The post below and the attached photos was written for the Behmor Home Roasters Facebook group, but I thought it might be useful here.
These are notes on three roasts of Peru Ceja De Selva AAA beans: #267 on 21 March 2020, #337 on 26 May 2021 and #347 on 03 August 2021. I have notes like these for all of my roasts since 01 January 2011.
In each case you will see the roast number, the beans, the date, the weight in and out and percentage drop, followed by the setting used.
In the columns of the table you find:
- The initial time on the machine.
- Info on C1 (first crack); the three times are: start, rolling and end (a negative number indicates a time into cool down)
- Any adjustment made to the roast (e.g., time added or deducted).
- The final length of the roast.
Below the table in brackets is the time after C1 or rolling C1 at which I’m aiming to end the roast and start cool down along with the intended colour on the @CoffeeSnobs colour scale.
Notes:
- I never intentionally roast into C2.
- Even though the recommended weight is 1lb or 400g, I always roast 500g as my green beans come in 2.5kg bags; this has never caused me any problem.
- “Roast Comments” is self-explanatory. The number in a circle at the bottom of the page is the actual colour of the final roast on the @CoffeeSnobs colour scale.
- Roast #267: this is in an original 1600 (the Australian model using 240v power). I used a 1P2B++ setting and added time to ensure that the roast stopped 1’30” after rolling C1.
- Roast #337 = roast #54 in my 2020SR (the Australian model using 240v power - note that the 1lb button is now a 400g button). I used a 1P2B+++ setting and then, 30” after rolling C1, went manual with P2 + C + D.
- Roast #347 = roast #64 in my 2020SR. This was the first time I tried Andy Freeman’s KIS method, hence under the box it says “Let it roast and see what happens.”
- Note that roast #267 took 22’00”, roast #337 took 23’05”, while roast #347 (using the hotter KIS method) took only 17’50”.
