People have said to me that when they buy olive oil at the supermarket they feel spoilt for choice. Really?
I have my doubts about this one.
Yes you can find different types of olive oil, but are they really as good as they state on the label? What are we really buying?
Olive oil is like wine, it takes time and experience to understand it but you can get a grasp on the matter and understand some basic concepts which can help you choose a good oil.
When I was on Lake Garda I was given a lesson on how to taste it by the president of the association of the olive oil producers at Agririva Mr Roberto Zampiccoli.
Lake Garda with its mild climate makes it possible to grow olive trees and there is a modest production of olive oil. This olive oil is mild, green in colour and delicate as opposed to olive oil produced in Southern Italy which is more yellowish in colour, slightly more bitter and more pungent in taste (due to the heat and the sunshine).
The spiciness of the olive oil is good and indicates the presence of polyphenols which have health-protective properties particularly against the aging effects and certain types of cancer.
We went up to the castle of Arco which is surrounded by olive groves.
The vegetation looked so very Mediterranean around this area.
There was a distintive smell of Jasmine everywhere. Is there a better natural perfume than jasmine?
We walked up the top of the hill there were olive trees everywhere.
I felt like I was in Southern Italy, the vegetation certainly did not look like the one typical from the Alps!
As soon as we reached the top we sat down and our masterclass on olive oil tasting began.
How do you taste olive oil?
- Pour a little oil into a small glass.
- Cup the glass with one hand and while you warm it up for a minute or two cover it with the other hand to trap the aromas inside so they won’t evaporate.
- Smell the oil: what can you smell? Fresh-cut grass? Almonds? Artichoke? A certain type of fruit?
- Sip a little bit of oil starting from the tip of your tongue and then suck air through the oil and breathe out through your nose then swallow some of the oil. Which flavours or perfumes can you taste?
It is said that pungency and a peppery sensation in your throat is a good sign. You can compare this to the heat of chilies. Sometimes this can be so powerful to make you cough.
Olive oil should always come in a dark bottle as it deteriorates quite quickly. It should not not be older than one year.
When you see olive oil sold in a clear glass bottle with a lovely green colour and it is unfiltered beware as this is done solely for marketing purposes: it looks good and the sediment tricks you into thinking you are buying a genuine natural product.
Industrial olive oil can be coloured using chlorophyll which makes it look really bright green and pretty.
You do not need the sediment (known as morchia or sludge) as this is just the residue which does not serve any purpose and it decays so it is best to buy filtered olive oil.
We were served a very generous tray of carne salada too which is typical from the area. It is raw meat preserved in salt and herbs. Delicious served on top of bread.
When the olives are harvested they need to be pressed within 10 hours in order to maintain their nutritious values and all its vitamins, but some olives are pressed within 4 hours. Most olive oil is organic as the olive trees do not need many treatments to grow healthily.
When you buy olive oil look for the DOP certificate which certifies the origin of the product.
Some of the olive oils you can find on lake Garda are: Uliva which olives are pressed within 4 hours, Olio Cru and Laghel which have won several awards and Madonna delle Vittorie.
A year ago a new EU law has introduced a special anti topping-up cap, which does not allow anyone to fill the bottles used with a different oil not conforming to the original. This means that the oil can only get out and cannot be refilled. This is to prevent restaurants refilling bottles with an olive oil inferior in quality.
I felt I learned a lot from this lesson and now I am more careful when I buy olive oil.
I hope this has helped you too.
What a fantastic view I had of the town of Arco!
