Hi there -- It occurs to me that men (well at least some men, like my hub) might indeed like & would actually use body scrubs.
In fact hub likes to keep a little jar of some sort of decently-moisturizing scrub on the kitchen, bath, and workshop sinks to use on his hands. Of course there are several premade hand products specifically made for workshop or garden or other seeeriously grimy/dirty hand situations, but neither he nor I like them because all the ones we've tried so far tend to kinda chew up & be quite drying to skin.
I'm not a toiletries or soap maker myself, but seems to me that coffee based scrubs should be reasonably easy to make with crushed or ground up beans plus either brown or white sugar ... annnd possibly some nonfat dry milk?
That would yield 4 possible scrub types or 'flavors' -- black coffee, coffee & sugar, coffee & cream, and coffee with cream & sugar.
Would these be merely joke gifts, or could they actually be 'helpful'? ... welllllll ...
Milk has quite an ancient reputation as a skin-helper -- remember Cleopatra and her famous milk baths? Today we know that the lactic acid could provide a bit of 'chemical exfoliation', which would help skin to accept moisture/moisturizing more efficiently.
As for sugar, well of course there are numerous sugarbased scrubs out there on the commercial market at this very moment -- mainly because it provides fairly effective (and fairly inexpensive) 'physical exfoliation' for skin.
I guess white sugar would probably be more 'realistic' or something in a coffee scrub, lol; but you might also consider using part or all brown sugar too -- perhaps especially the kind called 'turbinado'.
Regular brown sugar crystals are generally softer-feeling and less sharp than white sugar crystals. And unlike regular sort-of-powdery-feeling brown sugar, the turbinado variety comes in more-rounded & somewhat-larger pieces, almost like teensy river pebbles.
And finally coffee... The caffeine in coffee or tea used topically just might have some actual action... particularly for reducing the look of 'puffiness' or unwanted fluids.
When I was considerably younger, body wraps using coffee grounds were quite popular at home & at spas or salons, for temporarily smoothing out the look of cellulite on thighs/rear. And probably everyone's heard of putting steeped cooled tea bags on undereyes to help 'puffies' from lack of sleep, or allergies, or late-night partying.
Anyway! As I said, I'm not at all a toiletries/soap/candle/etc maker myself... but I did happen upon the following "recipe" which  sounds fairly easy to to do with no special supplies and  should be easy to adapt by using coffee-sugar-&/or-drymilk instead of the other scrub ingredients mentioned.
I'd guess you might be able to influence the end color by using good soap in white, tan, brownish or black (there actually is an old famous black soap long-said to be extremely skin-beneficial) -- and of course if the ground or crushed coffee isn't enough to scent the scrubs appropriately you should be able to add a bit of eo.
[[ By the way, in case you didn't know, the eo doesn't absolutely 'have' to be coffee, in fact I'm not even sure there 'is' a coffee eo, lol, though maybe there's coffee fo ... but ...
there are three spices which in small amounts work *very* well with & very much enhance the scent (and flavor) of just about any decent-quality not-pre-flavored coffee: star anise, &/or fennel, &/or cardamom.
They might possibly be a little easier to find in true 'essential oil' form, but if not, you could experiment with the ground or whole forms, And then of course there are alll the more-usual coffee scents/flavors such as vanilla, hazelnut, Irish Cream, etc etc]] http://recipes.herbalsoapsbyrj.com/recipes/category.php?CID=13
Mel's Fabulous Shea Scrub
Submitted by: Melanie Hayeshttp://www.bathandbodycollection.com
4 oz grated soap
2 oz shea butter
1 oz olive oil
1 oz liquid soap (optional)
1 tsp walnut shell powder or jojoba beads
Grate a 4 oz bar of soap (salad shooter works nicely, or for finer shavings, use a potato peeler). Put some soap shavings into an 8 oz container. Add shea butter, olive oil, and liquid soap as desired. Mix well with a fork or whatever you have to mush it all together - add in exfoliant (walnut shell powder, pumice, jojoba beads - your choice). Add more soap while mixing together to get desired consistency - I prefer a thick, almost creamy mixture. Put in the shower. Scoop and rub in circular motion to gently exfoliate and massage all while cleaning and moisturizing!!! I LOVE THIS RECIPE, it happened by accident, but it's the best I've ever made. TIP: Use a well scented soap and your scrub will smell nice without having to worry about too much FO/EO in the mix.
My own notes:
(1) I have nooo earthly idea what Mel means by using a salad shooter for grating or shaving... ?! ... but I'd say any kitchen implement, hand or electric, which will easily grate a hard cheese or a carrot would also grate or shave a soap. ... ...
(2) I'm definitely no fan of shea butter so if it were me I think I might experiment with cocoa butter instead. Don't much care for that either but at least its faint scent might be somewhat appropriate for coffee scrub, lol ...
*EDITED to add* this: Also, if it were me, I think I'd experiment with something 'other than' olive oil. My personal choice for a couple of reasons -- again, one being that it's perhaps a little more appropriate with coffee -- would be "green tea seed oil". A large health/naturals type grocery store such as Whole Foods should have it it in case your local groceries don't. (WF happens to be where we buy it).
(3) I know glass containers aren't exactly recommended for bathroom use, however, I also know that NOT ALL plastics are toiletries/cosmetics-safe. Now, I'm not sure if the following would successfully contain a scrub, but wonder if it'd be possible to experiment a bit with small-size "coffee bags" made from sturdy/heavy paper, carefully- & well-lined with waxed paper or clingwrap, with an inexpensive "coffee scoop" tucked inside? ... ...
and finally ... ...
(4) Here's a muuuch simpler but still cute and useful possibility:
You actually don't 'have' to 'make' a scrub.
Instead, simply prepare & combine as desired any or all of the three *dry* ingredients -- coffee, sugar, dry milk -- which provide a scrubbing action.
Unless you want to try adding something else *dry* such as ground cardamom or fennel, for example, don't add eo or fo, just let the actual coffee scent be.
Put the dry scrub ingredients into the smaller-than actual-size, well-lined (i.e. hopefully moisture-proof) "coffee bag" along with the "coffee scoop" -- -- add a good secure closure, perhaps like those sturdy thick twist ties that often come on real coffee bags -- -- call it Instant Coffee Scrub (or whatever you like!) -- -- and add directions such as this:
In palm, mix 1 or more scoops with a little body wash, liquid soap, or light lotion. Scrub skin gently; rinse well. Keep bag tightly closed.
This way, people can use the scrub with products they already have.
If the thought of possible moisture collecting in a bag containing dry milk bothers you -- I can understand this as it slightly disturbs me too -- simply leave that out & just combine coffee & brown+white sugar.
Btw, turbinado brown sugar is considerably less prone to moisture-hardening than regular brown sugar -- but there's also a special type of regular brown sugar which should be readily available in any large grocery store & which claims to stay pourable and not to harden (in my experience the claim is reasonably accurate ... and anyway you won't be making 'humongous' bags that might sit in damp bathrooms or kitchens for a long time.).
