Question: Can you ground coffee?
Document: This little grinder is great ! I read a couple of other reviews before buying. Yesit is a little difficult to open @ first. I loaded one nutmeg into the grinding areaand am storing other nuts inside the compartments. The size of the grounds is not asfine as I would like for coffee but works great when added into ground coffee for brewingand is fine enough for baking. It Is open on the bottem, so grounds can fall throughso I keep it is a bag. Glad  I made this purchase.
We have an old coffee grinder at our other house and it works like a charm. This was bought for my vacation home, and I should have bought another coffee grinder which continues to work like a charm after 10+ years.NorPro Spice Grinder for Nutmeg & Other hard Spices
Would be nice if they would ground up into the gadget itself.
love this, was looking at a Williams Sonoma, but didn't want to pay $25.00. This does the trick, enjoying the smell of the fresh ground spices.
A handsome toy and gift, considering most spices are already available in ground form.Otherwise item not worth the money.
I love freshly ground nutmeg and bought this instead of using the little mini grater. Well, it went into the trash. I was able to get one ground and tried to insert another for more than 5 minutes and it never locked!Love my little mini grater now!
I got this to grind stranger spices, i.e. long pepper corns. It does not make them into an expected dust-like-ground, its chunkier. It comes apart easily and there is room inside to store the spice your wanting to grind. The grinding handle at the top could have some more clearance, it has scrapped my knuckle a couple of times.
This is soooo easy - I store the whole nutmegs right in it. I twirl the handle, and voila! the excellent taste of fresh ground nutmeg, with nothing to clean and no knuckles to bandage. It's a little tricky to put the top on once a nutmeg is in the little slot to be ground, but that's the only problem. I've tried all sorts of hand mills.
At that point, cranking the handle turns the spices against the sharp slots in the bottom of the grinder, and ground spices fall through the slots.Because the slots are fairly wide, I would say black peppercorns are about the smallest seed you could use with decent results. I bought it to use for grinding allspice, which are about pea-size, and it works great for that. Nutmeg, which are even bigger, would be perfect.
I bought this to ground up spices like rosemary, thyme stuff like that. went to grind it and it didn't work. I believe it is probably meant for whole spices like cloves and allspice. Even for that though you still have to have a plate or bowl because the ground spices will come out of the bottom. The the whole spice goes in the mddle part and the outer part around the middle is pretty much useless.
Answer: I have never tried, and I would probably say no because it would be too time consuming.  It is not that large of a unit. Try a mini food processor or a real coffee grinder.
