Juniper Black Ale Sierra Nevada 8.5% ABV Beer Geek Nation Rating: A Beer Advocate Rating: B+ Rate beer Rating: 100/100 Mephistopheles is the crafty shape shifter, the second fallen angel. Amazingly complex, coal black, velvety and liqueurish, this demon has a bouquet of vine-ripened grapes, anise and chocolate covered cherries with flavors of rum-soaked caramelized dark fruits and a double espresso finish. Mephistopheles is the final installment of "The Demons of Ale" series.
