I have a Bodum French press and I want to buy a sieve to sift my grounds so I actually have coarse grounds and no fines. What size coffee grounds should I aim for? These sieves are quite a bit of money so I would only like to buy one.

I have heard that 850 microns or a #20 sieve does the job. But would I be able to go smaller? Rather have a coarse grounds then fines in my coffee.

I've got a #20 and think it's a little too aggressive (see here, for example). Looks like Nick Cho's been playing with a #50 lately (link). Maybe try his way or split the difference? You can find good deals on gently used sieves on eBay if you're patient.

Dear 123,
Pardon my butting in.  Even though you have a Bodum, if you want to cut the sludge, it would make more economic sense to buy an Espro French Press than an expensive sieve.  You could always experiment with a sieve if you happened upon it cheaply on ebay.  The sieve that you would buy could conceivably be used for pourover as well as FP, and not appropriate for espresso grind, but why not spend much less money to get a double-filtered FP unit?

Nothing against the Espro, but fines will overextract whether or not they make it into the bottom of your mug.

So I tried using just a mesh cooking strainer to sift my coffee grounds and if I had to compare it to a # sieve it would be a #20 or larger (have some very course grinds now).

But when I went to make my cup of coffee this morning I still had that bitter/silty taste from the fines in there....I also only let the press sit for ~3 min. So either I need to let the grinds steep longer or......what could be causing this off taste?

I was so excited to try my newly sifted grounds only to find that it was a big disappointment!

P.S. This whole experimental thing has me drinking way too much coffee!

Your name speaks for itself, you are the Aristotle of coffee.

I will try your advice you mentioned. I can tell you right now I am doing a few things wrong, biggest is probably the water temp. I just pull it off the stove from a roaring boil straight into the press.

However I think my problem is coming from the fines of the grind. Even though I have sifted the grounds I am still getting the same amount of sludge  at the bottom of the cup. And when I say sludge I mean SLUDGE!

What grinder are you using, and how many pounds of coffee have you put through it?
