Does white distilled vinegar contain gluten?
No. When people say white distilled vinegar could contain gluten, the assumption is made that any product manufactured from a gluten-containing grain is probably contaminated with gluten proteins or peptides. But to those with some chemical training, distillation is a highly effective method for separating volatile substances such as alcohol from non-volatiles such as proteins or peptides.
