Budget wine drinkers are not getting what they bargained for.

Counterfeit bottles of Yellow Tail, the ubiquitous Australian wine known for its affordable chardonnays and Pinot Grigio, many of which cost under $10 per bottle, are circulating in the U.K. One supermarket in England has even been busted for selling the fake booze.

KVK Supermarket, a grocery store in Birmingham, England, was caught selling 41 bottles of counterfeit Yellow Tail wine, Birmingham Live reported, after one consumer allegedly noticed the coloring was off in a bottle they purchased. The store may be stripped of its liquor license, police said in the report.
