Americans love to drink coffee. The American Coffee Association reported in 2020 that nearly 64% of Americans drink coffee regularly, and nearly 90% of people aged 30 to 40 drink coffee every day.In the past, Americans liked to drink coffee in cheap, convenient, and disposable paper and plastic cups. However, as people’s environmental awareness increases, paper and plastic cups are becoming less and less popular because they pose a threat to both the human body and the environment. Experts speculate that stainless steel tumblers coffee will lead this field.
So what is a stainless steel cup and can you put coffee in it?
Stainless steel cup is mostly made of stainless steel 18-8 (SUS304), a food-grade material that has been widely used in many industries and is environmentally friendly. So it is safe to put coffee in such a stainless steel cup.
How many stainless steel cup can you choose?
According to the number of cup walls and whether it has heat preservation properties, stainless steel cup can be divided into 3 types, as follows.
1. Single-wall insulated tumbler
Single-wall insulated tumbler has only one layer, and the price is relatively cheap. But it is not recommended because it cannot keep cold. If you take a sip of iced coffee, you will feel the coolness of the ice cubes on the outside of the cup, while the coffee itself will slowly return to room temperature, and the taste will be relatively discounted.
2. Double-layer insulated tumbler
Currently, most of the cups on the market are double-layer stainless steel insulated tumbler. This insulated tumbler is vacuum-treated, which will keep the coffee inside cold for a long time without affecting the taste. We often see this type of cup.
3. Double-layer stainless steel non-insulated tumbler
Currently, the price of this double-layer stainless steel non-insulated tumbler is relatively cheaper than double-layer stainless steel, but it is not very common. After all, it has no cold-keeping effect, so it is not popular with everyone.
Can stainless steel tumblers hold hot coffee?
Some people insist that coffee is an acidic liquid that reacts with stainless steel, changes the original flavor of coffee, damages the thermos itself, and releases harmful elements.
In fact, coffee will never react with stainless steel. The pH value of standard coffee is between 4.5 and 6.0, which is close to neutral. You may be surprised that the pH value of a bottle of Coke is close to 2.6! Some people like to add milk to their coffee to improve the taste and nutrition. This is OK because the pH value of milk is more neutral than coffee.
So the answer to this question is undoubtedly “yes”. Hot coffee does not chemically react with stainless steel. In addition, stainless steel will never bring odor to coffee, allowing you to enjoy the original taste that is difficult to achieve with paper or plastic cups.
In fact, the main parts of the coffee machine are made of food-grade stainless steel 18-8 (SUS304), which is the same material as the stainless steel tumblers. Coffee made by the machine will inevitably come into contact with stainless steel for a period of time. If stainless steel materials are incompatible with coffee or milk, why do people still use them? So, there is no problem with stainless steel tumblers for coffee.
How about the heat preservation ability of stainless steel water bottle?
FuWinn‘s stainless steel water bottle can keep your boiling coffee hot for up to 8 hours, or keep iced coffee cold for 12 hours. Between the two layers of stainless steel walls, there is a so-called “vacuum gap” that makes it difficult for heat to pass through.
If you want to keep your coffee warm for a longer time, there are two ways to enhance the heat preservation ability of stainless steel water bottle – either boil the coffee or preheat the inner wall of the cup with boiling water.
