New to making your own coffee at home? Whether you’re trying to cut the daily trip to the coffee shop out of your routine and budget, or you just love the idea of brewing your own cup to start the day, this guide will break down the basics of coffee prep. Read on to unlock the keys to the perfect cup.
Step 1: How to Grind Coffee Beans
Every good cup starts with the coffee beans. The way you grind whichever beans you choose has a significant impact on the taste, strength, and balance of the final brew, so this first step is important to achieve your desired result. When grinding your coffee beans, both the method and size of the grounds matter.
Grind Methods
- Burr grinder: This method is the most widely recommended because it provides the most consistent grind size for optimal, even brewing.
- Blade grinder: This popular option works by smashing the coffee beans. It’s recommended to use short, 2–3 second pulses, shaking intermittently to ensure more even grounds.
- Blender: If you don’t own a dedicated coffee grinder, you can also use a blender on “grinder” or pulse setting, which helps to avoid overheating.
Grind Size
- Coarse: Aim for the consistency of sea salt. This size is best for French press or cold brew methods that allow for longer brewing time.
- Medium: Grounds should resemble the texture of sand. Medium grounds will produce the best results for drip coffee makers and pour-over.
- Fine: Grind the coffee beans until they look and feel similar to flour. This grind size is ideal for espresso or Turkish coffee that needs to be tightly compacted.
Note: The correct grind size for your chosen method ensures that water extracts the correct amount of oil and desired flavors and helps avoid coffee that is either bitter or too weak.
Step 2: The Right Coffee-to-Water Ratio
Knowing the correct coffee-to-water ratio will give you consistency in strength and flavor, no matter how much coffee you want to make. The exact ratio ultimately depends on how strong you like your coffee, but in general, the standard ratio is 1:16 to 1:17 (or 1 gram of coffee for every 16–17 grams of water). If you don’t have a coffee or food scale, you can also measure this using a coffee scoop or measuring spoon, with 2 tablespoons of ground coffee for every 6 ounces of water.
Step 3: The Correct Water Temperature to Brew Coffee
To achieve the optimal flavor extraction from your coffee grounds and avoid a bitter or weak brew, you want water that is just below boiling. The ideal temperature range is between 195°F and 205° F. Water that is too cool will produce coffee that is sour or weak; water that’s too hot leads to over-extraction, with coffee that tastes bitter or harsh.
For an easy way to ensure your water is at the right temperature, we recommend using a temperature-controlled kettle, like the Cosori Original Gooseneck Kettle. If you don’t own an electric kettle or thermometer, you can also bring water to a boil and then let it sit off the heat for about 60 seconds before pouring over your coffee.
Step 4: Make Small Adjustments to Perfect Your Brew
Once you have the basics of steps 1–3 dialed in, you can adjust different variables, like the coffee-to-water ratio, grind size, brewing method, or the type of coffee you use. For the best results, adjust one variable at a time to observe how each minor adjustment impacts the flavor and balance of the coffee. Using this approach will help troubleshoot common brewing issues you encounter. This method is especially helpful if you’re a coffee beginner and looking to discover your preferences and tastes. Eventually, these small adjustments can lead you to a cup of coffee you look forward to making and enjoying every day.
How to Store Coffee Beans to Preserve Freshness
Over time, coffee beans will lose their peak potency and flavor, especially if they aren’t stored properly. Generally, coffee beans stay fresh for 1–3 weeks after opening. For optimal flavor, it’s recommended to use coffee beans within this timeframe. If you don’t make coffee at home regularly, be sure to store the beans in a cool, dark, dry place, ideally in an airtight container to avoid oxidation which causes stale coffee. Avoid direct sunlight, moisture, freezing, or refrigeration to extend the shelf life of your coffee beans.
Though coffee rarely “expires” and is still safe to drink past its prime, there are a few indications that your coffee has aged. Look for a lack of aroma, a flat, flavorless taste, and a lack of bloom (or CO2 release) when hot water is added. All of these are signs that it’s time to purchase fresh coffee beans. (Tip: Old coffee grounds are great for garden fertilizer or composting!)
Building Your Coffee Routine
With these basics in your back pocket, you can start to build a coffee routine that delivers both delicious coffee and an enjoyable ritual to begin each day. These steps and tips are designed to help you create a routine that is simple, repeatable, and customizable to your tastes and preferences. With a little time and practice, you can find consistency and confidence in your coffee-making abilities. Happy brewing!
