..when making manual drip coffee? I've found that the coarser the grind, the more times water should be poured through to optimize taste. When I've gotten extremely finely ground coffee, one time works very well (and in fact doing it more than once clogs the filter). With the drip grind coffee I'm currently using (Jim's Organic Coffee), I pour water in 2 times when I use 4-5 tablespoons of grounds - about 1½ - 2 ounces the first time, then 6 - 8 ounces. When I make coffee with 2 tablespoons or a little more grounds, I run water through 3 times - 1 - 2 teaspoons first, then 1 - 1½ ounces then 2 - 2½ ounces.
