I always used the fake Modena balsamic vinegar from Ponti, never tasted the real thing.
I'm content with it so I'd rather spend all that money on better meat instead of upgrading the salad sauce.
Also I put a lot on the salad of it so it better be cheap.
The real thing (Aceto Balsamico Tradizionale di Modena DOP or Aceto Balsamico Tradizionale di Reggio Emilia DOP) has a fancy bottle.
What I use is Aceto Balsamico di Modena IGP.
Instead of using cooked must and then fermentating it and then becoming vinegar and making it become over 12 years old, they simulate the flavours and consistency of the final product by mixing cooked must, red wine vinegar and caramel. This is the cause of italians using it in industrial quantities on their salads, it's dirt cheap and tastes good enough.
Industrial wine vinegar just tastes like nothing but acid if you're used to this.
