Cassandra from Siphon Brewing is an oyster stout at 7% ABV, brewed in Damme, Belgium. The beer takes its name from the Siphon restaurant, whose oyster shells are incorporated into this stout, creating a distinctive link between brewing and local gastronomy.

Cassandra is a complex, full-flavoured beer. Its bitterness derives from both its coffee-like roasted grains and earthy European hops. The result is a balanced stout with pronounced roasted character and a dry, lingering finish.
