Roasted this blend once again: 50% Brazil BSCA 30% Sumatra Aceh Wet Hulled Gr1 20% Ethiopian Ghimbi. Green Bean blend. Ended up being darker (translates to got distracted, so ended up with a darker roast). :-[ I still get a bit of an earthy taste from this Sumatran. Not a bean that I like. Espresso is still ok, but could be better. Tried a variation and got the perfect result. 50% Brazil BSCA 30% Sumatra Panjang Mandheling 20% Ethiopian Trabocca Harrar Green bean blend. A delicious, well balanced espresso. Lots of sweetness, body and some fruit. Very, very happy with this result. Roast profile changed slightly. Shorter time between first and second crack. First crack starting at 9 minutes, Roast Stopped at 13:30 minutes. Second crack was beginning and the beans were emitting a few snaps like rice bubbles when tipped. FZ-RR roaster. BPI blend: 35g Brazil Daterra Sweet Collection 65g Brazil Fazenda Lambari Estate 65g PNG Waghi AA 45g Indian Monsooned Malabar AA Green bean blend. FZ-RR roaster. This produces a very smooth espresso, lots of body and a nice cocoa finish. Tons of crema, with gloopy pours. Very pleasant as espresso or in milk. I like this blend also. Might try adding another bean to this blend, and reducing the Brazil a bit. Not sure what to add, open to suggestions.
