The Bloom Pour Over brewer is very different in important ways, all leading to even extraction and consistently great tasting coffee. The deep, flat brew bed, combined with the advanced micro-filter with 1502 holes, channel the water evenly through the coffee, releasing its true flavor. For other cone shapes, water exits on all sides, leading to some over-extracted coffee and some under-extracted, giving a different brew every time. For other flat bottom brewers, there is no deep bed and only a few exit holes, leading to inconsistent results and some over-extracted brew.
