Episode notes
Brewing as Battery Building
- Flavor stability in beer begins in the brewhouse, like building a battery.
- Fermentation charges this battery, and time drains it, so start strong.
Trust Your Taste
- Don't rely solely on chemical tests or forcing tests for flavor stability.
- Real-world storage and tasting by a trained sensory panel are more reliable.
Oxygen Control
- Control dissolved oxygen (DO) and total package oxygen (TPO) diligently.
- Minimize aeration throughout the entire brewing process.
