It's a new way to apparently add flavor to beef.
ABC news reports, some French farmers are now serving their cattle up to two bottles of wine a day, claiming it improves the taste of the meat.
It all began with winemaker Jean-Charles Tastavy, who had heard of studies in Spain and Canada that showed the benefits of a happy cow. With the help of farmer Claude Chaballier, who had a surplus of cows, he decided to test the theory, Agence France-Presse reports.
They started out slowly. In 2011, the pair began feeding three cows pomace, or diluted pressed grapes that were left over from the fall harvest.
After a while, the cows were given the good stuff -- up to two bottles of wine per day.
And although it sounds like a lot of alcohol, Tastavy said the amount of wine given to each cow is based on official recommendations.
