Definition
Bloom water is the first staged water that starts saturation and degassing before the main extraction load is added.
Why It Matters
Bloom size can change wetting completeness, heat retention, and early extraction progression.
Page Context
Bloom water is part of the Brew Supply AeroPress Wheel and helps brewers describe the initial water used for wetting and gas release.
