why olive oil be in a clear bottle?

The requirement for olive oil to be stored in a clear bottle is actually a matter of preference and marketing strategy. While brown glass bottles are commonly used to protect light-sensitive products, such as pharmaceuticals and certain beverages, clear glass bottles are often chosen for olive oil to showcase its natural, vibrant color and clarity.

To mitigate this, manufacturers often take measures to the clear bottles from light, such as using UV filters or providing secondary packaging like boxes or dark-colored wrappers.
In summary, although brown bottles are commonly used to protect light-sensitive products, the choice to package olive oil glass bottle in clear glass bottles is mainly driven by aesthetic considerations and the desire to showcase the natural color and quality of the oil.
