Common mistakes when creating coffee foam

Use coffee without the highest freshness

You should plan to use certain coffee beans. Use all the coffee in one bag one at a time and then open a new one. Avoid opening many bags of coffee at the same time to store in a box for the sake of convenience, but in fact, it is a serious mistake.

Coffee beans are only freshest for 4-10 days if stored properly. You should store coffee in sealed containers in a shady place, away from direct sunlight, and do not put it in the refrigerator or areas with high humidity.

Do not use electronic scales in coffee making

96% of baristas often measure coffee with their eyes, and this is not recommended. Learn how to measure coffee with a dedicated electronic scale. If you can use 20g of coffee to make 30ml of espresso – instead of more than 20g, then you have saved a lot of coffee powder. Remember, you are not only making one cup but many cups. So don’t waste it.

Use hard or untreated water

An espresso is 98% water and 2% coffee. But unfortunately, a few people don’t care about water treatment. Use purified water or equip a dedicated water filter coffee machine.

Don’t carelessly use tap water, and then google how to descale your coffee machine. By then, you’ve made terrible espressos. Every 3 – 6 months, check the water you use and clean the machine and pipes.

Do not clean the coffee machine

Don’t open your coffee maker one day and burn it because everything inside is dirty. Residues, stains, rust, rancid odors accumulate throughout the machine and dispensing equipment.

Using the wrong type of milk in coffee

Any barista knows that the milk used to make cappuccino or latte drinks is pasteurized milk. This is high-protein milk, and this will give you the best frothing and steaming.

Using pasteurized milk, condensed milk only works to help you get used to the skill of milking. Using cheaper ingredients for practice is a good idea, but it will never help you make a standard Italian cappuccino.

Do not check the coffee preparation temperature

It is necessary to check the brewing temperature before making espresso. The brewing temperature is stable at 92°C. This test step is very important, but few people do it, so make it a habit. A stable dispensing temperature will give a stable extraction temperature.

And that is the necessary condition besides the pressure factor for you to make the perfect cup of espresso.

Do not flush the group-head before and after extraction

Surely new baristas will not be familiar with this operation. But flushing before extraction is very important and cannot be ignored. Doing this helps remove the coffee residue, making the espresso always fuller of flavor, and the temperature is always stable.

After extraction, drain the group-head and, steam the steam hose and pull it back to its original position. As well as always put the handle in the group-head. It shows your professionalism and helps to remove the stagnation of milk and coffee residues inside.
