Final answer:
The vinegar produced from white Trebbiano grapes and aged in wooden barrels is Balsamic Vinegar.
Step-by-step explanation:
The type of vinegar made from white Trebbiano grapes, which is heated and aged in wooden barrels, is Balsamic Vinegar. Vinegars contain acetic acid, CH3CO₂H, which typically makes up 3-6% of its composition. The process of creating balsamic vinegar involves the fermentation of the grape juice into ethanol and subsequently into acetic acid, resulting in a distinct flavor profile unique to balsamic vinegar.
