How To Make Strong Coffee At Home

Share

there’s nothing quite like that first sip of a strong, robust cup of coffee. The rich aroma, the warmth, and the gentle kick of caffeine—it’s a ritual that millions of us cherish. But how do we consistently brew strong coffee without crossing the line into bitterness? Today, coffee enthusiasts, we’re about to explore the art and science of crafting the perfect cup of rich and strong cup of coffee minus the biterness.

Ingredients For The Perfect Strong Coffee

Filtered Water

Filtered water ensures that your coffee is free of impurities. Tap water often contains chlorine, minerals, and other substances that can alter the taste. When you brew with filtered water, you allow the coffee’s natural flavors to shine without interference.

Consistency matters. Imagine brewing a fantastic cup of coffee one day, only to end up with a mediocre one the next. Inconsistent water quality can lead to unpredictable results. By using filtered water consistently, you create a stable foundation for your brewing process. This allows you to focus on other variables—like grind size and brewing time—without unexpected surprises.

Fresh Coffee Beans
Freshness matters, and here’s why:

Oxidation: Coffee beans release volatile compounds over time. When grinding stale beans, they’re exposed to oxygen, which accelerates oxidation. In contrast, freshly ground beans preserve those aromatic compounds, enhancing flavor.

Complexity: Boldness doesn’t equate to bitterness. Fresh beans offer a spectrum of flavors—fruity, nutty, chocolatey—beyond mere bitterness. Staleness flattens this complexity, diminishing the overall taste experience.

Caffeine Kick: If you crave that morning jolt, opt for beans that haven’t lost their vigor. Fresh beans pack more caffeine punch, ensuring a robust start to your day! 

When we say fresh coffee, we’re looking for coffee that’s been roasted in it’s first month.  Beyond this point, coffee begins to lose it’s depth of flavor and will become more and more bitter.  If you’re looking for freshly roasted coffee, check your local coffee shops and ask if they roast their beans.  You may be surprised to find a roaster in your area.  There’s nothing like supporting locally home-grown businesses!

If you’re struggling to find a roaster in your area, several online options are super affordable and will only roast coffee in small batches weekly, ensuring your coffee is fresh.  I highly recommend Methodical Coffee, Trade Coffee Company, & Atlas Coffee.  You can order preground or beans and the bags will always inform you of when your beans were roasted!

Here are a couple of examples that I enjoy on a regular basis when I want a punch in the face from my coffee.  These beans also do very well for cold brew and are excellent choices for espresso:

Water and Water Temperature

Water quality and temperature are crucial factors in brewing a bold coffee, impacting both the extraction process and the final flavor profile. The importance of these elements cannot be overstated for coffee enthusiasts aiming for a rich, robust cup.

Water Quality:

Mineral Content: The right balance of minerals, such as calcium and magnesium, can enhance the extraction process, drawing out the complex flavors in the coffee grounds. Too many minerals can lead to an over-extracted, bitter taste, while too few can result in under-extraction, leaving the coffee flat and weak.
Purity: Using clean, filtered water ensures that no off-flavors from chlorine or other contaminants affect the taste of your coffee. The purity of water is fundamental for achieving the true character of the coffee beans.

Water Temperature:

Optimal Temperature Range (195°F to 205°F / 90°C to 96°C): This temperature range is ideal for dissolving the coffee’s soluble compounds efficiently. Water that’s too hot can extract undesirable bitter compounds, whereas water that’s too cool can fail to extract enough of the desirable flavors, resulting in a weak brew.

Consistent Temperature: Maintaining a stable temperature throughout the brewing process ensures even extraction. This consistency helps in achieving a balanced and bold flavor, avoiding the pitfalls of uneven extraction where some parts of the coffee grounds might be over-extracted while others remain under-extracted.

Together, high-quality water and the correct water temperature create a synergy that brings out the best in your coffee grounds, allowing for a bold and satisfying cup every time. By paying attention to these details, you can significantly enhance the depth and richness of your coffee, making every sip a true pleasure.

Equipment Needed For Strong Coffee

I know what you may be thinking; how will I control the temperature of the water if all I own is a drip brewer?  The question is valid as most home brewing machines don’t allow you to control temps.  However, there are a few that do.  I own one and it’s one of my favorite coffee tools that I own. It’s the Breville Precision Brewer which, not only allows you to control the temp, but will also bloom your coffee as well!  It’s a bit pricey but worth every penny, not to mention, Breville has excellent customer support!

However, if you’re not going out to purchase one today, an excellent second or third option is a French Press or a Hario V60 pour-over.  Both of these are inexpensive additions to your coffee collection that brew incredible cups of coffee.

