Exam Focus
- Explain aging as a brewing analysis topic within Processes.
- Compare maturation in tank, package, wood, or cellar by oxygen exposure, temperature, time, alcohol, residual extract, microbes, and flavor trajectory.
- Select beers suitable for aging and define sensory checkpoints that distinguish positive integration from oxidation, autolysis, or decline.
Core knowledge
- Aging vessels include stainless steel, new wood, used spirit or wine barrels, foeders, and other wood formats.
- Wood can add vanillin, coconut, toast, tannin, oxidation, and previous-liquid character; microbes in wood can add acidity, funk, or complexity.
- Oxygen ingress, surface area, contact time, temperature, and fill history control aging impact.
Study application
Connect vessel history and oxygen exposure to aged-beer flavor development.
