Olive Oil & Vinegar Facts
Could something in your kitchen cabinet help you lose weight and prevent cancer? It’s something many people don’t associate with weight loss or even health.
Some refer to this weight loss food as “liquid gold” because of its color and the fact that it’s rich in nutrients. A local research dietitian swears by this particular ingredient and has done local studies on its power to help us lose weight and prevent prostate and breast cancers. And here’s the irony: It’s high in fat.
If you want to trim your waistline, try consuming at least three tablespoons a day of extra virgin olive oil. Mary Flynn, a registered dietitian and researcher at The Miriam Hospital, has the proof to back it up. She recently completed two weight loss studies. One looked at an olive oil plant-based diet to prevent breast cancer; the other to see if that same diet could prevent prostate cancer.
“What we were looking at was when men are treated for recurrent prostate cancer, they’re treated very often with a therapy that blocks the testosterone. And when this happened it increased their risk factors for heart disease by increasing the metabolic syndrome, which is a large waist, an increase in the triglycerides, decrease in HDL, the blood pressure goes up and glucose goes up,” Flynn said.
In all, 18 men took part in the plant-based olive oil diet. “I asked them to use at least three tablespoons a day, which I put as part of the meal plan and the recipes and then it focuses mainly on vegetables,” Flynn said. Vegetables in this Mediterranean-like diet are unlimited. Fruits are limited to about three servings a day, and whole grains are emphasized.
“The beauty of the diet is the volume is large. So, your stomach is full and then you have the fat, the olive oil being used to prep the meal so you don’t get hungry between the meals. And so I see snacking go down,” Flynn said. Flynn found in this hospital-funded study that men not only lost weight, they embraced the new way of eating.
She already knew women were benefiting. It’s what led to her publishing this book, “The Pink Ribbon Diet,” which was borne out of an earlier study of 44 overweight women diagnosed with invasive breast cancer. In that study, women who followed the plant-based olive oil plan lost weight and lowered their triglycerides — a type of fat found in the blood — and raised their good cholesterol.
Despite its name, the book is for anyone trying to lower their weight and risk for disease. “It’s mainly a cookbook. It gives the rationale for why I choose the foods that I do, I think, as well as 150 very easy recipes,” Flynn said.
The olive oil diet used in Flynn’s studies includes at least those three tablespoons of olive oil a day and a lot of vegetables. Red meat was not allowed, but limited amounts of poultry and fish were.

Traditional Balsamic Vinegar of Modena (Italy) is made from white and sugary Trebbiano grapes grown on the hills around Modena. Custom demands that the grapes are harvested as late as possible to take advantage of the warmth that nature provides there. This vinegar is made from the cooked “grape must” [the juice pressed from grapes before it has fermented; new wine] matured by a long and slow vinegarization process through natural fermentation, followed by progressive concentration by aging in a series of casks made from different types of wood and without the addition of spices or flavorings. The production of traditional Balsamic Vinegar is labor intensive and time consuming; this accounts for its high cost and limited availability.
Production of traditional Balsamic Vinegar is governed by Italian law and provides that a specific Certification Agency (Cermet) oversees all production phases, from the vineyard to the bottle. All of the product that is bottled must pass a sensory examination run by a panel of five tasting judges.
Commercial grade Balsamic Vinegar of Modena constitutes a more economical alternative to the traditional product. In the United States, products are also allowed to be labeled as Balsamic Vinegar, based on the U.S. labeling laws. These products are made from the juice of grapes, but would not carry the term “of Modena” on the label. Traditional Balsamic Vinegar of Modena generally is found in specialty stores. Commercial grade Balsamic Vinegar of Modena can be found in specialty stores, supermarkets, and supercenters.Commercial products are of high quality and suitable for use in marinades, vinaigrette dressings, and in making pan sauces.
The product has a long shelf life and can be stored in a closed container indefinitely. Store the product at 4-30°C (39-86°F), but refrigeration is not required. Exposure to air will not harm the product, but may cause “mothering,” which causes the solids to filter out. Some sedimentation is normal for a product that contains a high level of soluble solids, but the sedimentation will disappear when the bottle is shaken.
Traditional Balsamic Vinegar of Modena is only bottled in the distinct, bulb-shaped bottle of 100 ml. It has either a white cap (minimum age of 12 years) or gold cap (minimum age of 20 years).
