Should you store soda in a refrigerator or cabinet after been opened?

Refrigerator.

After opening a can or bottle of soda, the remaining contents should be refrigerated to maintain freshness and quality. Cooling slows the growth of bacteria and other microorganisms that can cause spoilage and alter the taste of the soda. Refrigeration also helps preserve the carbonation and flavor by minimizing the escape of carbon dioxide gas. Storing opened soda at room temperature or in warm conditions can lead to faster deterioration and loss of carbonation.
