How to Make Strong Coffee
If you're wondering how to make strong coffee, our guess is that you are looking for a caffeine fix or a brew that packs a bold punch of flavor. Either way, making strong coffee takes more than adding extra grounds to your brewer. Knowing the science and craft behind brewing techniques will help you get a strong and stimulating cup every time.
In this guide, we'll break down the factors that influence coffee strength and show you how to fine-tune your brew. From the beans you choose to the grind size and brewing method, every detail matters. As Hawaii's largest coffee grower, we know what it takes to craft a cup above and will help you unlock a stronger brew using our 100% Hawaiian Coffee.
What Makes Strong Coffee?
Strong coffee is a phrase with many meanings. To some, it means a dark roast, full body, or strong finish. For others, it's all about caffeine content. To us, coffee strength can refer to both flavor intensity and caffeine content. Several factors influence the strength of your coffee flavor and caffeine, including.
-
Variety and origin: Coffee beans grow in tropical climates all over the world and contain varying levels of caffeine and flavor compounds. Our team grows our 100% Hawaiian coffee at a low elevation in rich volcanic soil, which gives it a bold, smooth, and complex character. We also cultivate six unique varieties of coffee on our estate, each with unique characteristics and distinct notes.
-
Coffee-to-water ratio: The more coffee you use to the amount of water, the stronger your brew can taste. However, just increasing the amount of coffee you use can result in a bitter cup, so proceed with caution.
-
Grind size: You can extract a stronger flavor from your beans with a fine grind. This is why espresso tastes bold compared to drip-brewed coffee. However, using the wrong grind size for your brewing method can lead to a weak or astringent cup.
-
Roast level: Flavor strength and caffeine strength are not always linked. Dark roasts have a bold, rich flavor and slightly less caffeine when brewed properly, and lighter roasts may have brighter, floral notes and more caffeine content.
-
Brewing method and extraction time: Some brewing methods, like espresso and cold brew, naturally produce a stronger flavor. Cold brew relies on the extended brew time of hours in the refrigerator to extract flavor and produce a highly concentrated coffee. Espresso uses pressure to extract flavor for a robust shot of coffee quickly.
Choosing the Right Coffee Beans
Making a great cup of coffee starts with great beans. If you want a strong brew, you need beans that deliver flavor and body. At Kauai Coffee, we grow, roast, and blend our single-estate varietals to create unique offerings ideal for strength seekers.
-
Peaberry Dark: Peaberrys are unique, single-bean mutations that are known for their concentrated flavor and natural intensity. Most coffee cherries produce two seeds inside, so when just one peaberry forms, it concentrates all of the flavor compounds into that single seed. Our Dark Roast Peaberry takes the already strong flavor to another level! It brews a full-bodied cup with layers of complexity and low acidity.
-
Poipu Estate Espresso Roast: This coffee is strong and smooth with a delicate but deep aroma. The body is well-founded with floral notes that add to the buttery mouthfeel. It's a go-to for bold espresso and moka pot brews.
-
Typica Dark: This is a flavorful and well-balanced coffee with a hint of tartness. If a taste of paradise is what you're looking for, Typica is a must. This varietal was one of the first brought to the Hawaiian Islands for cultivation.
Grinding for Strength
Grind size is a key element in brewing strong coffee. It determines how much surface area of the bean is exposed to water and how much flavor is extracted during brewing. A finer grind allows more contact with water and results in a stronger brew. A fine grind is ideal for espresso, moka pot, and AeroPress brewing methods. A medium grind works for most drip machines, while a coarse grind is best for French press and cold brew.
If your coffee tastes weak, your grind may be too coarse. If it tastes overly bitter, it may be too fine or over-extracted. Adjusting grind size gives you control without altering the bean or roast. For the best results, grind your beans just before brewing. Freshly ground coffee holds onto its strength and flavor longer than pre-ground coffee.
Best Brewing Methods for Strong Coffee
Some brewing methods naturally produce a stronger cup than others. Here are the top techniques to try if you want a bold brew using 100% Hawaiian Coffee.
-
Espresso: Espresso is brewed under pressure using finely ground coffee and a small amount of water. The result is a concentrated shot of bold, intense flavor in just 25 to 30 seconds
-
Moka Pot: The moka pot is a stovetop espresso maker that pushes water through finely ground coffee using steam pressure. It creates a strong, rich cup without a machine. For the best results, use dark roast beans.
-
French Press: Brewing with a French Press is an easy way to get a bold cup. The coarse grounds steep in the water for several minutes, resulting in a full-bodied brew.
-
Cold Brew Concentrate: Cold brewed coffee is smooth and strong. Use a ratio of 2 cups of coffee to 8 cups of cold water and steep for 12 to 16 hours. Once brewed, dilute with water or milk to taste, or enjoy it straight for a serious caffeine kick.
Each of these methods offers a different path to strength, so choose the one that fits your taste and tools.
Tips to Increase Strength Without Bitterness
Making coffee stronger does not mean it has to be bitter! Follow these tips to keep it smooth.
-
Use filtered water to ensure that hard water or mineral build-up doesn't affect flavor.
-
If you prefer medium and light roasts, increase your coffee-to-water ratio instead of brewing a dark roast.
-
Heat your water to a temperature between 195- and 205-degrees Fahrenheit. Water that is too cool may lead to weak, under-extracted coffee, while water that is too hot may over-extract and taste acrid and burnt. If you don't have a thermometer, let your water come to a full boil, then wait 30 seconds before pouring over your grounds.
-
Store your coffee in an airtight container away from direct sunlight.
-
Use fresh, whole bean Kauai Coffee, or order your beans custom ground to your preference!
