Roast Defect

[seboissa]

Hi,

I have and love the nano7. Usually I use profiles from the community but this time I set one up (without an idea else then 7 videos on youtube, I love trying things just like that).

However I got roast defects. Those I get almost always when I roast darker than 2.2. I do get them with all profiles, but with mine at 3.9 it was soo much that I thought this is a good time to ask the community.

How is it that I have those so often? Can I do something against that (not just in my profile)?
Do they really change the taste (I habe the feeling it is a massive drop in quality when I leave those beans in)?

thanks
Sebastian

Hi Sebastian

Thank you for the message.

What origin is this? Can you please send a log of the profile? On taste, they can effect taste. Just depends on how much are in the batch.

The defect is generally caused from too high charge or too much intense conduction energy being applied on the coffee- Often from the chamber or in air roastings case, air or fan flow too slow.

Hi Wayne,

so these defects show up in all roasts that are higher than 3.5. I took one where I remember that I had around 7% defects.

thanks for checking

Good day Sebolssa

I hope you are well.

Is this just with the Colombian or other coffees?

Could you try the same profile with the same level on another coffee. I feel that defect may be coming at the end of the roast at that high level with the coffee. 233 degree may be a Bit too intense from a roast on the beans .
