How to Make Espresso at Home (Barista-Level Guide)

Espresso is the foundation of great coffee. When dialled in properly, it’s intense, syrupy, balanced, and packed with flavour.

If you’ve got fresh beans, a good grinder, and an espresso machine,here’s exactly how to pull a proper shot.

What You’ll Need

• Fresh coffee beans (roasted 1–4 weeks ago)

• Espresso machine

• Burr grinder

• Scales

• Tamper

• Portafilter

• Cup

Freshness matters. Beans older than 4–5 weeks lose vibrancy. Beans too fresh (under 5 days) can produce unstable, gassy shots.

 

The Standard Espresso Recipe

Dose: 22-23g ground coffee

Yield: 38-42g espresso

Time: 28-32 seconds

This is a reliable starting point for most modern espresso blends.

 

Step-by-Step: How to Pull the Perfect Espresso Shot

1. Dial in the Grind: Espresso requires a fine grind.

• Too coarse = fast shot, sour taste

• Too fine = slow shot, bitter taste

Start fine, then adjust based on extraction time and taste.

2. Dose Correctly: Weigh 22g of coffee into your portafilter basket (or adjust for your basket size).

Consistency is everything.

3. Distribute Evenly: Tap the portafilter gently to settle the grounds. Uneven distribution causes channelling, where water finds weak spots and extracts unevenly.

Optional upgrade:

• Use a WDT tool to break up clumps and improve consistency.

4. Tamp Firmly: Apply firm, level pressure using your body weight. You’re creating a compact coffee puck with:

• No air gaps

• No uneven edges

• No tilting

A level tamp is more important than brute force.

5. Extract the Shot: Lock in the portafilter and start brewing. Aim for:

• 42g liquid output

• In about 28-32 seconds

If your shot runs:

• Too fast → grind finer

• Too slow → grind coarser

 

How to Taste & Adjust Espresso

Sour Espresso?: Likely under-extracted. Try grinding finer or increasing yield slightly.

Bitter Espresso?: Likely over-extracted. Try grinding slightly coarser or reducing brew time.

Weak or Thin Body?: Increase dose slightly or grind finer.

 

Ideal Espresso Temperature

Most espresso tastes best between: 91–94°C

General guide:

• Lighter or medium roasts → slightly hotter

• Dark roasts → slightly cooler

Small adjustments can dramatically change flavour.

 

Advanced Espresso Tips (Home Barista Upgrade)

Use a Puck Screen: Helps improve water distribution and keeps group head cleaner.

Control Brew Temperature: If your machine allows, experiment within the 91–94°C range.

Use Fresh Beans: 1–4 weeks post roast is the sweet spot.

Flush Between Shots: Run a blank shot after brewing to keep your machine clean and stable.

Why Espresso Is Harder Than Other Brew Methods

Espresso uses:

• High pressure (9 bars)

• Fine grind

• Short brew time

• Tight extraction window

Small changes create big flavour differences. But once dialled in, nothing beats it.

 

FAQ: Espresso Brewing

How long should espresso take?

Around 28–32 seconds.

Why is my espresso sour?

Likely under-extracted, grind finer.

Why is my espresso bitter?

Likely over-extracted, grind coarser.

Pro Tip: Choosing the Right Coffee for Espresso

Espresso highlights:

• Body

• Sweetness

• Texture

• Intensity

For stronger flavour:

• Darker roasts = heavier body, chocolate notes

• Medium roasts = balanced and versatile

• High-caffeine blends = extra punch

If you want bold espresso with serious kick, start with a blend designed for strength and consistency.
