Hey everyone,

Jeff and I wanted to give you an update on where the science stands. After doing some troubleshooting in Austin, Jeff has an optimized souring method in place in at Blue Owl Brewing, and we're in the planning stages for the actual experiments. After a few more pilot runs, we're going to try to get Jeff in my lab at IU to generate, harvest, and process all of the samples together.  We'll certainly keep you posted with all of our new developments.

I also wanted to thank some new industry supporters, who in addition to donating money, have also donated some reagents to us. As you can see in the picture above, the great folks at Zymo Research sent us a kit to collect DNA for the deep sequencing part of the project, and they've also offered to perform the sequencing, #booyah! Aside from being yeast-friendly and employing lots of beer lovers, Zymo is getting into the microbiome game, and they're excited about our project. We're hoping to generate some great data together that they can highlight in promotional material for their microbiomics products.

We've also been offered NMR analysis of our samples by Process NMR Associates in Connecticut. These guys can do some amazing work to quantitate organic acids and other constituents in our sour samples. They're active in the fermentation industry as a whole, having examined beer, wine, kombucha,and other fermented products. I'm really looking forward to seeing what they technology can do with our stuff.

Anyway, many thanks to them and the rest of you. Cheers to Friday!

-Matt

    Hey Matt. This is all really great to read. Question: is there room for other breweries to somehow get involved? Thanks - Brenton

    Brenton, I guess it depends on what the breweries want to do. They can donate money to the project by donating directly to my lab at IU (which is also a tax write off, #booyah), or they could potentially get involved in some of the technical stuff. If you know of anyone who's interested, they can email me at bochman@indiana.edu. Thanks!

About This Project

Sour beers are likely the original beer style and have made a recent comeback in terms of popularity among craft beer enthusiasts. They are made with a bacterial and fungal mix rather than pure cultures of Saccharomyces. yeast as in typical ales and lagers. However, the suite of different microbes and their relative abundances during the course of souring and fermentation remain a mystery. We aim to map part of the sour beer microbiome and identify the organic acids these microbes produce.

Blast off!
