One of my favorite hobbies is roasting my own coffee. In this instructable, you'll learn how to roast your own coffee (tastes way better than any other you can buy). I buy it green from a company called Legacy Coffee. You can order it green online from Sweet Marias.com. One of the reasons that I like to roast it fresh, is because I read somewhere that 2 weeks after roasting the coffee, it loses nearly 70% of it's flavor. Most store bought coffee has been sitting on the shelf for over 3 months. I'm not sure if this is true or not, but I do know that my coffee tastes a LOT better than store bought! You can buy green coffee for about $4.50 a pound (this is one pound at at time, buy in bulk and it gets cheaper pretty fast), so you save some money roasting your own too.
I can't really take full credit for this, I learned this from a friend, but it still might help you guys out.
Step 1: Supplies, Tools, and the Roaster
You will need to purchase a roaster. I have an old popcorn popper, a "Poppery II". It works great. You can purchase new coffee roasters online, but they coast over $200, when you can buy one that works just fine for about $30 on eBay. Just make sure that the popcorn popper does NOT have a screen in it! Which is why Poppery IIs are so good.
Also, you'll need some oven mits (so your hands don't get burned), coffee of course, and some cookie sheets. You'll want to work in an area that has a freezer near by.
