Castillo de Piñar Olive Oil Bottles
Less Light for Longer Shelf Life
This unique violet glass bottle is similar in composition to that of a violet amethyst. Our bottle preserves the olive oil's organoleptic properties, providing natural protection for a longer shelf life. Other conventional packaging materials do not offer sufficient protection. Most plastics are porous, exposing their contents to oxidation and in some cases even influence taste. Also amber, green or clear glass bottles do not shield light-sensitive contents sufficiently.
Storage Test with Tomatoes
A microbiological experiment was conducted with cherry tomatoes. During this test, two cherry tomatoes were stored for 7 months - one in a white glass container and one in a violet glass container. They were kept at room temperature near a window where sunlight could reach both bottles equally. After 7 months, the cherry tomato stored in ultra violet glass showed no loss of color and no signs of drying out, while the microbiological changes of the tomato stored in white glass can be clearly seen.
Storage Test with Chives
White, green and brown glass bottles are permeable in the visible light spectrum and don’t offer enough protection against the decomposition caused by light. As an experiment, several herbs and spices were stored for 3 months in several types of glass (white, brown, violet), and were either exposed to the sun for several hours a day or kept inside.
After 2 months, the visible quality change was recorded with photographs, and the difference in smell determined in a blind test with volunteers. The illustration shows clearly that the chive samples that were exposed to the sun have bleached in brown and white glass. As photographed in this illustration, the sample stored in violet glass shows no color change. The smell of the chives stored in violet glass was also clearly stronger and fresher.
Bio-Secure Cap System
Another exclusive feature we offer is a secure, tamper-proof spout which also improves the flow of the oil from the bottle.
