Crema, The Unmistakable Sign
This thin golden layer on your espresso isn't just decorative. It's the barista's signature, proof that the beans are fresh and the extraction is perfect. At Carrera Café, it's consistently present.
See our espressoCrema is an emulsion of carbon dioxide, essential oils, and water that forms during espresso extraction under high pressure. When hot water passes through the coffee grounds at 9 bars of pressure, it releases the CO2 trapped in the roasted beans and emulsifies it with the aromatic oils of the coffee.
The result is this golden, dense, and persistent layer that floats on the espresso and concentrates a large part of its aromas. Crema is to espresso what the nose is to wine: the first aromatic impression, and often the most revealing.
A well-made crema is golden to hazelnut, uniform, with slight darker streaks on the surface. Too light: under-extracted, the coffee lacks intensity. Too dark, almost black: over-extracted, the coffee will be bitter and harsh. Golden: that's where you want to be.
The crema of a good espresso should last at least 60 seconds after extraction. If it disappears in a few seconds, the coffee lacks essential oils or the beans are too old. If it lasts several minutes, it's a sign of fresh beans, correct grinding, and controlled extraction.
Gently place the back of a spoon on the crema: it should sink slowly, without excessive resistance but also without collapsing. Crema that is too thick may indicate over-extraction. Crema that immediately gives way indicates a lack of pressure or too old beans.
The CO2 trapped in roasted beans gradually evaporates over time. Beans roasted more than four to six weeks ago have lost much of their CO2, and therefore their ability to produce beautiful crema. That's why serious specialty coffee shops work with recently roasted beans and use coffee within two to three weeks of roasting.
At Carrera, crema is a daily quality control indicator. Every morning, before opening, the barista pulls a test espresso and observes the crema: color, thickness, persistence. If something is wrong, the grind, pressure, or temperature is adjusted before serving the first customer.
It's this level of rigor that makes the difference between a good coffee and an exceptional coffee. And that's what you'll find in every cup at Carrera Café, in Petit-Champlain, Quebec.
When your espresso arrives, don't stir it right away. First, breathe in the aromas escaping from the crema: that's where the most volatile and delicate notes are concentrated. Then take the first sip through the crema. The second will be different. This is intentional.
Come judge the crema for yourself
Carrera Café's espresso speaks for itself. Come to Petit-Champlain and observe the crema: it will tell you everything you need to know about the quality of what you are about to drink.
