One of the few 'Tradizionale' balsamic vinegars, the Malpighi is one of the most respected of all the producers of true balsamic. The short, rounded, squat bottle is trade-marked by the official consortium, so unless your vinegar comes in one of these special bottles, it is NOT 'Tradizionale'. The Extra Vecchio is a 25 year old vinegar. The concentration of flavors that results is nothing short of spectacular. Ounce for ounce, this tiny vial of black gold is far more precious than nearly any other liquid. Just a few drops will positively transform whatever cuisine it touches. It is the greatest of all steak sauces; the most unbelievable of fruit finishes; the unquestioned 'secret ingredient' to any soup, sauce or demi-glaze.
