shot time: ~30 sec after appearance of espresso on bottom of basket
temperature range: 88C-95C (190F-203F) in increments of 1C
Protocol
Grinder: Robur with doser and (full) mini-hopper
Espresso machine: La Spaziale S1 V1, no preinfusion, brew pressure (no flow) 9.25bar, 53mm double basket, bottomless portafilter
Ground coffee into tared basket and adjusted dose to exactly 15.0g.
Very brief WDT stir with needle, then tamped to ~30#.
Pulled shots into prewarmed shot glass, stopping at ~35ml/30sec/blonding, then weighed resulting liquid.
Visually, all pours were good to excellent.
For tasting, poured shot into prewarmed cappuccino cup. Sampled straight, then with 1/2t sugar, then with increasing amounts (1-3oz) of microfoamed milk.
Tasting notes
95C
Surprising lack of bitterness.
Hints of fruit.
Decent with milk.
94C
More fruit.
Better with milk.
93C
Dark/bitter chocolate and some caramel.
92C
Slight ashiness (only taste defect I noted).
With sugar: dark/bitter chocolate, complex distillates, some caramel, slight nuttiness, little fruit.
Decent with milk.
91C
Ashiness is gone, fruit (green melon??) up.
Nice capp, slightly less intense flavors than 92C
90C
Slight ashiness emerging again in straight shots.
Nice fruitiness with sugar.
Slightly bland in milk, with caramel and butterscotch flavors.
89C
More ashiness in straight shots.
More fruitiness with sugar.
Slightly bland in milk, with caramel and butterscotch flavors.
88C
More ashiness in straight shots.
Even more fruitiness with sugar.
Still quite good in milk, with loads of caramel and butterscotch.
Conclusions
Ecco espresso makes good straight shots and short capps/macchiatos. A tantalizing fruitiness sets it apart from other "comfort food" espressos. Other flavors include dark chocolate at higher brew temps, and strong caramel in milk at lower temps. A slight ashiness is detectable in straight shots as a taste defect.
Best straight shots were at 92C (198F) on my LaSpaz, but there is more fruitiness and caramel at lower brew temps. A wide range of acceptable brew temps gives this blend a large "sweet spot" for espresso.
