“15-16%: This is the “little hump”.
I’ve often found these extractions
to be cirtusy and juicy, with a more
delicate acidity than that of higher
extractions. To me they’re the
coffee equivalent of Beaujolais

“16-18% is a bit of a dead zone: less
fruit than either hump, and acidity
tends to be flatter. The caramel
content of the cup may be higher
than at the little hump, but the
overall cup is rarely great. Woody
and harder flavors often come to the
fore at this range.”
