Generally speaking, after 100ml vodka is mixed with the same amount of iced black tea, the brewing water and sweetness of the black tea will have a certain impact on the drinking effect, but the alcohol concentration of vodka is higher, which may cause slight drunkenness. Therefore, if you have no drinking experience or reliable drinking ability, it is recommended not to try drinking easily. At the same time, we should also pay attention to not driving, not dangerous operation, not indulging behavior after drinking, and maintain a safe and healthy drinking attitude.
