The taste and quality of soda water may change after expiration, so it is not recommended to continue drinking. Expired sodas may become more alkaline, resulting in poor taste and possibly negative health effects.
If the expiration time of soda water is not long and the storage conditions are good, it may still be safe to drink. However, if the soda has expired for a long time or the storage conditions are poor, such as exposure to sunlight or high temperature, it is not recommended to drink it again.
In conclusion, in order to ensure health and safety, it is best not to drink the soda after it has expired, but to purchase new soda.
