Is it true that stainless steel water cups cannot be used as coffee cups and tea cups?

I have written many articles and videos about whether stainless steel cups can be used to brew coffee or tea. However, recently, some of my videos showing spraying of cups have become popular, and the comments under these articles or videos about brewing tea or coffee with stainless steel cups have also increased. http://www.umbottle.com/ProductsDetail-VB-10422.htmlMany friends think that it is not good to brew tea or coffee with stainless steel cups, and they insist that there is a peculiar smell and the taste is worse. Today, I will share this content with you again.

Why can stainless steel cups be used to brew tea and coffee?

Friends who have different opinions, please read the editor's article first. First of all, the editor wrote this article not because of personal usage habits and preferences, nor because of the editor's own paranoia. http://www.umbottle.com/ProductsDetail-VB-10422.htmlThe editor uses professional experience and many users to speak objectively for everyone.

Will the taste of coffee change when drinking from a stainless steel cup?

1. Answer: Yes. I always feel that the coffee tastes weird after using a stainless steel cup, unlike ceramic or glass cups, which can keep the mellow aroma of coffee. http://www.umbottle.com/ProductsDetail-VB-10422.htmlThis is the reply of most friends, and some friends even say that the taste is weird and difficult to drink.

2. Answer: No. To ensure that the coffee brewed in a stainless steel cup does not change its taste, the first thing is to use qualified materials. Qualified food-grade 304 stainless steel and 316 stainless steel will not cause a significant change in the taste of the coffee after brewing coffee. http://www.umbottle.com/ProductsDetail-VB-10422.htmlIf the material is inferior or replaced, such as using 201 stainless steel to impersonate 304 stainless steel, or using recycled steel to impersonate qualified food-grade steel, etc., the material is not qualified and the nickel, chromium and manganese content is increased, which will be integrated into the coffee when brewing, causing the coffee taste to change.

Secondly, the production process and storage management of the water cup are not done well. For example, stainless steel products are very easy to be contaminated by oil during the production process. If they are not cleaned before use, the taste of the coffee will change. Finally, it is because the stainless steel water cup has fast heat conduction or long heat preservation time. Usually we use glass water cups or ceramic water cups to brew coffee. http://www.umbottle.com/ProductsDetail-VB-10422.htmlDue to the material, the temperature conduction is relatively uniform and the heat dissipation is relatively fast. The taste of the coffee cup will change with the change of temperature. If it is a single-layer stainless steel water cup, the heat dissipation is faster, and the coffee brewing market also determines the difference in coffee taste; if it is a double-layer stainless steel thermos cup, the heat preservation time is too long and the coffee cools slowly, which will also cause changes in taste.

Solution: When drinking coffee from a stainless steel cup, after confirming that the material is qualified, you should thoroughly clean the coffee cup. It is recommended to use warm water and a gentle scrubber to clean it. http://www.umbottle.com/ProductsDetail-VB-10422.htmlA dishwasher is even better. Before drinking hot coffee, pour a cup of hot water at the same temperature as the brewing temperature into the stainless steel cup, let it stand for 1 minute, then pour it out and brew it. In this way, even if no coating is added to the inside of the stainless steel cup, the taste of the coffee will not change. The operation of a single-layer stainless steel cup is the same as that of a double-layer stainless steel cup.

What should you pay attention to when making tea in a stainless steel cup?

In addition to some of the same precautions as brewing coffee, the editor will talk about some differences and precautions when using a stainless steel cup to make tea.

Try not to use a stainless steel cup to brew green tea, because the taste of green tea changes sensitively, and the phytic acid content in green tea is higher than other teas. Long-term use of a stainless steel cup to brew green tea will indeed corrode the stainless steel. In addition, when using a double-layer stainless steel thermos cup to brew tea, no matter what kind of tea it is, never open the lid to brew tea. http://www.umbottle.com/ProductsDetail-VB-10422.htmlAfter the tea leaves are soaked, it is recommended to pour out the tea dregs and only keep the tea water in the cup, then cover it to keep it warm or carry it. Due to the excellent heat preservation performance of the thermos cup, if the tea leaves and tea water are kept in the thermos cup after brewing tea at high temperature, the tea leaves will be boiled by the high-temperature tea water if the lid is covered for a long time, which will seriously affect the taste of the tea.

Let's think carefully about this. How do you drink tea or coffee from a stainless steel cup every day? Especially when drinking tea, do you just put the lid on the tea leaves after brewing them? http://www.umbottle.com/ProductsDetail-VB-10422.htmlOr even wait for half an hour before drinking?
