Due for release on the 26 February, the oyster stout has an ABV of 5.5 per cent and is based on a recipe for their salted caramel milk stout.
The oyster stout has been made in collaboration with Edinburgh's Bow Bar and will be priced a £3.30 per 330ml can.
Describing the process, the Fallen Brewing team say: " The oysters were shucked, shells added early in the boiling process with the meat and brine added late.
"The shells and liquid inside the oysters add a wonderful briny, ‘sea-water’ character while the proteins in the meat add to the already luxurious, soft, full texture of the beer.
"It has a sweet but clean aroma on the nose with a rich dark colour and a firm white head, delivering a fresh sweet and rich malty flavour with a clean ever-so-slightly briny finish."
Oyster Stout will be launching on 26 February in cask at the Bow Bar and online.
Established in 2014, Fallen Brewing is situated in the old Kippen Railway Station with views towards The Trossachs and The South West Highlands. The range is made using only pure, soft Scottish mountain water and the best hops and malts from around the world.
