Amber bottles offer a protection against light wavelengths within the 10 nm to 400 nm range. This is the ideal spectrum to protect against UV light radiation, which is why many pharmaceutical and beverage manufacturers choose amber bottles. They are also typically a little more expensive than amber or flint bottles.

Amber bottles can be used to store oil to avoid deterioration and protect the aromatic and therapeutic properties of your essential oils. Dark glass such as amber or cobalt helps to keep out deteriorating sunlight. It is best not to store essential oils in clear glass bottles.
