The grits were presented in 2-pound trays, each about 8x6x1 1/2-inches.
Bertoletti, in a statement, said the race "tested our stomach capacity like no other."
Tim "Eater X" Janus of New York was second, with 20 pounds. Joey Chestnut of San Jose, Calif., who this summer ate a record-breaking 66 hot dogs in 12 minutes to become world hot dog-eating champion, finished third, polishing off 19 pounds.
The top seven eaters split $10,000 in prize money.
