Coffee Grinder Guide: How to Choose the Right Coffee Grinder in Australia
A good coffee grinder can make a bigger difference to your coffee than many people expect. Whether you are making espresso at home, brewing filter coffee or running a café, the grinder determines how consistently your coffee beans are ground and how easily you can control your extraction.
Choosing a coffee grinder can also be confusing. There are espresso grinders, filter grinders, single-dose grinders, hopper grinders, hand grinders, on-demand grinders and grinders with different burr sizes and adjustment systems.
This coffee grinder guide explains the key differences, what to look for when buying a grinder, and how to choose the right option for your coffee setup in Australia.
Why Is a Coffee Grinder So Important?
Coffee beans need to be ground before brewing, but the size and consistency of those grounds have a major effect on extraction.
A grinder that produces a consistent particle size makes it easier to control your brewing process. An inconsistent grind can make some coffee particles extract too quickly while others extract too slowly.
For espresso in particular, small changes in grind size can have a noticeable effect on extraction time and flavour.
This is why a quality grinder should be considered an important part of your coffee setup rather than simply an accessory.
What Type of Coffee Grinder Do You Need?
The first decision is to choose a grinder designed for the type of coffee you normally brew.
Espresso Coffee Grinders
Espresso requires a relatively fine and precisely adjustable grind. An espresso grinder should allow you to make small adjustments so you can dial in your coffee recipe.
Espresso grinders are available in both single-dose and hopper-based designs. Some models are designed for manual dosing, while others can automatically deliver a programmed dose.
Precision Coffee Tools offers espresso grinders including the GS2, GS7, GS30 and GSP models.
Filter Coffee Grinders
Filter coffee generally requires a different grind range from espresso. A grinder designed specifically for filter brewing can make it easier to achieve the particle size required for methods such as pour-over and other filter brewing techniques.
Precision Coffee Tools offers dedicated filter grinders including the GS1, GS3 and GS5.
For example, the GS1 is designed for filter coffee and uses a 64mm filter burr with micrometric grinding adjustment.
Single-Dose Coffee Grinders
A single-dose grinder is designed around weighing your coffee beans before grinding rather than keeping a large quantity of beans inside a hopper.
This workflow can be useful for home baristas who frequently change coffee beans or want greater control over each dose.
The Precision GS0 V2 is a single-dose coffee grinder available in the Precision range.
On-Demand Coffee Grinders
On-demand grinders are designed to grind coffee when you need it. They can be particularly useful for espresso workflows where speed and repeatable dosing are important.
The Precision GSP is an espresso on-demand coffee grinder and is part of the current grinder range.
Hand Coffee Grinders
Hand grinders use manual effort rather than an electric motor. They can be a practical choice for travel, occasional brewing or anyone who prefers a compact coffee setup.
Precision Coffee Tools currently offers both Timber Hand Grinder and Black Hand Grinder options.
Burr Grinder vs Blade Grinder
When choosing a coffee grinder, you may come across blade and burr grinders.
Burr Grinders
Burr grinders crush coffee beans between two grinding surfaces. The distance between the burrs determines the resulting grind size.
Burr grinders are commonly preferred for espresso and specialty coffee because they provide greater control over grind size and are designed for more consistent grinding.
Blade Grinders
Blade grinders chop coffee beans using a rotating blade. They can be inexpensive and simple, but they generally provide less control over the consistency of the resulting grounds.
If you are serious about controlling your espresso or filter brewing process, a burr grinder is generally the more suitable type of grinder to consider.
What Is Burr Size?
Burr size refers to the diameter of the grinding burrs used inside a grinder. You may see specifications such as 60mm, 64mm or 80mm.
Burr size is one specification to consider, but it should not be used by itself to determine whether one grinder is better than another.
The burr design, motor, adjustment system, intended brewing method and overall grinder design also matter.
For example, the Precision GS7 uses 60mm flat espresso burrs, while the GS5 uses 80mm filter burrs.
What Is Grind Size?
Grind size describes how fine or coarse your coffee beans are ground.
