1.7 flow rate, 12 grind

Much fuller mouthfeel but more astringency.

Learnings here – lower flow rate leads to more mouthfeel, a thicker coffee. Up to a point. If it’s too low for the bean you end up with astringency – you can taste both bitter and sour.

Higher flow rate leads to less mouthfeel, more acidity, but the acidity can be muted and smooth, you just feel it sticking to the top of your mouth. But the cup feels a lot more watery.

For me, I think I want the lowest flow rate that doesn’t introduce astringency.

I will say the higher flow rate tasted better in an Americano.
