Boiling or lukewarm water for coffee?

If you use too cold water or warm water to brew coffee, it is easy to brew and cannot stimulate the beneficial components in the coffee, so it is recommended to use boiling water to brew coffee if possible.

It is better to brew coffee with warm water. The water temperature is between 85-95 degrees, which can be increased or decreased depending on how roasted the beans are. Boiling water tends to make coffee bitter and affects the effect of the aroma of the coffee.

The best water temperature for brewing coffee is between 88 and 94 degrees Celsius, and avoid using freshly boiled boiling water to brew coffee. After the water is boiling, let it sit for 1 2 minutes before brewing coffee.

When someone brews coffee with boiling and smoking water that has just been removed from the stove, I always imagine the taste of that cup of coffee in my head, and I think that a bitter taste will come out of the base of my tongue. Because coffee is not suitable for brewing with 100 degrees of boiling water, this will not only burn the coffee but also make the brewed coffee bitter and unpalatable, so you have to add a lot of sugar and creamer to taste.

In fact, the water temperature suitable for brewing coffee is about 85 degrees Celsius to 95 degrees Celsius, and the brewing temperature depends on how well the coffee beans are roasted. Roast shallow beans at a higher temperature. If you don't know how many degrees of hot water to use at first, it is recommended to start at 90 degrees, which is suitable for most coffee beans, and then adjust the temperature to your liking.

In order to accurately determine the temperature, a thermometer is necessary here, and there is also a basis if the brewing temperature needs to be adjusted due to temperature problems. In fact, as long as it is not freshly boiled water, it should not be too hot for coffee, such as the hot water in the thermos is usually kept at about 90 degrees, and you can take it out to brew coffee. As for the freshly boiled boiling water, just leave it to cool down naturally.

If you're really nitpicky about the temperature stability, the hot water used for brewing can be 3-4 degrees higher than the predetermined temperature, because you have to calculate the cooling caused by pouring hot water into a cold brewing container, so a few degrees higher is a reasonable estimate.

Coffee is brewed with water at 90 to 95 degrees, which is for medium or medium depth beans. If you are a dark roasted coffee bean, it is usually better to use a water temperature of 85 degrees.

In the process of brewing coffee, the active ingredients of coffee are used to maximize the use of only 50ml of water to brew 10 grams of coffee powder, which can use about 99% of the active ingredients, and the proportion of coffee brewed in this way is just right, and it is also particularly delicious.

Coffee shops that need to make coffee are usually calculated by the gram, and generally 10 grams of coffee beans are needed to make a cup of coffee.

Generally, when making hand-poured coffee, the ratio is 1:10 20, which is generally 1:15, that is to say, 10 grams of water are used for 1 gram of coffee beans.

The steps to make pour-over coffee are as follows:

Step 1: Prepare boiling water.

The most important ingredients for making pour-over coffee are boiling water and beans, so it is necessary to estimate the water to be used and boil it in advance, including the amount of rinsing utensils.

Step 2: Wet filter paper.

Evenly pour the pre-prepared boiling water on the filter paper, so that the filter paper is all wet, adhere tightly to the filter bowl, and then pour out the hot water in the sharing pot, this step also completes the warm cup.

The third lead step: prepare the ground coffee.

Prepare the right amount of coffee beans and grind them into ground coffee. Pour the ground coffee into the filter cup and gently pat it flat.

Step 4: Brewing & Extraction.

Pour the freshly boiled hot water evenly on the coffee grounds, be sure to control the flow rate of the water, the flow rate should not be too large, stop for 10 seconds when the water reaches half of the filter paper, so that the coffee powder can fully absorb water and expand.

Step 5: Finish brewing.

Pour in the rest of the water slowly, keeping the flow steady, and fill it in concentric circles in one direction up to the periphery of the ground coffee. Stop brewing enough water and wash the utensils.

The general water temperature for brewing coffee is between 85 and 92.

Do not boil the coffee, boiling water will make the coffee bitter, and the temperature of the water should be below 96 degrees Celsius. It's best not to reheat the coffee. Care should be taken to cook only the amount needed each time when brewing, and it is best to drink it freshly cooked.

The best temperature for coffee is 85 degrees Celsius.

Precautions for brewing coffee:

1. Use pure, odorless, and sweet-tasting water.

A cup of coffee is 98% water. Therefore, first see if the water used is qualified, the tap water in the city is not good, the taste of disinfectant water will affect the taste of coffee, and some families use high-end water purifiers, the taste of the water itself is very sweet, and the coffee that comes out of this way, although it is not difficult to drink, but it is not its original taste.

2. Master the correct grinding.

If you grind too finely, the taste will be too bitter and strong, and if you grind too coarsely, the taste will be too light, so you should be the right coarseness, and of course, there are subtle differences between different coffee beans and roast degrees.

3. Freshness.

Many people choose ground coffee for convenience, or grind a lot of it at once and keep it in the refrigerator. In fact, fresh grinding is the foundation of good coffee, it guarantees the taste of the coffee. When the coffee is ground into powder, the oxidation rate of the coffee powder will be accelerated, and the aroma will begin to dissipate within 40 seconds.

If the aroma of the coffee powder is seriously lost, the natural flavor of the coffee will disappear.

There are many people who feel that coffee is slightly bitter when drinking coffee, and at this time we can add some sugar in moderation, which can well neutralize the bitterness of coffee and make it better.

During coffee brewing and drinking, the specific brewing water temperature is related to the roasting degree of coffee beans, the coffee beans with a deeper roasting degree are best brewed with hot water with a slightly higher temperature, and the temperature is too low It is difficult to brew the true taste of coffee as a simple coffee liquid, but the maximum can not exceed 94 degrees, and the coffee beans with a lower roasting degree are ground into powder and brewed and drunk, the best water temperature should be 85 degrees.

The way the coffee is brewed

In the process of coffee brewing and drinking, the most conventional way is drip brewing, first grinding the coffee beans into coffee powder by machine, then putting it into a funnel-shaped filter paper moistened with hot water, slightly leveling it and putting it into the coffee cup, pouring hot water from above, and waiting for the coffee liquid to flow out of the filter paper to the coffee cup.
