There’s nothing more frustrating for coffee enthusiasts than pulling a shot of espresso only to be met with harsh bitterness or mouth-puckering sourness. Despite your best efforts with dosing, tamping, and timing, your espresso may still fall flat on flavor. What gives?
The problem often lies in two key variables: temperature and pressure. Inconsistent or poorly controlled brewing conditions can lead to under- or over-extraction, leaving your espresso off balance. Fortunately, with the Lelit Elizabeth, dialing in your espresso becomes both intuitive and precise, thanks to its dual boiler setup, PID temperature control, and pressure profiling capabilities.
In this article, we’ll walk you through how to use these tools to fix common taste issues and elevate your espresso game.
Why the Lelit Elizabeth is a Game-Changer for Espresso Precision?
The Lelit Elizabeth is part of a new generation of high-performance home espresso machines. Designed in Italy, it combines commercial-grade features with a user-friendly interface, giving coffee lovers the ability to fine-tune every aspect of the brewing process.
At the heart of its design is the Lelit dual boiler system: one boiler for brewing and another for steaming. This ensures that brewing temperature is not affected by milk frothing activities—an essential feature for maintaining consistency.
The lelit espresso coffee machine also features a digital PID controller for ultra-precise temperature adjustments and programmable shot controls. These advanced functions give you full command over how your espresso is extracted—and that means better flavor, every time.
Understanding Espresso Taste Problems: Bitter vs Sour
Before we dive into solutions, it’s important to understand what causes off-flavors in espresso:
Sour Shots
-
Caused by under-extraction
-
Water didn’t spend enough time in contact with coffee
-
Often a result of too low temperature or too coarse grind
Bitter Shots
-
Caused by over-extraction
-
Water pulled too much from the grounds
-
Often due to too high temperature or too fine grind
With the lelit elizabeth, you can make precise adjustments to both brew temperature and pressure, giving you tools to fix these issues quickly and systematically.
Using the PID Temperature Control to Tame Sour or Bitter Shots
The PID controller (Proportional Integral Derivative) built into the lelit elizabeth allows users to adjust brewing temperature in single-degree increments. Temperature plays a crucial role in extraction, particularly with different coffee roasts.
How to Adjust Temperature Using the PID?
-
Too sour? Increase the brew temperature by 1–2°C
-
Too bitter? Decrease the brew temperature by 1–2°C
Lighter roasts generally benefit from higher brewing temperatures (93–95°C), while darker roasts extract best at slightly lower temps (90–92°C).
The lelit dual boiler design ensures that each boiler maintains its own stable temperature. This means your espresso boiler holds steady during the shot, even if you’re simultaneously steaming milk.
Pressure Profiling with the Lelit Elizabeth
Another standout feature of the lelit elizabeth is its programmable pre-infusion and extraction pressure profiling. Pressure during extraction plays a major role in flavor balance, especially during the initial moments of the shot.
What Is Pre-Infusion?
Pre-infusion is a low-pressure phase at the start of extraction that gently saturates the coffee puck before full pump pressure is applied. This helps:
-
Reduce channeling
-
Promote even extraction
-
Enhance sweetness and clarity
How to Use Pre-Infusion on the Lelit Elizabeth?
The lelit espresso coffee machine allows you to program:
-
Pre-infusion time (in seconds)
-
Pause time (optional delay before full pressure)
-
Pump duration
Suggested Starting Points:
-
2–4 seconds of pre-infusion for medium/dark roasts
-
4–6 seconds for light roasts
You can experiment with these settings while keeping brew temperature and grind constant. Adjust one variable at a time to evaluate the taste difference.
Building a Consistent Dial-In Routine with the Lelit Elizabeth
Consistency is key when dialing in espresso. Here’s a reliable method using the features of your lelit espresso coffee machine:
Step 1: Set Your Dose
Choose your coffee dose (e.g., 18g for a double shot) and keep it consistent.
Step 2: Select a Starting Temperature
For medium roasts, start at 93°C. Adjust later based on taste.
Step 3: Program Pre-Infusion
Use a short 3-second pre-infusion and increase it as needed for even flow.
Step 4: Time Your Shots
Aim for a 25–30 second shot duration from the first drip. The lelit elizabeth includes a shot timer for accuracy.
Step 5: Taste and Adjust
Taste your shot and decide whether it needs to be sweeter, less bitter, or more balanced. Then adjust your temperature or pre-infusion accordingly.
Tips for Using the Lelit Dual Boiler Effectively
-
Always purge the grouphead before brewing to stabilize temperature
-
Use a scale to measure input and output for precision
-
Clean the grouphead and portafilter regularly to maintain shot quality
-
Backflush daily if using regularly to prevent buildup
The lelit dual boiler system heats up quickly and offers fast recovery between shots. This makes it ideal for users who brew multiple drinks in a row or entertain guests.
