How do I know if the product is still good?
What is the product's shelf life?

Napa Valley Naturals products have a "Best By" date and lot number printed in ink on the glass bottle about an inch from the bottom of the bottle. The date is read month/day/year. Olive oil and grapeseed oil will both maintain their freshness longer if stored in a cool, dark place. Storage in the refrigerator is not recommend. Olive oil may become cloudy and solid and may combine with condensation from the refrigerator. This condensation could negatively affect the taste of the olive oil.

Why is my olive oil cloudy and thick?

Cool temperatures can cause the waxy esters in extra virgin olive oil to solidify. This often happens in the winter, in cool stores or after refrigeration. To return the olive oil to its clear state, warm a pan of water and set the bottle in the pan or leave the olive oil at room temperature.

Should extra virgin olive oil solidify in the refrigerator (a.k.a. The Refrigerator Test)?

The short answer is that some will and some won't. While it would be a convenient and easy test if it were accurate, the refrigerator test is not accurate. The temperature at which an extra virgin olive oil will solidify varies with the ripeness and the varietal of the olive. The only objective test to determine extra virgin olive oil's chemistry as in fact extra virgin is done in a lab.

Why does my olive oil have dark sediment at the bottom of the bottle?

Dark brown residue is likely pieces of the fruit of the olive in the oil. Napa Valley Naturals extra virgin olive oils are unfiltered so tiny pieces of the fruit of the olive often end up at the bottom of bottles since they are heavier than the oil. If the oil doesn't smell rancid or taste bad, then it's likely not a problem. Sediment is natural and normal in 100% unfiltered olive oils like Napa Valley Naturals. It tends to look like very dark oil at the bottom of bottles. Shake up the bottle and see if it dissipates.

Do your products share processing equipment with other products?

Napa Valley Naturals is bottled in a facility that also handles soy, peanut and nut products.

At what temperature are Napa Valley Naturals Extra Virgin Olive Oils pressed?

Napa Valley Natural Extra Virgin Olive Oils are pressed at temperatures below 98.5 degrees. Our olive oils are pressed at such low temperatures to preserve their flavor and nutritional value.

What is the acidity of Napa Valley Naturals Extra Virgin Olive Oils?

Napa Valley Natural Extra Virgin Olive Oils have an acidity of .5% or less at the time of bottling. Acidity and quality can be affected by many factors once the olive oil leaves our bottling facility. Temperature and direct bright light during transportation and storage on store shelves can negatively impact the quality of olive oil.

How do I know if my olive oil has gone bad or rancid?

A stale or "off" odor is a sign of rancid oil. However, a pungent, peppery or spicy taste or smell is an attribute of high quality, unrefined extra virgin olive oil.

If you are certain that your Napa Valley Naturals olive oil is rancid, please email us at info@napavalleynaturals.com with the lot number, Best By date, type of product and size, your mailing address, telephone number, the store at which you purchased the product and date if known, and we will resolve any concerns that you may have.

How do I use Grapeseed oil?

Napa Valley Naturals Grapeseed Oil is versatile cooking oil. It can be used in salad dressings when a flavorful olive oil might overpower the recipe. And its high smoke point make it an ideal choice for frying or sautéing when olive oil might brown and burn.

How should I store the product?

Olive oil and grape seed oil will both maintain their freshness longer if stored in a cool, dark place. Storage in the refrigerator is not recommend. Olive oil may become cloudy and solid and may combine with condensation from the refrigerator. This condensation could negatively affect the taste of the olive oil. Vinegar can be stored in the refrigerator or in the pantry or cupboard.

What is the glob in my vinegar?

Napa Valley Naturals vinegars are unpasteurized, so you may find pieces of the "mother" of the vinegar in the bottle. They appear to be globs, strands or sediment in the bottle. They are the harmless bacteria, acetobacter, which turns wine into vinegar. The mother is a naturally occurring part of the vinegar making process.

Are there sulfites in Napa Valley Naturals Organic vinegars?

There are naturally occurring sulfites in our organic vinegars. We do not add sulfites.
