I’ve been using James Hoffman’s recipe since I bought AeroPress, and I was pretty satisfied. While being simple, it produced rich, balanced cups of coffee for both light and medium roasts. I was happy with it. But then I started noticing that some light-roasted coffee was too bitter. It rarely happened, but when it did, it wasn’t possible to get rid of that excessive bitterness. When I tried to increase the grind size, I got watery, but still too bitter coffee. At first, I thought there was something wrong with the coffee beans, but then I thought, maybe immersion brewing was just not suitable for them. So, I decided to find another recipe.
