A guide to coffee

Whether you’re a seasoned barista or just starting to brew your own cup at home, making good coffee is both an art and a science. Here’s a guide to help you brew the perfect cup, every time.

1. Choose the Right Beans
– Bean Type: Coffee comes in two primary varieties: Arabica and Robusta. Arabica is known for its smooth, complex flavors, while Robusta is stronger and often more bitter. Most people prefer Arabica for its superior taste.
– Freshness: Always use fresh beans. Coffee beans start to lose their flavor within two weeks of roasting. Look for a roast date on the bag and aim to use your beans within a month of that date.

2. Grind the Beans Correctly
– Grind Size: The grind size should match your brewing method:
– Coarse: French press
– Medium: Drip coffee makers, pour-over
– Fine: Espresso machines
– Extra Fine: Turkish coffee
– Grinder Type: A burr grinder is preferred over a blade grinder because it provides a consistent grind, which is crucial for even extraction.

3. Use the Right Water
– Water Quality: Coffee is 98% water, so the quality of your water matters. Use filtered water to avoid any unwanted flavors from chlorine or minerals.
– Water Temperature: The ideal water temperature for brewing coffee is between 195°F and 205°F (90°C to 96°C). Too hot, and your coffee will taste bitter; too cool, and it will be under-extracted and weak.

4. Measure Your Coffee and Water
– Ratio: The standard coffee-to-water ratio is about 1 to 15-18. This means 1 gram of coffee for every 15-18 grams of water, depending on how strong you like your coffee. For reference, 1 cup of water is approximately 240 grams.
– Precision: Weigh your coffee and water using a kitchen scale for accuracy. This ensures you can replicate your perfect cup every time.

5. Choose the Right Brewing Method
– Drip Coffee Maker: Convenient and consistent, ideal for making multiple cups.
– French Press: Offers a rich, full-bodied coffee by steeping coarse grounds in water before pressing.
– Pour-Over: Allows for control over brewing time and water flow, which enhances flavor clarity.
– Espresso Machine: Creates a concentrated, strong coffee by forcing water through fine grounds at high pressure.
– AeroPress: A versatile and portable option that combines immersion and pressure, offering a quick and smooth brew.

6. Brew Time
– Each brewing method has an optimal brew time:
– Drip Coffee: 4-5 minutes
– French Press: 4 minutes
– Pour-Over: 2-3 minutes
– Espresso: 25-30 seconds
– AeroPress: 1-2 minutes
– Timing is essential to avoid over-extraction (which makes coffee bitter) or under-extraction (which makes it sour).

7. Enjoy and Experiment
– Taste Your Coffee: Pay attention to the flavour, aroma, and body of the coffee. Is it too bitter or too weak? Adjust your grind size, brew time, or coffee-to-water ratio accordingly.
– Experiment: Try different beans, grind sizes, and brewing methods to find what you like best. The beauty of coffee is that there’s always something new to discover.

By paying attention to these details, you can elevate your coffee from ordinary to exceptional. Remember, making great coffee is all about consistency and personalisation—what matters most is that you enjoy the final cup!
