South Uist’s Salar Smokehouse is up against a salami maker and a gin distiller in the Artisinal Product final.
Winners from all 19 categories will be announced in front of 800 guests at an awards ceremony and dinner on Thursday, May 23 at the Corn Exchange in Edinburgh.
Scotland Food & Drink chief executive James Withers said: “Every year the Excellence Awards attracts an incredibly diverse range of entrants, all of which are of a very high quality. This year we’ve had a record number of entries and the standard has never been higher.
“While tasting each of the products entered into the awards sounds like a dream, in reality, selecting the very best of the best has been extremely difficult for our expert judging panel.
“Now celebrating its 20th year, the Awards will yet again be the premier night in one of Scotland’s most valuable and successful industries. Congratulations and good luck to all the finalists.”
