Query: It taste like vinegar

This is my second product that I purchased from vintner reserve. The first was white wine and it turned out very delicious. The merlot on the other hand turned out terrible. And I followed the directions to a 't'. I've emailed thecompany and I'm waiting for a response. I was hoping to find a helpful review of the product here that could tell me if perhaps I did something wrong or if there was something I could add to fix the wine. I hope I don't have to trash the whole batch cuz that's a giant waste of $$
