Taking you through the 2nd segment on how to use a commercial coffee maker. This time, you would be brewing coffee using the expresso styled way. Here are the detailed set of steps:
Fill water inside the café tank
You will have to fill in a sufficient amount of water inside the café tank. The quantity must be optimal in conjunction with the amount of coffee powder you would love to add. In case you are just the two of you, say you and your hubby, you need to add enough water to hold two tablespoons of freshly ground coffee powder. If you have guests coming over, you can add five to six tablespoons of granular or grounded coffee powder. Then you will have to add water accordingly. The reservoir is usually located on the side or back of the machine.
Use tepid water
The water must not be too hot. You can use normal tepid water or cool condensed or purified water. This is mainly because you don’t want calcium carbonates, limestone or mineral build up on your café machine.
Warm up the machine
You want the aroma or the taste of the café to be irresistible, isn’t it? Then you should allow the machine to warm up. Allow at least 15 to 45 minutes for the commercial coffee machine to warm up. Some varieties come to you with a temperature alert. Once it turns red, it simply means that the café machine is just at or above the brewing temperature. Now if you pour water, it will heat up and you will arrive at the most required temperature to force hot water through the coffee grounds.
Grind the coffee beans
If you want the perfectly brewed latte or expresso, then it is ideal that you grind coffee seeds all by yourself. As you are already into the commercial space, you know how much your customers crave over a freshly brewed cup of espresso café. Keeping this in mind, you can grind the beans every time you want to brew an espresso. You can use a burr grinder instead of a blade one. Then, you will have the beans ground with a uniform consistency.
Apply pressure while you add the pounded coffee powder
To force the pressure down the café machine, you will have to know the knack on how it is being done. You will have to get a portafilter rotated. A portafilter is a small metallic dish that has a long handle. This can eventually be attached to the commercial coffee machine. The filter screen in the portafilter is called the basket.
The portafilter now fills the grinder chute and the café basket is filled in, evenly. Once you fill the portafilter with the pounded coffee grounds, you use your clean forefingers to achieve a uniform level on the casket.
Now, use a tamper. Have you been wondering what a tamper is all about? Well, it is a flat metal disk with a rubber handle. This equipment makes the coffee seeds fit compactly into the portafilter. You will have to achieve a pressure of 14 kg or 30 pounds for the perfect consistency.
Allow the machine to brew
Now plug the coffee machine into the power-plug socket to brew the requisite amount of expresso. The more pressure you apply through hot water, you get the expresso in a consistent quantity and a fabulous quality. You need to practice sessions with respect to how to use a commercial coffee maker.
Boil milk to mix with the expresso
Your expresso is now all ready for use. You can boil milk in the coffee tank. You must have used the reservoir to fill water at the initial stage. You can drip dry or clean up the tank to boil or skim the required amount of milk. Add the expresso to the milk. You can serve the piping hot expresso with cookies or fresh fruit cakes. Voila! You are all set to enjoy home-made or commercially prepared expresso café the style you always wanted to.
These steps give you end to end procedures on how to brew coffee using a commercially acclaimed coffee maker.
