What are the changes in the flavor of hand-brewed coffee over time? handmade pot is recommended.

Loose house style hand brewing coffee technique: use coarse ground coffee powder, stew for a long time, when brewing, 30CM is higher than the fine water column above the filter cup, and finally add hot water, this method is more prominent, which is a way to lead to the unique taste of coffee beans.

The flavor of coffee changes gradually with the passage of time, which may be affected by the following factors.

The first factor is the temperature characteristic of taste. Even if you taste the same thing, the sour, bitter and sweet taste will change as long as the temperature is different. When making a cold drink, it is less likely to feel bitterness and sweetness, but easier to feel sour.

The second factor is the change in composition. Coffee contains many ingredients that are easy to change, and if the brewing temperature is very high, it will change gradually.

The third factor is oxygen. The oxygen contained in coffee can change the coffee. I once heard the saying, "if you fill the whole kettle with coffee, you don't have to worry about exposure to oxygen." but this is a misunderstanding. Oxygen is dissolved in coffee, so this is only a palliative rather than a permanent cure.

So, what should I do if I want to maintain a good flavor for a long time? It is a pity that there is no perfect answer to this question. Keep the coffee frozen quickly and reheat it when you drink it. This method has some effect, but it must be evenly heated, not overheated, and must be finished in a short time, otherwise it will taste overcooked. Heating with a gas oven or microwave oven is easy to cause local overheating, and water-insulated heating takes a lot of time. Personally, you can enjoy iced coffee directly, or drink quick-frozen espresso with hot water, which is relatively simple. I think coffee is basically suitable for tasting when it is just made.

I hope you will learn to enjoy the different changes of a cup of coffee. As long as you can get rid of the preconception that coffee is a hot drink, you can see more coffee charm. People often say, "good coffee tastes good even if it's cold." in the process of drinking coffee, the temperature drops slowly, at the same time, the sour and bitter taste also gradually change the balance, stickiness increases, will produce a strong taste.

Insist on selecting, baking and mixing suitable raw beans, grind the beans before making coffee, and then take the time to taste them. I think this is the most luxurious enjoyment, isn't it?
