I grind mine up prrrrreeeeetttty small. I wouldn’t say too coarse…even when I grind them too much they rarely slip in. So I get greedy and grind them a lot. I guess I’m just one of the lucky ones. lol
A coarse grind works best for the French Press. This will ensure that the mesh screen will filter the coffee grounds and separate the liquid from the sediments.
Use a coarse grind and a long steep. I let the coffee steep for a minimum of 5 minutes before pushing down the plunger, usually I go for 8 minutes or more depending on how much bean is in there.
