I also bought some Leam Hammer with the recent Black Friday deal. Pulled a couple shots this morning. Opening the bag my first impression was this is a darker roast than I was expecting. Certainly not what I consider light from a visual perspective. Here it is next to a light roast from Slate for comparison.
I pulled two shots. 14.5 g in and 30g our for both. 20 second of active preinfusion starting at .5 bar and increasing to 3 bar until the puck is saturated and then did quick ramp up to 8 bar for extraction. First shot was pulled at 201F and second at 199F.
Both shots were similar. They pulled with a fair bit of crema and on the slightly thick side. I'd say the tasting notes on the bag were on point. A mix of fruits, florals, and a bit of milk chocolate. I wasn't getting a ton of clarity, though. Individual flavors seemed muted and there was a bit of dull acidity there. Not biting, but not playing well with the overall flavors, either. The espresso was relatively tasty all the same, but a little boring. I'm definitely not satisfied.
I'll try again tomorrow and will maybe loosen up the grind and dial back the preinfusion. I wonder if perhaps this is a bit too dark for the long drawn out PI.
