What is the shelf life of Eden oils and do they need to be refrigerated after opening?
Eden oils have a shelf life of 3 years from the date of production. They are bottled in amber glass for protection from light. Our oils do not require refrigeration, but it will not hurt them if you do. The only exception is olive oil, which we recommend storing in a cool, dark place. If olive oil is refrigerated, it will solidify. When removed from the refrigerator and allowed to liquefy at room temperature, condensation can form.
Why does Eden use amber glass bottles for bottling oils and vinegars?
Amber glass bottles work best to protect the products nutrients, flavor, color, and value from the damaging effects that light has (photo oxidation). Fluorescent lighting, in particular, affects food quality with its light rays. This is especially problematic in the retail food store.
Is Eden Ume Plum Vinegar really vinegar?
No. Eden Ume Plum Vinegar is the pickling brine from making pickled umeboshi plums with shiso leaves (beefsteak) and sea salt. It gets its ruby red color, naturally, from red shiso leaves. In Japan, it is used just like real vinegar in making homemade pickles, salad dressings, marinades, sauces and for seasoning vegetables and soups. Since it is salty, unlike 'true' vinegar, you may need to reduce or eliminate the amount of salt called for in recipes.
Are 'expeller pressed' and 'cold pressed' oils the same?
No. Mechanical 'expeller' pressing and 'cold' pressing are two different processes used in making unrefined, naturally produced oil. Mechanical expeller pressing applies pressure to the seed or nut by use of rollers to expel the oil. The rolling action and pressure generates some heat through friction, but the temperatures are low enough to protect the nutritional integrity, flavor, and aroma of the oil seed. Expeller pressing is the most common method used in extracting seed and nut oils.
Olive oil is unique in that it is the only oil that can truly be considered 'cold' pressed. Cold press extraction is a simple, gentle pressing that doesn't heat the oil much above room temperature. Oil received from the first pressing of the olives is called 'virgin' olive oil, which comes in three grades: Extra Virgin (the best) has the perfect flavor and aroma. All Eden Oils are expeller pressed with the exception of Eden Extra Virgin Olive Oil, which is 'cold' pressed, and is the first pressing of the olives.
