siebel Institute Laboratory Services division features state-of-the-art facilities that allow us to offer the widest range of brewing-related tests available anywhere. We employ techniques that are industry-proven, using standards set by such organizations as the ASBC and EBC for testing and reporting. With modern equipment operated by the industry’s most experienced staff, the scope of our abilities includes:

  • Extensive taste panel facilities for beer evaluation

  • Microbiological assessment of beer and yeast

  • Analysis of raw materials including malt, adjuncts, hops and water

  • Specialized beer analysis of compounds such as diacetyl, DMS, esters and fusel alcohols

  • Certified analysis of alcohol, extract and calculated values

Most importantly, we provide our customers with an unparalleled level of service. We can consult with your brewery to help you decide which services are right for you, and when your results are ready, we will help you interpret their meaning. Combine all of this with fast turn-around time and affordable pricing, and you will understand why Siebel Institute is the first choice of the world’s leading brewers for their analytical service needs.

NEW! Important Testing Service for Stale Flavor Compounds in Beer

Brewers face an ongoing battle to keep their beer tasting as fresh as possible for as long as possible. Stale flavors caused by oxidation damage in beer can result in customer disappointment and, ultimately, lost sales. Certain carbonyl compounds, particularly aldehydes, are known to play an important role in beer staling. The Siebel Institute Laboratory Services division is pleased to announce a new service for analyzing “staling aldehydes” that will give you critical information about the staling that has occurred in your beer. We first analyze a “fresh” beer from your brewery for aldehydes as a reference standard, and we can then analyze similar beers from the trade (or beers that you subject to “abuse”), comparing them to the reference standard for flavor stability to see how they have aged.

This is an immensely valuable service for every packaging brewer concerned about product quality. To find out more about our new staling aldehyde testing service as well as our full range of Siebel Institute Laboratory Services, contact Lyn Kruger at lkruger@siebelinstitute.com.
