The Cultured Guru School of Fermentation

Understand the microbes. Master fermentation.

Even if you tried fermentation before and failed, even if you’re scared of microbes and fermenting at home, I have the skills and education to guide you to understand, embrace and appreciate the microorganisms of fermentation and the powerful foods they help us to create.

This was such a fantastic class! Kaitlynn is a good patient teacher, and I think it's awesome that she not only shows us how to ferment, but also tells us the science behind it!

I loved this class and I love the yogurt we made. I am continuing to make more and love that the process is so easy and the reward so quick.

Really great class. Enthusiastic instructor with lots of knowledge of fermented foods. I'm in my second batch of yogurt, and I'm determined to make water kefir.

Natural fermentation precedes human history, we know. Since ancient times, humans have exploited the fermentation process. We think it’s only reasonable that in our modern times, we respect the microbes, and choose to understand them in order to harness fermentation in the healthiest way possible. That’s why we created our School of Fermentation!


I’m a microbiologist (BSc Microbiology, LSU) certified in Food Safety and Preventive Controls. Food microbiology is my jam. I love teaching people how to have a holistic view of the microbial ecosystems that shape our foods, lives and planet.
