Wave Filter with Coin

Graycano Misc pourover by Graycano

Graycano credits Basic Barista with this Coin setup, pairing the adapter with an Origami Wave 155 filter for a measured bloom and even pulses. Slower, distributed flow shapes a sweet, full-bodied cup with a rounded finish.

Notes

Seat the Wave 155 filter evenly in the Coin and rinse thoroughly so no folds obstruct its outlets. Start coarser than for the bare Graycano, keep each pulse centered, and let the water fall close to the bed before adding the next pour. If the cup tastes heavy or dry, coarsen further rather than pouring faster.
