Step 5: Mastering the Brew: A Guide to Perfect Your Coffee Brewing Technique

Congratulations on making it this far in your home barista journey! You’ve familiarized yourself with coffee types, selected your beans, learned about proper storage, and equipped your kitchen with the right tools. Now comes the exciting part: brewing your first cup of coffee. In this guide, we’ll cover the essential techniques to make a perfect brew, including the vital role of water pressure.

Water Quality, Temperature, and Pressure

Water makes up about 98% of your cup of coffee, so its quality, temperature, and pressure directly impact your brew.

Water Quality: Filtered or bottled water can often yield better results than tap water.

Water Temperature: The ideal brewing temperature for coffee is between 195-205 degrees Fahrenheit (90-96 degrees Celsius).

Water Pressure: This is particularly relevant if you’re using an espresso machine. The pressure of the water when it meets the coffee grounds can have a big effect on the final outcome. The ideal pressure for brewing espresso is usually around 9 bar during extraction, though this can vary depending on the machine and personal preference.

Coffee-to-Water Ratio

A general rule of thumb is to use 1 to 2 tablespoons of coffee for every six ounces of water, but this can be adjusted to taste. More coffee will result in a stronger brew, while less coffee will result in a weaker one.

Grinding Coffee Beans

As mentioned in step 4, the size of your coffee grounds should align with your brewing method. As a general rule, the longer the water and coffee are in contact, the coarser the grind should be.

Coarse Grind: French Press, Cold Brew

Medium Grind: Drip Coffee Makers

Fine Grind: Espresso Machine, Aeropress (short brew time)

Extra Fine Grind: Turkish Coffee

Brewing Method

The brewing method you choose will significantly affect your coffee’s flavor and body. Here’s a basic rundown of the techniques for the most common brewing methods:

Pour-Over/Drip: Wet the grounds with a little water and let them “bloom” for about 30 seconds before slowly pouring the rest of the water over the coffee.

French Press: Add your coffee grounds to the press, pour in hot water, give it a gentle stir, and let it steep for about 4 minutes before plunging.

Espresso Machine: Pack your coffee grounds into the portafilter. The coffee should be packed well enough that the hot water passes through the coffee at the correct pace. Ensure that your machine is set to the correct pressure for your desired extraction.

Tasting Your Coffee

After brewing, take a moment to taste your coffee. It’s a good practice to understand the flavors you can extract from the beans. If the coffee tastes too bitter, it may be over-extracted, and you can try a coarser grind or brewing for less time. If it’s too sour or weak, it may be under-extracted, and you can try a finer grind or brewing for longer.


Mastering the brew is a combination of science and art. By understanding and controlling each variable, including water pressure in espresso brewing, you can experiment and adjust your method until you find that perfect cup that suits your taste.
