Starting the Machine
Before starting your lever coffee machine, make sure it is properly connected to a power source and that the water reservoir is filled with fresh, filtered water. It is important to use high-quality water to ensure the best flavor in your coffee.
Step 1: Power On
To power on the machine, locate the power switch usually located on the side or back of the machine. Flip the switch to the “On” position to start the machine.
Step 2: Preheating
Allow the machine to preheat for a few minutes. This will ensure that the water reaches the optimal temperature for brewing. Some machines have a preheating indicator light that will turn off when the machine is ready.
Step 3: Flush Group Head
Before using the machine for the first time or after a period of inactivity, it is important to flush the group head. This process removes any stale water or debris that may have accumulated. To flush the group head:
- Place an empty cup or container beneath the group head.
- Activate the brewing lever without placing any coffee in the portafilter. This will allow hot water to flow through the group head and into the cup, flushing out any impurities.
- Allow the hot water to run for a few seconds or until it appears clear and free from any debris.
- Dispose of the water and dry the cup or container.
Now your lever coffee machine is ready to use! Proceed to the next section for instructions on brewing the perfect cup of coffee.
Grinding and Measuring Coffee
To ensure the perfect cup of coffee, it’s important to grind and measure the coffee correctly. The grind size and the amount of coffee used can greatly impact the taste and quality of the final brew.
Coffee Grind Size
The grind size refers to how coarse or fine the coffee beans are ground. Different brewing methods require different grind sizes in order to extract the ideal flavors from the coffee beans.
For lever coffee machines, a medium to fine grind size is generally recommended. This allows for proper extraction without the risk of clogging the machine.
Measuring Coffee
Accurately measuring the coffee grounds is essential for consistent brews. Using too much or too little coffee can result in an imbalanced flavor.
A general rule of thumb is to use a ratio of 1:18, or 1 part coffee to 18 parts water, by weight. This means that for every gram of coffee, you should use 18 grams of water.
It’s recommended to use a digital scale to measure the coffee and water, as it provides the most accurate results. However, if you don’t have a scale, you can use measuring spoons. A standard tablespoon is approximately 7-8 grams of coffee.
| Amount | Ground Coffee | Water |
|---|---|---|
| 1 cup | 14 grams | 250 ml |
| 2 cups | 28 grams | 500 ml |
| 4 cups | 56 grams | 1 liter |
By following these guidelines for grinding and measuring coffee, you can enjoy a consistently delicious cup of coffee from your lever coffee machine.
Preparing the Portafilter
Before you can start brewing your perfect cup of coffee, you need to properly prepare the portafilter. The portafilter is the handle-like device that holds the coffee grounds and attaches to the espresso machine. Here are the steps to prepare the portafilter:
Step 1: Clean the Portafilter
Start by making sure that the portafilter is clean and free from any debris or leftover coffee grounds. Rinse it with warm water and use a brush to scrub any stubborn residue. It’s important to keep the portafilter clean to prevent any contamination of the coffee flavor.
Step 2: Insert the Filter Basket
Take the filter basket that corresponds to your desired brewing method and insert it into the portafilter. Make sure it is securely in place and that there are no gaps or loose parts. The filter basket is what will hold the coffee grounds during the brewing process.
Step 3: Weigh and Grind the Coffee
Weigh out the appropriate amount of coffee beans for your desired brew strength, usually around 18-20 grams. Grind the coffee beans to a fine consistency suitable for espresso. The grind size will affect the extraction and flavor of the coffee, so make sure to adjust it according to your preferences.
Step 4: Distribute and Tamp the Coffee
Evenly distribute the ground coffee into the filter basket. Use your finger or a distribution tool to spread it out and ensure an even extraction. Once the coffee is distributed, use a tamper to firmly press down the coffee grounds. Apply even pressure to create a level and compact puck.
Note: Tamping is an important step to ensure proper extraction. Apply enough pressure to compact the coffee grounds, but be careful not to over-tamp, as this can lead to uneven extraction.
Now your portafilter is prepared and ready to be attached to the espresso machine. Follow the manufacturer’s instructions to properly attach the portafilter and start brewing your delicious cup of espresso!
Extracting the Coffee
Once the lever coffee machine is properly serviced and ready for use, it’s time to start extracting the coffee. This process involves brewing the coffee grounds with hot water, allowing the delicious aromas and flavors to be released.
Here are the steps to follow for extracting the perfect cup of coffee:
- Start by filling the water reservoir with fresh, cold water. The water level should be below the maximum line indicated on the machine.
- Grind your coffee beans to the desired coarseness. For lever machines, a medium-fine grind generally works best.
- Measure the appropriate amount of coffee grounds based on your desired strength. Typically, a ratio of 1:18 coffee to water is recommended.
- Place the coffee grounds into the portafilter and distribute them evenly. Use a tamper to apply slight pressure, ensuring a compact and consistent bed of coffee.
