Boom Vinery stallion earns significant increase for next breeding season.

Ole Kirk has been rewarded for outstanding results by his first crop on the racetrack with a fee increase that has him on the cusp of the elite among Australia's stallion ranks.

Vinery Stud announced on Tuesday that the son of Written Tycoon would stand at a fee of $99,000, including GST, in 2025.

That is almost double the $55,000 the Golden Rose Stakes and Caulfield Guineas winner stood for in his first four seasons at stud.

Ole Kirk holds a slender lead over Wootton Bassett in the race for champion first-season sire honours with his 10 individual winners the most by any first-season sire.

Among his top performers are Magic Millions 2YO Classic winner O' Ole, Group 3 Breeders' Plate winner King Kirk and Listed Moonee Valley Pearl winner Prestige Forever.

Vinery general manager Peter Orton said Ole Kirk's fee hike was a result of demand with confidence that his results will get even better.

"Ole Kirk, due to demand has gone up in fee," Orton said.

"He looks to be exceptional. He has three Stakes winners from his first crop including the Magic Millions 2YO Classic winner and he sits comfortably leading the first season sires lists.

"He has a perfect pedigree and offers a complete outcross for breeders throughout the heavy presence of Danehill in most pedigrees.

"The way Ole Kirk raced, we are looking to his late two-year-olds and Spring three-year-olds to dominate, what he has done to date is a bonus and I think the best is yet to come."

Ole Kirk heads a six-stallion roster at Vinery, which has kept the fees for Exceedance ($33,000) and Hawaii Five Oh ($16,500) at the same figure as last year.

All Too Hard, who stood last year at $38,500, has had his fee cut to $27,500, Star Turn has been reduced from $27,500 to $16,500, while Headwater is now available at $6600 after standing last season at $9900.
