If you have a broad range of particle sizes when you broke up coffee, that's bad, because the very fine pieces will give up their flavor very quickly and begin to over extract. 00:00:57.170 --> 00:01:2.210 Add quite a lot of bitterness on then very large pieces won't extract properly. 00:01:2.450 --> 00:01:4.750 They'll end up making the cup a little bit sour. 00:01:5.610 --> 00:01:7.490 Obviously, anything in the middle should brew. 00:01:7.500 --> 00:01:14.450 Idea me pretty normally, but we'll get is some tasty coffee, some bitter coffee and some sour coffee all in one cup.
