Default Coffee Roaster for WFO

If anyone is interested in roasting coffee beans in their oven, I attached plans to make a simple coffee roaster (at least I think it's attached). It is easy to make and very inexpensive (less than $20). Unroasted coffee beans will cost you about $ 6/lb.

I started roasting coffee over a year ago and cant stop!!! It is a lot of fun and makes for some good bonding time with your oven. Oh, and the coffee is fantastic!!! However, it does get expensive when you end up giving all of your fresh roasted coffee to all your friends, neighbors and family.

Very nice graphics, it might be worth a try, how hot do you think your oven is when roasting? If I heat saturate for 2 hours and then still have live coals I will be in the 800F range.

Chip,

It is pretty hot in there when I roast...probably about 750-800 sounds right. How big is your oven? One thing you have to be careful of is to keep the coffee from getting to close to the open flame.

I have a 42 inch ove, so there is a lot of room to put the fire around the perimeter. If you have a smaller oven, you may not want to have the live flame going, just glowing coals.

Mine is also 42 inch so I could follow your plans quite closely. Thanks for the heat update.

Have you thought of using some type of stand to make it easier to hold the basket off the floor and still be able to rotate it?

Good idea.

Originally I planned a rotisserie, but quickly realized that I needed to be able to quickly take the basket in and out of the oven to check on progress....You will find that when the beans begin to roast, there is a short window of opportunity.

I just rest it on a log in the entrance way as kind of a fulcrum. It works fine and I since abandoned the idea of a rotisserie (will just get in the way).

BTW, thanks for your interest. I am hoping to recruit some coffee roasters here on the forum...I thnk it is a great application for an oven and it really is a lot of fun.

Let me know how it turns out. I just roasted 5 pounds of coffee yesterday and this batch is fantastic.

You will need to get yourself a coffee grinder if you dont already have one. I bought the KitchenAid...works great for me.

If you like stong coffee, espresso, or cappacino, you will want to get a "Bialetti 6800 Moka Express Stovetop Percolator"....they call it a poor-mans espresso maker and it costs around $30...great little device.

This sounds awesome. Thanks for the detailed plans. I cannot wait to try it out and have been wondering for some time what it would be like trying coffee roasting in the oven. Now that winter is here in New York I need that coffee to keep me out by the oven.

I had a sample of roasted beans evaluated and "scored" by a professional......based on his recommendations, I am going to revise the design of the roaster and (1) add an agitator inside to help move the beans around the basket. (2) revise my technique to try to rotate the beans more...maybe a support like mrchipster suggested above....maybe add a spit motor. most important, reduce the heat. I had suggested an active fire..this might be too hot after all. ..maybe just glowing embers. Cant wait to roast again with my new-found knowledge.

I was thinking of making up 2 little tripods that you could put inside the oven that you could rest a tandooried chicken on a skewer on
2 removable 3 legged metal stands one front one back with a u shaped top.
Something like this would work to rest your roaster on and spin it in.
Just need a bit of straight metal extending from the sieves.
Possibly just using one at the rear so you could move your roaster in and out to check progress easily.
