As you and others have stated,there are different brands of that kind of oil and they will taste a bit different.Some do not taste very well from the bottle,but shine when adding to a sauce or to a pizza.
Also,one thing I learned,even if the bottle says Imported from Italy,read the label.It may sometimes say the product oil is derived/comes from Countries such as Italy,Turkey,Greece,Tunisia,Spain or etc.Those countries have stamped letter codes. For example, I have a small bottle of DaVinci EVOO.
The cap itself says Imported from Italy.Yet on the label,it reads the oil may have come from one of the following countries: the ones I listed above.The stamping codes are I=Italy,SP=Spain,TN=Tunisia,TK=Turkey,and GR=Greece.
The product stamping on top of the cap I have right now,with the dates and etc, says SP which =Spain!
So the oil is from Spain but its bottled in Italy.
Yet the ads can be misleading saying its Imported from Italy.It is not lying,no,but most of us that buy it will auto-assume its all from there!I'm sure the marketing Teams are aware of that!(Unless we read the label print and check the codes)
I have found some differences in taste when using these different Oils supposedly from Italy but many are not actually from there.I am not saying the Oil has to be from Italy to be the best,but so far,the Better OO,or EV-OO bottles I have tried that actually came from Italy,were the best.
One of my favorites is sold through the Food Lion Food stores,under the brand name of "Tastes of Inspirations",and as far as I know,the oil is from Italy.Its very good.I have fried breaded chicken in it and the smell and taste is incredible over say,canola oil or veg oil.
When I make chicken parmigiana,and bread crumb the chicken in Italian style bread crumbs,I prefer the OO over the canola or vegetable to fry it in.It infuses it with flavor not found in other oils.
The oil you have can very well be from Italy too,but this is something I wanted to point out to people online to know that there can be differences from different countries,and the cold press process made to make olive oil can vary from place to place.
OO is alot like tomatoes...we try many different brands until we find the ones that make our pizza and sauces better than what any other store brand can offer.
I wanted to add,lastly,just tasting the oils from the bottles can be unpleasant for some.Same as Vegetable oil...we never really take the time to taste them out of the bottles,but we know what it can do for our food.
What would fried chicken be without some nice hot canola or veg oil to fry in?Yet taste them by themselves,they dont taste very good.
Cooking with it is key.
