A Gentle, Flat 2.5ml/second. Continuing our weekly take on the same beans, same machine, but different pressure profile, we find ourselves looking into yet another gentle pressure profile.This time, it’s the “gentle flat 2.5ml/second” profile which is part of our DE1PRO decent espresso machine’s pressure profiles. According to the description, this profile was created by Adrien Sénac of Cafeism. He’s a french barista, and he designed this profile to create great and consistent shots from lightly roasted coffee beans that are very aromatic.
With 18.0 grams of coffee in, the profile starts extraction with a low-pressure preinfusion for 9 seconds at a pressure that directly goes to 6 bar and stays at that pressure level throughout the course of the brew, for a pouring time of 44 seconds at a low temperature of 91.1°C. The total weight of the espresso after extraction was at 40 ml.
Using our house blend, DC7 (comprised of Guatemala Huehuetenango, Colombian Supremo, and Northern Philippines coffees) our shot produced an aroma that had a hint of cacao and spices, with notes of nutmeg followed by a subtle nutty flavor, with very low acidity. The body left a smooth mouthfeel but it lacked balance. The “gentle flat 2.5ml/second” pressure profile was smooth and sweet but did not make for an exciting flavor.
Here’s the numerical breakdown on a 1-10 scale:
Aroma: 7.5
Flavor: 8
Finish: 8
Aftertaste: 7
Acidity: 7
Body/Texture:
Balance: 7
Sweetness: 7.5
