As long as it is cleaned after use and can be reused next time, it is also durable and strong made of stainless steel.

This article introduces the advantages and disadvantages of three kinds of coffee, but in fact, if you like coffee, you can try all three ways, choose your own suitable and favorite utensils, and brew a cup of coffee that belongs to you.

Suggestions for the use of filter paper: should filter paper be bleached or unbleached?

And there are two kinds of filter paper mainly sold in the market.

White bleached filter paper or wood-colored unbleached filter paper

What exactly does bleaching filter paper use to bleach?

In the past, many people chose to use unbleached filter paper because they were afraid that during the bleaching process, the remaining bleach (sodium hypochlorite) would flow into coffee with the boiling process, leading to chronic poisoning or cancer. And so on, cause adverse effects on health. But in essence, at present, large brands of filter paper are no longer bleached with traditional sodium hypochlorite, but are bleached with acid bleaching-enzyme bleaching to reduce health concerns.

The so-called acid bleaching mainly uses hydrogen peroxide (hydrogen peroxide) for bleaching, while enzyme bleaching uses biological enzymes for bleaching. Both bleaching methods have little impact on human health and can be said to be quite safe bleaching methods. At present, larger brands such as HARIO, KALITA, KONO, Sanyo … Etc., are either acid bleaching or enzyme bleaching, or both, are marked on the outer packaging of filter paper for consumers to choose from. It can be seen that there are basically no health doubts about buying bleached filter paper from big brands.

However, if you want to buy cheaper filter paper, it is recommended that you at least know its bleaching method and determine that it is acid bleaching or enzyme bleaching, which is safer and less risky. if you are not sure, it is recommended not to be greedy for petty cheap. after all, there are a lot of black-hearted goods in this day and age. no one can guarantee what will be eaten into the belly.

The problem of paper taste of unbleached filter paper

As long as the filter paper is made of pulp, if it is not bleached, it must have more or less pulp smell, and the filter paper must be washed with water to remove the paper odor. however, some thicker unbleached filter paper must use a lot of water to clean the paper flavor, which is quite unenvironmentally friendly and annoys people to wash filter paper. what's more, some filter paper will have paper flavor residue, resulting in more coffee flavor. This is also unbearable.

After all, I spent so much money on good beans and so much time to learn how to do it well. As a result, there is an extra smell of paper floating in the coffee, which directly destroys your perfect bracelet.
