It’s a sour ale fermented with dark red wine grapes, giving it its uniquely deep and rich purple hue. Then it received the signature Lagunitas treatment with a healthy dose of experimental dry hops. This might just shock your taste buds! There just really isn’t anything else like the Dark Swan… it’s a dark purple hybrid ale the takes our house yeast and feeds it some Petite Sirah grapes to munch on. It’s smooth, slightly sour, and superbly strange. Give it a taste, if you dare!
