How to Grind Coffee Beans at Home

If you want to get the absolute best results out of your coffee making experience, then the first and most important piece of equipment is a grinder. Without it you'll never achieve coffee perfection, so let's look at how you can get the best results when grinding your coffee beans at home.

Why Grind Your Own Coffee?

So why should you grind your own coffee beans when you can buy pre-ground coffee? Here are a few good reasons:

• Freshness: Coffee starts to lose its flavour within minutes of being ground. Grinding your beans just before brewing ensures maximum freshness.
• Control: Different brewing methods require different grind sizes. Grinding your own beans lets you tailor the grind to your specific brewing method.
• Aroma: Freshly ground coffee smells amazing. It’s like having the smell of a coffee shop in your kitchen.

Tools of the Trade

First things first, you’ll need a grinder. Here are the main types of grinders you can use at home:

1. Blade Grinder

A blade grinder is a versatile and inexpensive way of grinding coffee beans. But it’s not perfect for the task.

First of all they are affordable and easy to find. Most electrical stores and supermarkets will have them. However, they produce an inconsistent grind sized that can lead to an uneven extraction.

If you find yourself using a blade grinder, then make sure you grind in short bursts to minimise the amount of heat and get a more even grind.

2. Burr Grinder

Using a burr grinder is the best way to grind your coffee at home because they're purpose built for the job.

Essentially two abrasive surfaces (burrs) spin in close proximity and crush the coffee beans into uniform particles. This results in a very consistent and even grind size. In addition, adjustable settings mean you can tailor your grinding to different brewing methods, resulting in a much better flavour.

The downside is that they tend to be more expensive (you really do get what you pay for) and require regular maintenance and cleaning.

3. Manual (Hand-Operated) Grinder

A manual grinder is a cheaper alternative to a full-on burr grinder. Instead of an electric motor spinning the grinding burrs, you use a handle to crank it yourself.

You still achieve a consistent grind size and the great thing is that they're portable, so you can carry it round with you so that you can always have great coffee wherever you are.

Of course, the downside is that they're more time-consuming and require much greater effort. However, they're perfect if you travel a lot and want to feel more connected to your coffee-making process.

How to Grind Coffee Beans

Now that you’ve got your grinder, here’s a step-by-step guide for each type of grinder:

Blade Grinder

1. Measure Your Beans: For best results, use a scale. You need about 10 grams of beans as a good starting point.
2. Add Beans to Grinder: Place the beans in the grinder.
3. Pulse: Pulse the grinder in short bursts. Shake it a bit between pulses to mix things up.
4. Check the Grind: Stop grinding when you reach your desired consistency. For Cafetiere, a coarse grind, like granulated sugar, is desirable; for drip coffee, aim for medium like sand; for espresso, aim for fine. However, I wouldn't recommend this method for espresso - you won't be able to get it fine enough.

Burr Grinder

1. Measure Your Beans: Use a scale for accuracy. About 10 to 20 grams.
2. Set the Grind Size: Adjust the grinder to your desired setting. Coarse for Cafetiere, medium for drip coffee, fine for espresso.
3. Add Beans to Hopper: Pour the beans into the hopper.
4. Start Grinding: Turn on the grinder and let it do its thing. Most grinders have a timer so you can achieve repeatability.
5. Check the Grind: Inspect the grounds to ensure consistency.

Manual Grinder

1. Measure Your Beans: Use a scale for accuracy. About 10 grams to 20 grams.
2. Set the Grind Size: Adjust the grinder to your desired setting.
3. Add Beans to Hopper: Pour the beans into the hopper.
4. Start Cranking the Handle: If you want to build your muscles, then this is for you.
5. Check the Grind: Inspect the grounds to ensure consistency.

Hints and Tips

• Keep your coffee beans in an airtight container, away from light, heat, and moisture. A dark pantry is perfect.
• Grind only what you need right before you brew. This keeps your coffee as fresh as possible.
• Different brewing methods require different grind sizes. Don’t be afraid to experiment to find the perfect grind for your taste.
• Coffee oils can build up and affect the flavour of your coffee. Clean your grinder regularly to keep it in top shape.
• Your grinder’s sound can tell you a lot. If it sounds like it’s struggling, you might be grinding too many beans at once or the beans might be too hard (stale).

Grinding by Hand: The Mortar and Pestle Method

For the ultimate DIY coffee experience, you can grind your beans with a mortar and pestle. It’s labour-intensive but incredibly satisfying.

1. Measure Your Beans: About 10 grams to 20 grams should do it.
2. Add the Beans to the Mortar: Place the beans in the mortar.
3. Grind in Small Batches: Use the pestle to crush the beans up. Do this in small batches. Apply a twisting motion to grind them to your desired consistency.
4. Check the Grind: Inspect the grounds to ensure consistency.

Final Thoughts

Grinding your own coffee beans at home can really improve your coffee making experience. Whether you’re using a blade grinder, burr grinder, manual grinder, or even a mortar and pestle, the key is to enjoy the process and experiment until you find what works best for you. So go ahead, get grinding, and savour the freshest, most flavourful coffee you’ve ever had. Happy brewing!

And remember, as the old saying goes, “Life’s too short for bad coffee!”
