Quite possibly.
I’d say it’s just how I like it 80% of the time, and amazing 10% and terrible 10% of the time.
My go to is Yirgachefe.
Every so often I buy beans to see what I’m missing and I’m usually very underwhelmed. It’s time I did this again.
New Zealand is lucky as the importers don’t bring in much crap coffee and so the average is good. A large bulk is brought in by just a couple of companies and all seem to have high standards.
The key to home roasting for me is freshness. I like coffee a couple of days after it’s roasted. I can control this and struggled when I was buying beans.
Both of these things are surprisingly difficult to do properly, with enough consistency and control. I believe temperature profile can noticeably affect the roast, and being able to consistently hit a profile (and thus experiment and improve) is really difficult with something like a heat gun.
I did the heat gun thing for a while, and the air popper thing for a while, and even modified the air popper to be able to control fan speed and heating element separately. I got good results but hit a wall and needed more control. I started building an Arduino-controlled air popper to be able to get more consistent results, then decided brewing top-quality coffee coffee was challenging enough when roast quality was delegated to experts. Since then, I've been buying from local roasters.
