Osmotic Flow S

Clever Dripper S Clever by Clever

The Clever brand's Osmotic Flow S uses the small dripper as a hybrid, beginning with valve-open percolation before changing to immersion. It seeks the clarity of flowing extraction with added body and complexity from steeping.

Notes

Keep the initial valve-open pour gentle so channels do not form in the compact bed, then close for immersion before the bed dries. If the finish is muddy, shorten immersion or reduce agitation; if it is thin, grind slightly finer.
