Hand coffee grinding powder to brew coffee

Recently, the days of returning from ultra-fine coffee powder to ultra-coarse coffee powder are very painful. under normal circumstances, the hand coffee mill is relatively thick, and it takes 20 to 30 minutes to reach the level of visual fineness. Just imagine, in a short period of time, the coffee essence in the middle of coarse coffee particles can be extracted by simple hot water. The taste of hand-ground coffee powder is relatively thin and astringent.

Recently, I use this single cup of tiamo coffee to simply make coffee.

The coffee powder ground by hand coffee is thicker and there will be more bubbles; maybe this bubble does not come out of the coffee powder, but the air between the coffee particles expands when heated; the overall expansion of ultra-fine coffee powder is very small after flushing water.

Hand mill normal grinding, grinding 1 person coffee powder for 10 minutes, it is relatively thick.

Hand coffee rough grinding coffee powder after flushing bulge is very obvious.

Close shot of hand-ground coffee powder is very thick, seen from a distance is also the particles of white granulated sugar.

It takes 10 minutes to grind your hands like this.
