Fold the seam on your Hario #2 filter and place it in the brewer. Rinse filter and discard water.
Begin timer. Bloom with 50g of water. Stir.
At 40 seconds, begin the fill pour with steady, concentric circles. Start from the center, slowly spiral out to the edge, and then back to the center. Repeat this method for the entire brew, until the water is about half an inch below the rim of the filter.
Finish pouring all 375g of water at around 1:40 - 1:50. Give the brewer a gentle swirl and allow the rest of the water to pass through the brew bed.
