Your coffee just arrived, roasted yesterday. You brew it right away and the cup tastes sharp, thin, hollow. The problem isn't your technique. Freshly roasted coffee holds up to 10 bars of CO2 pressure that physically repels water during extraction.

The word "anaerobic" shows up on more coffee bags every year, but this word only tells you that the coffee was fermented in a sealed container. It doesn't tell you which microbes did the work, for how long, or at what temperature, or how any of it shows up in the cup.
A coffee's genetics, growing conditions, fermentation parameters, drying protocol, and roast development all shape what you taste. The fermentation method is just one variable among many.
