We, like many of you, believe that brewing coffee is a ritual. With the right techniques and a bit of patience, anyone can discover their perfect cup of coffee. Whether you’re a newcomer or have been brewing for years, understanding the basics of ratios, grind size, water temperature, and equipment can make all the difference. So, let’s take a look.
The Basics: Water-to-Coffee Ratio
One of the most crucial aspects of brewing coffee is the water-to-coffee ratio. It’s often overlooked, but getting this right is the first step to creating a well-balanced cup. The general rule of thumb is:
- 1:15 to 1:18 ratio (1 gram of coffee for every 15-18 grams of water)
For a stronger cup, use a lower ratio (1:15), and for a lighter brew, go higher (1:18). Experiment with this until you find what suits your taste best. Measuring your coffee and water accurately (using a kitchen scale, if possible) will help you achieve consistent results each time.
Grind Size: One Size Doesn’t Fit All
Next, let’s talk about grind size. The size of your coffee grounds affects how water interacts with them, which in turn influences the flavour of your brew. Here’s a quick guide:
- Coarse Grind: Resembles sea salt. Ideal for French press and cold brew.
- Medium Grind: Like sand. Perfect for pour-over and drip coffee makers.
- Fine Grind: Similar to table salt. Best for espresso and Moka pots.
If your coffee tastes bitter, your grind might be too fine. If it’s sour or weak, try a finer grind. Don’t be afraid to adjust – a small change in grind size can make a big difference.
Temperature: Finding the Sweet Spot
Water temperature is another key element that affects the flavour of your coffee. The sweet spot is between 90-96°C (195-205°F). If the water is too hot, it can scorch the coffee and leave a bitter taste. Too cold, and you’ll end up with an under-extracted, weak cup. A simple tip: after boiling your kettle, let it sit for about 30 seconds before pouring.
Equipment: Choosing Your Brew Method
The equipment you use plays a significant role in shaping your coffee’s character. Here’s a brief guide to some popular brewing methods:
French Press
This method is straightforward and forgiving, making it great for beginners. It allows for full immersion of the coffee grounds, which results in a rich, full-bodied brew. Use a coarse grind and a 1:15 ratio. Let it steep for about 4 minutes, then press down slowly.
Pour-Over (V60, Chemex)
The pour-over method brings out delicate, nuanced flavours in the coffee. It requires a medium grind and a steady, controlled pour. Start by blooming the coffee (wetting the grounds and letting them sit for 30 seconds), then pour the water slowly in circular motions. It’s a bit more hands-on but well worth the effort.
Espresso Machine
Espresso is a concentrated, bold shot of coffee. For this, you’ll need a fine grind and a strong 1:2 ratio (1 gram of coffee for every 2 grams of water). The key is pressure – it forces hot water through the grounds quickly, extracting rich, intense flavours in just 25-30 seconds. It’s a more technical method but can be incredibly rewarding once mastered.
Experiment and Enjoy the Process
At Stean’s Beans, we always encourage experimentation. The beauty of coffee brewing is that there’s no one-size-fits-all approach. Play around with the ratios, grind sizes, and brewing methods. Keep notes on what you liked and didn’t like – it’s all part of the journey to discovering your perfect brew.
In the end, the best coffee is the one that you enjoy. So, grab your favourite beans, experiment a little, and savour each sip. And if you need any help or want to learn more about brewing techniques, don’t hesitate to reach out – we’re here to share our passion and knowledge.
