Definition
Stop depth is a physical endpoint defined by plunger position rather than taste feel or sound alone.
Why It Matters
A physical stop can be easier to repeat than a purely sensory endpoint.
Page Context
Stop depth is part of the Brew Supply AeroPress Wheel and helps brewers describe the physical plunger position where pressing stops.
