Worm Food from Coffee Shops
I am always looking for feedstock for my worms. While it’s great to feed them all of my food scraps, I also enjoy taking the others’ “trash” out of the wastestream. This is especially true if the waste I’m removing is good for my worms. As a case in point, coffee grounds are a great feedstock: “coffee grounds are excellent, as they are high in N, not greasy or smelly, and are attractive to worms” (link to pdf).
If you don’t drink that much coffee, these grounds typically free from coffee shops. I don’t typically haunt coffee houses, but I’ve walked in and asked at four different shops now, and gotten a positive response. How I got the grounds varied. In one Starbucks, I found a bucket with bags of grounds all wrapped up nice.

Another Starbucks just gave me a garbage bag full of grounds. I went to a independent coffee shop in the morning. I left a five gallon bucket with my name an number on it and was able to pick up 4.5 gallons of coffee grounds later that day.
The worms haven’t had any trouble with the grounds. As a matter of fact, the grounds disappeared into the worm bedding fairly quickly.
If you’re looking for something else to feed your worms, and have easy access to a coffee shop, consider asking them for their used grounds.
