Port Brewing makes a beer with hot rocks. Yes, hot rocks. “Hot Rocks Lager” is brewed by adding glowing hot granite to the brew kettle. In doing so, the rocks cause a “super boil,” caramelizing the sugars. The result is smokey toffee & caramel. According to Port, these wouldn’t be prevalent in a normal boil. Hot Rocks is a spring seasonal, first released in 2009.
Hops: German Magnum, Tettnanger
Taste Expectations (Per Port): The flavor is a robust dark lager with layer upon layer of caramel sweetness with just enough hopiness and malt to prevent it from being cloying. The finish is sweet with toffee and cocoa notes and a faint dryness.
Availability: 220z bombers. Early Spring seasonal.
