The Kaffelogic 12 core profiles

#1243

Post by kaffelogic »

The Kaffelogic benchtop roaster is a profile roaster. You get different results by using different profiles.

The default profile is built-in. It will make delicious freshly roasted coffee from just about any green coffee beans. It is called ‘K-logic classic’.

However, even better results can be achieved by selecting one of our 12 core profiles to suit the coffee you are roasting.

These profiles have been developed by coffee specialist Wayne Burrows. Wayne is former all Africa barista champion, and has 15 years experience roasting coffee professionally. Wayne joined the Kaffelogic team early in 2020 and developed these profiles to give Kaffelogic users an easy way to get the best out of coffee from all over the world.

Hello Team Kaffelogic,

Thanks for the profiles.
Could you give an explanation as to the difference seen in the various profiles.

What are you trying to achieve in the cup specifically with a more powerful start on one profile compared to a much more extended roast on a different one? Body, sweetness, acidity etc.?

Why for example does the profile vor 1500-2000 Rest move along faster in the roast than the 2000-2700 Rest profile from minute 2:00 on?

I understand the need to roast differently for beans of different density (or moisture content, or size, or age etc.), but this is the first time I've heard of the possibility to alter the RTDness of a roast through the roasting profile. Would love to hear a (scientific) explanation for your ideas here.

Cheers,
Litosh

During roasting and after roasting the chemical composition of coffee changes. The point of peak flavour is effectively the point where the ratios of flavour-producing chemicals are at an organoleptic optimum. While conventionally roasting is carried out in such a way that this peak is reached at 3-5 days post roast, it is, within obvious limits, possible to arrange for the peak to occur at any time. This is done by manipulating the rate of different chemical processes during the roast, something that in a profile roaster is done by manipulating the profile.

The general principles can be understood from Nicoli and Savonitti in Chaper 6, Espresso Coffee: The Science of Quality, Illy and Viani, Elsevier, 2nd Edition, 2005. Of particular interest is Figure 6.8 (page 242) which shows clearly how the ratio of different volatiles changes over time.

Are there any changes in the latest download of the core profiles? They are now called "Finished Profiles" and don't have the V1 suffix.

Wayne,

The document Map of coffee growing countries of the world is a wonderful reference.

If you add Cuba, Australia, Venezuela, Vietnam, the Philippines, Dominican Republic, Bolivia and Timor to the list, it will be even better.

Hi guys,

It looks like someone has put a lot of work into coming up with these profiles; I've got the KL back from my friend and I'm looking forward to tasting my way through these. Ahead of that, I want to get a sense of what your expectations of the different roast levels are.

I'm looking at trying cupping and filter roasts. Could you let me know what sort of roasting weight loss I should be expecting from these. I'd like to be able to work out if my KL is hitting the mark, or if there is something wrong with it. When you guys say a cupping roast, is that intended to be a SCA standard cupping roast?

I'm using a fresh crop Guatemalan caturra, if that makes a difference to you.

Cheers,
Luca

Hi Luca

darryl here ( definitely not a KL expert). I have found on a range of roasts (from 3-4+ roast level) 16 % is about standard. Caveat - I use inexpensive scales and the small batch sizes and rounding make that figure a bit rubbery. I measured and compared to a number of other roasts from a different roaster just to see if fluid air roasting profiles could be compared to Behmor profiles, and when my results were similar i became less fussy with weighing.

I look forward to comments arising from your trained palate.

Hi Luca

I’ve had some good results with a range of beans for light roasts at around 1.2-1.5 with the core profiles, and about 1.8 if I intend on using the coffee with milk. 1.8 is about 20% DTR on my KL when using the core profiles. I tend to find higher levels are needed on the 0-1200m profile because the profile is slower (1.8 on that profile is seems lighter than the 1.8 on the higher altitude profiles). I predominately drink espresso and am aiming for origin flavours without adding ‘roastiness’ or defects.

I haven’t played with roasting for filter as much as I would like to yet, and am not yet 100% happy with any of the profiles I’ve tried for pour over. The core profiles have not tended to have as much clarity in the cup as I am looking for in a pour over. I am still experimenting with levels and profiles for that purpose.

Not sure how much that helps, but that’s my 2 cents! :D

Look forward to hearing what you think of the core profiles.

Cheers,
Matt