Different brewing methods require different grind sizes.
| Brewing Method | Typical Grind Direction | Key Consideration |
|---|---|---|
| Espresso | Fine | Precise adjustment is important |
| Pour Over | Medium to medium-fine | Consistency and controlled flow |
| Filter Coffee | Medium | Even particle distribution |
| French Press | Coarser | Avoid excessive fine particles |
These are starting points rather than fixed rules. Your coffee beans, recipe, brewing equipment and personal taste can all affect the ideal grind setting.
What Is Grind Adjustment?
Grind adjustment allows you to change the distance between the burrs and therefore change the size of the coffee grounds.
Espresso brewing often benefits from precise adjustment because relatively small changes can affect extraction.
Some Precision grinders use micrometric grinding adjustment. The GS1, for example, includes micrometric adjustment for filter coffee.
Micrometric vs Stepped Grind Adjustment
Micrometric Adjustment
Micrometric adjustment provides very fine control over the grinding position. This can be particularly useful when dialling in espresso.
Stepped Adjustment
Stepped adjustment uses defined positions. Each click represents a predetermined change in grind size.
Neither system is automatically right for everyone. The best choice depends on your brewing method and how much control you want over your grind settings.
Single Dose vs Hopper Grinder
| Feature | Single Dose | Hopper |
|---|---|---|
| Bean storage | Usually weighed before grinding | Beans stored in hopper |
| Changing beans | Convenient for switching coffees | Less convenient when changing beans frequently |
| Workflow | Manual dosing focused | Fast and convenient |
| Best suited to | Home enthusiasts and varied coffee workflows | Regular brewing and higher-volume workflows |
How to Choose a Coffee Grinder for Home
For a home coffee setup, start by considering how you actually make coffee.
- Choose your brewing method. Decide whether you mainly make espresso, filter coffee or both.
- Consider your daily volume. A grinder used for one or two coffees a day has different requirements from one used by a busy household.
- Decide between single dose and hopper. Think about whether you regularly change coffee beans.
- Look at grind adjustment. Espresso users should pay particular attention to adjustment precision.
- Consider burr size and design. Compare the grinder's intended use rather than looking at burr size alone.
- Check dimensions. Make sure the grinder fits comfortably on your coffee bench.
- Consider cleaning and maintenance. Easy access to the grinding area can make routine maintenance simpler.
How to Choose a Coffee Grinder for a Café
Commercial users should consider additional factors such as daily volume, workflow speed, dosing method, grinder capacity and service support.
For a café, a grinder should be selected according to the menu, expected coffee volume and whether the grinder will be used for espresso, filter coffee or another brewing method.
The Precision GS7, for example, is an electronic espresso grinder with programmable single and double dosing, manual grinding and a 60mm flat-burr system.
For higher-volume or specialised filter workflows, the GS5 uses 80mm filter burrs and includes timed dosing and a touchscreen interface.
How Much Should You Spend on a Coffee Grinder?
There is no single price that is right for every coffee drinker.
A beginner may need a compact grinder for occasional brewing, while an experienced home barista may benefit from more precise adjustment and a more specialised espresso grinder.
Commercial users should consider the grinder as part of their overall café workflow rather than looking only at the purchase price.
The current Precision Coffee Tools grinder range covers different budgets and brewing requirements, from hand grinders through to higher-specification electric filter and espresso grinders.
How to Dial In an Espresso Grinder
Dialling in means adjusting your grinder and brewing recipe to achieve the extraction and flavour you want.
- Start with a consistent coffee dose.
- Grind the coffee and prepare the puck evenly.
- Record your dose and extraction result.
- Evaluate the espresso flow and taste.
- Adjust the grind size.
- Repeat until you reach the result you prefer.
A finer grind generally slows the flow of water through the coffee bed, while a coarser grind generally allows water to pass more quickly. Make small adjustments and evaluate the result rather than changing several variables at once.
Why Pair a Grinder With a Coffee Scale?
A coffee scale can help you measure your coffee dose and track the amount of brewed coffee produced.
This makes your brewing process more repeatable and can help when dialling in a new coffee.
Precision Coffee Tools also offers coffee scales that can be used as part of a complete espresso workflow.
What Other Coffee Tools Do You Need?
A grinder is only one part of a consistent espresso workflow.
Depending on your setup, you may also benefit from:
Using the right combination of grinder, dosing, distribution, tamping and measurement tools can make your coffee preparation process more consistent.
