It’s all about saturation.
The longer water is in contact with coffee, the more is extracted. Finer grounds equal more surface area to extract from.
…The hotter the water, the more extraction. But TOO much extraction leads to bitterness…
Things will be less bitter if you take control of these things.
That means if you can’t stand the heat- then coarsen up. Or spend less time together…
The opposite if this is insipidness. Your coffee doesn’t want that either. You want a nice relationship with your coffee; you want great body in the morning… a nice mouthfeel, …and rich is good too… Right??
If THIS is what you want to wake up with, then you NEED to listen to your coffee. Your coffee WANTS to be awesome for you. Listen to it. It’s saying to you let’s go somewhere… GO there. Your coffee loves you. It’s telling you to…
Adjust your grind, go hotter or cooler accordingly. Spend quality time together…
Do these things.
And surprise your coffee with some roses sometimes too, just because.
