Which is an advantage of glass bottles?

• A. Inert, impermeable to O2, sterile, inexpensive, recyclable
• B. Heavy, fragile, rigid (rapid oxidation once opened), contents can suffer from light strike
• C. Requires specialized filling equipment
• D. Not recyclable

Answer: (A)

Glass bottles are advantageous because they are chemically inert and non-porous, so they don’t react with beverages and protect contents from oxygen ingress. This barrier helps preserve flavor and freshness, and the container can be sterilized to maintain hygiene. Glass also does not impart flavors or odors to the drink, which is important for personality and quality. In addition, glass is widely recyclable, making it an environmentally favorable option when reuse and recycling streams are available. While other packaging options may be heavier, more fragile, or susceptible to light exposure or oxidation if not designed properly, the combination of stability, hygiene, and recyclability makes glass bottles a strong choice for beverage storage.
