We went to the Craft Brewers Conference in Philly, gave a talk with Dr. Glen Fox, and realized one thing: Brewers have a lot of questions about yeast nutrition.

In this episode, Mark and Richard recap their recent CBC session on Yeast Nutrition, Zinc, and FAN. Because the live Q&A was so packed with "deep-cut" technical inquiries, we decided to bring those questions back to the lab for a dedicated Yeast Nutrition Lightning Round. We move past the "add a spoonful of nutrient" advice and get into the complex chemistry that actually dictates fermentation success.

We break down:

  • The FAN vs. YAN Debate: What are you actually measuring, and why does proline matter?

  • Zinc Security: To sterilize or not to sterilize? Plus, the risks of metal-induced oxidation.

  • Nutrient Timing: Why TOSNA is great for mead but might not be the right move for your Lager.

  • Pro-Tips for Repitching: How feeding your yeast today changes the health of your pitch next week.

  • Non-Alc & Hop Creep: Adjusting your nutrient strategy for modern brewing challenges.

Resources: * Brewers Association members can find the full talk recording and slides with Dr. Glen Fox on the BA website.
