Brine pickles can last up to 2 months to 3 months as long as they're properly stored in the refrigerator.
However for the best quality and taste, the brine pickles or homemade brine pickles are best eaten within 3 to 4 weeks.
The flavor and texture of the brine pickles can change and deteriorate over time so they are best consumed within 3 to 4 weeks although they are good for around 3 months.
After 3 to 4 weeks in the fridge the "brine" in the brine pickles will often begin turning clouding and the pickles start to lose their crunch as they begin to soften up.
The brine pickles are still safe to eat during this time but they may not be as enjoyable.
The microbes that are in fermented pickles are good for you although a stray bacterium can get into the brined pickles and cause them to spoil.
If the brined pickles start to smell bad then they should be thrown out.
To make pickles safe, the key is to ensure you add enough vinegar to the cucumbers.
Clostridium botulinum can grow in canned and pickled foods that are improperly canned or pickled foods with a pH higher than 4.6.
