When processing grapes, the seeds are either discarded or transformed into grapeseed oil during winemaking. Pretty cool!
There are two methods commonly employed to accomplish this. The first method, considered more effective and popular, utilizes a chemical solvent to extract the oil from the seeds. This method takes advantage of the limited oil supply present in the seeds. The second process, known as cold or expeller pressing, involves mechanically pressing the oil out of the seeds. Although this method is more expensive, some argue that it produces a higher-quality oil due to the absence of solvent residue.
Grapeseed oil boasts a high smoke point, making it suitable for various high-temperature cooking techniques such as frying, sautéing, and baking. Unlike some other oils, grape seed oil remains stable and does not break down or generate harmful compounds when exposed to high heat.
Beyond the kitchen and its nutritional advantages, grape seed oil finds popularity in skincare. Suitable for all skin types, including dry, oily, and combination skin, grape seed oil is gentle and non-comedogenic, meaning it does not clog pores.
So, considering it comes in different forms and is intended for various uses, are there different ways you should store it? Let’s take a look.
How To Store Grapeseed Oil?
Grapeseed oil, if cold pressed, is best stored in the refrigerator as it is quite volatile to oxidation when exposed to light and heat. Grapeseed oil that has been chemically extracted is okay in a cool and dark section in the pantry. It should never be left in the sun or in warm areas near the stove, which is what a lot of households do for easy access when cooking.
As most commercial grapeseed oils are the chemical solvent kind, then your cool and dark pantry is your best friend! If you are using it for skincare, a dark cupboard in the bathroom is the easiest way to store it.
Can You Freeze Grapeseed Oil?
Indeed, this oil can be frozen, which might be a good idea if you have a large amount of the cold-pressed variety that you do not intend to use any time soon. To freeze grapeseed oil in individual portions, you can follow this step-by-step guide:
1. Pour the oil into ice cube trays, with each cube containing about two tablespoons of oil.
2. Place the tray in the freezer until the grapeseed oil is solidified.
3. Once frozen, remove each cube, place it in a labeled, sealable plastic bag or container, and store it in the freezer for up to six months.
Keep in mind that freezing oil may result in textural and visual changes, such as cloudiness.
How To Defrost Grapeseed Oil?
For thawing grapeseed oil, it is recommended to transfer a portion to the refrigerator and allow it to melt gradually. Avoid using the microwave or hot water for thawing as it may adversely impact the oil’s quality.
If you need it quickly, then thaw it at room temperature for a couple of hours. If it is individual portion sizes, it should defrost pretty soon.
How Long Does Grapeseed Oil Last?
Unopened grapeseed oil can be stored in the pantry for 3 to 6 months past its best-by date, while in the fridge, it can last for 6 to 12 months beyond the best-by date.
Once the grapeseed oil is opened, it can be kept in the pantry for up to 6 months and in the fridge for up to a year.
Whether opened or unopened, grapeseed oil can be frozen and used for up to 12 months.
How To Know When Grapeseed Oil Is Rancid?
Grapeseed oil, like any other cooking oil, is prone to spoilage and should be discarded under certain circumstances. Here are a few key indicators that it’s time to let go of your grapeseed oil:
1: Pay attention to the smell. If your grapeseed oil emits an unpleasant aroma resembling nail polish remover or old paint, chances are it has turned rancid. In fact, any “funny” or offputting smell should be a clear sign of spoilage.
2: Inspect the surface and neck of the bottle for any presence of mold or contaminants. While oils don’t naturally cultivate mold, external contamination is a thing and can cause unexpected developments! Should you notice any growth on the surface or near the bottom, it’s best to bid farewell to your grapeseed oil.
3: Another way to assess the quality of grapeseed oil is through taste. Rancid oil tends to have a sharp or bitter flavor, serving as a major indicator of spoilage. If your grapeseed oil no longer offers the mild and neutral taste it once had, it’s time to part ways.
4: When cooking with grapeseed oil, keep an eye on the taste of your prepared dishes. If cooked food carries a bitter taste or develops unexpected sharp notes, it’s possible that the oil is to blame. That’s why it’s always recommended to taste any old grapeseed oil before cooking with it.
It’s worth noting that other oils, including canola, sesame oil, and various vegetable oils, exhibit similar signs of spoilage. If anything else about your grapeseed oil seems questionable or off, trust your instincts and discard the bottle.
FAQs
It is widely advised to opt for cold-pressed grapeseed oil as it is free from chemical involvement during the processing method. A majority of grapeseed oil available in stores undergoes extraction using hexane, which is a neurotoxin. Do remember, though, that cold-pressed oil does not have the high smoke point that refined oils do.
Grapeseed oil is high in vitamin E and has a high smoke point if you need a high-heat oil for deep frying or stir-frying. This does not mean that grapeseed, particularly the commercial kind, is better for you than a cold pressed olive oil, but it does have its uses.
You sure can. Opt for pure, cold-pressed grapeseed oil, which can be used as a facial serum before bedtime. For sealing moisture into your skin, try adding a drop of grapeseed oil to your preferred moisturizing creams for both face and body. You will often see grapeseed oil as an ingredient in certain skincare products under its scientific name, Vitis Vinifera.
Grapeseed oil is derived as a byproduct of winemaking. Once grapes are pressed to produce wine, the remaining grape seeds become the source for extracting grapeseed oil. If it is cold pressed, it is all-natural, but if it is chemically extracted, then some of the solvents remain.
