As an expert sommelier and brewer, I can provide you with detailed information on how long opened seltzer can last in the fridge.
Firstly, it is important to note that seltzer, or sparkling water, should be consumed within a few days of opening for best quality and taste. Once you open a bottle or can of seltzer, it begins to lose its carbonation over time. To maximize the lifespan of opened seltzer, it is crucial to store it properly in the refrigerator.
After opening a bottle or can of seltzer, I recommend pouring it into a glass or cup instead of drinking it straight from the container. This allows you to fully assess the quality of the seltzer, including its level of bubbliness and any potential off odors or color changes. If you notice any unusual odors or colors, it is best to discard the seltzer as it may indicate spoilage or contamination.
When it comes to storing opened seltzer, resealing the container tightly and refrigerating it promptly is essential. The cold temperature of the fridge helps slow down the loss of carbonation and maintains the freshness of the seltzer. It is important to note that seltzer stored at room temperature will lose its carbonation much faster.
In terms of shelf life, opened seltzer can stay fresh for about two to three days if stored properly in the refrigerator. However, it is worth noting that the carbonation may start to diminish after the first day, resulting in a less fizzy seltzer. While it may still be safe to consume beyond this timeframe, the quality and taste may not be as enjoyable.
To summarize, opened seltzer should be consumed within two to three days if resealed and refrigerated. After the first day, the carbonation may begin to diminish, but the seltzer should still be safe to drink. It is important to use your senses to assess the quality of the seltzer, discarding it if there are any off odors or color changes. By following these guidelines, you can enjoy the optimal freshness of your opened seltzer for a few days.