Salad dressings, sauces, and gravies benefit from the addition of Balsamic Vinegar. Sprinkle on cooked meat to add flavor and aroma; season salad greens, strawberries, peaches and melons; or use as an ingredient in your favorite salad dressing.

All olive oil starts with fruit on a tree. What happens after the fruit and the tree part company makes all the difference to the oil produced.
United States Department of Agriculture the only acceptable grade of olive oil is Virgin Olive Oil per the US Department of Agricultue. The Food and Drug Administration definition is, “Olive oil is the edible oil expressed from the sound, mature fruit of the olive tree.” No recognition is given to refined or extracted oil.
The two ways to assess virgin olive are chemical and organoleptic analysis. They are both equally important although one is totally objective and the other is totally subjective. Laboratory analysis informs us of the levels of beneficial polyphenols and oleic acid, and the products of deterioration free fatty acids and peroxide. But it cannot indicate anything about the pleasure of using fresh, well produced oil.
Organoleptic analysis happens in the nose and mouth of the taster, either professional or with you, our customer. Aesthetic notes of fruity, nutty, fresh grassy, peppery, and many, many others are there in varying balance that give complexity to the oil and appeal in different ways to each person. Laboratory analysis can track down the chemical nature of those flavors and aromas, but the human sensory system is still the best organoleptic analysis device. We recommend that you give yourself the opportunity to taste and assess many olive oils in order to educate your palate and help you find the oil that gives you the most satisfaction.
Most grading is based on the method of production and designations are a marketing tool used by producers. The terms can be confusing and sometimes intentionally misleading. Once again it is important to know as much as possible about what you choose.
Extra-virgin olive oil comes from virgin oil production only, contains no more than 0.8% acidity, and is judged to have a superior taste. Extra Virgin olive oil accounts for less than 10% of oil in many producing countries.
Virgin olive oil is produced by the use of physical means and no chemical treatment, has an acidity less than 2%, and is judged to have a good taste. Over 50% of the oil produced in the Mediterranean area is of such poor quality that it must be refined to produce an edible product.
After these two grades come the blends of oil that are primarily refined oil and virgin Olive oil.
Pure olive oil.
Oils labeled as Pure olive oil or Olive oil are usually a blend of refined and virgin production oil. Remember, over 50% of the oil produced in the Mediterranean area is of such poor quality that it must be refined to produce an edible product. No solvents used to extract the oil but it has been refined with the use of charcoal and other chemical and physical filters
Olive oil is a blend of virgin and refined production oil, of no more than 1.5% acidity, and lacks a strong flavor.
Olive-pomace oil is refined pomace olive production oil possibly blended with some virgin production oil. It is fit for consumption, but may not be described simply as olive oil. Olive-pomace oil is rarely sold at retail; it is often used for certain kinds of cooking in restaurants.
Refined olive oil is the olive oil obtained from virgin olive oils by refining methods which do not lead to alterations in the initial glyceridic structure. It has a free acidity, expressed as oleic acid, of not more than 0.3 grams per 100 grams (0.3%) and its other characteristics correspond to those fixed for this category in this standard. This is obtained by refining virgin olive oils which have a high acidity level and/or organoleptic defects which are eliminated after refining. Just like Pure Olive Oil and Virgin Olive Oil, over 50% of the oil produced in the Mediterranean must be refined to produce an edible product. Although no solvents have been used to extract the oil, it has been refined with the use of charcoal and other chemical and physical filters. An obsolete equivalent is “pure olive oil”
Pomace olive oil is extracted from the pomace using chemical solvents, mostly hexane, and by heat. Sometimes blended with some virgin production oil. It is fit for consumption, but may not be described simply as olive oil. Olive-pomace oil is rarely sold at retail; it is often used for certain kinds of cooking in restaurants.
Lampante oil is not suitable as food because it is made usually from olives that are spoiled or insect infested.; the term lampante comes from olive oil’s long-standing use in oil-burning lamps. Lampante oil is mostly used in the industrial market. It must be chemically refined before it can be consumed. The resulting oil, after refining, is known as A-Refined, or Refined-A olive oil. It is not, strictly speaking, “olive oil.” It is used as the primary ingredient for a new product that is sold as “Pure Olive Oil.”.
