What grind size is best for espresso?

Espresso requires a fine grind, similar to the texture of fine sand or table salt. This allows water to extract flavours properly under pressure within a short time.

How much coffee should I dose for a single espresso shot?

A typical espresso dose ranges from 16g to 20g of ground coffee. Using a digital scale helps ensure consistency and better tasting shots.

Why does my espresso taste bitter or burnt?

Bitter or burnt flavours usually indicate over-extraction caused by too fine a grind, too high a dose, or a too-long extraction time. Adjust grind coarser or reduce dose.

How do I fix an espresso shot that pulls too fast?

If your shot pulls too quickly (under 20 seconds), your grind is probably too coarse or your dose too low. Try grinding finer or increasing your dose slightly.

Can I use decaf coffee for espresso?

Absolutely! Decaf blends like Drizzly’s Pure Bliss Decaf offer smooth caramel and fruity notes that work well for espresso without the caffeine kick.

Espresso Grind and Dose Basics: Australian Coffee Guide for Perfect Shots

If you’re keen to pull a cracking espresso shot at home, understanding the basics of grind size and dose is the place to start. These two factors are the foundation of espresso brewing, influencing flavour, strength, and balance. In this guide, we’ll walk you through everything you need to know about espresso grind and dose, with practical tips and common troubleshooting advice—all explained with the friendly, knowledgeable tone of a true-blue Aussie coffee expert.

What Is Espresso Grind Size and Why Does It Matter?

Espresso grind size refers to how fine or coarse your coffee grounds are. Unlike drip or French press coffee, espresso requires a very fine grind because the extraction happens quickly under high pressure. The grind size needs to be just right to allow water to flow through the coffee at the perfect rate.

“Grind too coarse, and your espresso shot will be watery and sour. Grind too fine, and the shot will be bitter or even blocked.”

Think of grind size as the gatekeeper of flavour. It controls how much surface area the water touches and how fast it passes through the grounds. This balance impacts the taste, crema, and body of your espresso.

How to Identify the Right Grind Size

Start with a grind that looks like fine sand or table salt.
If your shot pulls too fast (under 20 seconds for 30ml of espresso), your grind is too coarse.
If it pulls too slowly or not at all (over 30 seconds), your grind is too fine.
Adjust in small increments to dial in the perfect texture.

Understanding Espresso Dose: How Much Coffee to Use

Espresso dose is the amount of ground coffee you use for a single shot. The standard dose for a single espresso in Australia usually ranges from 16g to 20g, depending on your machine and personal preference.

Dose affects the strength and balance of your espresso. Too little coffee and your shot will be weak and under-extracted; too much can cause over-extraction and bitterness.

Practical Dose Guidelines

Use a digital scale for accuracy—aim for a dose between 16g and 20g.
Adjust dose depending on the roast and blend. For example, a darker roast like Dark Ember – Intense Caramel & Chocolate Fire may require slightly less dose due to its strength.
Consistency is key—keep your dose the same to better evaluate grind size adjustments.

Step-by-Step: Dialling in Your Espresso Grind and Dose

Here’s a simple routine to get your espresso shots tasting spot-on:

Measure your dose: Use a scale to weigh your coffee dose precisely.
Set your grinder to a starting grind size (fine sand texture).
Tamp evenly: Use a tamper to compress grounds with consistent pressure.
Pull a shot and time it; aim for 25-30 seconds extraction for a 30ml espresso.
Assess taste: If it’s sour or weak, grind finer or increase dose slightly; if bitter or harsh, grind coarser or reduce dose.
Repeat adjustments in small steps until flavour, texture, and timing align.

Common Mistakes and How to Avoid Them

Inconsistent dosing: Weigh your coffee every time to avoid flavour swings.
Incorrect grind size: Don’t guess—adjust based on shot timing and taste.
Uneven tamping: Press grounds evenly to avoid channeling and uneven extraction.
Using stale coffee: Freshness matters; grind just before brewing.

Troubleshooting Your Espresso Shots

Here’s a quick guide to fix common espresso issues related to grind and dose:

Choosing Coffee Beans for Espresso

While grind and dose are crucial, the coffee bean itself plays a big role. Darker roasts tend to excel in espresso due to their robust flavour and lower acidity. For example, the Dark Ember – Intense Caramel & Chocolate Fire blend is a brilliant choice for espresso lovers who enjoy a bold, caramel-rich cup.

Final Takeaway: Grind and Dose Are the Espresso Pillars

Getting your espresso grind and dose right is essential for a delicious, balanced shot. Use a fine grind similar to table salt, dose between 16g and 20g, and adjust based on shot timing and taste. Keep your coffee fresh, tamp evenly, and be patient with small adjustments. With practice, you’ll consistently pull espresso shots that make your mornings or flat whites truly shine.

For those exploring espresso blends, consider starting with Drizzly’s Dark Ember – Intense Caramel & Chocolate Fire or, if caffeine is a concern, the Pure Bliss Decaf – Smooth Caramel & Fruity Delight as excellent options to experiment with your grind and dose.
