Thank you for the answers! Araujo and Grace are vineyards that are producing really good Napa wine and they have a little production of extremely flavorfull olive oil. Armando Manni oils are considered to be the best olive oil in the world and many of the best restaurants use it such: Charlie Trotter, The Fat Duck, Per Se, The French Laundry, Jean-Georges, Trois Gros, La Pergola and way more. So I am really suprise to see that every places I went in Montreal (including LDduM, Olive & Olives) even don't know about this oil. Prunatelli is just a other really well reputated olive oil from Italy.
