Don't believe everything you hear on Instagram and TikTok about matcha not coming into contact with metal utensils. For example, it's said that metal would damage matcha by oxidizing it.
✔ Oxidation is, as its name suggests, the result of contact with oxygen, not with metal. Moreover, there is frequent contact between tea and metal parts on the matcha production line. You must have also noticed that most tea tins are made of steel.
✔ Another thing we hear is that electric frothers would oxidize green tea powder. It's true that in this case, it's not "dry" contact since water is added.
In this case, it's important to remember that even if water oxidizes metal, the process is not fast enough to occur during the preparation of matcha, especially since these utensils are made of stainless steel. If the effect were as intense as claimed, it should be visible to the naked eye: the metal of the frother would become covered in black spots.
💡 Don't let this clarification stop you from buying a chasen (the bamboo whisk); it's versatile and the essential tool for making traditional matcha. With it, a whole world of possibilities opens up to you.
💡 To enjoy matcha at its best, drink it right after making it. Also, pay attention to storage: airtight packaging and stored in a cool, dark place. Once opened, consume within one month, otherwise, it will lose its flavor. You can, of course, come and drink or buy it at Marutcha where you are guaranteed that this product is treated with all the respect it deserves.
