Okay, so maybe I've gone completely off the deep end, but I've begun roasting Sarah and I's coffee at home. It all started on a car ride home from an outlet mall just before the holiday season came underway when I decided it would be cool to own a coffee roaster because aside from freshly roasted coffee for yourself you could custom roast it for the coffee lovers on your list. So I decided I'd keep a casual eye out for a cheap roaster on craigslist/ebay, but in hopping online and looking up info about home roasting it turns out the gateway roaster for most people is an old popcorn maker. Challenge accepted. I went to my (then) local thrift store, The Lucky Dog, and got an old air popper for five and a half bucks. From my research when selecting one the older the better as they tend to get hotter. I didn't have many options since they only had one on hand, but I figured I'd give it a go. I'm pretty convinced the one I ended up with must be newer since it doesn't get hot enough to go very far beyond a light roast and even that takes a little longer than most of the time charts I've looked at. Anywho, I did end up making coffee for people for Xmas, but never again. Birthdays perhaps, but the amount of coffee it took to even do little (adorable) tiny bags that would make a single pot for everyone took what felt like foreverrrrr. But I have been roasting coffee every Sunday night for Sarah and I, and for a weeks worth of coffee it takes around 45 minutes from getting everything out to putting it away, which I can live with most weeks.

I got my green coffee beans from smokinbeans.com where a 5lb bag clocked in a between twenty and thirty bucks. Aside from the beans and the air popper I use a measuring cup (1/3 seems to be about the right amount for the popper), a rubber spatula (both for the rubber part and for the wood handle), a mesh strainer, and a bowl.
If you're going to try this at home make sure there's good ventilation. Near an open window. Outside on a porch. In the past two months I can't even tell you how many times I've set off the fire alarm roasting coffee. Currently since I'm still in New England and it's hella cold out so I'm not going to open a window (spoiler alert to adult life: heat is expensive in the winter) I set everything up on a cookie tray on the stove top under the exhaust vent like so:
The bowl is there to catch the chaff when it flies off the coffee bean, it certainly doesn't catch ALL of it, but most of it for sure.
Once you turn the popper on and put in the beans in you want to make sure that the beans don't stop moving. I usually pour them in fairly slowly and they keep moving, but if they need a little help give them a stir with the wooden handle of a spoon or spatula.
I find that a little over six minutes is the right amount of time for how Sarah and I like our coffee. Below is an example of the chaff off a round of roasting:
Like I said I'm pretty sure my popper doesn't get quite hot enough, so I stick a rubber spatula over the opening for three to four minutes of the roast to try and trap a little extra heat in there. Once the coffee is done roasting it needs to be cooled off as quickly as possible, so I dump it into the mesh stainer and gently shake it around for a few moments.
While Sarah liked the coffee I was roasting she missed flavored coffee, which is what we normally were buying beforehand. The last couple of batches I added a little bit of vanilla extract and some cinnamon sticks to give it some flavor. Then more recently in addition to the vanilla and cinnamon I added coco powder.
Once the coffee is done roasting it does need to be in a container that will allow it to off-gas over night, I just keep the mason jar we store it in cracked open a little the night after I make it and then close it for real after I make my coffee in the morning. If you're a crazy person like me and want to try roasting your own coffee in an air popper I'll leave the links I used to figure it out below. See you next Tuesday!
