We offer consulting services to help you with your fermentations, brewing, and quality control and assurance practices. We can offer guidance on how to best operate a quality control laboratory at the brewery of your specific size, what tests would make sense and what critical control points to apply.

We were one of the first to isolate novel strains for beer brewing purposes, and we have isolated and banked numerous strains for breweries interested in their own house strain. Yeast isolation and testing can be tricky, and we gladly discuss with you options to affordably capture, isolate, test and bank strains that will set you apart.

Interested in a second opinion? Everyone is proud of the beer they brew, and It can be tricky to get an in-house objective opinion when it comes to beer. At Jasperyeast we have years of brewing, as well as GABF and BJCP judging experience, and can provide honest, useful feedback.
 

Abnormally high attenuation? CO2 levels slowly increasing in your packaged product? The presence of S. cerevisiae var. diastaticus in your beer can be a true headache. Using our own optimized sta1 primers, we can quickly detect the presence of the sta1 gene in a biological sample. If necessary, actual expression of the diastatic activity can be confirmed by using bromophenol blue starch plates.

Do you have a house yeast that you have kept alive for so long you lost count of the number of generations? Has your yeast strain positively changed in performance and you want to capture a snapshot so not to lose this strain? We can bank any yeast for you for a nominal annual fee. This fee is waived if 20bbls of this strain are ordered once a year. 
 

At Jasperyeast, we can test for microbial spoilers using various media (Lin's Wild Yeast Medium (LWYM), Lin's Cupric Sulfate Medium (LCSM), Lee's Multi-differential Agar (LMDA), Universal Beer Agar (UBA), Hsu's Lacto/Pedio (HLP), Wallerstein supplemented with cycloheximide (WLN+), Lysine medium and starch bromophenol blue plates. These media cover most beer spoilers.
