Hi, guys! Few days ago, one of my friends asking me a question when we are ordering coffee in a coffee shop. His question was, “what is espresso crema and what a relationship with espresso coffee?”
Yah! There’s an intimate relationship between espresso crème and a perfect shot of Espresso. But before we know the relationship between them, we need to know what espresso coffee is and how it prepares?
Do you remember? At coffee shop when we want a strong coffee, the common question comes from the sales assistants – Do you want Espresso?
Here I described it part by part for you guys.
So, actually, what is an Espresso shot?
Espresso is a thick liquid extraction related to a coffee brewing method. Basically, it is an Italian origin authentic coffee.
Espresso is a strong black coffee brewed nearly boiled (91° to 95°C) forced stream water that goes through the subtle (50gm±10gm) compacted ground coffee. To brew one-shot (1.5Oz) of Espresso, take 30 seconds extensions by using a quality espresso coffee maker. Actually, an excellent shot of Espresso follows this sequence 9-7-30-30. It also says, “Espresso Golden Rule.”
I recommend, to get the best coffee crema, you should use a coffee maker that is brewed in an automatic process.
Now, let’s know what espresso crema is?
A crema signifies a layer of beautiful foam bubble creates on the top of an espresso shot. Standardly, it looks like the yellowish-brown or brown-gold colour. These colours depend on the roasting and brewing methods of espresso coffee.
Where intimate relations of espresso coffee and crema?
Indeed, the taste of Espresso doesn’t depend on the thickness or colours of crema. Usually, it is the indicator of the quality of your espresso shots.
That means the quality of the Espresso determines by the level of its cream. It helps to find out the best beans for espresso crema.
What represents the relation between Espresso Crème and Carbon Dioxide?
Currently, we know the espresso crème is a nice foaming layer on the surface of the espresso coffee. Typically, this layer depends on the freshly roasted beans.
Freshly roasted beans refer to those beans which have rich absorption of carbon dioxide/CO2.
In the brewing time of Espresso, while the pressurized water is coming through the tight-packed finely ground coffee, that time this carbon dioxide also goes out and creating the foam bubble.
My friends, now we know that a good espresso shot can make excellent coffee foam.
So, let’s scrutinize how to make perfect shots of Espresso. Only then will we get our expected coffee foam on the top of the coffee.
How do you make excellent shots of Espresso?
When you prepare great shots of Espresso, the crème is naturally produced. So, when you get a layer like cream of cake on your coffee, then you confirm that a perfect shot of espresso coffee brewing method is complete.

Crush your freshly roasted coffee beans as per your cups quantity by your Grinder before preparing Espresso. Because of doing this, you get fresh, bold taste and fragrance and crema from your coffee.
Put 1 shot (7gm) or double shots (15gm) of refined ground coffee in the portafilter. Press evenly by a temper to make sure it’s sufficiently compact before positioned the portafilter in your espresso machine.
After placing the portafilter in your espresso machine brew head and placed your preheated espresso cup beneath it.
Press the power button and wait for the 9bar pressure boiled water come through the portafilter and stored the 30ml of coffee extract in the cup.
The ideal extraction time of an espresso shot is 25 to 30 seconds. Within a few second crema should form after the brewing process starts.
