To brew a good cup of coffee, having great beans alone is far from enough—storage method, grind size, water temperature, and brewing technique all directly affect the flavor in the final cup. This article explores seven key details in coffee-making, from the temperature threshold for avoiding bitterness, to the golden ratio of coffee to water, to the flavor tipping point of holding time, offering practical tips for each. Whether you prefer a drip brewer or other brewing methods, these principles can help you avoid common pitfalls and consistently reproduce a clean, balanced, and fresh cup of coffee.
Fellow coffee drinkers know well that high-quality coffee beans are the foundation of a great cup. However, whether the storage method is appropriate, whether the grind size matches, and whether the brewing technique is correct also play a pivotal role in how the flavor comes through.
1. Never let coffee liquid reach a boil, or bitterness will become pronounced. The ideal heating range is 90°C to 96°C.
2. Do not repeatedly reheat coffee that has already been made. The safer approach is to make only as much as you'll drink, keeping each cup fresh. To preserve the coffee's optimal flavor as much as possible, maintaining it at around 86°C is ideal.
3. The water used for brewing should be fresh and on the cooler side. Water makes up as much as 98% of a cup of coffee. If the water source itself has off-flavors, consider switching to filtered or bottled water.
4. Do not reuse coffee grounds that have already been extracted. What remains in these spent grounds is essentially only the compounds that bring bitterness.
5. The grind size of coffee grounds must match the equipment you use. Grinding too fine causes over-extraction, bringing about bitterness and, in severe cases, clogging the equipment; grinding too coarse makes the coffee taste thin and watery. Taking a drip coffee maker as an example, the appropriate grind size should allow the coffee to finish dripping within 2 to 4 minutes.
6. Regardless of how much coffee you make at once, the recommended ratio is: for every 10 grams of coffee grounds (about two tablespoons), pair with 180 milliliters of water.
7. Keeping coffee warm on a stove should not exceed 20 minutes, as the flavor will deteriorate over time. If transferred to a vacuum thermos, the flavor can be maintained longer.
