How to Use the Lelit Bianca for Espresso: A Step-by-Step Guide

The Lelit Bianca is a dual-boiler espresso machine that has earned a cult following among home baristas. Its standout feature is the manual pressure profiling paddle, which lets you control the pressure during extraction. This guide walks you through every step—from unboxing to dialing in—so you can pull cafe-quality shots at home.

Whether you're new to the Bianca or looking to refine your technique, this article covers the essentials: water preparation, grinder settings, temperature control, and advanced profiling. By the end, you'll be confident in using the Bianca's unique capabilities to highlight the best in your coffee beans.

1. Unboxing and Initial Setup

When your Lelit Bianca arrives, take time to unbox carefully. Inside you'll find the machine, a water tank, portafilters (both spouted and bottomless), a tamper, and a cleaning kit. Remove all packaging and place the machine on a stable, level surface near a power outlet and water source. Ensure the water tank is seated properly and filled with fresh, filtered water.

Before first use, prime the boiler by running water through the steam wand and group head without coffee. This flushes out any manufacturing residues. Then, set the machine to your desired temperature. The Bianca has a PID controller that lets you adjust brew temperature in 1°C increments. For most coffees, start with 93°C and adjust based on taste.

• Fill the water tank with filtered water for best taste.
• Prime the boilers before first use to clean the system.
• Set the brew temperature via the PID controller (start at 93°C).

2. Grind Size and Dose: Getting the Basics Right

The Bianca is forgiving, but a good grind is essential. Use a quality grinder like the Baratza Sette 270 Wi or the Timemore Manual Handgrinder - C3S Pro for consistency. For a double shot, aim for 18-20 grams of ground coffee in the portafilter. The grind should be fine, similar to table salt, but adjust based on your extraction time.

Dose the coffee into the portafilter, then use a distribution tool or your finger to level the grounds. Tamp firmly and evenly. The Bianca comes with a tamper, but a calibrated tamper can improve consistency. Place the portafilter in the group head and you're ready to pull a shot.

• Use a scale to measure your dose—18-20g is ideal for a double shot.
• Ensure the grind is fine enough to achieve 25-30 seconds extraction.
• Tamp with even pressure to avoid channeling.

3. Brewing Your First Shot with Pressure Profiling

The Bianca's pressure profiling paddle is its signature feature. It allows you to manually adjust the pressure during extraction. Start with the paddle closed, then open it slowly to pre-infuse the coffee at low pressure (about 2-3 bars) for 5-10 seconds. This wets the grounds evenly and reduces channeling.

After pre-infusion, continue opening the paddle to ramp up to full pressure (9 bars). As the shot finishes, you can reduce pressure to avoid over-extraction. This control lets you highlight different flavor notes—try a gentle ramp for lighter roasts or a quick spike for darker ones. Experiment to find what suits your beans.

• Pre-infuse at low pressure for 5-10 seconds.
• Ramp up to 9 bars gradually for balanced extraction.
• Reduce pressure at the end to minimize bitterness.

4. Dialing In: Time, Yield, and Taste

Dialing in is the process of adjusting grind size, dose, and pressure to achieve the best taste. For a standard double shot, aim for a 1:2 ratio—if you use 18g of coffee, you want 36g of espresso in the cup. The extraction should take 25-30 seconds from the first drop. If it's too fast, grind finer; if too slow, grind coarser.

Taste your espresso and note the flavors. If it's sour, your extraction is underdeveloped—extend the pre-infusion or increase the brew temperature. If it's bitter, you're over-extracting—shorten the shot or reduce pressure. The Bianca's profiling allows you to fine-tune each variable, so keep a log of your settings for repeatability.

• Use a scale to measure yield—aim for 36g out for 18g in.
• Adjust grind size to hit 25-30 seconds extraction time.
• Keep notes to replicate your best shots.

5. Advanced Tips: Steaming Milk and Maintenance

The Bianca's dual boiler means you can steam milk and brew simultaneously. The steam wand is powerful—purge it before and after use to clear condensation. For silky microfoam, position the tip just below the milk surface and create a whirlpool. Aim for a temperature of 60-65°C for latte art.

Regular maintenance keeps the Bianca performing. Backflush the group head with water and a cleaning tablet weekly, and descale every few months depending on water hardness. Replace the water filter regularly. With proper care, your Bianca will last for years, delivering consistent espresso every day.

• Purge the steam wand before and after steaming.
• Backflush weekly with a cleaning tablet.
• Descale every 3-6 months to prevent scale buildup.

Mastering the Lelit Bianca takes practice, but the reward is espresso that rivals your favorite cafe. With its pressure profiling, you have the tools to experiment and refine your technique. If you're ready to upgrade your home setup, consider pairing the Bianca with a quality grinder like the Baratza Sette 270 Wi to unlock its full potential. Happy brewing!
