Extra-virgin Olive Oil: the Green Gold of Tuscany

Extra-virgin olive oil (or, EVO oil) is the result of mechanically pressing olives without any chemical processes, to ensure the purity of the product. To be classified as extra-virgin, the oil must meet strict criteria, including the absence of organoleptic defects. 
In particular, extra-virgin olive oil is distinguished by its superior quality and authenticity. Indeed, this oil is produced exclusively from olives grown and processed in Tuscany, following strict specifications that ensure respect for local traditions and the unique characteristics of the territory. 

A quality extra-virgin olive oil can be recognized even before tasting it. The color can vary from deep green to golden yellow, although the aroma and flavor are what really count. 
Tuscan extra-virgin olive oil releases fruity notes on the nose, hinting at almond, artichoke, freshly cut grass and ripe fruit. 
In the mouth, it is harmonious, with the right balance between bitterness and spiciness, two characteristics that signal the presence of polyphenols, being natural antioxidant substances. 

Tasting extra-virgin olive oil is a sensory process involving sight, smell and taste. 
The best way is to pour a small amount of oil into a dark glass, covering it with one hand to warm it slightly. After a few seconds, conduct an olfactory analysis. Quality oil has fresh, vegetal aromas. Tasting is done by taking a little sip and distributing the oil in the mouth, letting a small amount of air pass between the teeth. 
A good EVO oil is harmonious on the palate, offering up varying degrees of intense bitterness and a slight tingling in the throat, as hallmarks of freshness.

To make an informed choice, it is necessary to read the label carefully. It is best to opt for oils with a certified Indication of Origin, which guarantees traceability, quality and provenance. Four protected Designations of Origin are produced in Tuscany: Chianti Classico DOP, Terre di Siena DOP, Lucca DOP and Seggiano DOP, along with a Protected Geographical Indication, the Toscano IGP, which can be produced around the entire regional territory. 

It is advisable to avoid products with too low a price, as a quality extra-virgin has high production costs. 
It is also a good idea to check the harvest date, which is more indicative of freshness than expiration date alone.
