Notes

Osmotic flow technique means maintaining a constant, thin stream of water rather than discrete pours. Keep the water level at about 1cm above the coffee bed at all times. This creates a consistent osmotic pressure gradient for the most uniform extraction possible. Requires a gooseneck kettle with good flow control.
