In the article “Latte Art, a new twist on coffee” posted on the website http://wayofcoffee.com/index.php/2010/10/18/article-latte-art-a-new-twist-on-coffee/, there is some very good information about latte art, which is becoming popular more and more popular in the coffee business nowadays.
The name “latte art” was taken from Italian word “latte” - milk, and it is the art on coffee created by milk. A barista making the coffee should be very well skilled to introduce people to good coffee and beautiful latte art.
There are many ways to make a beautiful design on a cup of coffee, but first the components of a drink should be made correctly. A shot of espresso should be pulled (like all baristas say) correctly to avoid bitter or sour taste of coffee. It has to be a concentrated shot of espresso about 25-30ml for 25-30 seconds. A barista also should know how to get the necessary texture using milk, so it would be good to make a design. To do that, he or she needs to find a moment when the milk is saturated enough with oxygen by using the wand on the machine and to find the moment when it spins breaking bubbles. One more very important moment here is not to overheat the milk, so that won't get a little bitter taste and bubbles too.
The most difficult process is starting when the espresso and milk are ready. The barista pours the steamed milk into an espresso to make a design. Making design, it is important to move hands correctly, which takes a lot of time to practice. But once you get the idea of how the process works you will get beautiful rosettas (leaves), hearts and everything else that your imagination wants to express.
I could do a lot of different designs on latte and recommend that you try it. It is fun to create something pretty and to make your family and friends smile.
