    Pretty sure they will say refriegerate affer opening somewhere on the bottle. They slap that on pickled or high acidity condiments that probably don’t need refridgeration for safety reasons.

    I have no idea if it is necessary, if it extends the shelf life, or has no purpose other than making it more likely for people to throw it out if they don’t put it in the fridge.

    I put it in the fridge if it says to assuming it might keep it fresh longer. But if I leave something pickled out overnight I will just put it back in the fridge.

    I would. While pickling is a good way to preserve food, the food itself needs to stay submerged in the pickling solution if not refrigerated. Acids used in pickling solutions are extremely hostile environments for bacteria.

    Big caveat: Pickling and fermentation processes can be very different. One process may work to keep food safe for years, but others may only last weeks or days once the food is exposed to air.

    Refrigeration slows down bacterial growth enough for days or weeks of storage, but eventually, robust bacteria will take over if there is just a little bit of air circulation. Warmer conditions with occasional air circulation and some kind of food source just increases the risk of bacteria development exponentially.

    Before refrigeration was a thing, picking or salt packing was king. It works well, but it’s easy to screw up. Heck, I think authentic/traditional kimchi production never uses refrigeration and relies on the acids as well as CO2 and basic ethanol production to stay sterile safe.

    These days, just throw everything in the fridge. It’s easier and safer because you don’t know exactly what preserving processes were used.

      The packaging also offers some hints. It has a glass jar and a metal lid, which might click when you open it. My guess is, that bottle went through an oven before being shipped. Glass is heavy and expensive, which isn’t what the manufacturer wants. They wouldn’t use a package like this unless they really have to, which implies heat treatment.

      If sterilized properly, that process killed all the microbes in it, which means you can safely ship it and store it in ambient temperatures for a very long time. Chemical reactions still take place, which might affect the taste if you store it for decades or centuries. However, if it’s properly sterilized, microbes aren’t involved in any of it. Once the lid is opened for the first time, airborne microbes immediately contaminate the contents and the clock starts ticking.

      Salt and vinegar make the environment hostile for most microbes, but not all. This method will clearly help with limiting the growth rate, but keeping the jar in the fridge would be my advice as well. This way, you get the benefits of multiple methods of slowing down the growth rate.

    Your question is answered, but I just wanted to say; good on you for being food preservation conscious. When I first started dating my now wife she thought that you needed to store syrup in the refrigerator, and things like mayonnaise and unwaxed cheese could sit in the open. I had to go through her whole pantry 🤢

      My partner’s family from Philippines grew up in a home without appliances like refrigerators, like many, many people in developing countries.

      So while now they have every modern convenience, old habits die hard and stomachs seem to adapt to even the most adverse conditions of foodstuffs.

      Not mine. I love their cooking but can only eat food that I’ve seen opened or cooked in front of me. They will legitimately leave meat dishes out on the table for two days or more and then simply “reheat” and consider it good to serve. The cabinets are full of things like mayo, cheese dips, opened gravies and open bottles of fruit juice.

      I have had some of the very worst food poisoning in my life from inadvertently eating something there like chicken salad that I thought was fresh, but made with hard-boiled eggs that had been sitting on a counter in summer heat for several days that a “friend” brought over so they “wouldn’t waste.”

      Of course I’m the only one that gets sick, so I’m the “special one” that everyone now thinks has some terminal illness and treats me like a hospice patient.

      Yikes, I am not sure I have found a bottle like this that doesn’t say, “Refrigerate after opening” on the side of it was required. I assumed it was a FDA rule, never looked into it.

        Some syrups do require that, yes. The 100% natural syrups absolutely do require refrigeration, but the ones with preservatives do not need to be refrigerated. And just to be clear, I make a dish that requires syrup an estimated 2 weeks

    Pickling is one way to preserve food, but refrigeration is better.

    Yes. You can keep them out, but they will last less and may grow mold depending on the storage and handling conditions.

    It usually says this on the label, at least in my country it has a phrase like “Store refrigerated after opening and consume within a few days”.

    If it has no instructions or you are unsure, I’d default to yes, put them in the fridge after opening.

    Yes. They are sterilized when packaged and are ready to be colonized once open. If they were live fermented and still live, you’d be ok as long as they remain below the brine.

    Id say they’ll be pretty safe out of the fridge, but if you keep them in the fridge they might stay firmer longer. Like more bite. They might go mushy in the cupboard.

    Typically the label should answer your question. However from experience, I will say yes.

    Ideally, if you can and know when you will use it, refrigerate them already before you open any jar, this reduces the time window when bacteria or molds can grow.
