A broad quality-control perspective; not every treatment is desirable for flavor-rich whiskey.
PDF116 / printed91. Rechecked quality-chain discussion and opening of section3.5. Later pages develop individual treatments. Reducing congeners may suit vodka while removing desirable whiskey character; quality is not simply lowest concentration.
The chapter argues that spirit quality begins with crop cultivation and continues through harvesting, storage, processing, analysis, and control of undesirable compounds; it then introduces filtration, freezing, and adsorption as tools that can alter volatile and nonvolatile composition.