As the United States is not a member, the IOOC retail grades have no legal meaning in that country; terms such as “extra virgin” may be used without legal restrictions.
Since 1948 the U.S. Department of Agriculture (USDA)has listed four grades of olive oil based on acidity, absence of defects, odor and flavor:
U.S. Grade A or U.S. Fancy possesses a free fatty acid content of not more than 1.4% and is “free from defects”;
U.S. Grade B or U.S. Choice possesses a free fatty acid content of not more than 2.5% and is “reasonably free from defects”;
U.S. Grade C or U.S. Standard possesses a free fatty acid content of not more than 3.0% and is “fairly free from defects”;
U.S. Grade D or U.S. Substandard possesses a free fatty acid content greater than 3.0% and “fails to meet the requirements of U.S. Grade C”.
With these diverse labeling styles and the small amount of information they provide, the best indicator of a good olive oil is obtained by tasting while keeping in mind the freshness and beneficial nutritional and antioxidant levels.
The most critical decision and least understood variable in producing fine olive oil is the level of ripeness of the fruit when the olives are harvested, affecting both yield and organoleptic characteristics. Additional factors of regional variations are harvest time, risk of frost and mill schedules. These all affect the quality of the finished product.
Theoretically, there exists an exact moment when ripeness and acidity levels are at their respective optimums. Crushing the fruit before this imaginary “moment” or peak of ripeness will translate to a lower yield and greener tasting oil. “Grassy” or greener tasting oil is the result of higher levels of chlorophyll still held in the fruit. Crushing the fruit before it is ripe does provide one major benefit: the acidity levels are much lower in unripe fruit. Since the primary chemical test for grading olive oil focuses on the acidity level, this early harvest oil is sometimes cynically referred to as the “virgin maker.” The lower yield, and bitter tasting aspects resulting from crushing olives before they are ripe can be offset by using this oil as a blending agent that serves to lower the acidity levels of oils that might not otherwise meet the chemical standard. Early harvest olive oil can also provide a semblance or note of freshness to oils.
Crushing olives that are overripe will produce olive oil that is smoother and softer in its inherent intensity and sought after fruity characteristics. The practice of letting the fruit become overripe on the tree has the significant economic benefit to the crusher of increasing the overall ratio and yield of oil to olive by weight. This also lowers the cost of the oil. The acidity level (free fatty acids or FFA’s) rises as the fruit begins to decompose, increasing until it is unfit for human consumption. until it is refined, which is why there is so much refined olive oil produced.
Farmers who let their olives become overripe on the tree are rewarded economically by a very high yield. The difference in yield from early harvest oil (12% to 16% oil to olives) and late harvest yield (20% to 28%) is significant and increases in yield between 33% and 133% can be achieved. Today the world market price that separates refined olive oil from extra virgin olive oil is less than 12%.
The competing interests of yield, acidity level, and flavor profile created when the olive is crushed become the most important considerations when it comes to producing high quality extra virgin olive oil. If the fruit is crushed before it is ripe it will be excessively expensive and the oil will have a bitter less fruity chlorophyll taste. If the fruit is allowed to become too ripe then it will be unfit for consumption unless it is first refined. When either consideration of higher yield or lower acidity level becomes too dominant the cost and quality of the oil suffer. It seems fitting that a balanced approach is the most rewarding one.
The basic procedure making olive oil has remained the same for thousands of years: harvest at the right time, crush the olives into a paste, separate solids from liquid components, and further separate the vegetable water from the oil. Extraction methods have a direct effect on the flavor and quality of the olive oil.
The stone grinding and matt pressing method is still used but has the drawback of intensive labor and lower yield compared to modern methods. Olives are crushed to paste between revolving millstones and the paste is then spread on woven mats, stacked in a press and squeezed until the fluid component is recovered in basins underneath the press. The vegetable water sinks and the oil is skimmed off the top. The mats are emptied of the pits and skins and “re-buttered” with fresh olive paste to repeat the process. This method creates a very sweet oil with slightly higher levels of acidity. The mats add a distinct flavor from the cultures that enhance with repeated use. Many traditionalists believe that this flavor is an absolute necessity to make fine olive oil but considered a defect by enthusiasts of modern president methods, proving once again that beauty is in the eye of the beholder.
