The exact storage conditions and shelf life are always stated on the packaging of the specific batch, and these should be your first point of reference. Below is general practice for handling unrefined oils, to which this product also belongs.
The unrefined component that helps preserve the pronounced flavour and aroma also makes the oil more sensitive to external factors. Flavour and freshness are usually affected by:
- light — the oil is best kept in a dark place or in an opaque container;
- heat — a cool place helps preserve the aroma for longer;
- contact with air — the bottle should be closed tightly after each use.
Since the product is used in small portions, 100 ml lasts a long time, so careful storage is particularly appropriate. After opening, the oil is kept tightly closed and used within 3 months; if the taste or smell has noticeably changed before then, it should not be used. This approach helps preserve for longer the very berry note for which the oil is added to dishes.
