Your morning espresso is made up of about 90% water. A typical cup of black coffee brewed in a funnel or aeropress has as much as 98-99% water!
It's no secret that water plays one of the main roles in the preparation of coffee. Its quality and mineral composition directly affect the flavor, so our team recommends adhering to the following parameters:
The aroma of the water is clean, fresh, and fragrance free
The color is clear, transparent
Chlorides - 0 mg/l
Mineralization - for espresso: 150 mg/l (75-250 is acceptable), for filter coffee: 50-70 mg/l (10-100 is acceptable)
pH - 6,5-7,0 (as close as possible)
Calcium hardness - 50-175 mg/l
Calcium alkalinity - 40-75 mg/l
Iron - 0
Manganese - 0
Copper - 0
Sodium - maximum 10 mg/l
You can see the mineralization on the label of a bottle of water in the supermarket, and you can check the mineralization of water from the tap or after a home filter with a TDS water tester, which can be purchased at any popular online store.

factors affecting the flavor of espresso:
Amount of coffee: When selecting the dosage for brewing, always refer to how many grams the portafilter basket is designed for (most often 17-18 grams). Do not change and control the amount of coffee from batch to batch so that the coffee flavor is consistent.
Brewing ratio: This is the ratio of the weight of ground coffee to the weight of the finished beverage. The amount of water used for preparation will affect the flavor of the coffee and its concentration. The following ratio can serve as a starting point: for 1g of coffee, 2g - 2.2g of water. Example: 18g of coffee with a beverage yield of 36g - 40g.
Grind and brewing time: These two factors are interrelated. How fine or coarse a grind you use will determine the brewing time. Adjust the grind so that the brewing time is between 20 and 30 seconds.
Water temperature:
The standard temperature for espresso is 93.6 degrees. Permissible limits: 90.5 to 96 degrees.
Time from grinding to brewing: up to 1 minute, because every second the flavor and aroma substances that make coffee delicious evaporate from the ground coffee.