The most widespread method used today is the continuous method Olives enter the mill at one end and oil comes out the other. The olives are crushed by hammer mill and the paste is pumped to a malaxer where it is warmed and mixed until the oil begins to separate. The resulting paste is pumped to a centrifuge where the solids are separated from the liquids and the vegetable water and oil are further separated in a final centrifugal process. There are many variations on this basic theme that involve less heat and less washing of the oil. Polyphenols account for the flavor in olive oil. They are much more soluble in water than in oil, so limiting contact with water preserves the flavor of the oil.
The Integral method is virtually identical to the continuous method with the notable difference being that the olive stones are removed from the flesh before the oil and water are extracted. This method has existed for thousands of years but the cost and time to manually remove the stones prior to extraction can be cost prohibitive. There is a slight loss in yield. The Integral method produces a less bitter oil with fewer toxins and waxes as well as the added economic advantage of ending up with four valuable and marketable products instead of one: highest quality extra virgin olive oil, highly nutritious olive water, dry olive flesh for all-vegetable cattle feed, and inedible oil-bearing stones for fuel. The added benefit of this process is the elimination of processing waste which contributes to environmental degradation.
When all the oils appear to be the same and have limited information on their labels, how do you select the right one?
It is difficult to compare taste unless you have the opportunity to open several containers of oil at the same time, not something a consumer usually does. Because of this, the way olive is being sold and marketed is changing to meet consumer pressure for an educated choice, and the opportunity now exists at Olive A’Sudden for you to taste a range extra virgin olive oils, know the crush date and learn about the complete chemistry. All these factors will influence your choice.
Oil season begins in early October and extends to late February in the Northern Hemisphere and begins during April in the Southern Hemisphere extending to June in The very broad geographic region known as the Mediterranean basin is where over ninety-five percent of the production takes place. The area extends from Syria in the east to Spain and Morocco in the west. Spain is by far the world’s largest producer of olives and olive oil.
No two seasons in any area are identical and each producing country has different producing regions, varieties, and preferences for harvest time and style. Many varieties alternate in productivity; a year of high productivity is often followed by a year of rest.
There are as many different olive oil flavor profiles as there are olive groves with layers of variables superimposed on layers of sub-variable and any one or combination can have a profound effect on the flavor and overall characteristics of the oil. Olive oil has a highly perishable nature. It begins to soften the day it is produced and heads steadily down in intensity and brightness. This can only be slowed by rapid harvest to milling onto storage. This makes the production of uniform, consistent, readily available, high-quality olive oil very difficult.
Each producing country has a dominant variety or cultivar historically suited to its terrain, and is representative of the general “style” of the country. A somewhat experienced taster can determine the dominant variety or cultivar of the major producing countries. Spain’s dominant cultivars are the Picual, Hojiblanca, and Arbequina. For Italty it is the Coratina, in Tunisia the Chemlali, for Greece the Koroneiki, and Turkey favors the Ayvalik.
When selecting an oil, search for oils by region, country and variety. Small regional mills are increasingly producing high quality oils.
There is no substitute for a personal tasting experience. We encourage our customers to try as many extra virgin olive oils as they can; quality oils represent a unique taste experience mpossible to duplicate in the traditional supermarket brands.
The variety or cultivar selected for planting will certainly have an effect on the overall flavor and characteristics of the oil, but the characteristics and relative merits of individual cultivars are hotly contested. Although most table fruit is unsuitable for oil production because of yield, size, and oil content there are always exceptions.
This complicated subject is woven happily and inextricably into the unique fabric of the area where each olive variety is grown negating the attitude that one cultivar is superior to the rest. Variety in olive oil as in all things is indeed the spice of life.
Each has its unique characteristics, but some differences are remarkably subtle. Some olives are more durable, while others hold up better to heat. Some are rich, soft and buttery while others are big, angular and complex. The choices are delightfully limitless. Most are not sold as single varieties, except in the regions where they are produced or at specialty import stores. The vast majority end up being part of some generic olive oil blend marketed under any one of dozens of different brands or labels around the world.
There is no substitute for personal experience. Come in and try as many olive oils as you can. When you purchase in bulk from single cultivar stocks you will be surprised and rewarded by the rich variety and quality available at nearly the same price as branded generic olive oil.
