It's a tradition at the Indianapolis 500: the winner of the race chugs a cold bottle of milk to celebrate the victory. 

The American Dairy Association of Indiana released a list on Friday of the milk-drinking preferences of each of the 33 drivers who will be participating in Sunday's race.

The tradition is said to have started in 1933 when winner Louis Meyer asked for a glass of buttermilk after his victory.

The Association released a statement along with the drivers' milk preferences. 

"Since 1933, Indianapolis 500 drivers quench their thirst with a bottle of ice cold milk from our Indiana dairy farms," the statement reads. "For the 99th running of the Indianapolis 500, the tradition continues."

Overall, 15 of the drivers selected whole milk, 14 selected two-percent and four of them picked fat-free milk.

The 2014 winner, Ryan Hunter-Reay, will be going with the two-percent milk that he drank last year.
