Gowasu/Kvas (meaning "fermentation" in Russian and Ukrainian; Polish: kwas chlebowy, meaning "fermented with bread"; Lithuanian: gira；; Estonian: kali), a low-alcohol beverage popular in Russia, Ukraine and other eastern European countries, is brewed by dry bread fermentation, and its color is similar to that of beer but slightly red. Because its alcohol content is only about 1%. In Russian cities, Kvas can also refer to black tea fungus.
Netizen tucao
I'm going to have a good talk. First of all, the name makes people feel unacceptable, huh, "Gowasu"? What does it have to do with gas? In fact, a group of friends of mine drank this food when they traveled to the northeast long before it went to the South China market, and when they came back, they told me strangely that it was "liquid bread" from Russia. But as soon as I heard "liquid bread", I began to associate it: is it made of water bubbles to turn bread into liquid? Or let it mold and ferment until it is emulsified and liquefied? Either way, it's disgusting! Anyway, I don't even have the appetite to try a tongue.
Netizens described Gowasu in various ways: "The unpalatable version of beer and tea is refreshing", "Anyway, I feel unpalatable after living in Harbin for so long", and said that I thought it was pesticides or iodine, but I didn't want to drink it. Of course, a small number said it was like "honey beer". Personally, I think, maybe this thing is really popular elsewhere, but after it is introduced to the mainland, we still have to consider the acceptability of mainlanders. Don't start with words like "gas" and "liquid" that cause bad associations, because it has the first cause effect, and the first impression is hard to change, okay?
