You can create coffee that is balanced to your taste by controlling the extraction.
How do you improve coffee extraction?
finer grind Grinding finer increases extraction. As you grind finer it will easier to extract but also you will increase the brew time at the same time which will also increase extraction. The more water and coffee spend time together, the more coffee will give for itself to the water.
How do you adjust the extraction time?

Increase the wet dose if your shot is too concentrated or if it tastes under extracted By letting the shot pull longer to increase the yield, you allow the grounds and water to be in contact for longer, which leads to more extraction. Adding 2-4 grams of yield is enough to make a very noticeable difference taste-wise.

What is the best temperature for coffee brewing?
Your brewer should maintain a water temperature between 195 to 205 degrees Fahrenheit for optimal extraction. Colder water will result in flat, under-extracted coffee, while water that is too hot will also cause a loss of quality in the taste of the coffee.
How long should a single shot of espresso take to extract?
ideally you are looking for an extraction time between 25 and 30 seconds “If the espresso extraction time is seconds your grind is too coarse.. you should adjust your grinder to a finer setting.” “If the espresso extraction time is >30 seconds your grind is too fine..
