The competition, which recognises rising culinary talent from across the globe, will open for entries on 1 February.
For the first time, the competition, now in its third year, will see Central America-Caribbean added to the list of 20 geographical regions already involved and will be held over 18 months instead of 12 with this year seeing the preliminary selection rounds and the local competitions take place while next year hosts the grand final.
S. Pellegrino said the extended duration was designed to allow candidates more time to work side by side their assigned chef mentors to improve their signature dishes and refine their skill set in preparation for the finals.
It said: "Winners of S.Pellegrino Young Chef are given an incredible opportunity to gain global visibility and career development and training, as well as the chance to take part in several of the brand’s annual events around the world, including but not limited to those related to the Young Chef competition."
The competition is open to chefs aged under 30 with at least one year's experience working in a kitchen as a chef, sous chef or chef de partie. All applications made through the website will be considered before judges select 10 semi-finalists from each of the 21 regions.
A shortlist of 21 finalists - one from each of the 21 regions - will go through to the grand final in 2018.