Now, there are always questions surrounding the coffee grinder and if you could simply use coffee that’s pre-ground.  The answer is yes.  Just keep in mind that most pre-ground coffee, especially bought in a supermarket, is ground for drip coffee.  You can use this coffee, however, you’re going to be left with an unwanted sludge at that won’t be able to be filtered out from your french press.

  If you don’t have a grinder at home, there are cold brew kits that is ground for cold brew.  Alternatively, you can go to your local coffee shop, choose a bean and ask your barista to grind for French Press!

The Recipe For A Bold Cup of Coffee

Coffee is a lot like baking.  Using precise measurements of coffee grounds, size of grind to how much water, & temperature is key.  If you miss measuring one of these variables, you’ll never know what went wrong with an over/ under-extracted coffee.  For example, if using a ratio of 1 cup of water – 16 grams of coarse coffee and it tastes weak, you can simply add another gram to your next brew and repeat until you’re satisfied with the results.  

Let’s dive into the recipe:

For a stronger cup of coffee, especially when using methods like a French press, a commonly recommended coffee-to-water ratio is 1:15. However, for an even bolder brew, you can adjust this to a ratio of 1:12 or even 1:10. Here’s how to approach it:

  • 1:12 Ratio: Use 1 gram of coffee for every 12 grams of water. This ratio will yield a stronger, more concentrated flavor.
  • 1:10 Ratio: Use 1 gram of coffee for every 10 grams of water. This ratio will produce a very bold and intense cup of coffee.

To put this into perspective, if you’re making 355 grams of coffee, you would use:

  • 1:12 Ratio: About 30 grams of coffee grounds with 355 grams of water.
  • 1:10 Ratio: About 36 grams of coffee grounds with 355 grams of water.

Using these ratios ensures a stronger brew by increasing the concentration of coffee grounds relative to the amount of water, resulting in a richer and more robust cup. Adjusting the ratio to your taste preferences allows you to find the perfect balance for your ideal bold coffee experience.

If you decide to use the French Press method, heating your water to 200 degrees will ensure that you’ll have a nice, even extraction without adding any bitterness to the flavor.  

Here’s a simple French Press method inspired by James Hoffmann:


Measure/ Grind the Coffee:

Measure 36 grams of coffee beans.

Grind them to a coarse consistency, similar to breadcrumbs.

Heat the Water:

Bring 355 grams of water to a boil, then let it cool slightly to reach about 200°F (93°C).

Preheat the French Press:

Pour some hot water into the French Press to preheat it, then discard the water.

Add Coffee Grounds:

Place the 36 grams of ground coffee into the French Press.

Pour Water:

Start your timer and pour 355 grams of hot water evenly over the coffee grounds, ensuring all the grounds are saturated.

Stir:

After one minute, give the coffee a gentle stir to break up the crust that forms on the surface.

Let Steep:

Place the lid on the French Press with the plunger pulled up.

Let the coffee steep for a total of 4 minutes.

Skim the Top:

After 4 minutes, remove the lid and use a spoon to gently skim off any foam or coffee grounds floating on the surface.

Plunge:

Replace the lid and slowly press the plunger down to separate the grounds from the brewed coffee.

FAQ

What grind size should I use to make strong coffee?

The grind size depends on your brewing method. For a French press, use a coarse grind; for a drip coffee maker, use a medium grind; for an espresso machine, use a fine grind. The grind size affects the extraction rate, with finer grinds generally leading to stronger flavors but requiring shorter brew times.

How does the coffee-to-water ratio affect the strength of the coffee?

 A higher coffee-to-water ratio results in a stronger coffee. For example, using a ratio of 1:12 (1 gram of coffee to 12 grams of water) will produce a bolder flavor compared to a standard 1:15 or 1:16 ratio. Adjusting the ratio allows you to control the intensity of your brew.

What is the ideal water temperature for brewing strong coffee?

The ideal water temperature for brewing strong coffee is between 195°F and 205°F (90°C to 96°C). This range ensures optimal extraction of the coffee’s flavors. Water that is too hot can over-extract, leading to bitterness, while water that is too cool can under-extract, resulting in a weak and sour taste.

Can I make strong coffee without making it bitter?

Yes, you can make strong coffee without it being bitter by carefully controlling the brewing parameters. Use the correct coffee-to-water ratio, maintain an optimal water temperature, and ensure proper brew time. Avoid over-extraction by not brewing for too long and by using freshly ground coffee beans to enhance the flavor without excessive bitterness.
