Change of Coffee Grind Size
If your espresso tastes bitter, you may need to change the size of your grind. Here are the things you need to know:
- If the shot pulls its liquid too slowly or it tastes over-extracted, increase the grind size to improve it. This will allow the water to flow more easily between the grounds. Increase the size of the grind to pull the shot faster, this will give ease and less time to brew a shot.
- If the shot pulls its liquid too fast or tastes under-extracted, lessen the size of the grind. This will take a longer time for the liquid to flow between the grounds. The shots will cause to pull more slowly. The more water to pull, the shot is better and takes more extraction.
If these steps don’t take effect for the coffee to have a better taste, do this next step.
Le French Press
Fine, we don’t need the Franglais here, but still. THE French Press Method is about as simple as the AeroPress. Unfortunately, a French Press lacks the pressure necessary for a truly perfect shot espresso, but it will do in a pinch.
Start with a French Press, hot water (~200 degrees), and two tablespoons of ground coffee. After that, here are the complexities involved in making (sort of) espresso using Le French Press:
- Place the ground coffee into the French Press
- Add 2-3 oz of hot water over the grounds
- Stir this mix together for five seconds, making sure to use the French style of stirring
- Pour the rest of the water in and stir again
- Wait 4-5 minutes, depending on how tired you are
- Push the plunger down very slowly
- Drink immediately, depending on how tired you are
Voila, bon appetit, etc.
Adjust the Coffee Dose
One of the best ways to adjust the flavor of an espresso shot is by changing the coffee dose. It doesn’t need to have a perfect grind size. The final yield of your shot can be the best way of sorting out the flavor of espresso coffee.
- Look for the dose of espresso shot if too concentrated or if it tastes under-extracted. The longer time for a shot to pull the yield, it allows the water to contact the ground, this process will lead to more extraction.
- The final shot of espresso will also decrease its concentration. Make sure to reduce the final yield of your shot if your shot is weak or it tastes over-extracted
Cleaning is one of the most important. The old grounds and oils in the portafilter and group head will make a change on the aroma and flavor of the espresso. That is the reason why cleaning espresso machines every after use is essential to keep the taste, aroma, flavor, and texture of espresso fresh.
- Rinse the portafilter every after a single shot. Get the portafilter and make sure to remove the grounds by rinsing it from flowing water to remove any stuck specks of dirt and grounds.
- Cleaning all throughout the machine is essential. After used on a whole day, the pipes, as well as the entire system, must be cleaned.
Espresso coffee needs about 10 bars of pressure to remove all the oils inside the machine. The extraction of coffee oils is very important. The extraction temperature is another cost of the change in the taste of espresso. The extraction needs enough heat that requires about 94 degrees C. Adjust the broiler thermostat or give the espresso machine the right amount of temperature.
Hopefully, you now understand the various ways that espresso can taste bitter. The different factors affecting its substance and flavor play a significant role in the quality of the final product.
