Liquor bottles are made from glass because it is an inert material that does not absorb or impart flavors. Plastic, on the other hand, can impart flavors on liquor and even change its appearance if left in contact for too long. It is also easier to recycle a glass bottle than it would be to recycle a plastic one.
Light can cause a chemical reaction in alcohol, which results in oxidation. In wine this is referred to as "vinification" or bottling. The taste changes from that point forward, so it's important not to store wines long term in clear or green glass containers that let light in easily.
Light also causes alcohol content to evaporate over time, especially when exposed to sunlight. This is why some liquors are stored in darker colors; they absorb more light than others and protect against evaporation better than clear ones do (e.g., brown bottles).
You might be surprised to learn that the plastic bottles you drink out of are often made from corn. Corn is cheap, and it's a common ingredient in just about every kind of plastic bottle you can buy.
Why does this matter? Because as we all know, corn can impart an unpleasant flavor to liquor. When distillers were making their own bottles, they could control exactly what went into the process from start to finish—including how the bottles were made. Today's distillers don't have that luxury; instead, they must rely on outside suppliers for their packaging materials. And those suppliers don't always use the highest quality ingredients possible because those ingredients cost more money!
There are different reasons why liquor bottles are made of glass, but one major reason is that some liquors are sensitive to plastic.
The main concern is the effects of UV light on the flavor and color of your drink. During a long period of time, UV rays can break down the alcohol and make it taste bad or change its color (for example, pink gin turns brownish after sitting in sunlight for a few days). Plastic containers don't block out as much light as glass does; therefore, they're not ideal for storing liquids meant to be kept cool and dark for extended periods of time—especially liquors like whiskey or rum that have a lot of natural sugars that can turn into vinegar if exposed to air too long.
Glass is made out of sand, which is a natural resource that can be replenished. Plastic is made from oil, which is a non-renewable resource that will eventually run out. Glass can be recycled over and over again whereas plastic bottles can only be recycled a few times before they become unusable.
In conclusion, there are a few reasons why liquors are stored in glass bottles. The first being that plastic is not as strong as glass, and therefore this material can be easily broken if dropped on the floor. Also, most liquor bottles are made from recycled materials because they don’t contain any toxins or chemicals that could be harmful to humans and animals alike; however some do not have any recycling options at all so it is always better safe than sorry when deciding what type of material works best for your needs! Lastly, some people prefer storing their liquor in plastic containers because they don’t want anything ever touching their precious alcohol other than themselves when pouring out drinks; however those people should keep in mind these facts before making their final decision on which type of container will work best for what kind of person."
