Coffee roasting

[Ecky]

The second batch I roasted ~6 minutes (I know it's not going to be comparable from machine to machine) and visually looked somewhere a bit past a FC+, but did not taste that way.

The third I pulled off at 5 minutes, and while it looked like a FC, my grinder struggled a bit to grind it (I used to have a Rocky but sold it along with my espresso gear a few years back). It tasted much lighter than a FC, however.

This time around I decided to try my IR thermometer. I'm seeing around ~410° at the 5 minute mark, and ~420-430° at the 6 minute mark, with 3 ounces of a Guatemalan.

So maybe the color isn't too far off. I'm guessing the beans are probably a bit dark to start with because they're older. Shouldn't take me too long to go through 4lbs at this rate though.

A brief clip for anyone curious. Just put the beans in, stir for a few seconds, then wait:

The issue I have with timing roasts: time is dependent on input temperature.

I roast outside and yesterday was 30 degrees so it took 15 minutes to get to FC (406 degrees) At 70 degrees it takes 6 minutes to get there and !SURPRISE! It wasn't linear. The upside: @ 30 degrees there is virtually no after cooking, the beans go cold really fast so roast temp looks like internal temp after a moment in the cooling pan. Hmm maybe I should get an IR temp device if I can believe you look at bean temp instead of air flow temp.
Does your roast guide have temperature addendums like the download @sweet Maria's? I think color is too imprecise but possibly because of my color blindness. I cant see any change until about 390 degrees when the beans start turning brown

The guide included didn't have a temperature reference.

I found There are several. Here's the easiest "https://library.sweetmarias.com/how-...our-own-coffee

Do you have house plants ?
Do you want even more control over your coffee ?

You could buy a sapling already started .. or .. You can plant a few green coffee beans (which is the seed of the plant) to try and get them to sprout. Once started it will take a few years before a sapling matures enough to bear fruit.

I have a dwarf coffee tree as a house plant .. it would no doubt do better in some outside hawaii like climate , but here in RI it does grow and give 30-40 coffee cherries (2 beans inside each cherry) each year.

The tiny coffee flowers that come just before the cherries are also a nice cute touch. Only a very light (barely detectable to my nose) fragrance.

MIGardener has some good / helpful youtube videos about it.

Nice but I go through about 52 lbs a year so looking like I need my 1/4 acre backyard full of mature trees in a greenhouse that's temp controlled to get erratic yeilds and flavor profiles

Gardeners are optimists.

And the ultimate optimist is an 80 year old that plants an oak tree for his hammock support.

That's one option.

Another option .. if you want to grown your own coffee in your back yard .. in a colder climate than conventional coffee trees will tolerate .. Acorn Coffee

Mature Oak trees don't need the green house .. and they produce prodigious amounts of acorns.

I'd never heard of such a thing.

Where I live, I have several hundred mature sugar maples on my 1.x acre property, and I have to say, tree sap is also rather nice.

It isn't coffee, however.
