The 5 Golden Rules
Use Only Fresh Beans
The Fresher the coffee beans are, the better crema you will get; the older the beans are, the more time they have had to oxidize, which will damage the beans.
Use the Best Espresso Machine
With brewisto, a water pressure of at least 9 bar can be produced with each pressing, assisting by water temperatures as high as 90C to 100C. Sure, by using brewisto as your coffee maker, brewing a perfect crema coffee is not a problem.
Don’t Forget to Tamp!
Brewisto has prepared a spoon for you to tamp your coffee in a more effective way. After insert coffee powder to the powder filter, use the bottom of the spoon to tamp the coffee. Trust me, a good tamping will significant affect the result of your coffee.
Get Your Grind On
The grind of your coffee and the above tamp go hand-in-hand, get one of these two wrong, and your crema could suffer as a result. Getting your grind correct is key to making the best crema.
Fresh Water Only
And lastly, the water might be pretty obvious to some, but I should still reiterate the need for good clean filtered water. Please don’t use tap water, if you do, all of the above will be a waste, and the chances of getting a good crema will be dramatically reduced. Making crema relies on all of the above steps, and using the freshest, cleanest water plays a significant role in achieving that. After all, espresso is 97-98%!
How to tell a Good Crema and Bad Crema?
The best espresso crema consists of tiny carbon dioxide bubbles inside a film of sugars, oils, and fats.
The crema should have dark-brown to hazel-brown foam with tawny reflexes throughout combined with a very subtle texture.
To tell a good espresso crema from the bad is pretty simple, tilt your espresso cup to roughly a 45 degrees angle.
The crema on top should stretch to cover the surface and then re-form as an even layer when the cup is set right. A good crema should be an even layer of fine bubbles that is ever-so-slightly ”elastic, ” and it should hold.
An espresso crema is that golden fatty froth that graces the surface of any well-made shot of espresso. It looks great, plus you’ll also get a better aroma, fuller flavor, and overall better mouthfeel from your shot of espresso.
