Notes
Place 700g of large ice cubes in a large pitcher before pressing. The 1:1 water-to-ice ratio ensures enough ice survives for proper chilling. Medium grind extracts more efficiently in the reduced water volume. The Hoffmann no-plunge technique works well here for cleaner results. Press just to the surface and pour over ice immediately.
