Brewing Basics
Drawdown
The total time it takes for brewing water to drain through the coffee bed in a gravity-fed percolation method. Drawdown time serves as a practical indicator of grind size, dose, and overall extraction.

A target drawdown for a single-cup V60, for example, is typically 2:30 to 3:30 depending on dose and recipe. If drawdown runs long, the grind is likely too fine or the bed has clogged with fines, risking over-extraction. A fast drawdown suggests a coarser grind or channeling, leading to under-extraction. Tracking drawdown time is one of the simplest ways to maintain brew consistency.
