How to Make a Perfect Coffee

Start with fresh beans, correct dose, proper grind size, and consistent extraction pressure.

Espresso Basics
Gemilai espresso machine beginner guide
Fresh beans: use beans roasted within the last three months for better aroma.
Fresh grind: grind right before brewing to preserve flavor and reduce unwanted odors.
Proper grind: too fine can over-extract, too coarse can under-extract.
Good storage: seal beans well and keep them away from humidity and direct sunlight.

Use these settings as a starting point. Pressure and timing can change based on roast level, freshness, basket size, and grinder setting.

Extraction Time25 +/- 5s

A 58mm commercial filter basket and professional shower screen are compatible with many baskets on the market. They help support fine crema, stable extraction, and a more cafe-style shot at home.

  1. The filter chip may be clogged. Remove it and clean the holes at the bottom of the filter screen with a brush or pin.
  2. The coffee powder may be too fine. Try a coarser grind.

Brewing Tutorial

Troubleshoot fast flow, pressure gauge movement, puck preparation, and grind adjustment.

  1. Grind is too coarse. Adjust to a finer grind.
  2. There is too little coffee. Increase the dose so the grounds sit near the groove line of the filter basket after tamping.
  3. Coffee is not tamped. Distribute evenly and apply firm, even pressure.
  4. Beans or powder are stale. Use fresh coffee, ideally within 1 week to 1 month for optimal extraction.
  1. Test the machine with the cleaning pad. If pressure is above 9 bar, the machine pressure is normal.
  2. If pressure is normal, grind the beans finer. The ground coffee in the portafilter should sit near the groove line.

Steaming Tutorial

Improve milk texture, steam pressure, preheating, and wand maintenance.

Milk Frothing
Gemilai espresso machine cleaning and maintenance guide
  1. The container is too big or the milk amount is too low. Use a smaller milk pitcher or add more milk.
  2. The milk temperature is too high. Use refrigerated milk.
  3. Skim milk is being used. Use cold whole milk for richer foam.
  4. The steam wand nozzle is clogged. Clean deposits in the nozzle with a needle.
  5. For G3005E, G3005H, and G3006 models: press the steam button and wait for the indicator to stop flashing.
  1. Make sure the machine is fully preheated. Buttons and display should stop flashing, and the temperature should reach the preset value.
  2. Before first steaming after preheat, drain condensed water from the internal water circuit for about 30 seconds to 1 minute. Once drier steam appears, use it normally.
  3. Use cold whole milk, a 15 oz frothing pitcher, and fill the pitcher to about half a cup.

Usage Tips

Set up a new machine correctly and keep your espresso routine consistent.

First Use

Follow the “Before First Use” steps in the manual.

  • Take out the machine and all accessories, then check the manual to make sure nothing is missing.
  • Install the water tank and drip tray if needed. Make sure the water tank is securely in place.
  • Plug in the power fully, turn on the machine, and wait for preheating. Press the extraction button to clean the internal water path.
  • Press the steam button, wait for preheating, then release steam briefly to clean the inside of the steam pipe.
  • Make two cups of coffee and discard them. This helps remove any new-machine metallic taste before normal use.

  1. Select fresh beans, generally roasted within three months.
  2. Grind immediately before brewing for better flavor.
  3. Adjust grind size carefully. Too fine can over-extract, while too coarse can under-extract.
  4. Seal remaining beans and avoid humidity or direct sunlight.
