I’m starting to think it’s the beans.

Gifted beans that a family member swears by, and I keep getting sour, thin, under-extracted shots that just pour out.

Breville Dual Boiler, Breville Dose Control grinder, Pullman basket. I can typically get a good shot with 18g ground to setting 12 at 93°, with 8 seconds of preinfusion, and get about 40g out in 30 seconds.

I’ve gotten up to 22g at setting 2 at 95° with 10 seconds of preinfusion is still giving me 50 to 60g of sour espresso in 15 seconds. (Before you say grind finer, the burrs zero at setting 1.)

Any recommendations before I toss the bag and go back to my usual beans?
