Ethiopian Kaffa Anderacha. 100g for 9m20s at 65%. Cracking started at around minute 6. When I was happy, I went to shake it outside in the sieve. I was aiming at a light roast but realizing that it's not a very even method, I went and made sure even the greener beans had time to get a little tan. I think I'll use 50g instead next time.
Advice is super welcome.
I just prepared a cup using the James Hoffman daily driver aeropress recipe as soon as it was cool. I know I should let it degas but I wanted to experience the freshest cup possible as a base for later comparison. As is, to my understanding, it tastes planty, caramely and neither too acidic, astringent or bitter. Really nice cup.
I've done some roasting in a cast iron, more for the fun of it since it was really difficult to nail. But I remember it taking way longer, at least 15 minutes for first crack/light roast. Stirring constantly for 15 minutes was not the most thrilling thing... It was still uneven but not as much as it looks in your picture. Maybe turn down the heat a bit.
And yeah I agree, the drastic change in taste from freshly roasted to a week old was surprising.
