Remember, rice vinegar can hasten its shelf life on exposure to sunlight. Therefore always keep the bottle in a cool and dark place, far from any source of heat and light. The pantry would be a great store, but a corner cupboard will also do the job.

Sealing the bottle plays a key role in storing the vinegar. Once you break the seal, make sure to close it after use tightly. If the vinegar has a higher alcohol concentration, it can evaporate quickly if not tightly sealed.

Once the seal is broken, many chefs recommended changing the bottles and storing the rice vinegar. When you change the bottle, make sure to shift it into a glass bottle. Do not use metal or plastic bottles at any cost.
