Over the National Day holiday, tourists poured into Shanxi, China's "vinegar capital," to drink, what else, vinegar! Beverages of both sour and sweet varieties, and even a 10-year aged brew mixed with honey had visitors hooked. In Qingxu, travelers watched artisans produce vinegar using traditional methods, and snapped selfies with a backdrop of 10,000 giant vinegar jars. After years of "summer sun and winter ice," this liquid gold turns into rich, tangy vinegar. Would you dare take a sip?
