Tandem Roasters
Grind: #17-19 espresso
Preheating the portafilter now. This is changing how my shots are pulled.
18g in 38g out for 37 seconds. Grind was 15. Very dry puck. Result was very bitter.
New grind is 16 but the shot pulled at 46 seconds. Came out bitter as expected. The preheated porta is really changing how I pull shots for myself. Next will be 18. Never thought I would go that high.
17 grind pulled 30 seconds at 48g.
19 grind size pulled 36 grams at 25 seconds. Good.
