Glass is a great material for packaging wine. It's nonreactive, it doesn't impart flavors and tastes to the wine, and it provides excellent protection from light. Glass bottles can also easily be labeled with things like vintage year and bottle size. In addition, glass bottles provide a good seal when they're capped with corks or screw tops made of metal or plastic—and these days most wines are sold in sealed containers (not just bottled). Why do wine suppliers still use glass bottles?
Glass is nonreactive.
Most wine bottles are made of glass, and this is one of the reasons why. Glass is nonreactive, meaning that it doesn't react with anything in or around it. It's inert, which means that it won't react with other substances in your wine bottle when you open it up later on. Since glass is also nonporous and non-leaching (meaning nothing will pass through its surface), you can rest assured that chemical compounds in your wine will not be affected by any kind of interaction with the container itself—and vice versa!
And because glass isn’t toxic or allergenic at all (like some plastics can be), there aren't any health risks associated with using a glass container as an alternative to aluminum cans or PET bottles. Plus: no worries about corrosion from acidic liquids like soda pop!
Finally, because all types of glasses are polar—or electrically charged—they won't trap any ions inside them after washing away traces left behind by fermentation agents such as sugarcane juice; this means they're safe for use over long periods without breaking down under pressure from constant exposure to air molecules within their environment."
The materials must be available to the bottler at a reasonable cost.
The most common material for wine bottles is glass. Glass is easy to make, and it's easy to get the raw materials. It's a great material for packaging because glass is very durable, nonreactive, easy to clean and recycle.
Glass bottles don't impart flavors and tastes to the wine.
If you've ever had wine in a plastic cup, or even a paper bag, you may have noticed that the taste of the wine changes. This is because plastics and other synthetic materials are reactive with wine and can leach off flavors that they've absorbed from their surroundings. (Think of how a plastic water bottle will take on a plastic-y smell after a while.) Glass is nonreactive—it doesn't change the way it works just because it's holding something else!
In addition to being inert, glass also doesn't impart any flavor or taste onto your favorite beverage. Unlike metal cans (which come with their own metallic tinge), glass bottles don't add anything unwanted to your drink—and since aluminum cans aren't considered safe for long-term storage of alcoholic beverages due to health concerns about heavy metals like aluminum seeping into liquids over time, this can be an important consideration when choosing what kind of container you prefer for your favorite tipple!
Of course there are many other reasons why winemakers choose glass bottles over other forms such as jugs: they're easy to clean, refillable (or recyclable), lightweight yet durable enough not break easily if dropped on accident--the list goes on and on! But these three main points should give some insight into why this classic choice has remained popular since ancient times."
Glass bottles protect the wine from light.
Light can affect the color and taste of wine. It’s also a big reason why most wine is put in glass bottles.
Light can damage wines by causing oxidation, which changes the flavor and smell of wine. If you hold an open bottle up to light for too long, you might notice that it starts to look like an orange or brown liquid – this is because the tannins (a natural preservative) in your alcohol have oxidized due to exposure to sunlight or fluorescent light bulbs.
Glass bottles provide a good seal.
The fact that glass is airtight, impermeable to oxygen, impermeable to light and impermeable to bacteria is a huge benefit for wine.
Wine bottles can be stored for long periods of time without losing their quality. The wine inside a glass bottle will not deteriorate as it does in an aluminum can or a plastic bottle.
Because they are airtight and impermeable to oxygen, the cork used on most wine bottles doesn't dry out and lose its ability to seal over time as it would if exposed to air during storage.
Glass bottles do not impart any off flavors into the wines they contain because they don't allow anything else into them either. This means that there's no worry about chemicals leaching from the plastic or metal containers used in some wines packaging because they never actually come into contact with the liquid itself!
Glass bottles allow the buyer to see what they're buying before they open it.
Here are some of the advantages
- You can see what you're buying. With wine bottles, you can see the color and clarity of your wine before you open it. Bottle shape can also help you identify what kind of wine it is—for example, Bordeaux bottles are wide at their base and taper toward their neck, while Burgundy bottles are tall and slim.
- You know how much sediment to expect in your bottle of reds. Some rosés (which can be made from white or red grapes) have a delicate blush color caused by tiny particles left behind as they ferment; otheres have more pronounced sediment due to non-traditional fermentation techniques like enological reduction or extended maceration periods
Glass is just a great material for wine packaging
Glass is just a great material for wine packaging. It’s inert, which means it doesn’t react with or absorb anything from the wine inside it. This is why you don’t have to worry about plastic bottles spoiling your wine after opening them up—the oxygen and light exposure will still turn your favorite Cabernet into vinegar without a glass barrier between it and those two destructive elements.
Glass bottles are also easy to clean and sanitize, which is key when you consider how many hands touch them during the winemaking process, especially considering all the natural yeast in the air that would otherwise end up on those same surfaces if they were made of something else like cardboard or tin (which aren't bad materials at all).
Glass bottles are also easy to recycle because their shape makes them very efficient at holding air bubbles, thus making them lighter than similarly-sized plastics or metals despite being heavier than plastic alone (this is what makes glass so attractive as packaging material). Glass can then be melted down into new containers instead of being thrown out entirely like other types of disposable packaging would require us to do after use (which not only saves money but also reduces our carbon footprint!). Plus recycling glass doesn't produce any toxic fumes during production either!
We hope you now have a better understanding of why glass bottles are so important in the wine industry.
