Roasting Coffee at Home

Post by plainview » Thu Nov 02, 2017 12:54 pm

Over the years, I've used a number of different home set-ups for coffee roasting - some cheap, some expensive. But my current set-up is by far my favorite. Today, I use a heat gun with a stainless steel bowl. Some roasters refer to this setup as HGDB or heat gun dog bowl.

My small insulated bowl is partially lidded (home made), which allows me to regulate the temperature's rate of rise - if too fast, the lid moves slightly off, if too slow, lid moves slightly on. For me, it's all about roasting by sight, time and smell.

I load the pre-heated bowl with 5.5 to 7.5 oz of green coffee and stir with a metal ladle, turning over the coffee. My goal is to typically hit first crack at around 8 minutes 30 seconds to 9 minutes 30 seconds. I tinker with this time, depending on the coffee. Once I've hit my desired roast level, I dump the beans in a colander and cool by pouring the beans from the colander to a fresh stainless steel bowl and back again...over and over. Usually two minutes of cooling is fine, I don't like to cool the beans too quickly. The beans take about a day to rest, but I've found the peak flavor to be at three days off roast. Also, I buy my greens from Sweet Maria's.

Questions about coffee and coffee roasting?

My must haves:
Ladle, metal (I've charcoaled many wooden spoons)
Ski gloves (seriously)
Heat gun
Stainless steel bowl
Natural insulation material
Metal colander
Timer
Greens

For the roasted coffee:
Mason jars/lids (I usually wait 24 hours before tightening)
Funnel and scoop (makes life easier)

Really. I've never roasted coffee, but both of my grandparents did, and they both used wood burning ovens. They both did dark roast, also.

I plan to try it in our propane fueled Bertazoni oven.

Let us know how it works out, sounds great. One thing I forgot to mention, roasting coffee produces a lot of (fragrant) smoke. A lot.

There was a thread years ago in cps about this. It actually got me started with a hot air popcorn popper. Loved it. Might take a crack at it again (pun).

I’ve got an old metal mixing bowl. Do you think a propane burner (like people use for frying turkey would) would work as a heat source?

As long as you can control the heat, the burner should be ok. If the temperature rises too fast, the beans could end up being underdeveloped internally as well as scorched. But, if you find the sweet spot, then coffee's on.

My first roasts were on a stove top with a Whirly Popper. The Popper didn't last long, though. I moved on to other methods.

I passed it on years ago to someone who was interested in coffee roasting. At that point, I was exploring a Behmor* and no longer needed the popper.

Ah ha! I thought the popper died an unnatural death from being used as a coffee roaster!

Well that's a fancy roaster!

Wosbald used to talk about roasting coffee. Does he still do that?

Let's ask him....

Haven't roasted in quite awhile. There's no affordable home setup which would both give me the results I'd want and reasonably withstand (along with having replaceable parts) the rigors of roasting.

Otherwise, I'd love me a 12k Probat (or, dream on, Gothot).

This ain't to denigrate anyone's home-roasting. It demands some compromises vis-à-vis pro-roasting, but if you know about 'em and are willing to make 'em, it's a totally worthy endeavor.

I never thought about the roasting of coffee beans as such an elaborate process, but simply a lengthy one.

I was pretty young, but I seem to remember my grandmother roasting beans in a heavy metal pan or tray in her kitchen propane fueled regular oven, while she went about other tasks or while visiting, and occasionally stirring the beans, as you would when roasting peanuts or check mix. She would ask my grandfather for his opinion, and he would always say to let them go a little longer, to get a darker roast. The aroma in the house was incredible. Would have put Starbucks to shame.

With regards to roasting equipment, I've gone full circle. At first, my setup was very simple, just a stove top popcorn popper. Over the years, I used a succession of dedicated home coffee roasters - each one more expensive than the previous. My last big purchase was a Quest M3 with bean and mass thermocouples, running Artisan Visual Scope software along side my roasts. However, I retired my Quest some time ago and returned to bare bones method described above. While my results are not as repeatable as they were when I was monitoring roasts with Artisan, the beans are usually aways delicious.

this sounds like a fun hobby.

How often does a coffee lover roast fresh beans? That is... do you make a batch to last a week? A month? Three or six months?

Typically roast a pound of green coffee every week. With a 15% or so loss of moisture, around 12-13 oz of freshly roasted coffee remains.
