Orea Z1 Orea by Orea

Orea's Z1 guide adapts Tetsu Kasuya's Four Six method to the brewer with five circular pours. The early portion shapes sweetness and acidity while later additions tune strength, producing a customizable cup with clear, deliberate balance.

Notes

Use the first two pours to tune flavor balance: favor the earlier pour for brighter acidity or the next for more sweetness. Keep the final three additions even, changing their cadence to adjust strength without disrupting coverage.
