Raw apple vinegar is made by secondary fermentation, usually referring to liquid fermentation. Liquid-fermented apple vinegar is made from concentrated apple juice or fresh apple juice, which is fermented into high-purity cider, and then inoculated with acetic acid bacteria for acetic fermentation to metabolize alcohol into acetic acid.
Apple vinegar is made from high-quality apples or apple juice by microbial fermentation twice. Then, according to Luyuan's unique production process and formula, raw materials such as white sugar, honey or xylitol were added to the original apple vinegar, and after careful blending, the apple vinegar beverage which can be directly drunk was made.
