Olive should keep a minimum of 15 months if it is properly stored. If it is stored in its original container and remains unopened, it should last for 2 years or more.
Olive oil has the best flavor when it is used within a year after it is pressed and it is at its peak within 2 or 3 months after pressing. Unlike many types of wine, olive oil does not improve with age. As olive oil ages, it continually degrades and the acidity level rises. As a result, an older bottle of olive oil may have an unpleasant odor and taste. The oil will be neither harmful if consumed, nor very pleasing.
يعنى بإختصار أن زيت الزيتون لا يعيش....فى أقصى الحالات لأكثر من عامين و، و بعد ذلك يبدأ فى التحلل و التأكسد....و إن كان لا خطر من تناوله فى هذه الحالة...إلا أن طعمه و رائحته لا يكونان مقبولين.....فزيت الزيتون ليس كا خمر...كلما تعتق ، صار أفضل.....هذا مذكور بالنص للرد على كلامك!

emember - Olives are fruit; olive oil is a fruit juice. Air, heat, and light will cause olive oil to turn rancid (rancid is the flavor which is imparted in an oil after it has undergone the process of oxidation. Since prolonged contact with oxygen is the rot cause of oxidation, rancidity is a common defect, so it should be stored in a cool place in an airtight container). If your oil has a buttery taste, then it's probably rancid.
Store at a temperature of 14 degrees C. or 57 degrees F. If you have a wine cellar, store your olive oils there and keep a small amount in your kitchen. Do not put olive oil in a container without a tight cap.
When chilled, or in cold weather, the oil may turn cloudy and even solidify. Such oil will clear again as it warms, so cloudiness should not be taken as an indication that the oil is part its prime. Be sure bottles are tightly sealed. Olive oil can be refrigerated but doing so will cause it to congeal and turn cloudy, but should not affect flavor. If refrigerated, olive oil will return to its original, liquid state when warmed to room temperature again.
Tinted glass, porcelain, or stainless steel are the best materials for containers; oil should never be stored in plastic or in reactive ****ls. Stay away from plastic containers as the oil can absorb PVCs.
هل كان الآباء الأولون يحتفظون بالزيت فى آنية مُغلقة بإحكام و مصنوعة من البورسلين ، الزجاج، أو الحديد الغير قابل للصدأ.....إذن فالزيت فاسد يا صديقى...و أنظر إلى الحلة التى يُحضر فيها أباك الزيت العظيم ، فى مُداخلة الأخ البتار.....فهى حلة من النحاس أو الألمونيوم....يعنى تتفاعل مع هذا الزيت!!!

Extra virgin olive oils are best consumed young as it is at this time when their fresh olive like aromas and flavours are at their peak. Unlike wine, they do not mature with age, so the closer to their release date that you purchase and use them, the better. However, the higher levels of natural antioxidants and the higher proportion of monounsaturated fats generally found in extra virgin olive oil mean that they generally remain fresher longer than other edible oils.
Once a bottle is opened oxygen in the air will hasten the deterioration of the oil and the oil should be consumed quickly. It is therefore advantageous to buy oil in small bottles or in casks. But as a guide, provided they are stored properly, the majority of extra virgin olive oils will retain good flavour, aroma and freshness for at least 12 months. By that time, new season oils will be on the market for you to try.
يُنصح بإستعمال زيت الزيتون النقى فى خلال 12 شهر من تاريخ إنتاجه!
