From a bar in NYC that only serves matcha, to matcha sold in bottles and cans, to matcha cookies, it’s likely that in the near future you won’t be able to open your eyes in the supermarket without seeing the word “matcha” in your field of vision. So what is it? Matcha is a beverage served traditionally in Japan. Essentially, it’s green tea—but with an important difference: rather than steeping whole green tea leaves in hot water, matcha consists of green tea leaves that have been pulverized into a powder and then added to water. Since you consume the whole tea leaf when drinking matcha, there are claims, supported by at least one study, that the amount of antioxidants in a cup of matcha exceeds the amount of antioxidants in a cup of regular green tea. Yet, regardless of its potential health benefits, which would be similar to those of regular green tea, matcha has a distinctive earthy flavor that makes it a delicious option simply for pure culinary enjoyment.
