Vinegar is a popular and versatile ingredient in cooking, but what exactly is it? Vinegar is an acid that’s made from fermented fruit or vegetable juice. The fermentation process produces alcohol, which then becomes acetic acid through a secondary fermentation process. It's these biochemical reactions that give vinegar its unique flavor. During the initial fermentation stages, yeast ferments sugars into alcohol while producing carbon dioxide gas as a by product.
This means that if you're making vinegar from an apple cider vinegar base, your apple cider vinegar will have hints of apple flavor. If you're making it from wine, your wine vinegars will have hints of wine flavor (and smell). Vinegars made with other alcohols like white or red wine or brandy also have unique characteristics that come from those specific beverages.
The same goes for containers: if you ferment something in wood barrels or plastic buckets, those materials will transfer their own flavors to the liquid inside them. A glass jar allows for more oxygen exposure than its ceramic counterparts—which helps keep the fermentation process going strong—but also lets more light into it as well. This can be good or bad depending on what your final product tastes like; some vintners prefer to age their wines in clear bottles so customers can see exactly what they've purchased before consuming!
The glass acts as an inert container and will not react with or absorb any of the liquid inside. It also doesn't allow anything else to get into the bottle, so it won't spoil either. Because vinegar is made from fermented foods like apples, grape juice and wine, there are often still some remnants of those items left behind in the finished product that could cause problems if they were exposed to air for too long. This can lead to mold growing on top of your vinegar if you leave it out too long after opening it up (which isn't good!).
The glass bottle is one of the most important parts of your vinegar purchase. Why? Because it protects the vinegar inside.
You might think that a bottle made out of glass is sturdy enough to withstand anything, but it's not as tough as you might think: when dropped, even on hard surfaces like concrete or wood, there’s still a chance it can break. If this happens and your vinegar becomes contaminated with foreign substances (like water), it can't be sold or used for food purposes—and without those two things happening, the bottle is effectively useless!
Vinegar can be a great alternative, but it is not the same as bleach or soap and water. Use vinegar sparingly on non-reactive surfaces, because too much can strip waxes off of your floor or leave behind a residue that looks like soap scum when it dries up.
On the other hand, if you want to use vinegar somewhere that isn't an acid-loving material (such as marble), then go ahead! Just remember: no matter what kind of thing you're trying to clean with vinegar, just make sure that the vinegar itself isn't wet before putting it away after use (unless the label says otherwise).
As you can see from this blog, glass bottles are best for storing vinegar because they preserve the quality of the product inside.
