The new whiskies, which are available the EU “key” Asian markets, are named after their taste and aroma.
Summer Orchard is a 12-year old from Linkwood distillery, Speyside, Billowing Embers is a 15-year old from Bunnahabhain distillery, Islay.
Mellow Mariner is a 20-year old from Ardmore distillery, Speyside, while Fruit Bonbons is a 23-year old from Glen Garioch distillery, Highland.
Each cask was selected and named by the Wemyss tasting panel and industry consultant Charlie Maclean.
There are only a few hundred bottles from each cask and prices range from £55 to £90. These bottlings will be available in selected retailers in the UK, EU and key Asian markets.
William Wemyss, founder and managing director at Wemyss Malts, said: "We continue to have a great response from the whisky community to our single cask bottling and this latest release of 4 single casks has some classic distillery profiles as well as a few interesting surprises in store."
