How to Pull a Proper Espresso at Intellectual Cafe

If your espresso shots often taste sour, bitter, or weak, you're not alone—nailing the perfect shot is one of the biggest challenges in home or café brewing. Many factors influence the final cup: dose, grind size, water temperature, and extraction time all play critical roles. In this guide, based on the methods used by Intellectual Cafe , we break down exactly how they achieve a balanced, flavorful espresso consistently.

The key? A 1:2 brew ratio, 18–20g in and 36–40g out, extracted between 28–32 seconds at 93°C with a medium-fine grind. That’s the core formula Intellectual Cafe uses to pull reliable, well-balanced espresso shots every time.

What Makes a Good Espresso at Intellectual Cafe?

Intellectual Cafe focuses on consistency and balance in their espresso. They aim for a 1:2 brew ratio—18–20 grams of coffee yielding 36–40 grams of espresso. The target extraction time is 28–32 seconds, using water heated to 93°C. Their grind setting is medium-fine, adjusted to sit within a range that allows for steady flow without over- or under-extracting. This combination delivers a cup that’s neither overly sharp nor flat, balancing acidity, sweetness, and body effectively.

The Role of Grind Size and Dose

At Intellectual Cafe, grind size is medium-fine, which is crucial for slowing down water flow and allowing proper extraction. The dose is typically 18–20 grams, depending on the basket size. Using the right dose ensures even water distribution and pressure during extraction. Too fine a grind can lead to channeling or bitterness; too coarse, and you’ll get under-extracted, sour shots. Consistency in grind is essential—they likely use a high-quality grinder with minimal retention to maintain uniformity shot after shot.

Brew Ratio, Temperature & Time Targets

The cafe adheres strictly to a 1:2 brew ratio: for every 18–20g of ground coffee, they aim for 36–40g of espresso. Water temperature is set to 93°C, which is considered optimal for extracting the desired flavours without over-extracting bitter compounds. Extraction time is targeted between 28–32 seconds. This combination—ratio, temperature, and time—is carefully calibrated to produce a balanced shot with a good crema, clear sweetness, and a rounded body. Timing is especially important: starting the timer when water first hits the coffee ensures the full extraction window is observed.

Step-by-Step: How Intellectual Cafe Pulls Their Espresso

Here’s how Intellectual Cafe achieves their signature espresso:

• Grind 18–20g of coffee to a medium-fine setting.
• Dose the grounds into a portafilter, distribute evenly (they may use a WDT tool or similar method), and tamp with consistent pressure—around 30 pounds or firm enough to create an even puck.
• Preheat your espresso machine and portafilter. Flush a little water through the group head to stabilise temperature.
• Immediately place the portafilter into the machine and start the shot as water contacts the coffee—start your timer.
• Extract 36–40g of espresso over 28–32 seconds. Aim for a steady flow that looks like warm honey—neither too fast nor too slow.
• Stop the shot once you hit the target weight or time. Evaluate the crema, flavour balance, and body.

The goal is a shot that tastes balanced—not overly acidic, bitter, or thin—with a velvety crema and a well-rounded mouthfeel.

Common Mistakes to Avoid

Several common issues can derail your espresso:

• Incorrect grind size: Too fine, and you risk over-extraction and bitterness; too coarse leads to sourness and under-extraction.
• Poor distribution or tamping: An uneven puck causes channeling, where water finds the path of least resistance, extracting some areas too much and others too little.
• Wrong dose or ratio: Deviating from the 18–20g dose or 1:2 ratio alters extraction balance.
• Temperature instability: Fluctuating brew temperatures affect extraction consistency.
• Timing errors: Not starting the timer when the water hits the coffee, or ignoring the 28–32 second window, leads to inconsistent results.

Attention to these details helps ensure a more reliable and enjoyable espresso shot.

Frequently Asked Questions

What espresso ratio does Intellectual Cafe use?

Intellectual Cafe uses a 1:2 brew ratio—this means for every 18–20 grams of coffee, they extract 36–40 grams of espresso. This ratio is widely regarded as a solid standard for balanced espresso, providing enough strength and complexity without over-extracting.

What temperature do they brew espresso at?

They brew at 93°C. This temperature is considered ideal for extracting the desirable flavours from coffee—balancing sweetness, acidity, and body—without pulling out overly harsh or bitter compounds.

How long should an espresso shot take to pull?

An espresso shot should take 28–32 seconds from the moment the water hits the coffee. This time frame, combined with the right dose and grind, ensures proper extraction. Faster or slower times usually indicate issues with grind size, dose, or tamping.

What grind size is best for espresso at Intellectual Cafe?

They use a medium-fine grind. This grind is fine enough to slow water flow for proper extraction, but not so fine that it causes excessive pressure or over-extraction. It's the most common starting point for balanced espresso.

How much coffee should I use for a double shot?

Intellectual Cafe uses 18–20 grams of coffee for a double shot. This is typical for a standard double basket. The exact dose can vary slightly depending on the basket size and desired strength, but staying within this range helps maintain consistency.

Why is my espresso sour or bitter?

Sour espresso is often under-extracted—caused by too coarse a grind, too fast a flow, or too short a brew time. Bitterness usually means over-extraction, from a grind that’s too fine, a shot that’s too long, or water that’s too hot. Adjusting grind size, dose, and time usually fixes these issues.
