The Borges brand has downgraded this ACV from properly fermented to 5 % acidity, to diluted vinegar type. It is the only apple cider vinegar in a glass bottle available around, so will stick with it for now. Vinegar is a strong acid that melts tiny amounts of plastic when kept in plastic especially PET bottles, and that does you more harm than good. This borges ACV is great for salads though!
